So I wanna be in AP mode?
yes, to avoid double - NAT
But I'm still confused why it's limited to 100/100
yeah I'm looking it up right now
It should be something around 1000/600. I tested it
Thanks, I'll try and figure it out as well in the meantime
Go to Basic->Network Map->click on the Icon for TP-Link router.
should see something like this
It is saying 100Mbps Full Duplex. What
The same cable gave me 1000/600 when I tested it from isp router > laptop though
Same exact cable
it could be possible that the port on the router is damaged
maybe look into it and make sure there are no obvious damages?
I remembered getting like 300/something before my plan change
yeah but that has nothing to do with it
you tested a computer on ethernet on the same port on the ISP router?
So I switched cable and it now detects it as 1000 Mbps Full Duplex. Getting the speed I should be getting now
And yes
nice
This is very weird
could have not been plugged in all the way
But hey thanks for helping
np
Maybe. Was operating with one hand. The other arm was holding my laptop
Btw @peak cloak is it okay to leave it as wireless router mode? I don't know how to access its default gateway with AP mode. Seemed to be the same ip as isp's
it should be fine but it's good to avoid it as it can cause issue
to find the IP just go into your ISP's router dhcp page or they may be called something like clients
and the AP should come up
ah I see. Thanks
another question. Should I enable OFDMA?
sure why not, it's a new thing in wifi 6 that helps with congestion
I read some articles/forums and some said it can create some issues with older devices and such. Don't really know
Also, I've been quite curious for a while. Does it hurt to leave both Channel Width and Channel on Auto?
or should I specify them?
the channels I can pick and the ones in the area are all collided pretty much
but the fewer networks in the same channel, the better, right?
yes
I see. Also, if I wanna improve the wifi speed on my second floor, will powerline adapters work? I've been looking for something that can maybe improve my experience on the second floor
sometimes
powerline is iffy
ethernet is the best
1 gigabit on lan, 600-ish on wifi near the router, dropped to around 30Mbps in my room (from what I tested so far)
parents don't wanna drill any holes in the wall/floor so ethernet is probably impossible at this point
it's a bit hard to route the cable as well. The router is on top of the shelf, in the middle of the living room so yeah
I know people at LTT love their networking so I thought I'd ask here, is this a good way or a bad way to get a NAS going https://github.com/davestephens/ansible-nas
Content: I bought a pretty low-power workstation to do something with, that didn't work out and I couldn't return it so I thought I'd turn it into a home server sort of thing. I set it up with Ubuntu server. The NAS part is running with samba but it always feels like it's only just hanging on, and sometimes (like just now, which is prompting this investigation), it just stops working, so I'm looking for other solutions. I don't really want a dedicated NAS OS like FreeNAS because I run non-NAS things on the server as well from time to time, but NAS is the primary purpose. I would also prefer not to change OS as I already have a lot of files already transferred on there.
from 600/600 speed (on wifi) on the first floor 
that's just an ansible playbook to get a nas started
it helps to actually understand what it's installing and stuff
depends
Right...
it seems to be quite faster than what I tested though. Is this normal? or am I out of my mind
how many drives
My only requirement is it works with all OSes because I have Windows Macs and Linux computers to use it with
I think it has space for two or three drives
filesystem is what it's actually stored on, the actual share is seperate
ZFS for 2-3 drives though is kinda useless though
you need at least 5 drives for radiz2
I don't think RAID is really good for the scale that I'm doing
yeah
I probably don't even have 3TB of stuff to store in there
just keep in mind that if a drive fails, that it
sheesh it's actually averaging at 50/50 wth
on ubuntu you could setup an LVM
I'll be sure to make regular backups to somewhere or other. I think you get warned if drives are starting to go, though?
yeah kinda, smart should start giving warnings, although not all the time
Yeah
Could always get two drives and mirror and then if one drive fails then you can recover the other
But moving on
yeah but you loose 50% of capactiy
Once again, true
ZFS has that option, but it's not great to loose 50% of capacity
Most of the stuff is backed up elsewhere (in the cloud etc.) and the NAS is just there for convenience so I don't think redundancy is too much of an issue at the moment at least
I mean is just going with good ol' Exfat a terrible idea?
if you have a single drive, and not using raid, any journalling filesystem will work
if you have two drives, and want a simple raid volume, just use btrfs raid1
ZFS is for scaling into large systems
if youre fully comfortable with the prospect of rebuilding a failed local array from a backup, then you can basically do whatever you want
like raid 0 go for it
splitting the data across multiple disks, with no parity
meaning that if one disk fails or becomes corrupted, the entire array is gone
if you are like "cool ill just make an empty array again and restore my data from backup" then thats fine
I'd probably do that
Although given how little data I have, the drive mirroring thing might be good at this stage too
raid 0 is referred to as striping, or a stripe set
raid 0 is also a lot faster
mirroring means all the data exists on two disks, so one disk can die and your array remains intact
yeah raid 0/striping gives the best performance, mirroring cuts capacity in half and gives good read performance but no boost to write performance
so if youre good with rebuilding and this is pure convenience then striping is probably the best
What if you had one RAID0 drive and one drive that was mirroring the RAID one?
