Hello everyone,
please disregard my previous mailing and consider this enhanced version ...
(NOTE: dismiss it if needed as it hasn't yet been approved)
I have the following on my client when I connect to a server running the same ubuntu precise distribution:
$ cat .x2go/S-sylvain-52-1428522297_stDXFCE_dp24/sessions
Loop: PANIC! The remote NX proxy closed the connection.
Loop: PANIC! Failure negotiating the session in stage '7'.
Loop: PANIC! Wrong version or invalid session authentication cookie.
$ lsb_release -d
Description: Ubuntu 12.04.5 LTS
$ dpkg -l | egrep 'x2go|nxproxy' | perl -ne '@f=split; print "$f[1]\t$f[2]\n"' | column -t
nxproxy 2:3.5.0.31-0~605~ubuntu12.04.1
x2goagent 2:3.5.0.31-0~605~ubuntu12.04.1
x2goclient 4.0.3.2-0~800~ubuntu12.04.1
x2goserver 4.0.1.19-0~1064~ubuntu12.04.1
x2goserver-extensions 4.0.1.19-0~1064~ubuntu12.04.1
x2goserver-xsession 4.0.1.19-0~1064~ubuntu12.04.1
Has anyone encountered this ? I had this working at some point and it appears a regression may be at play on the server side. I can replicate this on any ubuntu precise server within the same network and I can also replicate it when connecting to localhost!
I googled the problem and it seems to have been reported many years ago so perhaps someone on this list can provide some quick insight?
On my ubuntu server (also 12.04.5) I have the following :
$ dpkg -l | egrep 'x2go|nxproxy' | perl -ne '@f=split; print "$f[1]\t$f[2]\n"' | column -t
nxproxy 2:3.5.0.31-0~605~ubuntu12.04.1
python-six 1.8.0-1~bpo70+1~0x2go~ubuntu12.04.1
x2goagent 2:3.5.0.31-0~605~ubuntu12.04.1
x2goclient 4.0.3.2-0~800~ubuntu12.04.1
x2goserver 4.0.1.19-0~1064~ubuntu12.04.1
x2goserver-compat 4.0.1.19-0~1064~ubuntu12.04.1
x2goserver-extensions 4.0.1.19-0~1064~ubuntu12.04.1
x2goserver-xsession 4.0.1.19-0~1064~ubuntu12.04.1
I changed loglevel=debug on the x2go server to look for clues but nothing caught my attention. Note that with the same client (running at home) I can connect to other servers running Debian squeeze and wheezy, on the same network as the ubuntu precise server (at work).
On my debian squeeze servers, I have the following:
$ dpkg -l | egrep 'x2go|nxproxy' | perl -ne '@f=split; print "$f[1]\t$f[2]\n"' | column -t
libnx-x11 2:3.5.0.28-0x2go1+git20141113.546+squeeze.main.1

x2goserver-xsession 4.0.1.18-0x2go1+git20141006.949+squeeze.main.1
And on my debian wheezy servers, I have the following:
$ dpkg -l | egrep 'x2go|nxproxy' | perl -ne '@f=split; print "$f[1]\t$f[2]\n"' | column -t
libnx-x11 2:3.5.0.27-0x2go1+git20140701.511+wheezy.main.1

x2goserver-extensions 4.0.1.17-0x2go1+git20141003.946+wheezy.main.1
x2goserver-xsession 4.0.1.17-0x2go1+git20141003.946+wheezy.main.1
Thanks in advance for any help and x2go is a great piece of software BTW!
... hopefully, I can get it to work just as nicely on ubuntu.
