Nice. My whole setup, VPN server for inbound connections and VPN router for outbound connections are all VMs.
Shit. My whole setup is one RPI3b, and ASUS RT-AC51U
I want to get a pfSense VM for more advanced stuff, but right now Turnkey Linux VMs are getting the job done.
I could easily setup some VMs to to the trick on one of my PowerEdge R510 but at 220ish watts at idle, it would definitely be overkill imo
I mean - that RPI3b and my router is doing the job for me
RPI's handling the dhcp, dns cache, and my home AD DC (on samba4)
I have a PowerEdge R510 handling Steam cache, a small samba storage (it have about 4TB of storage) and some other random stuff (including some Docker containers for Ubiquiti UniFi and UNMS)
small samba storage(it have about 4TB of storage) yeez
I say small because I don't have any use for it ^^'
My experience using a RPI for remote network access is that they freeze up kind of often.
And I just told you for the one which is already setup, but I also have another 4TB PowerEdge, another at 3TB and another one at 1TB ^^'
Chrizzle, that's why I'm not seting up the VPN on the RPI - I'm doing it on the router (and offloading the router, with rpi)
I see that now that I re-read your comment.
I wanted the Pi to work for phone-home type scenarios.
Look at all those servers (which only costs me... a bottle of Jack's)

Like leaving one at my mom's house for simple tech support.
You can try to find something more powerful than rpi, with the same form factor
I don't have any pics here at work, but I use a stack of old think center desktops running proxmox for my "servers". I use the term loosely.
I may use a Intel NUC (those higher grade ones) as a NAS one day, even if it was my first plan for a VPN gateway, but they are expensive af (it would have cost me less to use one of my PowerEdge for this, including electricity, if noise wasn't an issue...)
I don't have any racks and the primary space of all my gear is on a desk, so size + noise is an issue too. Fortunately desktops stack on top of each other π
I use a low end NUC for my HTPC. It's slick, but an unforeseen issue is that my toddler loves to steal it. So it spends a fair amount of time in a toybox.
The bright blue light on the power button gets him every time. Like a moth to a flame.
can you share a nas between 2 subnets with only 1 NIC?
With some manual routes and IPs it should be feasible
There are a number of ways depending on your network.
like to be able to use your nas on the security camera subnet and on the other pc subnet
@high anchor I need to setup proxmox on my server π
I wish I had some more servers π
@subtle glen
If you have a managed switch you could do vlans. Put the NAS in both the internal and camera vlans.
if your cameras are on the same physical wiring as your NAS, just with a different IP schema, you can just add a second IP to the NAS' network interface.
If your camera network and your internal network share a router (like the Edge Router mentioned above) you can also allow traffic between the router's network interfaces with some firewall rules. I did something similar years ago with OpenWRT.
but TBH adding another NIC is often the simplest solution.
unfortunately for now i will be using a nas box
Firewall rules it is π
it would be something like this. (there are other devices and switches but they are not relevant)
Paint π
where's the cloud that says "Internet" π
whoops
No network diagram is complete without one π
LOL π
do i also need to add the phone line cabinet/the isp/the backbone to the exchange point etc
I only say that because I am in network design hell with Proxmox and bonds and vlans.
just use paint
if it's too complicated ill just use that nas or something else only for that camera
It's more the conceptual part. Binding interfaces together for speed/redundancy and then splitting them back up with vlans.
do you need the camera to talk to the internet?
for remote access i would say. Or have it locally and remotely connect to it via vpn (as soon as i get better internet speed)
Or use SSH to tunnel to it.
π€
Put a RPI or a VM somewhere and forward a port to it. You can open ports with it that will use the tunnel. Dynamic, local, and remote.
Telnet all the things!
It's a Swiss Army knife. I use it to tunnel Remote Desktop, VNC, browser traffic, you name it.
SSH will let you do the top 20% of the things that you would use a VPN for about 80% easier.
I guess you have to open port 22 on the router right?
If your ISP will let you. any TCP port that you can remember will work tho.
and then connect to the NAS (in this case) using your public ip?
and route the port 22 traffic to the nas ip?
Yup. Or use a high numbered port and forward that to port 22 on your nas.
There are a lot of things that scan for port 22.
can i choose any number for the port?
or 8357875 ?
TCP/UDP ports top out at like 63 something.
sorry, 65536
I knew there was a 3 in it somewhere π
you mean that after 65536 you are sure nothing uses the port you choose?
anyway, if you pass port XX on your router to port 22 on the static IP of your NAS you should be all good.
I have no idea what happens after port 65536. But I bet your firewall software will throw an error if you specify something higher.
unsigned intergers and whatnot.
yeah the tab where you put the port becomes red
I'm sure that was a "64k ought to be enough for anybody" type of decision. like IPv4.
"connection refused" thats a good sign π
you using *nix ssh or putty?
Your ssh server is either not listening on 22, or the port you're using, or not configured
lets see
Does the app let you specify a port?
π story of my life!
I use VPNs too. they just take a lot of preparation.
SSH is great for those times when you aren't prepared.
BTW, on your firewall setup did you specify TCP?
for the port, i mean.
i changed the SSH port on the NAS, i opened the port on the router (TCP/UDP), port forwarded even on the NAS (even tho i think it's useless), put the NAS ip to tell the router where to send the traffic
ohhh fiber, where are you
Dude, I know nothing what can be wrong
I like to use SSH keys and disable password logins because I'm a delusional paranoid. Though SSH keys without passphrases are great for automating SSH connections.
But have you tried turning it off and back on again?
^^^
SSH servers should have disabled pasword login after first time setup
Or at LEAST disabled root password login after first time setup or just... by default
I agree. I also like to use Fail2Ban as well. Probably a "belt and suspenders" approach.