RAID 10 sounds like it would be a good idea if I can find the drives to support it
its a raid 0 stripe array, except the elements of the array arent disks, they are pairs of disks
so while its still a stripe, its very hard for that stripe set to fail, because each element is a mirrored disk
you get 50% usable capacity with that configuration, same as raid 1
That sounds ideal
four disks that are 4tb each, will give you 8tb total out of the 16 raw
I probably have 4TB absolute maximum of stuff I could put on there
im just picking numbers to illustrate
Yes
a raid 0 using those disks would give you all 16tb
OK
Is there anywhere where I can read up on all the different RAID types?
yeah im not gonna be that asshole that says just google it, but you can
ill pick a few links for you to make it easy
Thank you
I know I could probably Google it, but I find that people usually have special recommendations which are better than the first Google result
i dont have any on hand but ill look through the google results i get to see which are better
Thank you
Next question is, what software does one use?
FreeNAS would probably be the easiest but it wouldn't be ideal because I'd like to use it for non-NAS tasks as well from time to time. Ideally I'd have something that runs on top of Ubuntu server because I already have that installed and mostly configured
honestly i dont love any of these lol
What's your recommendation?
basically all you need to understand is a few basic concepts: mirroring, striping, distributed and non-distributed parity, and nesting
mirroring just means everything that is written to one disk, is written another, no matter what, this allows double-speed reads and normal-speed writes
striping is splitting each individual chunk of data in parts, and distributing those among multiple disks, which allows for faster reads and writes
Read speed is good for me because I'd mostly do reading, but I think I'm currently bottlenecked by my network setup which I can't really change
parity is a calculation done on the data that allows its verification and reconstruction, parity data is either distributed amongst the storage disks, or located on a dedicated parity disk
parity allows any one disk to be rebuilt if lost, double and triple parity allow 2 or 3 disks in a group to be lost
a distributed parity array with 4 disks will use 1/4 of each disk for parity data, and 3/4 for storage
a non-distributed parity array with 4 disks will use one entire disk for parity data, and 3 disks for storage
nesting is the combination of any of these methods, and is seen with the two-digit raid designations, such as 0+1, 10, 50, and 60
they should be read as "a in b", so raid 10 is "raid 1 in 0", meaning it is a set of raid 1 mirrored elements, that are arranged in a stripe set together
same for 50 and 60, which are single- and double-distributed parity elements, arranged in a stripe set
the raid designations you will see in use, in total, without the little fringe exceptions, is: 0, 1, 0+1, 10, 5, 6, 50, 60
so thats a stripe set, a mirror set, stripe-in-mirror, mirror-in-stripe, single distributed parity, double distributed parity, single distributed parity in stripe, and double distributed parity in stripe, respectively
parity calculations take a lot of cpu, and thats where performance hits come in, and where hardware raid controllers become relevant
Interesting
yeah thats basically raid in a nutshell
But unless I missed something, this still doesn't answer the original question of "what's the best software to use in terms of broadcasting the contents of the drive to computers on the network"
you can go as simple as windows file share
you can set up a bare metal or virtual truenas machine
Currently I tried using Samba but it hasn't been very reliable, probably my bad on that one
If I switched, I'd want something that was a little more intuitive to configure
truenas is pretty dead simple but like, installing windows and creating a file share is also pretty simple
in terms of managing the storage hardware thats another story
freenas is ZFS
and has samba
Ah, but if it had Samba it would have a way to configure it that I would understand better
we should stop saying freenas and start saying truenas
otherwise people will be confused
there is no longer a product called freenas
its the same thing, theyre just rebranding and repositioning their product lines
truenas core is the product that was previously freenas
I think the best thing would be something to go on top of Ubuntu Server though, as I already have Ubuntu Server setup, am somewhat familiar with the Unix terminal (as opposed to Windows cmd) and it would also mean not having to erase the files I've already transferred and start again
you can install truenas core as a virtual machine inside a KVM virtual guest
That might be an option
And if it was in a VM, could it access the files already on the current Ubuntu server setup?
the vm would be have as an IP network peer, except the medium that the IP network is running over is virtual and internal
if you pulled the files into the vm storage over the virtual network connection it would be at hardware speeds basically
So I would have to transfer the files, but it would be quick?
you'll want to talk to people with stronger opinions about how to set up truenas than me for more specific direction on that
yes
it would be quick
idk if you have to
it's complicated
I would've thought I could just point the VM and say "Hey, this is your filesystem now" and TrueNAS would pick that up
you may be able to separate out your storage disks, feed them directly to the vm
is ubuntu on one drive?
@peak cloak can help you with the best way to use truenas
idk much about truenas tbh
used it once
just for experimenting
now I have a bunch of extra drives so I may set one up
if you pass entire storage disks to the truenas virtual machine in KVM that is probably the cleanest way to do it
the hardware devices
then just dump all the data into that, over the internal virtual lan
OK
@rare matrix that's what I do, except I run LUKS on the host
and then I just mount that filesystem into the virtual machine
solid
I've been reading about Ubiquiti's UFiber equipment and I'm confused as hell.
