dgroos: I'm here if you're still awake :)
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?

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

<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
16:40lucascastro 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
16:44Faith 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
16:49Faith 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!

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
