| 08:15 | <alkisg> Hello Bruno Binet
| |
| 08:15 | !vnc-dide
| |
| 08:15 | <ltspbot> vnc-dide: To share your screen with me, run this: sudo apt-get --yes install x11vnc; x11vnc -connect srv1-dide.ioa.sch.gr - this is a reverse connection, it doesn't need port forwarding etc.
| |
| 08:17 | <alkisg> Hmm the IRC <=> matrix bridge lags a lot
| |
| 08:18 | I'll paste it manually:
| |
| 08:18 | Bruno: vnc-dide: To share your screen with me, run this: sudo apt-get --yes install x11vnc; x11vnc -connect alkisg.ltsp.org - this is a reverse connection, it doesn't need port forwarding etc.
| |
| 08:30 | Bruno Binet: ok sorry back, I was installing debian/kde to a school remotely :D
| |
| 08:31 | Bruno Binet: so to access the client, you ssh to the client?
| |
| 08:31 | Maybe that interferes, as it creates a second login
| |
| 08:31 | Do you ssh as bruno, or as root?
| |
| 08:31 | Why don't you use epoptes which is much simpler?
| |
| 08:31 | That might be the problem then
| |
| 08:31 | Do you have root access to the client?
| |
| 08:32 | Open a terminal, and connect to the client as root
| |
| 08:32 | Even as bruno first, then sudo, whatever
| |
| 08:32 | Let's minimize the interference in any case
| |
| 08:32 | Get me root client access in any way
| |
| 08:37 | Bruno Binet: so, by using "login bruno" on the client, via root ssh, everything works
| |
| 08:38 | Now I'll log you out from there, and I want you to try to login as bruno on the client, on vt2, on console
| |
| 08:38 | No
| |
| 08:40 | Bruno Binet: now try to reboot the client and login as bruno on vt2 again
| |
| 08:43 | It could be
| |
| 08:43 | Or it can be related to your ssh'ing to the client
| |
| 08:43 | As then the ssh dir is in use while trying to remount it
| |
| 08:44 | It's best to set up root ssh like I did, with authorized_keys
| |
| 08:44 | Put an authorized_keys to /root/.ssh via ltsp.conf
| |
| 08:44 | (your id_rsa.pub)
| |
| 08:45 | woernie has left IRC (woernie!~werner@p200300dd3f0cf400d16433c59c634f51.dip0.t-ipconnect.de, Ping timeout: 240 seconds) | |
| 08:45 | <alkisg> No, you can use mkdir, echo 'key here' > ...
| |
| 08:46 | Open a discussion issue if you want details
| |
| 08:47 | POST_INIT_CREATE_SSH_KEYS="mkdir -pm 700 /root/.ssh
| |
| 08:47 | echo 'your key here' > /root/.ssh/authorized_keys
| |
| 08:47 | chmod 700 /root/.ssh/authorized_keys"
| |
| 08:47 | Then you can ssh root@ltsp26.local
| |
| 08:47 | You're welcome :)
| |
| 08:49 | Bruno Binet: xvnc4viewer -listen
| |
| 08:49 | Yeah, you could also use epoptes which is even better ;)
| |
| 08:50 | <fiesh> are you talking to yourself?! or is this some matrix gateway stuff?

| 08:50 | <BrunoBinet[m]> Thanks a lot for your support!
| |
| 08:50 | I will look at that
| |
| 08:50 | have you changed anything?
| |
| 08:50 | I'm now powering my rpi from one of the USB port of my laptop (the server)
| |
| 08:50 | I see, great, thank you
| |
| 08:50 | BrunoBinet[m] has left IRC (BrunoBinet[m]!~bbinetmat@2001:470:69fc:105::68c6, Excess Flood) | |
| 08:50 | <alkisg> It would make troubleshooting so much easier, and it's in the default installation instructions
| |
| 08:51 | Yes, but only in debian/ubuntu
| |
| 08:51 | woernie has left IRC (woernie!~werner@p200300dd3f0cf400d16433c59c634f51.dip0.t-ipconnect.de, Remote host closed the connection) | |
| 08:54 | <alkisg> You connect to me with x11vnc -connect alkisg.ltsp.org
| |
| 08:54 | I listen, you connect
| |
| 08:54 | So it's safe, as I don't expose a vnc server anywhere
| |
| 08:56 | Yes (re port)
| |
| 08:56 | Thank you, have a nice day too!
| |
| 08:58 | Were you already logged in, and a bit later, it stopped working?
| |
| 08:58 | Did you try to `ssh bruno@client` in the meantime?
| |
| 08:59 | OK let's see, vnc to me again
| |
| 08:59 | x11vnc -connect alkisg.ltsp.org
| |
| 09:01 | Bruno Binet: type here not in the terminal
| |
| 09:01 | I have too many windows open to check there :)
| |
| 09:01 | Try with a good power adaptor
| |
| 09:01 | Maybe that's the whole problem

| 09:28 | <BrunoBinet[m]> ok
| |
| 09:28 | yes
| |
| 09:28 | (closing x11vnc now)
| |
| 09:28 | That's great
| |
| 09:28 | epoptes works also in a non-ltsp environment?
| |
| 09:28 | I hope I'll be able to contribute some stuff to LTSP in the future
| |
| 09:28 | <alkisg "Were you already logged in, and "> yes
| |
| 09:28 | I've just issue "ls" again at the tty2 client screen and it fails now :(
| |
| 09:28 | ok
| |
| 09:28 | (seem to work fine for now)
| |
| 09:28 | <alkisg "Did you try to `ssh bruno@client"> no
| |
| 09:28 | let's do that

| 10:33 | <alkisg_web> fiesh: matrix.org has been suffering spam attacks, and synchronization with other servers and IRC is very slow, it can take from minutes to hours
| |
| 10:33 | We were talking normally with bruno on matrix with no lags in the meantime

| |

| |

| 17:19 | <alkisg> Hi vagrantc! Iperf in bullseye has a bug that breaks epoptes network benchmark,
| |
| 17:20 | The sid version fixes it, but its too late in feature freeze now to migrate it, right?
| |
| 17:52 | <vagrantc> maybe
| |
| 17:53 | from the looks of it, that version really should have not been uploaded to unstable at this point...
| |
| 17:56 | alkisg: might be possible to backport a specific fix for a bullseye point release
| |
| 18:06 | <alkisg> Specifically, reverse -r doesn't work, but i haven't looked at the code
| |
| 18:06 | It just hangs
| |
| 18:12 | (today I installed my first bullseye+kde+ltsp in a school library)
| |
| 18:30 | vagrantc: btw the reason that iperf was uploaded is because the bullseye version is rather broken: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=983201
| |
| 18:31 | (was uploaded to unstable)
| |
| 18:55 | <vagrantc> alkisg: someone would need to request an unblock, not sure if that will happen
| |
| 18:56 | <alkisg> Thank you vagrantc, I don't think it's worth the trouble then, I can use a PPA for bullseye for such cases
| |
| 18:56 | * alkisg needs to take a second look to OBS | |
| 18:56 | <vagrantc> https://tracker.debian.org/pkg/iperf
| |
| 18:56 | it would also need to wait ~16 more days ... presuming bullseye doesn't release before then