I know no multi-ten million dollar fiber company who owns their own lines would use this sort of equipment for their services.
If it's not intended to be sold to them, then who is this product marketed toward?
It's listed under UI's "ISP" section, but from what I know few companies have access to fiber besides the big players.
My local ISP uses UFiber
Dark Fiber
and Adtran Total Access
they don't have to lay fiber to use it
what about last mile fiber?
you still have to pay thousands for each home for that
Are they a large company?
No
I wouldn't call it thousands for each home
How are they able to afford fiber lines then?
Dark fiber exists, yeah, but what about to each home? Not every home is right next to a fiber line.
The electric coop here runs the fiber and maintains the fiber. They then contract out with this company to provide Internet
The company they contract out to is local, they handle equipment, FCC, FTC, legal, licensing, support, etc
Alright, so the electric company builds out fiber to homes and then licensed it to them?
Yes
What about in situations where that's not the case?
Since the electric company already owns the poles/space
How do you get from dark fiber to home?
They don't offer services there then
They only partnered to provide Internet to their service area
So this is sort of a niche product for areas that fall into that category?
This coop is the only electric provider in the area
No, I meant that it seems the UFiber product line is really only applicable in situations like your area.
Yeah, small ISPs
I don't imagine some large multi-coast provider using it.
yeah no, they have their own custom solutions
yeah
No, those are using alcatel lucent, Huawei, Nokia, Calix, Adtran
well yeah
, cisco
Rarely seen Cisco GPON
Not good?
Your fiber situation isn't the same as mine, is the way your electric company does it common?
idk
there is also municpal fiber
Only real fiber in my area is this fiber that goes along my cable lines but doesn't terminate to any houses
I don't know what Xfinity is using for their fiber only
Xfinity is doing fiber for brand new areas
With no cable in place already
Yeah, I have Gigabit Pro 2gbps down/up available in my area and Gigabit cable already.
We just have to pay a thousand or two upfront then hundreds each month.
Not worth it
optimum now offers fiber in my area
apparently the router they give is also the ONT and there is no way to bridge it
Verizon FiOS is Alcatel Lucent iirc
yeah
Frontier's looks similar
FiOS isn't that good from what I've heard.
better than optimum
wonder if you could reverse engineer the fios GPON auth to use something like this https://mikrotik.com/product/SFPONU#fndtn-downloads
but for me it's not needed
with optimum I would really try to bypass their gateway
gigabit pro atm is metro fiber
they just give you the whole thing and don't segment it because there's not enough customers for it lol
wdym by whole thing?
idrk
watched a youtube video on it
they rent to you a whole juniper $10k switch
@peak cloak the sfp module wouldn't control it
yeah ik
Yeah, gig pro is their business service provided to home
Essentially, yeah
2gig/2gig via fiber, gig/gig over RJ45 ethernet handoff
you would have to reverse engineer it and configure it on the router itself somehow
this is what it is
A metropolitan-area Ethernet, Ethernet MAN, or metro Ethernet network is a metropolitan area network (MAN) that is based on Ethernet standards. It is commonly used to connect subscribers to a larger service network or the Internet. Businesses can also use metropolitan-area Ethernet to connect their own offices to each other.An Ethernet interface...
basically you're not sharing the fiber with anyone else from what i've read in the articles
Metro-e is for L2VPNs, Active-e (AE) is for direct fiber. We have 50/50 GPON/AE
Ah, yeah, read up on it.
It's like metro-e, but it's actually not.
They just supposedly give gigabit pro providers priority in the network.
GPON -> 1-to-many via splices
AE -> 1-to-1 direct
Metro-e is using QinQ and VLAN translations, typically no internet services provided
direct L2 circuits between sites
Depends as there is many ways, we use QinQ/translations (metro-e), VPLS and VPWS depending on the setup
What's your field?
Engineer for an ISP
L2VPNs are still sadly very common with metro-e being the worst of the bunch but pretty much required for all L2VPNs in an ISPs network
maybe you can help me figure out how practical something is, then
Sure, ask away
friend lives in the middle of nowhere in georgia, small town with like shitty dsl
right up against where the houses stop, theres a large industrial complex, where southern fibernet has a facility
how practical is it to get them to consider trying out carrier-grade fixed-point wireless
covering the entire tiny town could be achieved from that single facility without much equipment
WISPs are common and growing in many places. It really depends on the size of the town but Mikrotik's line of AP connected via a wireless link can easily reach a few miles to the stations. Mikrotik is pretty much standard in WISP. Not enough experience with stability though
Not really. They do have an entire line but almost all WISP in my state is all tik
the equipment isn't really the issue though
like we know it's practical, WISP is a working model
I just want to know how to approach it with them
If its something you want to try you will need to reach out to the city for permits, once approved then you can contact the owner of the facility on peerings and cost.
so this is a process driven by the municipality
like I'm asking southern fibernet to try out a new business basically, in this tiny market
I'm not trying to start an ISP
Partially. You cannot go flinging RF around even if its approved wavelengths. If you are providing service at all you will fall under an ISP and its regulations
ok so regulations aside
I want this company to invest in this setup, and to sell service to these potential customers, none of whom are me
this is a friend asking me to be his IT executive for his own business he runs from home
so I'm calling this ISP as a tech executive for a local business that wants to buy fixed point wireless access from them
what's my in, what's my selling point, who do I ask to speak to
Ah gotcha
You can just reach out to them and talk about the cost of setup for a business customer. There is not much of an "in", but lead with "how much would it cost for a wireless P2P" not "can you provide a wireless P2P". Tends to always be the best way to approach sales.
yeah, i definitely priced out the equipment ahead of time so i know vaguely what im asking them to invest
and i counted the households who are potential customers
id be trying to sell this as an exploratory/alpha test service
Make sure you bring it up to them about multiple customers being fed off this and a peering.