I use fail2ban on any public SSH server
Every linux distro ISO should contain "Linux best practices"
I have no idea what the rest of the best practices are, just locking down SSH. π
A good firewall
I mean - not only "SSH best practices"
If you have a web server, rate limiting
with exactly one port open, which is SSH π
public key auth only
Fail2ban, never using 'chmod 777'
Disable root ssh
Not everyone can use cloudflare :p
I can't afford different machine for different services
My server is running everything - web, mysql, mail, vpn, ts3audiobot
Oh, and MySQL should only allow local login. NEVER expose your MySQL instance π
^
I can't be trusted to put all my eggs in one basket like that π That's why I like VMs and containers. So I can snapshot all the things before I fix them.
I mean - "reinstall" used to by me button of the choice in the panel of this dedicated server
I often end up fixing them so well they need to be restored from a backup π
And then I've mastered the reinstallation of everything and know I know whay NOT to do
I have a hosted Asterisk server.
and a plain debian box with a super cheap/mildly shady host that I use mostly for SSH.
I've got plans to buy rack servers when we move to new house (which will be in I dunno? 10yrs?) and move my stuff there
I think the same thing. Mostly because I look on ebay and see rackmount servers with gobs of RAM for less than the price of a nice video card. But the startup costs for racks and panels always bring me back to reality π
Although I have seen Ikea end tables used as racks.
chrizzle - look at one thing
power consupmtion
most of the old but very powerful server, are pulling heck of a lot power
XD

r/linuxmasterrace
Could putting an ethernet plug on a plug extender mess with the connection
or possibly slow it down in anyway
is anyone else having problems with the asus pce-n15 11n wifi card
of my 100 mb connection i only get around 30 mb
What do you need help with?
i download game form steam but i dont see traffic on nload app
and i work by all the stages on the the tutorial
Have you configured 'steam cache server' as your dns server?
yes
i work with docker as the tutorial
any idea why ?
can u help with share screens ?
Man - I've never deployed the steam cache server, so I'm just doing 'light' troubleshooting
mmmm ok
i will keep working on it ty
i found the problem the DNS script keep crashing : /
@thick minnow what do you mean by extender? like an in-line coupler?
^ thatll work if you dont go above the rating of your cable
i use those to quick swap cables where the switch is
Iβm thinking he means putting a power line adapter at the end of an extension cord. Basically anything can mess up powerline stuff but an extension cord is not too bad. Try to stay away from power bars as those are the worst.
actually if some plugs are connected to the same junction box or breaker they make a power bar π
i'm surpised that my powerlines works even tho the signal has to pass where a lot of other power cables are
Having anything plugged into the same circuit/phase (depending on how the wiring is set up) can mess it up or slow it down
yeah if there are a lot of things nearby, that can drop the signal
I have had a lot of trouble with powerline adaptors
i usually get a link speed of 200 or less mbps between the powerlines. And those are "rated" for 1000 mbps
no replacement for wired :(
^
i use those things
Thats a good place for a serva
who needs expensive racks
ikea furniture
also $80 rails
ah yeah
and keeping the servers in your bedroom = easy access for when you mess up the switch config and need to swap ports
and they are also a good heater in winter
My pc is allready a good heater
my switch is a good heater, cant say the same when its 30 degrees inside
XD
That reminds me that I need to get some rails myself for my server
use some bamboo sticks
My server is going in an actual DC so sadly I canβt do something like that. Itβs quite heavy too
I like my servers to be silent, quiet and invisible.
And thatβs why I am sending mine about 795 miles away
:/
has anyone a list of IKEA furniture to make a server rack?
it's quite a mess in my room now :(
i use it
use what?
hahahahah
I'got an old 2950with 16Gb and two Xeon X5550
you need a bigger table for that
I really feel like internet in USA is quite sketchy, not anyone has the same solution to access internet, in France we got "insert telecom company nameBOX'es" that do TV/INTERNET/PHONE/router/Wi-Fi hot-spot/DHCP server/ethernet switch... and that's it behind this you can build whatever network you want... and manage your box in an web based interface...
yup, @rocky badge
you like those?
π
@sturdy mirage they're old and loud but work lol
But I have charter and I use their modems and tv boxes but otherwise everything else networking is mine
blob! :D
zbk!
you just described alot of cisco things under $500
uuuu
That is true π
the only downsides are the small amount of ram slots and the really old Java based IDRAC interface
i use ie and Java 6
These bois use Java too
eXPloREr??
HP β€οΈ
yeah
real men's use procurves switches
mmm
some
like a hummmm
hummmm
I installed proxmox on an old 2950 @sturdy mirage
what is proxmox?
Virtualization stuff
oh yeah I heard about this like... 3 month ago
I've never tried this... is it well supported?
π
I use VMware Esxi6. 5...
Yeah it's supported
@brittle mural are you from France?
No, why?
i use esxi 6.5 too
I thought, sorry :)
I would use ESXi on this server but the CPUs aren't supported by ESXi
It's alright.
seriously? @rocky badge ESXI even accepted my I5 650 and E5110
esxi accepted my i3-2120
X5355s don't have SLAT
did you try 6.0?
oh men too bad
Yes
I got one E5110 left for sale if you want
Currently I don't have thermal paste π
So it's CPU and the heatsink, no thermal paste in between
nah
I'm gonna buy some soon
I have tried mayonez
lol
woops
since it is really greasy it works quite fine..
i prefer toothpaste
easier to apply
i even re used the thermal paste on the heatsink few times
only one time... but AMD A10 6790K didn't liked it...
it burned out
works fine for 5 minutes
i feel like i could fill up its capacity with a 24 h video
with segate enterprise drives
there is never enough storage
12 TB?
for one camera π
you don't want to know how much storage it requires for 200+ 1080p color cameras
what's the LCD screen for tho
Data and info
how is it connected to the motherboard
ah yeah @fresh copper
2 100 gbps link aggregation
π€
too little?
