USB only SUCKS in a lot of cases such as a data center or lab environment

#

There aren't any native USB comm servers that I'm aware of

little schooner Feb 25, 2020, 7:36 PM

#

@ChanoAndersen what's the purpose of screen?

#

@craggy parcel

vapid dune Feb 25, 2020, 7:38 PM

#

screen just lets you not have it taking up your main terminal

#

and so you can detach/reattach

#

kinda like tmux

#

https://en.wikipedia.org/wiki/Terminal_multiplexer see bottom of this

waxen scroll Feb 25, 2020, 7:52 PM

oh sweet summer child. i see that @little schooner has never used IRC/Shells before

sturdy mirage Feb 25, 2020, 7:55 PM

#

@craggy parcel I have 2 Cisco routeurs with usb, 2 switches with USB but this damn layer 3 switch has this weird RJ-45 connection ant this is extremely annoying

@craggy parcel what's the purpose of screen?
@little schooner Screen is a perfect terminal program on mac and linux. 😉

@craggy parcel I have 2 Cisco routeurs with usb, 2 switches with USB but this damn layer 3 switch has this weird RJ-45 connection ant this is extremely annoying
@sturdy mirage Old or new switch? I think the 2901 was the first cisco product I saw with a USB console.

#

There aren't any native USB comm servers that I'm aware of
@clear igloo ANYTHING with sufficient USB ports will work. Perhaps powered hubs will make it great as well.

clear igloo Feb 25, 2020, 7:57 PM

#

@craggy parcel When you have over 600 devices in a small lab to deal with you need a proper console device

craggy parcel Feb 25, 2020, 7:58 PM

#

No idea how those so called console devices works.. So perhaps you're right, perhaps it can be archived with a linux box with LOTS of USB ports.

clear igloo Feb 25, 2020, 7:58 PM

#

When I can get 32 ports in 2RU for console connections and don't have to troubleshoot some powered USB hub and just plug RJ-45 into a patch panel, it's so much simpler 🙂

#

It's just a 2801 router with 4x octal cables to a patch panel

#

You just SSH or Telnet to a single IP/port similar to how the USB stuff works but you don't have dozens of USB dongles everywhere 😛

craggy parcel Feb 25, 2020, 8:01 PM

#

I suppose you can make something nice, also you can have a much higher port density with USB. 😉

#

Actually, you should be able to make a USB->RJ45 cable, as USB are only what? 5 wires?

sturdy mirage Feb 25, 2020, 8:02 PM

#

it's an old one, I haven't used it for months, idk the référence ...

#

@craggy parcel usb have 4 pins, 5v, 0v, data+, data-

#

@craggy parcel

craggy parcel Feb 25, 2020, 8:04 PM

#

Nice, that makes it possible to have 2 USB lines in one RJ45 port. 🙂

#

Don't know if the lines will interfere with each other, though..

little schooner Feb 25, 2020, 9:05 PM

#

@waxen scroll I guess I'm very used to just using Ctrl Alt F<1-3> keys changing terminal sessions

#

But wait, screen doesn't work if there's no GUI right?

#

How am I going to deattach it to a blank space

waxen scroll Feb 25, 2020, 9:07 PM

#

CTRL+A+D

#

i think its screen -x to reattach

little schooner Feb 25, 2020, 9:08 PM

#

I'll have to try it

waxen scroll Feb 25, 2020, 9:10 PM

#

you can run many of them at once but theres other commands you need

craggy parcel Feb 25, 2020, 9:16 PM

#

@little schooner screen is a text mode application, similar to tmux, that seems to have become more popular. I've never had a need for features screen didn't have.

vapid dune Feb 25, 2020, 9:26 PM

#

screen -r r for reattach

craggy parcel Feb 25, 2020, 9:30 PM

#

If it will even work. 😉 But in that case, there's -D -RR never had that fail.

fervent brook Feb 25, 2020, 9:38 PM

#

if you ever get the chance, use a terminal without a monitor

craggy parcel Feb 25, 2020, 9:49 PM

#

@fervent brook And that would be done how? Blindly typing, and hoping for the best?

#

Or old mainframe style, with a line printer and a "typewriter"?

fervent brook Feb 25, 2020, 10:12 PM

#

i mean, the first option works if you're good enough

sturdy mirage Feb 25, 2020, 10:24 PM

#

I'm quite New to Linux shell and the whole idea of typing commands blindly is frightening 😭

craggy parcel Feb 25, 2020, 10:31 PM

#

Well, I've shutdown a machine blindly once. It had a CRT screen, that has become so dim, it was impossible to see anything. Had to shut down the machine, before disassembling and adjusting the monitor.

vapid dune Feb 25, 2020, 10:41 PM

#

just pull the power cable 😄

craggy parcel Feb 25, 2020, 11:07 PM

#

The machine was in the way. 😉 Unless you meant, to the machine, without shutting down.