If the ISP gets hit with a DMCA or the FBI reaches out about a customer behind that AP, you are now responsible
i mean, theyre already an ISP
this is just a different style of last-mile
theyve got residential customers elsewhere
Its still a connection you are in charge of. I will guarantee they will not handover the last mile services, your peering would be the same as a customer's.
i dont want any of that
i want this ISP to offer new service
"hey we sell fixed point wireless now"
"lucky we had a site right next to this town"
i dont want to run a facility or a network or anything
i want to get this company to buy radios and sell my friend internet as an end-user
If you are just trying to get them to start selling wireless, you are going to be hung up on. Typically if you approach request like to any ISP you need to go in with cost, customers, businesses, contracts, etc.
I get that, but this is a cost to them as well
"please service this customer base, here are estimates"
obviously there are costs
this isnt a charitable request
its a business case
"you guys should sell this here, look who is willing to buy, this is what it will cost in equipment"
It is but we get these scale of request all the time, its not worth it unless there is clear profits and estimates for min of 5 years
so show 5 years of estimates and show profitability?
That would be your best bet
They have to take in training on new equipment, support, hardware licenses, contracts, SLAs, provisioning, redundancy, E911... If it fails they are now at a loss, damaged reputation, possible fines. ISPs are far from cheap and a little risk can turn out to be disastrous
😷
so not selling crap is important, check
who needs to be the one on the other end of the phone to hear this request
im familiar with all these concepts already, i dont work in ISP systems but ive been in SMB and enterprise tech for over 25 years so we dont need to cover all that
getting an ISP to service a new area is something i happen to not have had to do before, despite being around the tech block many times by now
Im just bringing up theres more than what enterprises have to take into account. If you want to really try then reach out to marketing first, then sales. If its a smaller or regional ISP then you can even try the VP

🤔 So are we still using flash at all, or did it all migrate over to HTML5?
The flash player I meant
Flash is dead. Long live the king.
🤔 Ok, well, I asked because I'm having a minor issue with my connection, quite silly actually. When I try and post an emoji on certain websites like YouTube or Linus Tech Tips, literally my entire internet connection grinds to a halt for almost five minutes. It goes back to normal afterward and then I can post as many as I want. I can't figure that shit out. 😆...It seems to work fine in Microsoft Edge. Its very specific to Chrome.
Is chrome up to date?
I think, let me check.
@thorny vector 🤔 Well, I don't see a button for an update, so I'm assuming its current.
Weird edge works, but chrome is buggy, considering edge is basically chrome on the backend.
Yeah, it says its up to date I see, so I have no idea what the issue could be. I guess I'll just report the issue through the settings and see what happens. 🤷♂️
Is it your whole internet at home or just that computer?
Just mines, and only through Chrome it seems. 🤣 Emoji fucking the entire internet up. I'm betting someone makes a movie out of it.
I bet it's not internet but just computer
Like, I can post emoji's just fine on Discord, its mainly sites like Youtube and the Linus website where this occurs. 🙃
You could check what's actually happening in your network interface with something like wireshark. Although try uninstalling and reinstalling chrome?
I'm actually looking at Wireshark now, but I have no idea what I should be looking for though. I guess I can try reinstalling Chrome.
There is this protocol that keeps popping up called "STUN". It apparently has to do with VOIP. I have a headset connected, but I'm not actually using it right now.🤔
Disabled Googles experimental "QUIC" protocol to see if it works and went back to TCP. It didn't fix it.
unreal dev kit
oh
@little schooner hi
@thorny vector 🤔 Well, in Wireshark I noticed a constant duplicate TCP retransmission to this certain IP address. Nslookup claims its a non-existent domain, yet it has no problem pinging it. 🙃 WTF.
Is DOCSIS proprietary to Comcast?
No
It's a standard
How come I don’t see too many companies offering cable service compared to the amount offering fiber?
Not sure if I brought this up already, but the lines are leased to specific companies only, if I’m not mistaken?
@waxen scroll hello
What do you mean real? Is there a reason why you believe its not? 🙃
is it real IP or shared IP ?
😆 Well, is what a shared IP? I have no idea what you are referring to. Just type 'IPconfig' in the command prompt window and see what it says.
Maybe he's referring to a single assigned IP or one behind a doubleNAT or CG NAT or something
ew
@tall pagoda lol mikrotik cAP ac's cost 60 bucks each
and you can group them together into a single network
tplink is 
big oof
I have those, they are nice
ubiquitu....