Only two? Needs moar
it records 2560x1440 footage, it can saturate that easily
Lmao
i think the lcd is to check if the disks are ok. I'm watching a video and it shows on the LCD "disk 01 OK disk 02 OK"
seems legit
@fresh copper lol an 8K security camera
i need it
couple of them
some things happened in front of my garage
like when someone put a big ass lock on it so that i could not open it
200x zoom
I'm still thinking that HP has found the best way to put disks in a rack....
https://youtu.be/CIY0l8CYjlA
Not many years ago a few terabytes would take up a whole Rack. Today I stuff in 500 TB in this 5U HPE D6020 Disk Enclosure. With the 70 drive bays and the ne...
this channel is really good I think
in Europe we manage to have very cheap server stuff there is a lot of companies an brokers that Sells refurbished electronics
caps are illegal in a e s t e t h i c text?
server monkey got HP and dell caddies for 5$
what is it for networking?
Looks like xfp?... I know it's not sfp(+) and doesn't look like qsfp to me
looks like xfp but have you got a photo of the pins in the connector on the card to be sure
pretty sure it's XFP. is that a better version of sfp+ ? I see that it can transmit 10 gbps like sfp
is it fiber channel maybe?
that's a 100 gbps NIC
XFP for higher speeds of 100gb
ohhhhh
maybe its just hte angle but it looks wider than XFP
Woo
lol some one made a monster out of Blob
π
does any one know if a speed test server records a local record of a speed test?
You sure that's XFP and not QSFP+?
What I meant was
Would a plug extender like one of these
If I had an Ethernet plug plugged into it
would it limit my speeds n such
Anyone?
@subtle glen Yah, that's QSFP+/QSFP28 for 100G, XFP was used for 10G but never went beyond that
@thick minnow like powerline?
Yes
if I put an Ethernet plug in it would it like bottleneck my ethernet
It just extends the pain socket making more plugs
Yah, it definitely could
Not to say it will but usually they will cause a lot of issues with powerline in most cases that I've seen
so I should plug my Ethernet directly into my socket
instead of using an extender like those
Yah, I would definitely recommend it if possible
also with that green led i would say that is a surge protected power bar ( that filters the powerline freq to ground)
@clear igloo is there a faster connector? OR QSFP+ is like the max you can get
QSFP for now, QSFP-DD and OSFP are coming for 200G and 400G with QSFP-DD being the better choice due to more dense port configurations and the option for compatibility with lower speeds on the switch ports
@split spire it's also about "finding the best plug". One that doesn't have a lot of stuff plugged in or that is not connected like a chain to others
holy shet 400 gbps? wtf
Yah, most of that will start showing up towards the end of the year from what I've heard
does cisco sell switches for that?
I'm sure there will be another connector for application specific stuff but industry standards are between QSFP-DD and OSFP from what I've seen
They will be, yes
i wonder how much it will cost
Couldn't say right now
are those QSFP fiber cables?
so sea cables landing points have these
SM is for long range, yah and can do higher data rates on the single beam of light
so uhhh where do i sign up
I think that IPsec will drive me crazy.
This thing don't want to work, for no apparent reasons, and log is not even trying to help me...
(It may be because I don't have an usual setup, which is a IPsec site-to-site VPN with one end behind a firewall, which should work fine because of NAT-T...)
I'll try with a pfSense box (as my "behind NAT" client)
Hmm
I mean, I have a spare R510 just at my left, so why not trying to see if with 2 pfsense boxes, it's working ?
(Installing a pfSense on a PowerEdge R510 (a freaking dual-xeon) feels so wrong, even LMG one wasn't that overkill compared to my pfSense (test) server...)
you are never too overkill
Yay, my mute finally is gone
Once you have a lot of interfaces (as I do with so many VPN connections) especially ones that need encryption like OpenVPN and IPSec, it can take a lot of CPU power
Were you muted?
there is no best router to get.. its just what your needs are and how much are you willing to spend..
with that said i like the ac1900 nighthawk. but there are others that are better. and it depends on how you intend to deploy it.
I use an edgerouter X at home
Or do the linus approach with the janky pfsense build
π
With a pure router you have everything from an Edgerouter X to multi 100Gbps routers.
For a wifi router (what you are probably looking for) there are a lot of options. I like the Ubiquiti Amplifi line but you might want the Linksys WRT3200 ACM if you want OpenWRT. For something slightly less expensive than the Ubiquiti Ampifi stuff is the ac1900 nighthawk that The Shadow mentioned. That crazy eight anntenaed ASUS router is apparently pretty good too
If you give me some thoughts on price range, size of home, and if you plan on learning networking I can give better advice
agree.. the Linksys wrt3200 is very nice. and asus do make a damn fine router.
i have the basic trash form att
i just need to know what i should get
my family is all ways on iphones and im the only one on a pc and i want to play lol and stream
B_M_Wilson asked some questions of you deadpanther, he asked" If you give me some thoughts on price range, size of home, and if you plan on learning networking I can give better advice. " this would help us better help you.
Hi, I saw someone talking about a nuc for a home server...
i can spend what ever
I own a NUC and use it as home server
it is a Celeron N2830 with 4GB ddr3l and 500GB hdd
and do i need to replace the modem too?
it has several services, such as:
transmission
samba
ssh/sftp
tvheadend
minecraft server
garrys mod server (not much players)
UT99 server (very light)
Quake 2 Server (very lght)
it is running ubuntu server 18.04 lts
planning to add owncloud and openvpn
NUCs are awesome!
@sick crown generally you canβt replace the modem but some US ISPs allow it. Itβs not something I really recommend because there is not a lot of benefit that the average person would find. I think you are probably best going with either something like the ac1900 nighthawk or the ASUS one. If you are in an average sized home (as apposed to an apartment) then I would probably get a Ubiquiti Amplifi. Only downside is that you canβt get it in many stores, you would usually have to order it online.
i was looking at this NETGEAR XR500 Nighthawk or MikroTik hAP AC RouterBoard
sure get that xr500 nighthawk looks sick
how much would this make my enternet better that is my question
it depends on a few factors. like how big the house is and where you place the router. also if the channels used are also being use by others, like if you live in the city or apartment. range should be alot better then what ever the isp gave you. you may want to look at what other networks are around you to make sure you are on a deferent channel.