fervent brook Feb 26, 2020, 3:16 AM

#

was the monitor attached to the System?

vapid dune Feb 26, 2020, 5:20 PM

#

o.O I wonder how long until we start seeing WPA3

little schooner Feb 26, 2020, 5:45 PM

#

@vapid dune is it already cracked?

vapid dune Feb 26, 2020, 5:45 PM

https://www.zdnet.com/article/new-kr00k-vulnerability-lets-attackers-decrypt-wifi-packets/

#

I mean among other vulnerabilities

#

I've been using VPN on my phones and laptops mostly

#

maybe I should go WPA2 enterprise but it's annoying to run multiple auths (for devices that don't support it)

craggy parcel Feb 26, 2020, 5:51 PM

#

was the monitor attached to the System?
@fervent brook Yes. Via a VGA cable, that was not detachable on the monitor side.

little schooner Feb 26, 2020, 5:59 PM

#

@vapid dune I tried using wpa2 enterprise with unifi ap but the way they implemented radius client, it stops working for no reason

#

So I had to give up on it because it was causing many calls from family

#

Unifi doesn't implement it right

vapid dune Feb 26, 2020, 6:00 PM

#

hmm I've been using mac assigned vlan with a radius server. no issues so far

little schooner Feb 26, 2020, 6:01 PM

#

Using a Cisco AP never has failed me. I tried that at the school I volunteered at

vapid dune Feb 26, 2020, 6:01 PM

#

I'm too lazy to set it up lol

#

if the radius server were built into the ui it would be nice...

little schooner Feb 26, 2020, 6:01 PM

#

It's worth it if your vendor supports

#

Yeah a UI built in would be nice

vapid dune Feb 26, 2020, 6:02 PM

#

like I'd probably consider one of those rack mounted routers if it had more features

little schooner Feb 26, 2020, 6:07 PM

#

That got me thinking, how safe from corruption are virtual disk files if I am running them over iscsi?

#

I tried running VM over network with workstation pro and it corrupts so easily

sturdy mirage Feb 26, 2020, 6:19 PM

#

if you have workstation pro, why not just add an esxi server ?

#

you cal litteraly drag n drop VM's between servers and workstation ?

little schooner Feb 26, 2020, 6:33 PM

#

@sturdy mirage well, I'm trying to centralize where all my VMs run from

#

How to make sure that another server can read the VM? iSCSI I presume but I don't know it's reliability

#

I tried SMB and it was failure

craggy parcel Feb 26, 2020, 7:36 PM

#

That got me thinking, how safe from corruption are virtual disk files if I am running them over iscsi?
@little schooner I've had production systems run from FreeNAS machines with iSCSI for a few years, with no problems.

#

How to make sure that another server can read the VM? iSCSI I presume but I don't know it's reliability
@little schooner I don't really like the idea myself, but a lot of people uses NFS. However, a proper SAN would be the right way to go.

little schooner Feb 26, 2020, 9:35 PM

#

@craggy parcel NFS because it doesn't require a thin or thick provision?

#

And easier to configure?

#

Or for a different set of reasons?

craggy parcel Feb 26, 2020, 10:24 PM

#

@little schooner No idea why people like it. It's old, and insecure. (I think some authentication has been implemented by now, but still.. )

I think it's just the fact that it's well supported, and easy to setup, and works quite well for multi host access, with stable networks.

strange silo Feb 27, 2020, 6:37 AM

#

NFS is really only insecure if you set it up insecurely, just have to do it right. Plus it's not like NFS hasn't actually gotten updates to make it better i.e. pNFS

#

iSCSI is way easier to multipath if you need the extra performance at the host level but the down side to iSCSI is that since it's block based if you have deduplication and compression on the backend storage the space savings are not shown at the datastore because storage controller isn't the one doing the filesystem

#

NFS you see all space savings directly

#

an enterprise gave me a server (dell PowerEdge T320) and there are 3 SAS drives in it connected to a raid card. For some reason the don't show up in VMware. The drives had windows server and other files on it. Do i have to do something particular so that they show up in VMware?

waxen scroll Feb 27, 2020, 7:34 PM

#

you need to make a virtual disk using the raid card and after that, initialize it

little schooner Feb 27, 2020, 7:35 PM

#

@subtle glen and if you want them to each show up as a separate disk, you need to create a RAID 0 for each drive

#

@waxen scroll Cisco sent me a 200 level badge on acclaim

#

I don't know what to think about it

waxen scroll Feb 27, 2020, 7:37 PM

oooook

little schooner Feb 27, 2020, 7:45 PM

#

@waxen scroll what I do know is that my prof just told me he purchased yet another NAS

#

That we don't need

#

I'm a little disappointed

waxen scroll Feb 27, 2020, 7:46 PM

#

lmao

#

like i said, ill take his money

subtle glen Feb 27, 2020, 7:56 PM

#

How do you make the virtual disk?

craggy parcel Feb 27, 2020, 7:59 PM

#

Depends on the hardware. Also, if it booted with windows, that part would probably already be done for you.