😂
ouch
The biggest failure is exposing the VMware administration to the Internet. 15,000 sys admins made this mistake?? That’s scary.
@waxen saddle its not that surprising
when you rent a dedicated server with vmware
you just get a public esx endpoint
You're probably right.
I have bought for 56 euros a piece, now it is 69 euros
That vmware thing has been pestering me for 3 days in a row, my vcsa refuses to properly update, it always gets stuck 
@desert briar do you know the scope of affected systems?
I have a singular ESXi instance running
I'm not using vCenter
just vSphere
@desert briar I actually don't know
I no longer administer the instance myself
but someone else with less experience does... so I have to inform them xD
Well, here is the official advisory - https://www.vmware.com/security/advisories/VMSA-2021-0002.html
its an ancient instance in their dedicated cloud
u can see fixed versions on the right
@desert briar the OS comes as preinstalled by the hosting provider
so idk how to even push OS updates for this
its not ESXi
its vCenter
vCenter != ESXi
the ESXi is OpenSLP heap-overflow
not RCE
but you shouldn't have your instances facing the web anyways
VMware recommends that
ESXi hosts don't even need much connectivity
https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.security.doc/GUID-084B74BD-40A5-4A4B-A82C-0C9912D580DC.html
https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.security.doc/GUID-603AF714-ABD7-429D-8B93-1701F5A80F64.html
You can add ESXi hosts to an Active Directory domain by using vSphere Authentication Proxy instead of adding the hosts explicitly to the Active Directory domain.
Theoretically it is an RCE. If enough time and manpower is put into making an exploit, lol
lol
wouldnt be surprised if it already got weaponized by some APT or something
but yeah well, common sense applies. Keep the dashboard access limited, ip whitelisted and what not
In all honesty, no clue. Isnt on the website... At the same time
there's no CVE advisory for that one
is esxi 6.0 still supported?
idk xD
the whole stack was due for reinstallation in april
vendors tend to provide security patches sometimes, if the flaw is really bad. Like Microsoft did with windows XP, ages after it ended its support
so I'll just plug those optional ports, and we good
so it might be worth checking out their release page
@desert briar with an uptime of 700 days?
nah, I dont think this was ever patched
it was switched on, installed, and has run ever since
time to say goodbye

I really wish I had another server with a proper CPU. I have an issue where I cant vmotion between my hosts as the CPUs are very different and lack each other's features
so vcenter keeps on crying that I cant vmotion a live machine from gen9 to gen8.
At the same time, how am I supposed to update the host if it requires maintenance mode, therefore shutting down vcenter and all other VMs
im too lazy to do it by hand at this point 
First time trying to set up Mikrotik RouterOS in a VM. How do I display the list of adapters? It mentions something about "interface" and "interface-list".
"/interface list print" dumps what appears to be a list... sadly, "/interface bridge port add interface=ether1 bridge=local" is the only command that works to add a bridge and apparently, it contains no interfaces. This explains why the command works and I still can't reach RouterOS from another station. hmmmm...
Anyone around to answer a question?
Don't ask to ask just ask
No, I have a serious question...just didn't want to waste time by submitting it to the universe...so here it goes:
So I have this device and between moving and other chaos, I have managed to lose both the power supply and manual. Now the manual I got from the website, no problem but I'm having issues tracking down a power supply. Sorry if this is the wrong space for this but it is technically networking for the intended purpose
oof, I don't know anything about cable networking
that looks like a filter
It's a lossless splitter
seems like something @hollow marlin would know about
8 port, in this case, a bit much for my needs but I wasn't going to scoff at free $200 worth of free equipment, lol
found my mistake in understanding. "/interface ethernet print" shows ethernet devices.
@waxen saddle rOS?
all the various menus, ppp, wireless and vlans, are all just /interface
Yup. First time installation in a VM.
First time touching it at all. I have the ISO image I'm installing on a VM to get familiar with it.
ahh
I set up 2 ethernet interfaces for the VM, but only 1 is showing in /interface ethernet print
what about /interface print
Nothing. I just have table headers #, NAME, Type, ACTUAL-MTU, etc..
I just did a full shutdown and start and now it's showing both interfaces. weird. Must be a quirk of my VM host.
No, I haven't gotten to the point of using WinBox yet. RouterOS is on a different VLAN than my main machine at the moment.
@waxen saddle it runs a mactelnet server
you can just punch in the MAC address
and connect
uses only layer 2
Actually, the 2nd interface was the interface connected to my main machine network. So now that that's up, I can see it in WinBox. Sorry for the confusion. I've been rapidly making changes and moving stuff around. 😛
@waxen saddle most interesting things to observe in rOS
are the way you set your firewall up using the configurations of the rest of the system
default configuration sets up some address and interface lists
and it attaches all the hardware ports on your device (except ether1) on your bridge
this bridge is then added to an interface list called LAN
so all ports inherit from this
same way you can move different ports or vlans onto different bridges, and then by setting up interface lists, you can use the firewall to greater effect
and same goes for address lists, which are configured in the fw settings
[admin@core.****.nl] /interface list> print
Flags: * - builtin, D - dynamic
# NAME INCLUDE EXCLUDE
0 * ;;; contains all interfaces
all
1 * ;;; contains no interfaces

All playtime is on hold now. Wife is serving as a remote judge for a competition. Can't have any weird IP stuff going on. 🙂
I know copper/fiber, I know absolutely nothing about COAX
ah ok
@boreal dove there is someone in the homelab discord that works for an ISP, pretty sure they work with coax
What about MoCa networks?
moca is coax
See the idea was to use the lossless splitter for MoCa streaming to the upstairs areas of the house
I know, but after the coax it's just normal ethernet, yeah?