I'd go with the MikroTik RouterBoard
i can give you my area so you can look 
Are there any rackmount routers under $150 that are any good/gigabit?
there are apps for android and iPhone that will scan the local Wi-Fi and show you what channels are being used.. and its free.
personal preference imo.
@thick minnow Have you checked Ederouters?
lets take a vote on what one you guiys would piclk
Oh that's the $300 pro model
im not voting on it... take my advice or not.. its you money and your network.
^
hmm
blob your profile picture is adorable
what is the diffrents from the two? sorry im not very smart
I probably would not go with the RouterBoard just because I think you should stick with consumer oriented routers as they are easier to set up and can do things like channel searching for you. They are not as good as the higher end stuff but way easier to set up.
@thick minnow You can get SFP+ Edgerouters (the Edgerouter Infinity) but they are way more than $150. If youβre fine with just normal SFP there is the Edgerouter X SFP, or if you want rack mount, the Edgerouter Pro which is still probably outside your price range. There is a rack mount kit you can get for the Edgerouter 4 and 6P which both have SFP ports but run $200 and $240 respectively. If you are willing to sacrifice rack mountability then the Edgerouter X SFP is the best, it has 5 1000base-T ports and one SFP port. If you have access to a 3d printer then there are rack mount kits that can be printed.
Thatβs basically it in terms of Ubiquiti stuff. I am sure there are options with other manufacturers that I am less familiar with. If you have any Ubiquiti specific questions I can answer those best as I use a lot of their equipment for work. I am happy to try and answer any other networking questions too as I create and manage networks for work so I have a decent amount of experience.
@sick crown I'm also going to have to lean towards the Netgear (or ASUS equal you can afford). I wouldn't recommend a pro / enterprise type router for the entry level networking person.
There's also the Ubiquit Amplifi stuff if you like mesh networks
My cousin had the X6 and that thing was a beast.
i need something to replce this all inone trash
yeah, I'd first check with your ISP to see if you can replace the modem with your own
Then just get one of the ASUS or netgear routers you mentioned above. Even the X4 nighthawk is plenty.
Just make sure you set up QoS to make sure your gaming has some priority over general traffic so you don't get lag spikes, etc
You can have your own modem?
A number of ISPs in the US allow it
Yah, for cable I believe by law they technically have to allow you to use your own if you want
are there any diy ("self-hosted")modems like pfsense is to routing?
Nothing that supports DOCSIS 3.0 and up
Yea, you have to have a separate modem and router if you want a good router
The DOCSIS 3.0 and 3.1 stuff has proprietary drivers so pfsense and the like canβt easily support it. Not to mention but those in Canada (where we usually canβt use out own router) are not likely to work on a version of those OSs for stuff they canβt use
Well 2.0 is basically dead at this point and not supported on any ISP that's half up to date on tech
DOCSIS 2.0 also didn't support channel bonding so it supports maybe 40Mbps of down and 30Mbps up (roughly) wherease 3.0 supports up to gigabit down and 200Mbps up (in theory)
3.1 can do up to 10Gbit down and 2Gbit up but there is also 3.1 full duplex which can do 10Gbit down and up
ah
New switch installed π
What kind of switch? Iβm waiting to get my Cisco Meraki one that I got for free.
?
That's the one
lol
We ended up with a couple extra in the lab and long story short, I got to take one home as part of longevity testing π
:O
Since most of our testing involves constant reloads of the box for all the changes and whatnot and just having a box without traffic going through it and just sitting there isn't exactly the best test, this gives us the chance to see how the code holds up over a long period of uptime with traffic and whatnot going through it that's more typical of what might be seen in production
How can I smarts?
Give brain 1 injection of "the dumb" and get much smarts-o
Lol
"Budget option"?
Yea, they give out the 8 port one. I hear that itβs ok. Probably better if you actually have a bunch of them but apparently having just one for a hobbyist is not the best. Apparently you can get their AP and firewall too. Not sure how much use I would have for the firewall but apparently the AP is quite good
Yah, the AP was pretty solid. Firewall was nice but just didn't have much throughput, at least the one I got. I've swapped out the AP since I got it as it was only 802.11n
do cisco switches have multiple POE voltages? If you plug in any 24/48 V etc devices in them will it work?
I didnβt know it was only 11n. Iβm only planning on using it as an auxiliary one in my garage so itβs not like it needs to be 11ac
Well this was about 4 years ago so they've probably changed the models they give out since then
Thatβs possible
It looks like the specific switch is the Meraki MS120-8LP 1G L2 Cloud Managed 8x GigE 64W PoE Switch
Ah, so they have changed it for sure
I just checked and the one I've got is the MS220-8P
Definitely don't see the AP I got on the site though so that's probably discontinued and they give out an AC one at least
Hey guys I am wondering if someone can help me with a network issues. I have a wireless modem that I got from my isp and it does not quite reach the room my computer is in. I just bought a wireless router and wanted to know if i could use the wireless router as a extender
Most routers can do that. If you tell me the model I can see if I can find the exact instructions
Isn't it just as easy as plugging the router into the modem, and setting it to "AP mode"?
Spent an hour trying to figure out why my water leak sensor wasn't connecting to wifi. After trying everything and finally getting it to connect, it turns around and disconnects but then I sent an email to support and not a moment later it's back up and working π‘
Have no clue
It was refusing to accept the DHCP offer and never picked up an IP for some reason
Odd
Yah, just randomly decided to accept the offer and now it's working but it worked fine for almost 3 months from the time I got it until yesterday
does it come with a 90 day money back warranty π
Nah, it's got a 1 year warranty π
Noice
Finally upgrading from my ISP modem, and am moving my personal router to be an access point on the other side of the house instead of using the likely less powerful extender as one.
Getting this one: https://www.netgear.com/home/products/networking/cable-modems-routers/C6300.aspx
Have you bought that one yet? If not I would look at something else because it's got a Puma 6 chipset which will add a good bit of latency and other issues
Yea, those Puma 6 chipsets are not so fun. If my ISP did not force me to use a modem with one in it I would switch in an instant.