#

Also, some times you need a vendor specific version of VMWare to get the needed drivers.

subtle glen Feb 27, 2020, 8:06 PM

#

Oh so like this os?

📎 Screenshot_20200227-210641.png

craggy parcel Feb 27, 2020, 8:07 PM

#

Yes.

#

The HPE servers we use at work, needed an image from HPE, and I even think that was the drivers for the storage that were missing.

subtle glen Feb 27, 2020, 8:09 PM

#

Does the internal raid card (drives connector on mobo) counts as external raid card?

#

Cause I've tried that and the hdd's weren't turning on at all

craggy parcel Feb 27, 2020, 8:09 PM

#

I'd say no.

subtle glen Feb 27, 2020, 8:10 PM

#

Maybe it was disabled In bios idk

#

I'll try the special iso then, thank you

waxen scroll Feb 27, 2020, 8:11 PM

#

@subtle glen CTRL+R on POST unless your dell doesnt support that it should say "press ctrl+r" during raid card post

craggy parcel Feb 27, 2020, 8:11 PM

#

Seems like the latest version don't have a dell ISO yet. But 6.7.0 u3 does. Also make sure your server is actually supported by the VMWare version you try to install. That makes it so much easier. 😉

subtle glen Feb 27, 2020, 8:14 PM

#

@waxen scroll yeah I think I saw something like that during booting. I'll check

#

@craggy parcel yeah maybe that's a goos idea

waxen scroll Feb 27, 2020, 8:15 PM

#

also some servers dont power up the drives until after raid card post, not sure if thats why yours arent on

subtle glen Feb 27, 2020, 8:16 PM

#

The drives do power up when using the pcie raid card

#

It's just the on board connector that seems disabled, but I wasnt gonna use it anyways

@little schooner You need to learn on the fly

sturdy mirage Feb 27, 2020, 8:50 PM

#

@subtle glen
you probable have à PERC H710 on a PCi slot in your server, the correct combination is ctrl+r, you should connect the drives backplane to the PCi card, because it is way more powerful than thé onboard raid controller, if you have any question, just @me I work à lot with Dell raid controller, I know them by heart :)

waxen scroll Feb 27, 2020, 8:51 PM

#

TBH i dont know how hes connecting them onboard, usually dells use those trunk cables to the cards and theres no individual satas in the drive bays to bypass it

OpenDNS

Can I Block Advertisers and Ad Servers?

No, but for good reason. Blocking advertising providers at the DNS level can have adverse affects on browsing behavior and speed.
Significant reduction in speed is partially due to the process use...

Pay attention to HTTP or HTTPS being used in the sites that work and those that don't

lament wraith Feb 29, 2020, 2:19 PM

#

ooh okay

dire flare Feb 29, 2020, 2:20 PM

#

HTTP uses destination port 80 & HTTPS uses destination port 443
If only one particular type of website works then you could be looking at a firewall related issue

lament wraith Feb 29, 2020, 2:21 PM

#

okay thanks, will check out after my game

lament wraith Feb 29, 2020, 2:38 PM

#

so my home wifi connection has a router with a usb stick with a sim card in which supplies us with mobile broadband since we dont have any internet cables coming in from the street. for some reason that one blocks certain websites. i bought my own usb stick with a sim card in for mobile broadband and everything works perfectly with it.

dire flare Feb 29, 2020, 2:39 PM

#

Which sites are blocked
And your own usb stick you plug directly into your computer, without the router?

lament wraith Feb 29, 2020, 2:41 PM

#

ah yea ive tried taking the router usb to my pc and discord wont work either

dire flare Feb 29, 2020, 2:41 PM

#

If so, look at your routers settings panel, check firewall settings or possible parental control website filters
I'd also try turning off your Windows Firewall and seeing if the websites connect (then turn it back on again)
Different connections have different firewall profiles & yours could be restricture.

#

In that case it could be a restrictive policy on your ISPs side & you should be contacting them

lament wraith Feb 29, 2020, 3:01 PM

#

i think i need to run a permanent vpn for it to work

trail trench Feb 29, 2020, 3:33 PM

#

Is this Firefox DNS-over-HTTPS really as useless as it looks like to me? Like sure, the first time you access a website, you get its in an encrypted way from someone else, but after that the IP is cached on your computer, so you don't use it anymore, plus your ISP or whomever through you are connecting to the internet will see the IP of the site you are accessing and can get its domain with a simple nslookup

vapid dune Feb 29, 2020, 4:06 PM

#

it's not quite so simple with stuff like cloudflare @trail trench

#

dire flare Feb 29, 2020, 5:35 PM

dire flare Feb 29, 2020, 7:41 PM

#

You guys think you could help me explain some file transfer speed results I got?