Hmmm
Hey all, so I'm trying to connect to a linux laptop from a windows pc using zerotier (specifically trying to connect to a minecraft server). On my windows pc I keep getting a connection error, but if I host on my windows pc and connect on my linux laptop its fine
So basically I can connect to a minecraft server hosted on windows (using zerotier) but not vice versa
Fixed it
I was a dumb dumb and didn’t type sudo ./zerotier-one -d
Lol
That basically launches the app
Happens to the best ppls
That’s why I joined the network, but couldn’t do anything
Couldn’t be any truer
I did this mistake too much times 😆
While I worked on more than 3 servers at the time
Linux can be a pain sometimes
Most of them I was root and only 1 server I wasn't connected as root
But once you figure everything out, works much better than windows imo
Anything can be a pain
linux desktop also kinda sucks in certain ways
Depends os the distro and the desktop environment you choose
Kde is much better and smoother
everyone kinda sucks a way or another
X server
Gnome is crap
I’m using linux as a main os on my laptop, not yet on my main pc because I want to get a second gpu and more ram (so I can virtualize and game on windows and use linux for everything else)
Gdm
That's what I did
why 2 gpu's?
I have 64gb ram and 2gpus
Erina, can you help me in #tech-support ?
Full passthrough
For gpu passthrough
can't you use sr-iov?
You use it but for passing the immou
Full GPU passthrough is much better than share it regularly
what model?
HP proliant ML350p gen8 server
for a server you want linux
When they say "Mikrotik is powerful, but you have to know what you're doing" - I think that's incorrect. I think it's "Mikrotik is powerful, but you have to know what you're doing on Mikrotik".
if it has multiple cores, idk if regular windows even works for that
yeah, I'm used to vyos/vyetta/junos/edgecli
mikrotik seems completly different
And there was windows 8 on it but all storage was removed
did you install new storage?
I mean. I'm able to set up a DNS server on almost anything. I'm having some major brain farts trying to figure it out on Mikrotik.
But when boot up nothing happens
I'm not familiar myself with servers, so I really wouldn't know how HP's server bios works like. I want one though. Go though the bios and look for any obvious settings. I would highly reccomend linux
Proxmox is great for virtualization
When boot up screen stays black
like I said look though bios
Why windows so fucking crap?
How could I enter a bios when there is a black screen
oh so it doesn't even POST?
Yes
Ummh there are a lot of lights
Oke
Ty
I know I'm super happy
But it kinda huge
Like two atx pc case combinat and the fans tho
There loud
page 13 -14 is what you want to look at
Nope
basically it's a mini computer on the computer that is completely seperate but connected so if the server is shutdown that mini computer stays on and you can connect to the web interface
and you can do all sorts of stuff like turning the server on/off
or accessing the screen
Downloading on 5.1mb/s and now I can't load web pages 😆
Yeah could upgrade later but for no just try to get it work
those servers have lower clock chips than we are used to today
I have a 1060 laying around
Mc is for even a potato good
for like 5 players it'll probobly work
@weary tuskI'm using an optiplex as my server rn https://cdn.discordapp.com/attachments/387022787480387605/789118646718562314/20201217_081457.jpg
Cool
can and cannot dues of 150Mbps down and 50 up? we’re getting a new isp and going from 2 down 1 up to that what is some stuff that 150 down and 50 up can’t do
on the front?
show a pic of the front?
Back?
I'm on 40/3Mbps , 5.1/0.3MB/s
Btw when start up fans are bit loud bit some times they go crazy en supperrrr loud
yep
HP is like that
especially with drives that are not HP
You can switch the heat sinks to active fans instead those
@weary tusk Apprently it's something that can pull out? Let me look into it more
14.36gb download on 5.0/5.1Mb/s how much time will take it finish downloading the update ?
you have ethernet right?
Yes
on the back there should be a port labeled iLO or something like that
hook ethernet up to there and in your router look for a new device
yeah, and then you can try connecting to that IP
try both http:// and https://
if it gives a security warning click advanced and continue
I bought my old pc 16gb ram for trying to bring it back to life
can and cannot dues of 150Mbps down and 50 up? we’re getting a new isp and going from 2 down 1 up to that what is some stuff that 150 down and 50 up can’t do if you guys know like how many devices could be watching netflix or youtube at the same time
150 down should be enough
at that point it's a matter of wifi congestion
1080p yt takes 5 Mbps
Should I make my old pc as backup / plex server or the old af g6 server I have here ?
so theoretically 30 devices can watch yt at the same time
I7 4770 or intel xeon e5520 on my g6?
jesus
i just can’t wait to update cod in a few hours not a few days
I remember setting up HTTP caching on a T1 line. The Internet was Smokin' after I set that up.