$70/mo for 4 (3) mbps .-.
Ouch
I use Ethernet
Ethernet is nice, big fan on 1000Base-T myself but I here 1000Base-LX is nice too
Ya they are both pretty good
10Base-T or bust π
iSCSI mounts ftw π
How secure is something like a pi hosting openvpn on a corporate network
@harsh rose Is the pi connecting to an OpenVPN server or is it the server?
There are always security considerations and it depends on what you are planning to do with it. Ifβs itβs for remote access then it should be ok as long as only the people that you want to be able to connect are given credentials. If itβs connecting outbound itβs more of a concern. It should be fine on itβs own as long as itβs in layer 3 mode and uses a different subnet but there still are some potential attacks. A lot of those are dependent on the exact environment.
Regardless of what the setup is, the only way to be fully safe is to essentially treat it like another WAN connection. Put a firewall between it and the rest of the network and only allow through what you have to.
maybe if it's something you play with, you can simply put it in DMZ environment
Anyone in here know much about STP?
Spanning tree is evil π
I'm working on configuring one of my switches at the moment and I am wondering if I should use regular STP or RSTP or MSTP
RSTP or RPVST is most common
MSTP isn't something too common these days and STP is pretty much out the door in 99% of environments
Thanks. This one is just for my internal network so I want to make sure it's most likely to be compatible with whatever random equipment I use in the future.
Yah, RSTP will work with STP too if you happen to have a switch that can only do that and gives you more flexibility with regards to configuring edge ports which STP doesn't provide. Been a while since I've messed with plain STP so I'm a bit fuzzy on that part
Ok, Iβm sticking with RSTP then. Thank you
hey guys how i can tracing my network on server that i build on linux with docker ?
@gusty vault What do you mean by tracing? Like traceroute? Are you wanting a docker server that scans your network?
Things that can help me understand include: What are you trying to accomplish? What have you tried already? When you tried these things what did you expect to happen? What actually happened?
hmm i mean something graphic that i can see the traficc of outgoing and in going data to server π
Oh, something like MRTG is probably what you want. It creates graphs of network interfaces. Here is an example of some random ones (they can look better than this though) https://evix.org/mrtg/

@fresh copper
That would be nice. They mentioned it was some sort of diagnostic panel. I wonder if it's built into one of the containers. They don't mention it on the forum post though
maybe they used some site to connect the server
ohh nvm i will find something :/
ty for the help @fresh copper
You're welcome
@clear igloo yes sadly
its one of the better modles compatible with my isp
and its overkill for the speed I get
by 2 times
@gusty vault The tool used for the graphs and such in that video is called netdata. https://my-netdata.io/
@gusty vault as noted above, it's netdata, a stats dashboard you can install on linux systems that has a web interface. i run it on my potato "server" AKA a mac mini G4 from 2004, running debian on a single core ~1GHz PPC cpu with 1GB RAM.
Wow ty
@ornate jungle Netdata ftw!

ok well I enabled logging to see if I could get the error so it wasn't just a restart π
man they don't log speed tests to the log file either
and back to failing when I turn logging off the SSL fails again... wtf Ookla...
something is wrong today
This is so sad
I know that some people survive on those speeds but that ping is a nightmare
@subtle glen looks like EDGE π
That sounds about right
Nice!
Iβm waiting for some cool stuff myself
I got to decide what IPv4 subnet to use for my new LAN network. Iβm thinking 10.10.10.0/24 because why not
192.168.1.... π
I may want to change ip ranges too but I'm too worried about changing all the static ip's (especially the one from the cisco switch)
@fresh copper what cool stuff
Anyone in this channel work with honeywell door security panels. Trying to setup one to be accessible on my local network and hagving some issues. Ping me if you can help

How do you put a router/modem combo in bridge mode ;-;
Like this?
I am very very sorry
For a more serious answer: You have to refer to the manual of your router, because that really depends on the brand and/or the ISP. Some ISPs even manage theese things for you so you have to ask them/login to a centralized system to control that stuff.
i'm trying to find that in the router's 141 manual pages since yesterday. I might as well contact the ISP
i might have found some bridge things but i'm not 100%sure those are the correct settings to look at
What model/brand is it?
D Link DVA-5582 . i could send you the manual but it's in italian
You could use the Pure Bridge function.
But like it says it will disable all management functions so you have to be ready with all the other configuration.
"Pure Bridge mode disables the local DHCP server, causing your ISP to assign IP
addresses directly to any affected bridges. By default, the assigned bridge is all
Ethernet and Wi-Fi LAN clients." maybe i didn't understand correctly what that does but, isn't that going to assign a public ip to a bridge?
Yes, is not that what you want with bridge mode?
In theory the router/modem will become a modem.
and the next connected device should get your public ip
Indeed.
i can set an option at my isps homepage to get my modem into the bridge mode
doesn't it takes that public ip and "transforms" it into 1 private ip where i can hook up my router?
No, that is only acomplished with a router with NAT and firewall functions.
And would over-complicate your setup hugely.
so my new router would need a WAN port with dhcp enabled so that the isp can give the ip right?
not neccessarily
for pure routing functions normal ethernet port can be enough
but thats up to the router
Well, lets just be perfectly clear
Ethernet ports and WAN ports are the exact same thing.
yeah i mean that will be used to "connect to the isp"
The only diffrence is that a WAN port is by its definition and confiuration set up to be against the outside of the network (Wide Area Netwok / Local Area Network).
But yeah. You have a EdgeRouter? I think the default config on that one is eth0 for WAN.
So connect a cable from the ISP modem to eth0 and when bridged and the EdgeRouter is configured correct it should work just fine.
for now Eth0 is used to access the router. Any other ports wont work
like the untrusted zone
You will probably have to configure ports for LAN and WAN then. I think there is a way to apply a default config with a wizard that could help you on your way.
ill see what i can find. Thanks for the help guys
Oh and remember, the ERPoe-5 does not have switching ports. This means that you can only route, and that the LAN port needs an external switch if you want more than 1 device connected (which you probably do want.. π )
it will be connected to a 48 port switch π
so different LAN ports can't talk to each other?