#

Here's the relevant hardware

The machine with the user Swift
Intel i3-380m @ 2.53GHz
SATA SSD
The machine with the user Media
Intel Atom D425 @ 1.8GHz
5400RPM HDD

They were connected via Cat 5e cable on a gigabit connection (confirmed through iperf3)
I performed file transfers of a Windows iso (tar.gz'd) 3 times in both directions for one set of settings.
The results in picture related are as follows top to bottom
Swift -> Media @ MTU 1500 (default)
Media -> Swift @ MTU 1500 (default)
Swift -> Media @ MTU 6000 (max of Media)
Media -> Swift @ MTU 6000

In both cases the transfer speeds are faster in Media -> Swift direction, presumably because the mechanical drive has better read than write speed?
However once I bump up the ethernet frame size to 6000 the ratio becomes even more drastic. Swift -> Media speeds tank, but Media -> Improve.
One thing to note however, before doing these tests I performed one file transfer (same file) with MTU 6000 in a Swift -> Media direction & the transfer completed considerably quicker, with a time of 01:52
I'm wondering what the reason for the MTU 6000 speed tanking in that particular direction this time around, because otherwise keeping the frame size at 6000 makes more sense, correct?

📎 FileTransferTests.png

little schooner Feb 29, 2020, 10:32 PM

#

@dire flare at 6000 MTU, more data is going over the wire. More data incoming means increased delay for the hard drive to write it to disk. Since those bigger chunks are coming in so fast, the hard drive is probably falling behind writing those bigger chunks and takes longer whereas 1500 bursts are handled with ease

#

And yes perhaps your drive is read biased

#

It would be prudent to list the exact make and model of router you have. Why? Because some makes and models are absolute crap, overheating whenever they can't handle the load anymore, causing the chipset to reboot internally, which may explain why your wireless is dropping.

Unless you can convince your provider to give you a static IP (they sometimes will but it usually costs more) then not really. There are a few things that you can do for LAN games but not much that you can do for normal online games. There are things that the game companies could do (and a few are starting to try) but nothing on your end

If answered please @ me.
I'm having trouble with my router. Every few months or more I have issues with wireless devices disconnecting and taking multiple attempts to connect manually. I've used the cycle button on the router each time and the problem sometimes goes away. No idea why this keeps happening. On only channel 11/12 and next to no one near me can access it, so little traffic.

It's good for up to 100m?

#

Thought it was a lot shorter

clear igloo Mar 3, 2020, 12:17 PM

#

100m is the spec for ethernet cable length

rocky badge Mar 3, 2020, 12:17 PM

#

100m = 328 ft, that's correct

clear igloo Mar 3, 2020, 12:18 PM

faster speeds on the same spec lead to shorter distance before issues though

random void Mar 3, 2020, 12:18 PM

Sagem Fast 3890

dire flare Mar 3, 2020, 12:21 PM

#

You should do some iperf tests within your local network though and go by that

#

It takes out some variability of it all
If you're going by speedtest.net speeds, you could simply not have the adequate connection runs to the speedtest server you're connecting to

random void Mar 3, 2020, 12:23 PM

#

My cables are pretty separated but pretty long

#

None are over 50m though

#

It's not just speedtest, even if I do multiple downloads from different places its the same

dire flare Mar 3, 2020, 12:24 PM

#

Just do an iperf test and you'll know for sure what you're working with

random void Mar 3, 2020, 12:24 PM

#

I mean it's fast internet anyway but

#

Sure, just going to google that

dire flare Mar 3, 2020, 12:28 PM

#

You need two computers, one on each end of the network
Download the iperf3 program on both (make sure it's the same version)
Open cmd, navigate to the directory the iperf3 exe is in then do iperf3.exe -s on one side to set the server & iperf3.exe -c <ip address of server>
That'll test the connection one way, then modify the client command a little to iperf3.exe -R -c <ip of server> to reverse the test and check the uplink speed

@random void That's kinda uhh, not a gigabit
Confirm that both your NICs are running at gigabit speeds

#

But it's pretty much pinned 100mbps

random void Mar 3, 2020, 12:55 PM

#

they both say 100

dire flare Mar 3, 2020, 12:55 PM

#

Assuming your network adapters are capable of gigabit, you need to set them to operate at such speeds.
Autonegotiation of ethernet speed can at times fail

random void Mar 3, 2020, 12:56 PM

#

theyre both gigabit nics tho

#

hm

dire flare Mar 3, 2020, 12:57 PM

#

(though keep in mind that autonegotiation failing can sometimes be an indicator of cabling issues)
But not always, for now just manually set both to gigabit, see if the connection stays up & run iperf again

random void Mar 3, 2020, 12:59 PM

#

Set it to 1 Gbps full duplex

#

Which made the connection drop

#

But I dunno if it just takes a bit

@random void are both test computers plugged directly into that router of yours?