Then everything started going HTTPS, which screwed over a lot of low-bandwidth sites.
Present, are you aware of any edge routers/modems/gateways/whatever the manufacturer calls it with coax docsis that are rackmount?
I've been looking for a way to spice up my rack besides just a white xfi sitting on the floor.
Nothing that's DOCSIS 3.0 or up 😦
No demand from the consumer market for such a config
Guessing anyone willing to pay that much for one is just using fiber?
Or is an enterprise with $$$$
but I don't really see enterprises deploying that to the edge for remote sites either
Not that I would use it, but what's around that has docsis 2.0?
I know Cisco and Juniper had docsis 2.0 cards for their older 1RU routers
Ah, line cards.
Like a cisco 1800 with a HWIC card
I think the SRX has a PIM for it, I know at least DSL/LTE which we use all the time
DOCSIS Mini-PIM Interface Overview, Software Features Supported on DOCSIS Mini-PIMs, Example: Configuring the DOCSIS Mini-PIM Interfaces
Looks like it
Yah, I see a mini-pim that's docsis 3.0
Link?
SRX Series. The Data over Cable System Interface Specifications Mini-Physical Interface Module (1-Port DOCSIS Mini-PIM) has the following features:
Wasn't aware that their SRX has docsis 3.0 support
Its a module for expansion, essentially modems within a slot. LTE, DSL, T1, COAX, etc
Not really practical for my lab but still interesting that they support it
Also you need at least an SRX320 which is what we deploy and start at ~$1200 I think
Yah, the card itself seems to be around $900 if you can find a seller
Yeah, that's quite a bit over the edge for me lol
unless if you buy it off of ebay
with no guarantees it even works with my connection
careful, all the cheap SRXs on ebay typically are unlicensed, like not even a base license
Same with Amazon and some resellers
aren't the base licenses always on there?
Nope, without it its just a brick
And the licenses are a few thousand I would imagine.
I have 900 ping in a game yay
Base for a 300 is only like $100 or so
300 does not have the PIM support
Nope, its what I got at home but mainly for labs
Know the pricing on the licenses?
I could look through some quotes
If you want
300/320 is around $270 for the base
How long does the license last?
A year, or is it perpetual?
Base is forever and even hardware has lifetime warranty
@hollow marlin Does the base include IPS?
@tribal ferry No, thats a separate license/year
Guessing that it costs quite a bit?
There of a ton of licenses that cover random features but I would not doubt its $2-300/year
Hm alright.
hmm
I am trying to compile kerenle
but
ah shit i think package bc wasnt there now it works
@dusty osprey apt build-dep <package>
installs any libraries needed for compilation
oh
ur on arch 
yea it had issues compiling sadly

pacman -S pahole
Hey guys , I was just wondering if anyone has a solution to my problem, whenever i connect my desktop through ethernet it crashes my wifi and doesnt work. I just updated my wifi. If anyone has any ideas , many thanks
so i have a HP proliant ML350 Gen8 but with no OS, would it show the Bios if no OS yet?
@weary tusk bios would most likely say: INSERT BOOTABLE MEDIUM
or go into a PXE bootloader loop
oke cuse on start up screen stay black and some times a beep
@weary tusk if you want to know what behavior of the motherboard means, the manual is usually the best source of information
😐
want a photo?
@weary tusk page 13
i have some green yellow ish and some more green yellow
btw i heard one beep on start up
@weary tusk manual is the guide on this sort of stuff
its how anyone here would go about debugging this
@weary tusk that image above
yeah
thats an HBA
BIG BRain moment*
more like a brainfart moment
Mother: You are no longer my child
@weary tusk idk what I am looking at
those leds
yeah idk what they mean
have a look at the motherboard manual, and make up your own mind on this
i'll be heading out shortly
oke, non of dimm leds are on so that oke
😆
Hey guys , I was just wondering if anyone has a solution to my problem, whenever i connect my desktop through ethernet it crashes my wifi and doesnt work. I just updated my wifi. If anyone has any ideas , many thanks
update wifi?
yeh i got faster speeds , 70mb rather than 35
but whenever i connect my desktop it cashes
i have done all the basic stuff like that
its just that specific device that does it
ok then
run the troubloeshooter
update the network adapter
do above steps in your pc
yeh i tried that but i can give it another go.
where did u get those troubleshooters tho
just the windows troubleshooter
wc
they all seem to be fine
hmm
then restart your router
then your pc
check the ethernet cable
the port
then run sfc /scannow in cmd admin
ok
k
lol
reboot your machine
restart
Got a hypothetical question for ya'll
Say you're troubleshooting a network you're not familiar with & want to locate the DHCP server, how do you go about that?
I've installed "dhcping" on my Debian system & it does contact the DHCP server successfully, but it requires a specific address pointing at the server.