Yes they can talk to eachother, but only with routing. meaning that they will be on diffrent networks (10.0.0.0/24 on eth2, 10.0.1.0/24 on eth3)
oh ok
So this sounds a little bit weird:
I am having a asus rt-ac68u router with asuswrt-merlin firmware installed. And somthing strange happened 2 months ago.
One day i found that i cant connect to baidu. (The baidu.com domain works, but some CDN domain like tb1.bdstatic.com wont work with connection time out)
And i swapped the routers, and it works again, but due to the slow speed of the old router, i changed back to ac68u, and it works again.
And a few days ago, it went down again, and affect more chinese website.
Anyone know why this happens and how to fix?
PS: google and most western websites works, and i use those website for a reason.
Do you know if it is a DNS issue? Maybe try checking with "nslookup" tool in command-line.
So it is a DNS issue?
idk, i am using 1.1.1.1 and 1.0.0.1
On your computer directly yes? Not through the DNS relay on the router?
Try this:
Open CMD
nslookup (this enters the nslookup command line)
tb1.bdstatic.com
Wait to see if you get reply
server 1.1.1.1
tb1.bdstatic.com
Wait to see if you get reply
If the reply is the same then there might be another issue.
Look at the IPv4 propagation map of the YouTube ASN
There is a good reason for it to look like this. It's because usually people peer with Google's normal ASN to get to youtube so this ASN is only used in places where Google's normal services are not available which causes the map to be weird. The map for google's normal ASN is a lot simpler
this is a bad dns record on the pc not the router. do a ipconfig /flushdns than a ipconfig /release than ipconfig /renew
than reboot both pc and router
is google fiber still laying down fiber?
In some places, yes
i was hoping to see them coming to italy π
I wouldn't hold my breath :P
They've pretty much stopped in most places
Most of what they are doing is finishing out their original commitments and that's about it
yeah. Now i don't even care. Open fiber is laying down fiber everywhere in Italy even here in this city
nice
i bet in few years 1 gbps will be obsolete
I doubt it
I would say 60% of home devices don't need more than 100Mbps and those that need more still don't saturate gigabit links
maybe not in few years
I'm sure maybe 10 to 20 years down the road most things will be wireless or moved to mgig at least
or maybe ISP's will offer 10 gbps at a reasonable price ?
Hey now, don't make me laugh so hard π
here we dont even have ISP's that give 10 gbps hehehe
AT&T is supposed to offer 5Gbps and 10Gbps for home users in the next few years but I doubt it will be at a reasonable price
π¬
The tech I spoke to said that 5Gbps is maybe going to drop in the next year or so
at 1000$/month
Probably $150/month but that's just speculation
- the price of the router i would say
I hope they let me use my own at that point
no more bridge mode with their modems
At least let me request more than a /64 for IPv6 =/
and give me a static ip
i mean if they say that IPv6 range will never be saturated any time soon, why don't they just give everyone a static IPv6
i think my isp is still using IPv4
Because that requires thinking to implement
Spectrum would bind your IPv4 address to the MAC of the router behind the modem so it was basically static unless you went offline for like a week. For IPv6 they would give you a new block if you so much as blipped the interface -.-
do you have an IPv6 ?
Not right now, I've not bothered with it
AT&T decided that you only get blocks of /64 addresses with their latest "modem" box for fiber and you can't request anything larger like a /60 so if you have multiple VLANs then you're screwed since you need to figure out how to request multiple blocks on the connected router and deal with routing traffic from each VLAN out a different interface which is near impossible
i didn't completely understand that but it doesn't seems something good
Basically you need to have an interface connected to the modem for each /64 you want but because you can't just say "all non-local traffic goes out interface X" since you'll have that traffic come back in on a different interface, you're SOL
ask cisco to become an isp provider with all the features that are missing with others isp's
That would be bad for business π
why?
Why would an ISP buy from Cisco when they are also the competition?
netflix is a competitor to amazon but they still rent amazon servers
It all depends on what options are out there. If you have a large choice and suddenly the person you're buying something from becomes a big competitor, why would you continue to give them money while they steal your business
Netflix and Amazon aren't direct competitors, sure Amazon has a service that competes with Netflix but it's not their main product
that's right :/
I need help every time I try to connect to my WiFi or go online my whole WiFi disconnects
Should I get 4x gigabit NIC for my server or 1x 10gbps SFP+ nic?
@thick minnow what do you mean? Does your AP wireless signal turns off?
@remote kernel i think it depends if the 4x1 gig NIC has link aggregation
@subtle glen whatβs ap?
the thing that gives WiFi
"I need help every time I try to connect to my WiFi or go online my whole WiFi disconnects"
Yea
i have troubles understanding. The Computer is connected to the router using a ethernet cable?
what do you mean by almost
Ethernet is a technology that a LAN can be cabled with
Yeah
they are not the same
Exactly. So even if it's over fibre channel or Ethernet or god forbid DSL it's still over LAN
how can we help you
@remote kernel for the NIC, depends on whatβs going to be on the other side. In my situation a 10G NIC would be what I would get but if you donβt have anything to connect it to on the other side then itβs useless
I'm getting a 10G switch
Does anyone actually have 10 Gigabit internet
Usually not about 10Gig internet, it's about local transfers and sustainability over 1Gbit without LAG
There are a few places in the US that offer 10Gig but they are usually small towns with their own ISP
I don't know about only small towns having 10gb, UTOPIA services 11 or so cities in Utah, I have 10gb service
Interesting, I only know of a couple places that have it and they aren't very large cities or anything but good to know
I wish I had 10G. I have 300/20 at home and about 3G transit total for my ASN
having 10g service is one thing, getting 10gb speeds is another thing, but as ISP upgrade it will come along, just like 1g server used to be when it first started hitting the public
Yea
They often oversubscribe
Or technically have 10G but not 10G to any specific place, more of an aggregate
mmmm i want to become an isp then so that i can have 10g
10G transit is quite expensive though
I guess if you hosted your own Speedtest server then you could put a 10G card in it. I may try that
doesn't Linus have 10g?