random void Mar 3, 2020, 1:00 PM

#

Yes

#

Waiting for reconnect

dire flare Mar 3, 2020, 1:01 PM

#

If it doesn't reconnect soon, replug the ethernet cable
Otherwise I'd say you definitely have an issue somewhere in the cable run

random void Mar 3, 2020, 1:03 PM

#

One of them reconnected, the other didnt

dire flare Mar 3, 2020, 1:06 PM

#

Be sure the NIC port isn't dirty and the RJ45 connector makes proper contact
Had a dumb issue with corroded contacts on my ThinkPads NIC yesterday that caused more or less the same symptoms you're having

#

If you have switches between computers A and B I'd suggest you just bring them closer & test each line of ethernet cable individually, perhaps there's only one bad egg in the basket

random void Mar 3, 2020, 1:07 PM

#

hm yeah, it connects just fine in 100 mbps full duplex but fails to connect in 1000

#

im going to try the same cable but with a different pc

#

Same thing on the other computer, except it runs at 100 even if I set it to do 1000 full duplex

#

while the other pc just disconnects if i force it

#

Seems like it might be this cable then

dire flare Mar 3, 2020, 1:10 PM

#

Do you have a shorter ethernet cable laying around to test just computer to computer?

random void Mar 3, 2020, 1:10 PM

#

Yeah somewhere

dire flare Mar 3, 2020, 1:10 PM

#

Just to eliminate the dumb off chance that something might be wrong with the NIC

#

then we can conclude that the cable run is problematic

random void Mar 3, 2020, 1:14 PM

#

Still runs at 100

#

With this cable

dire flare Mar 3, 2020, 1:16 PM

if I manually set the desktop to 1 gigabit then it wont connect

dire flare Mar 3, 2020, 1:19 PM

To confirm, this is just a relatively short cable plugged into Computer A NIC directly into Computer B NIC, without any switches or other network hardware?

random void Mar 3, 2020, 1:19 PM

#

yeah

dire flare Mar 3, 2020, 1:20 PM

#

That's extra weird then

random void Mar 3, 2020, 1:20 PM

#

they run at 100, if i force 1000 then the desktop wont connect

#

the laptop can run 1 gbps fine

dire flare Mar 3, 2020, 1:20 PM

#

If you were going through a switch I'd assume you might need to configure the switch to run at gigabit ethernet or something like that, but directly NIC to NIC things should just work

#

You've got a 3rd machine, right? Can you run gigabit between those two?

#

Sooo laptop & whatever the 3rd machine is

random void Mar 3, 2020, 1:21 PM

dire flare Mar 3, 2020, 1:26 PM

dire flare Mar 3, 2020, 1:34 PM

@random void Oh & did you actually do an iperf test to confirm the long run is a proper gigabit? Wasn't entirely clear
That's the only thing I've got on my mind still
In general though you'd have losses at one point or another on gigabit ethernet, ideally you'd have an order of magnitude faster networking at home to make full use of the gigabit, I wouldn't really expect more than ~800Mbps
850-950Mbps is what you can expect an iperf score to show on a short cable between gigabit NICs

random void Mar 3, 2020, 2:33 PM

#

I did iperf with the long run between desktop and laptop, but not between the two laptops

dire flare Mar 3, 2020, 2:36 PM

Verizon is also ass and only offers tv and internet near major cities

hollow marlin Mar 6, 2020, 6:48 PM

#

Well fiber hasn't improved much and we can already push the boundaries for wavelength, the biggest hurdle we need to overcome now is power and heat output for these SFPs. 400gb has been around for a while but only now have they been able to keep the power and heat down enough for deployment. They were previously testing years ago with SFPs the size of switches

#

With 800gig I'd assume they are using a dwdm type solution where the biggest issue is fiber bends and wave shifting

#

Were the actual fiber bends cause the light towards the edge to take a longer oath and cause sync issues due to it taking the light 1000th of nano seconds longer than the rest

jaunty talon Mar 6, 2020, 7:00 PM

Indeed, but cuts in fibers are problems also as they add db's for every fix they need to make to the cable

True but that is not an inherent problem with fiber

Doesn't appear to be on the list of OpenWRT supported routers, and v1 / v2 of the DGN2200V4 are listed as having VERY little flash / memory, so they're not recommended. https://openwrt.org/toh/netgear/start

yeah i had a read through all that stuff before on their page. I was just hoping that i may have mis-read or been mis-informed about me actually being able to do it if that makes sense..

so even if i have a V4 it is still not recommended to flash it and give it a go anyway?? because I honestly don't mind if i end up bricking it if that happens i will just go and buy one of those "travel routers" that have it enabled by default in a couple weeks time

@little schooner Well, if I don't remember wrong, once you've setup the iSCSI connection on each host in the cluster, you add the datastore once, and every host automatically picks it up. No additional configuration needed. But you will have to configure the iSCSI connection on each host individually.

pfsense will not talk across vlans no matter what rules you set. bridge the ports into one vlan.