Should I just do a host discovery pass with nmap & write a script that passes the results to dhcping or is there a tool that sweeps the network automatically already available?
ifconfig
I figured I'd find dhcp server info in /var/lib/dhcp but it's an empty directory
I restarted and it killed itself @topaz ridge
u mean 192.169.0.1 @waxen scroll
if im troubleshooting a network im certainly not logged into the DHCP server to do so.. lol
what do u mean
Nah just hypothetically

Like it crashed again abd keeps crashing
then run dism /online /cleanup-image /restorehealth run this now in cmd admin\
@dire flare I think wireshark would be the tool you are looking for
it a packet analyzer
so if you just set it to filter only DHCP
you can see the request and response
I'd still have to initiate the request somehow
I mean; aside from just yanking the cable/reconnecting wifi
and what MAC addresses are involved
@dire flare your OS does that
so if you set wireshark to listen
But surely not all the time
and then renew your IP address
it should send out a DISCOVER packet
@dire flare im starting my laptop up
gonna run this so I can show you
do i need to be connect to internet
It says its unknown , error 87
what
@dire flare https://i.imgur.com/Rm8ahzv.png
you can see the first packet, that's the dhcp request
with destination IP broadcast (255.255.255.255)
after which, the DHCP server replies
and you can see the source address
@waxen scroll Empty if I have a static IP set, but remains empty even if I switch to DHCP. Though my system is configured through networkmanager, I'm assuming if I used dhclient it'd give me a file in there
@dire flare network configuration on debian is in /etc/network/interfaces
same is with dhcp client config
If I just run sudo dhclient to send out a DHCP renewal request the file does appear in /var/lib/dhcp and packet capturing with tcpdump does also show the same packet you see in Wireshark.
It just seems NetworkManager sticks stuff elsewhere I guess?
Anyways, I can accomplish what I wanted by using tcpdump, looking at /var/lib/dhcp and using dhclient to ask for a renewal
Thanks
i thinnk that fixed it so thanks
oh nice
Ah it seems networkmanager holds DHCP lease info in /var/lib/NetworkManager/
That's why the other filesystem location wasnt populated on my system
So I got a server for free but I think I need a gpu cuse there is no display it stays black and cpu doesn't have intergrade gpu
what are the specs tho
Xeon e5 2609
I thought 32gb ram ddr3
En motherboard idk
HP proliant ml350p gen8
But i think the problem is no gpu
Cpu doesn't have intergrade gpu
I don't think any server vhip comes with an integrated GPU
but should still output some text UI
Well that doesn't show up than
@weary tusk do you have a serial cable?
why
because that is a way you can interface with a computer if you have no graphics output
@weary tusk Use the VGA or iLO 4 iKVM
dvi and ilo won't work for me
its not DVI
This VGA should be off the Matrox gpu
or go to iLO web GUI and use the KVM there, with the iLO port
Most servers don't use the iGPU if the CPU has one, they usually use something embedded so they can redirect video output to the IPMI
@rocky badge On my supermicro server, when i upgrade the driver for the aspeed embedded igpu, my windows installation constantly bluescreens and freezes up at various times during the day.
rip
I have to leave it outdated in order for my server to function correctly
I think i have a defective supermicro board
its the same board that killed my intel xeon 1245 v4 cpu
And the same board I accidently plugged a gpu power connector into the cpu eps port
its been through a lot at this point lol
I'm looking for a small rack mountable x86 based machine to use as a router. I've seen the Portwell CAR-3030 chassis which looks good. Anyone seen anything similar (that can be picked up on ebay for reasonable money)
@little schooner time for a dell
@waxen scroll and a new network cabinet, new 10G or better switch, and a new job
yesssss new job pls
@waxen scroll @clear igloo https://blob.rocks/UxSJLfQkWg.png
Yup....
it'll take a mansion to use a /24
UhM I'll have you know my carpet is full IoT
i just started doing wifi IoTs too, excluding washer/dryer and thermostats
ive grown angry with zwave so im switching to wifi
zwave products cost are double that of wifi and if any of those products misbehaves the whole network is in for a bad time
i started with some shelly rgbw wifi controllers and was pretty impressed with the response time. i was assuming it would suffer and that zwave was faster
Yeah shelly is nice
you'd need to build a TCP connection with wifi and zwave i dont think it does that
but moving knobs or having a sensor report that the LED needs to turn on is super quick
feels the same
I don't care ¯_(ツ)_/¯
Haha
Anyone here used the asus ax56u router ?? I need some help choosing one thanks
Or do i get a Ubiqiti one ?
or a mikrotik duck
something like a hEX S
or hAP ac2/3
@autumn bay asus sucks, their UI is total garbage
and software is buggy
So which one do you recommend under 150 gbp
what do you need?
I want wifi 6
I want a router than can handle like 10 plus devices
add a switch
you can get 24 or even 48 port switches
but smaller sizes exist too
you only need a single router, capable of routing at least as fast as your internet is
Im living in a flat for a while
@tame carbon he wants something that can handle 10 devices on wifi
Yeah sorry
and in an apartment wifi spectrum is pretty congested so wifi 6 would really help in this scenario
Something not too expensive but will work for the time being
@peak cloak idunno, lol. I've been able to get plenty of bandwidth on these mikrotik APs
with 1-2ms latency
I got the asus ax56u for the time being
well you live in a rural area you said?
asus...
I've not heard good things about asus