I donβt think so. I think itβs more than 1G though
Iβll have to check on what it was
Just checked, itβs 5.5G
https://twitter.com/linustech/status/1034878527168897026?s=21
Just upgraded our Internet service at the office to 5.5Gbit... https://t.co/Jc5KN3hglx

@fresh copper I swear I didn't install my own speed test server no sir not me
Iβm going to make one at some point. Maybe make it on a different VM on the same machine and see what the max inter-VM speed I can get is
you could always use Ipref
Thatβs not as fun
on a vm with those 400 gbps NIC's Lurick mentioned
hello guys!
am I alone to have this bug in ESXi 6.5?
ESXi see that my CpU can go up to 11.1 Ghz
but I got only a small I5 2300 CPU
okay... to my mid this is quite a dumb way of watching CPU usage but... why not
Well ESXi "pools" resources together so it's their way of showing you total CPU power
@subtle glen Just FYI there aren't any 400Gbit PCIe NICs on the market, I doubt they will show up for a year or two at least. They are probably coming but not for a while π
I use fast ethernet, it'really slow too but... I don't have the choice
BTW thx @clear igloo :)
@sturdy mirage i have no choice too. Wifi arrives only if i put an ap on the balcony and if i leave the garage door open (or i could drill a hole and stick the antenna out. Now i'm seriously considering to run a fiber cable and use 2 media converters on each end so that i can have at least a 1 gbps speed
I just sent my stuff off to be coloed! I'm sending it to a friend who is doing down to the DC in one week by car so that I don't have to ship it all the way.
I have a Netgear gs724tv4 24 port managed switch (with a single single mode fiber 1G sfp in it), an Edgerouter X, and an Xserve 2008.
I have 4x1G LACP from the Xserve to the switch. I also have all the ports of the edgerouter connected to the switch but they each have different VLANs on them
Nice, better uptime and service hosting?
Yea, faster internet speeds, static addressing, not having to listen to the loud fans, couple people to peer with.
@chrome hound gonna need me a better speedtest node, https://dooleylabs.com/?q=hzhttn.png
Btw, nice IP, but maybe don't share it with the world
69
i see a challenge here
Nope, just two people maxxing out speedtest nodes.
My machines were 30Gb/s, so Β―_(γ)_/Β― and they were in a datacenter. They were not my own.
mines have a 100g NIC, they saturated the node so it shows 7/0.6 mbps
absolutely not my connection
π
two gigs, one bottleneck
they are in 2 different buildings π
funny thing about public IP's, they are public

I wonder if Qwest knew that 69 would be come a thing when they were making that request for IP space back in the day
@unreal wedge century Link ooof
I could be wrong, but I think that space was taking over by Century link when they bough Qwest, but I could be wrong
The number has always been a thing.
lol well maybe in 2003 I just wasn't aware of it being a thing π
AT&T, why you suck at IPv6 still ;-;
Wish I could just buy a block of address space easily too =/
wish i could have 2 fiber lines
Regarding public IP's, can you still do that bridge mode thing to use your router even tho the public ip is dynamic?
You mean pass the IP to the box behind the ISP's box?
yeah, use the modem/router only as a modem and use the edgerouter as router
cause i was looking at the interface option on the ubiquiti router and there was "assign ip manually/ use dhcp" and i thought that the dhcp was to assign ip to a device connected to that port, not to receive an ip from the isp
that's why i was wondering if it would still work even with a dynamic ip
DHCP is to receive a dynamic address from the ISP and can also be used, in server mode, to give out IP addresses
oh cool, so i just have to set (in this case) Eth0 with the DHCP server enabled. Now i just have to figure out how to put the modem/router in bridge mode π
@subtle glen got your new router working?
Yay
@clear igloo there is a "pure Bridge" thing at page 25 or something but i cant understand how to set it up
@rocky badge you have an edgerouter too right?
Yea
cool
Hi
That feel when you have everything on PoE power and free up a whole power strip π
did you switch everything on PoE?
Anything with a barrel plug or micro usb port and ethernet port, yes
now you have a box of poe injectors
nope, all off a PoE switch π
ohhh thought you changed from injectors to the switch. Now i saw the message
AH! No, I changed from wall warts to PoE power
were those ap power supplies and stuff like that?
No, random IoT devices
APs have always been on PoE
Got a bunch of these and some 1.35mm barrel to 2.1mm and 2.5mm adapters
https://smile.amazon.com/gp/product/B019BLMWY0/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1
can the switch automatically switch between 48 or 24 volts for the different devices?
ahh i saw them on amazon too
Everything I've got is all 48 volts input iirc
Since 24v is non-standard I don't think it does but I could be wrong
i remember something about the switch that had PoE 24/48 v but i'm not sure too
I'm sure some exist, I just haven't seen them π
Yah
if you access the switch and do 'show inventory' it will give you the full model number but 'show plat' is usually cleaner
there wouldn't even be a good use for it
no good use for what?
poe over sfp
Oh, yah
It would be out of spec with regards to temp and harder to cool the SFP as well
do you recommend an ip range in particular?
for like what DA SFP cables?
lol for some reason I was thinking fiber SFP and was wow that would be cool to power my device from a couple miles away π
That would be awesome
Yah
like having fiber traces on mobo's: no heat,more efficient, less copper used
I wish I had the picture of the 400Gb switch handy with all 36 or 32 ports cabled up while showing the insides but I don't feel like opening up my work laptop π
Prototype, yah
this is getting interesting
rumors about the price?
I can't say even if there were
I can't even make a good guess at this point but around the 40K to 50K mark for the list price wouldn't surprise me
what if you have one of those cards that have 2 qspf (or whatever the 400gb is called) plugs: can you link aggregate them?