jaunty talon Mar 10, 2020, 8:44 AM

#

yes it will. If you have vlan X and vlan Y configured in pfsense and have clients in both X and Y and their default GW (or static route for the other vlan's IP-network) is the pfSense address for both vlans and there is firewall rules in place to allow these two networks to speak with each other it will work just fine!

you would then apply the rules on your wan interface if it's a decent device you have

grand flower Mar 10, 2020, 1:00 PM

idk, I have a shitty router from my provider connected to coax with wifi turned off, and a netgear router connected to the router from the provider, and my pc is connected to the provider router with a powerline adapter. I've tried a lot of things to port forward the port but nothing works so maybe it's all because of the shitty router

craggy parcel Mar 10, 2020, 1:49 PM

#

@grand flower Do you have a public IPv6 address on your computer? (Addresses starting with fe80: is a local address, and will not be reachable outside your network segment. Other special ranges exists.)
Does the minecraft server listen on IPv6? (Not all applications listen to IPv6 by default, and some doesn't support it at all. )

If you have verified the above, check the manual for your router, most of them will block IPv6 traffic inbound by default, and you need to allow traffic from the outside. Some routers will allow you to select specific IPs and ports to allow, others will only have an all or nothing option.

grand flower Mar 10, 2020, 2:08 PM

#

@craggy parcel I assume I have a public ipv6. I only tried joining my server with localhost and my local and public ipv4. I can join the server if I'm on my network, but not outside my network.

@waxen scroll When? Are you sure it's really NAT, not just allowing traffic through a firewall?

waxen scroll Mar 10, 2020, 2:34 PM

#

so you can only advertise a /48 minimum to service providers. if you have a big datacenter you are advertising there for your sites to get ipv6 internet. if you install local internet circuits at the remote site you need to either give the whole site a /48, which is wasteful for small offices and you might not have been assigned enough space to do it, or you need to NAT to an ipv6 address that the local provider assigned you

#

when the remote sites internet fails, it then flips to the main datacenter and no NAT

#

further, many local providers dont accept BGP

Well, that's just you Well, in most cases the address management can be handled via DHCP, if I recall correctly, you can even assign ipv6 subnets with DHCPv6. Also for most users, not big enough for a /48, a single /64 will be enough.

what kind of cable

grand flower Mar 10, 2020, 3:50 PM

cat6a

with a cable cutter

vapid dune Mar 10, 2020, 3:53 PM

I think with 6a you're not supposed to have any exposed wire anymore?

#

are you asking about reterminating your own cable or using the pairs for random purposes

craggy parcel Mar 10, 2020, 3:57 PM

@hollow marlin Depends on your network size. Most devices use auto discovery, so renumbering a network is really not a big issue for most smaller networks. Using NAT is usually asking for trouble with too many applications. For networks where it's just a matter of assigning new scopes in DHCP, it's no big deal to change the addresses, but in huge deployments with a lot of internal routing, sure, you want something that does not have to change, but then you would also have a size where a /48 would be ok. A /48 is btw the minimum recommended allocation for end users, if I remember correctly.

vapid dune Mar 10, 2020, 3:57 PM

#

I'd argue your drill bit is too small

#

from what I understand terminating cat 6a is harder to do right than cat 5

craggy parcel Mar 10, 2020, 4:00 PM

#

Well, instead of using a cable with the RJ45 connector mounted on it, you could terminate the cable in a wall plug, and terminate the cable there, using premade cables for connecting devices to the wall plug..

#

The wall plugs are usually easier to mount.

How To: Terminate a Cat6A Connector

Streaming media whether data, audio or video, is on a sharp rise and users are demanding more bandwidth. That means bigger cable, commonly referred to as CAT6e, CAT6A and CAT7, and usually shielded. For maximum performance, connector and crimp tool choice is critical. Our CAT6...

@craggy parcel Sure only in a small business but there isn't much an issue but anything there than a handful of routers, no, you buy a block and are set. Even if you autodiscover between routers one side still needs to be statically set. End users get a /64

Hmm.. I was under the impression that DHCPv6 could assign the subnets for routers as well.. But I might remember it wrong...

#

Is there a diagram that explains how router can pass down public Ipv6 addresses into an internal network when it's setup like this

ISP --> Router --> Switch > Ipv6 clients with routable Ipv6 address

vapid dune Mar 10, 2020, 4:19 PM

either SLAAC or DHCPv6

@little schooner L2 or L3 switch?

