| |
| 04:46 | Those timezones make things difficult :D
| |
| 04:47 | That kill message isn't important. No other messages, neither on the server nor the client?

| 16:07 | <dgroos> @alkisg, lunch/prep time!
| |
| 16:07 | I'll try again...
| |
| 16:09 | logging out of #ltsp on this computer...

| 16:18 | <alkisg> dgroos: I'll try to be available in 2-3 hours, if you are too...
| |
| 16:18 | vagrantc: epoptes is ready for a minor release, if you like!
| |
| 16:19 | * alkisg will be more available in 2-3 hours... | |
| 16:19 | <vagrantc> alkisg: cool
| |
| 16:20 | <dgroos> @alkisg, I'm available for next 2:02, then next available in 3:50
| |
| 16:20 | Either work?
| |
| 16:21 | Should I try email to list?
| |
| 16:21 | thanks for willing to help! Whichever way works best...
| |
| 16:23 | <alkisg> dgroos: btw if you can just leave open an epoptes and one client, I could take a look an tell you the outcome...
| |
| 16:23 | from now and for about 2 hours, I'll be busythough
| |
| 16:24 | !vnc-edide
| |
| 16:24 | <ltsp> vnc-edide: To share your screen with me, open Epoptes → Help menu → Remote support → Host: srv1-dide.ioa.sch.gr, and click the Connect button
| |
| 16:24 | <dgroos> Sure, do you mean to keep running epoptes...
| |
| 16:24 | ah..
| |
| 16:24 | I'll do now, will need to go off this maybe when classes start in 2 hours or so
| |
| 16:27 | interesting... can't make it work. This might be the problem.
| |
| 16:28 | I think it started because I *messed around with* setting up vnc on my server...
| |
| 16:30 | console message: socat[9211] E connect(6, AF=2 81.186.20.0:5499, 16): Connection refused
| |
| 16:40 | <alkisg> dgroos: I have 10 mins now :)
| |
| 16:40 | Let's see
| |
| 16:40 | <dgroos> ok!
| |
| 16:40 | <alkisg> Not socat, do vnc
| |
| 16:40 | lucascastro has left IRC (lucascastro!~lucascast@177-185-139-186.isotelco.net.br, Remote host closed the connection) | |
| 16:40 | <alkisg> Not the socat connection, the vnc graphical connection
| |
| 16:40 | <dgroos> ?
| |
| 16:40 | <alkisg> Or just run this:
| |
| 16:40 | !vnc-dide
| |
| 16:40 | <ltsp> 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.
| |
| 16:41 | <dgroos> I did, just didn't work
| |
| 16:41 | k
| |
| 16:41 | <alkisg> No you selected to share via console, not via graphical
| |
| 16:41 | x11vnc -connect srv1-dide.ioa.sch.gr
| |
| 16:42 | <dgroos> 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded
| |
| 16:42 | <alkisg> And the next, important one: x11vnc -connect srv1-dide.ioa.sch.gr
| |
| 16:43 | <dgroos> tried command twice...
| |
| 16:43 | <alkisg> What is the output of this command?
| |
| 16:43 | x11vnc -connect srv1-dide.ioa.sch.gr
| |
| 16:43 | <dgroos> (also, I tried the graphical a few times at first, then the console which generated that report.
| |
| 16:43 | yes, that one, 2 times.
| |
| 16:44 | <alkisg> And the output? Can you paste it here?
| |
| 16:44 | <dgroos> nothing was printed...
| |
| 16:44 | <alkisg> Or in pastebin?
| |
| 16:44 | <dgroos> none
| |
| 16:44 | Faith has left IRC (Faith!~Paty_@unaffiliated/faith, Remote host closed the connection) | |
| 16:44 | <alkisg> OK let's try this: /usr/share/epoptes-client/share-terminal 81.186.20.0
| |
| 16:45 | <dgroos> :-)
| |
| 16:48 | <alkisg> dgroos: are you viewing the client via epoptes right now?
| |
| 16:48 | <dgroos> no
| |
| 16:49 | Faith has joined IRC (Faith!~Paty_@unaffiliated/faith) | |
| 16:49 | <alkisg> OK I'll kill all vnc connections to see
| |
| 16:49 | <dgroos> just in the epoptes window
| |
| 16:49 | I had been, and that works fine
| |
| 16:50 | maybe purge x11vnc and reinstall? I'm thinking I messed up something in the setup...
| |
| 16:51 | <alkisg> main: reading version failed: not an RFB server?
| |
| 16:51 | This is what my receiving vnc says
| |
| 16:51 | <dgroos> not rfb server?
| |
| 16:54 | <alkisg> PORT=57535
| |
| 16:54 | SSLPORT=57535
| |
| 16:55 | OK the problem is in x11vnc
| |
| 16:55 | But I'm not sure about the cause, and I ran out of time
| |
| 16:55 | Let's see if we can solve it later
| |
| 16:55 | <dgroos> I googled 'not rfb server' and it says probably a firewall issue
| |
| 16:55 | Thanks so much, I'll look into firewall...
| |
| 16:55 | <alkisg> Ah, could be, sure
| |
| 16:57 | <dgroos> And, having a perhaps related problem that my clients can't access a cmapserver though I can at the pnp server. Yes, I'll look into this!

| 18:39 | <mwalters> alkisg: p sure the issues I brought up with chrome are just something with chrome. Clearing browser data seems to mitigate the issue (at least temporarily so far)
| |
| 18:40 | guessing that not being on an ancient lts version will help
| |
| 18:40 | <alkisg> mwalters: I don't remember well, is that on 14.04?
| |
| 18:40 | <mwalters> yah
| |
| 18:40 | <alkisg> Yeah noone would want to troubleshoot that one :)
| |
| 18:40 | I didn't even publish an updated ltsp in our ppa for 14.04, we completely got around that version
| |
| 18:41 | <mwalters> Yup. Even downgraded to the chrome from August, no change, same issues. Pretty sure something crept into the chrome profile or something.
| |
| 18:41 | Coworker was able to ID a segfault log, I have still yet to see it personally
| |
| 18:42 | but yeah, it's happening even when chrome is launched remotely
| |
| 18:42 | (not just via ltsp-localapps)
| |
| 18:42 | * alkisg doesn't even remember the issue though | |
| 18:42 | <mwalters> Oh, chrome suddenly closes with no error message, unable to reopen (in the case of ltsp-localapps), until the thin client is restarted (or logout/back in)
| |
| 18:43 | client syslog shows nothing important
| |
| 18:43 | <alkisg> And if you run ltsp-localapps xterm, ps aux, do you see the chrome process still there?
| |
| 18:44 | Also, the stderr from program's doesn't go to syslog. Either to the terminal, if you run it with ltsp-localapps xterm and from THERE google-chrome,or , at best, in .xsession-errors
| |
| 18:45 | <mwalters> I'll have to test other localapps, and will check in those places next time I see it
| |
| 18:46 | so far, haven't had anyone call back after clearing browser data, thankfully
| |
| 18:46 | work case... delete ~/.config/google-chrome on everyone ;)
| |
| 18:47 | <alkisg> Ah, I do remember something related, that chrome was breaking with sshfs -o follow_symlinks or something, so I disabled that
| |
| 18:47 | I guess you just never got the fix from 2013 :D
| |
| 18:47 | (the 14.04 version got the ltsp from around 2012...)
| |
| 18:54 | <mwalters> hah!
| |
| 18:54 | It *just* started happening within the last month or so, though
| |
| 19:57 | <Hyperbyte> Hey alkisg