I don't see why not if the card supports it
Would only help if you had multiple clients hitting that box though
So if you have a quad sfp+ card you could link aggregate the ports, right?
Depending on the card with SFP+ you either get 4x10 or 4x25 ports but yah, not sure of any card that wouldn't support some form of aggregation at that level
whats the back plan on a 400gb switch like speed wise?
because you know: i have to saturate that 2,5 hdd connected to the usb port of the router speed. Maybe we are close to saturate it with that quad sfp+ card
lol
lol
but wait. If the 400 gbps switch is still a prototype, what does an exchange point or a submarine cable land station use?
at my work they are working to upgrade core hardware, they had a lot of demo hard ware in, the challenge is space for us, most hi capacity/speed switches are full sized, when your cabinet only had 18 inch depth it makes it hard
fiber is fiber is fiber
most places use a bunch of 100Gb aggregation right now
Yah, cabinet density and depth can be a challenge with a deep switch =/
the Fiber to my house was installed when the max speed was 100mb with out replacing any fiber they can push 10gb, and to go 100gb on the same fiber, you just need a second fiber
those switches are really long, i cant fully open my door cause of that
So long as the fiber is SM then you can swap from 100Gb to 400Gb pretty easily but nothing I've seen mentions multimode transceivers yet
well multi mode is pretty short range so
Yah, lot of data centers do MM for the short hops but SM for the backhaul so it shouldn't be an issue in most cases but there is always that one place that uses MM everywhere xD
typically if you are that close to the device your stacking with copper stack cables π
what if you want to increase the speed over a fiber line: do you just have to change the "machines" in the cabinet? or they just "unlock more speed" cause these "machines" are capable of higher speeds
its mainly optics to a point
Yah, optics and whatever it's plugged into
but we have a lot of older Omni switches that max out at 1 gig
which for typical res deployment all you need, but there uplink ports are only 10gb so after you get to a point of load you have to have a switch with 100gb uplink or you create a bottleneck
I still donβt see the benefit for MM even at short distances. As far as I am aware, with the current technologies they both support the same speeds. I have heard multiple arguments as to which one is less expensive.
MM is must lower on power usage
much cheaper optics
for example the MM I use in my house cost 15 bucks per, versa 80 for LR optics
there is also issues with burn out, the LR are laser so your running the risk of burning something in short runs
tf
LR is great for eye surgery though, just a quick zap of the optic and you're good to asdflkjasdl;k;lweqrjlklalllkafjlksadfjlkasdfl
MM Optics are after all LCD
hehehehe
just wow a pin point laser joke...
I will say, the one thing about MM I don't like is for the higher speeds you usually have to deal with MPO cables over standard 2 strand cables
passive is not the light but how the hardware talks
then i guess it's not good for your eyes xD
nope
few months ago i thought you could see like a red dot of light pulsing if you look inside that cable
now i know its something like infrared you cant see with the naked eye
well its wave length for sure, we deal with active Bidi optics so we are pushing both directions in the same fiber on different wave lengths
i didnt know you could go both directions
https://www.fs.com/products/12735.html this is the one I have in my ONT that bring my connection in
Check FS Compatible 10GBASE-BX SFP+ Transceiver module data sheet (SMF, 1270nm-TX/1330nm-RX, 40km, LC connector) and price list on FS.COM, buy it now!
err might be the 60km because they have to re-route my fiber to a hut that had proper 10gb ports
new card comes in Tuesday, but I forgot to order optics so I have hoping the Chelso will accept intel optics, we will see π
i should have this connector if i get fiber
ah, nice. Hope it fixes it
me too, al though my CEO found my speed test server π
lo, whoops π
busted
@chrome hound lol
and was all who the hell is running a speed test server in orem and how has that kind of speed that is not on our network, the Head ENG guy was all, ooohh thats just your Web Developer
was he like "hahahahaah how funny.............. you're fired."
lol he was pretty impressed, just cough off guard was getting nervous about some new internet provider
quickly deletes the server
@clear igloo Things you do to bypass Verizon hotspot throttle
for that speedtest server, do you just make the procedure to become a speedtest host and then open the program on a pc and select your server?
there is a bottle neck across our NNI we have 2 10gb bonded ports handling two sides of the network
"bottleneck"
@subtle glen https://support.speedtest.net/hc/en-us/articles/203845650-How-can-I-host-a-server-on-Speedtest-net-
yea you just stand it up and then they will approve it or not
then you can search for your sever
but other people can use it for their tests
Yeah
isn't that a "network safety hazard"
No?
what people don't realize if your speed tests will only go as fast as the fastest router in your path and the available bandwitdh
well it could be, but you need to set it up correctly, I have mine out side of my internal servers and even if some one hacked it, I just turn it off and rebuild it
like when in a film they hack fbi and they just reboot
what about turning off and on the power bar
:/
are those batteries?
wtf do you have to power when there is an outage, your entire house??
for 2 days?
like I said if her internet goes down I am screwed
I am short batteris to run for two days π
its an over time project, I buy 16 at a time every 6 months
lol i have a cheap 600 VA ups modified with 2+ batteries (so 3 in total) that powers routers, a switch, my pc and a plex pc (that i never turn on)
if i turn on the pfsense pc/my pc/ the switches and router, the ups goes into overload mode
My real goal is to keep my NetApp from powering down, in the event of a power outage I can SSH home and shut things down gracyfully
well, those are a lot of batteries, cant they power everything up?
oh yea
"for 1 day only"
those are 30 amp draw UPS's
well keep in mind I only have 1 battery sled per chain right now
and that one sled will power the stack for about 2 hours
well 2 sleds but still
if there is a power outage build a male to male cable, turn off the main breaker, plug the cable into a random plug and into the ups. You can power your house
whats that empty switch
a cisco 3750? I think
I replaced it with a netextrem when I wen 10gb through out the house
funny thing is I still have like 8 devices that have to have a 1 gig cooper port, suck as my AP
do they make those?