L2

vapid dune Mar 10, 2020, 4:23 PM

https://chrisgrundemann.com/index.php/2012/introducing-ipv6-neighbor-discovery-slaac/ ah it's done in 2 phases

clear igloo Mar 10, 2020, 4:23 PM

#

L2 switch is easy, clients get DHCP from the router. The Router says "Hey give me an IPv6 PD (prefix delegation)" and it uses that for the pool to assign to clients

#

It will get a /128 + a PD assignment (at least in most consumer scenarios)

little schooner Mar 10, 2020, 4:25 PM

#

And that's how it divides it up to internal clients to all have public Ipv6?

craggy parcel Mar 10, 2020, 4:25 PM

#

The ISP tells the router what it's internal public prefix is, and the router does the rest.

clear igloo Mar 10, 2020, 4:26 PM

#

Yah, it uses the PD assignment from the ISP. Could be a /64 or a /60 or /56 or /48 even, just depends on the ISP policy

little schooner Mar 10, 2020, 4:26 PM

#

I see.

clear igloo Mar 10, 2020, 4:26 PM

If you get a /60 then you could subnet it per VLAN from there

not from your Router to your devices

craggy parcel Mar 10, 2020, 4:26 PM

@clear igloo Do you need to assign a global IP to the WAN side of the router? If it's just a point to point link, couldn't you just use link local addresses?

craggy parcel Mar 10, 2020, 4:32 PM

#

@craggy parcel Yah, you have to use the WAN IP the ISP gives you
@clear igloo I'm not sure if you understand my question. If I were the ISP, would I have to assign my global IPv6 addresses to the wan side of customer CPEs? Or could I just let them use link-local addresses and skip the global address part? I mean ISPs seems to routinely use RFC1918 IPs in IPv4 networks, they are no global, and not reachable for me, as the end user, even though they appear in traces.

vapid dune Mar 10, 2020, 4:33 PM

#

Isn't IPv6 supposed to have fully routable addresses everywhere

clear igloo Mar 10, 2020, 4:33 PM

#

You have some local only addresses, fe80::

#

@craggy parcel The ISP gives the global IPv6 address as a /128 from a pool to the customer WAN interface. At least that's been my experience

#

That's public routable*

little schooner Mar 10, 2020, 4:36 PM

#

Heh this shows how little experience I have with Ipv6

#

I almost never deal with it

I wish it was more common like ipv4

No real way to practice it if I struggle to find a use case for it

craggy parcel Mar 10, 2020, 4:37 PM

#

@little schooner Yeah, I'd wish so as well, only reason I have IPv6 at home, is because I can made a tunnel for the purpose, as my provider doesn't provide IPv6 for no apparent reason.

Quick question. to set up a wifi bridge to bring internet from an office to a close building, is it required to have (for example) 2 nano stations pointing each other? Or is it possible to only have one nano station sending the signal from the office and put a normal wifi router to pick up the signal or directly connect a wifi device?

craggy parcel Mar 10, 2020, 8:42 PM

#

Any device capable of acting as a wifi client, can do the trick. But not any device is equally suited. To send WiFI between 2 buildings, you will get the best result with the least work, using hardware designed for wireless point to point links.

If one of the physical servers in our environment crashes, everything on that server goes down, but within about a minute, they are all booted on the other host.

clear igloo Mar 11, 2020, 9:51 PM

#

This means that as speeds increase, the shaping progressively limits the maximum size of the packets being sent at any one time such that low latency and fairness is achieved. This impacts the maximum flows any one client can effectuate, and means a speed test will progressively get further and further from the line maximum as line speed goes up. So on 12Mbps DSL, speedtests typically measure 15% lower (or 10Mbps) with traffic management. But a 300Mbps line might only measure 160Mbps, or 53% lower, as allowing the big packets necessary to saturate the line would interfere with other, possibly more time-sensitive traffic. But overall, the traffic can move at line speed when there is no congestion, and multiple connections from multiple devices all get fair access and good throughput at all times.

#

The bigger my packet the faster it goes 😄

craggy parcel Mar 11, 2020, 9:53 PM

#

In other words, dynamic MTU? Sounds strange handling more packets should improve latency..

clear igloo Mar 11, 2020, 9:54 PM

waxen scroll Mar 12, 2020, 7:44 PM

#

edgerouter doesnt care what you use the port for

faint iron Mar 12, 2020, 7:45 PM

#

but, when I connected my switch to it with DAC cable, the switch and my computer couldn't get DHCP address, and when I set static IP on computer I still couldn't access webui

waxen scroll Mar 12, 2020, 7:47 PM

#

the port on the switch needs to be untagged unless you told the edgerouter to tag

#

im not sure about DAC cables either, ive never used them on ubnt

faint iron Mar 12, 2020, 7:48 PM

#

I'm using UBNT's dac cable

#

and switch is from mikrotik

And auto-negotiation is disabled and set to 1G

#

EdgeRouter is probably configured all ports as L3 ports so you'll need to set them to L2 as a trunk if that's what you want to do.

faint iron Mar 12, 2020, 7:50 PM

#

ohhhh

#

ok

#

I will check tomorrow on site

waxen scroll Mar 12, 2020, 7:51 PM

i was just gonna say i dont tag on my router, but i forgot i switched it

#

im not aware that you can set them to "L2" though

#

you just make a sub interface and put a vlan ID in

Anyone have experience getting a new fiber line layer to a residential location?

Unless fibre is a standard option in your area for residential then it's going to cost a lot

@waxen scroll I've setup RSPAN for all future Wireshark attempts so it should be easier for me to get packets without additional configuration

@little schooner Fantastic UI.. What about the HTTPS streaming option in the SDK section?

little schooner Mar 13, 2020, 3:44 PM

#

@craggy parcel haven't tested that but I think that's if you want your camera stream encrypted with a passphrase. If you want to see it, you provide the passphrase

craggy parcel Mar 13, 2020, 3:46 PM

#

Passphrase in HTTPS? Never heard of that..

little schooner Mar 13, 2020, 3:48 PM

#

Yeah. So the NVR client software supports reading passphrase-protected streams to prevent anyone from simply connecting to cameras via rstp or something

#

You would need to know the passphrase to decrypt the live view

#

The client software using sdk functions and that's how it communicates with the cameras and determine what features it actually supports to let you configure

#

I see. Dll messages when I'm using their ivms software

I still have to call bhphotovideo to at least start the bug report for me since hikvision is completely ignoring my request

Does anyone here use Ubiquiti Networks? If so what do you think?

craggy parcel Mar 14, 2020, 9:01 PM

#

Depends. UniFi is pretty easy to setup and maintain, however, for my specific purpose, which was certainly not something they designed it for, I had to mess a little around with how to twist the system into what I wanted to do. I did however setup a regular home network for a colleague, with all UniFi equipment, and the hardest part was getting the router online, due to the ISP locking the connection to the MAC address of the equipment for a few hours. Also the controller I setup is an external controller to the network it controls, so had to use L3 adoption, but once the router was running, the switch and APs were just plug and play.

rocky badge Mar 14, 2020, 9:16 PM

My network is all UniFi lol

If I had the money to burn, I'd replace my home network with a unifi network as well, but my current network kinda works, and suits my needs. Which makes it hard to justify getting some new toys. 😉

little schooner Mar 15, 2020, 12:08 AM

#

I'd rather switch to FS branded gear

craggy parcel Mar 15, 2020, 12:16 AM

#

Well, I'd consider ANYTHING, that has a controller as easy to use as the UniFi one, and does not require any subscription.

little schooner Mar 15, 2020, 1:15 AM

#

Now, that, unfortunately, ubnt is the only one that has the unified controller and free updates

#

Also, unrelated, mullvad is a very slow vpn provider

craggy parcel Mar 15, 2020, 1:45 AM

#

Well, I know other companies has controllers for their equipment, however, most common are access points, while it's less common to have one for routers and switches. But is there really no other vendor, that provides a similar system where no subscriptions are required?

little schooner Mar 15, 2020, 2:00 AM

Yeah, your right, really no other vendor that has everything, from ap to router to switch, unified all under one umbrella with FREE updates

do any of ubiquiti gateways have some sort of vpn like openvpn?

craggy parcel Mar 15, 2020, 11:56 AM

#

@stiff panther They have the option of making site-to-site IPSec VPN automatically, when both gateways are on the same controller (But in different sites). You can also setup IPSec manually, or use OpenVPN. Finally it can act as a PPTP or L2TP server, and PPTP client. (That's the USG in the UniFi Series)

I have a Amplifi Instant Router hooked up to my Gateway. Is there anyway to give my Amplifi the public IP Without bridge mode? Right now the IP on the Amplifi says 192.168.100.2

waxen scroll Mar 16, 2020, 2:18 PM

#

@unreal spoke the only way is to be assigned a block of static public IPs from the provider, otherwise you need to bridge

unreal spoke Mar 16, 2020, 2:47 PM

#

@waxen scroll I would put it into bridge mode but it wouldn't work. Later I found out that Orange (My ISP) need this thing called "DS-Lite". I can't turn it on in bridge mode because it always gives me the error that it can't be used in ipv4 only mode. There is no toggle in the bridge mode setting for this "IPv4 Only Mode" so that's why it won't work with bridge. Any suggestions?

Is there some setting in particular I need to be ticking to get NIC to NIC ethernet between two computers going?
For context, I have an Asus laptop with Debian 10 & a new ThinkPad T530 with Windows 10
I want to connect ethernet between the two devices & transfer files over a gigabit link.

This is pretty much plug & play on an older ThinkPad I have (SL500) but that one runs Windows 7
Both NICs and cable function fine when connected to a switch, but directly the T530 just says there's no network cable connected

waxen scroll Mar 16, 2020, 4:10 PM

#

no link light?

#

the link should come up right away as long as your cable isnt bad...

#

preferably after that you need to put static IPs on both sides

dire flare Mar 16, 2020, 4:22 PM

#

It's acting like it'd need a cross-over cable

I set static IPs on both sides & the cables are definitely good
