Bug#495: failure to reconnect after abrupt (CTRL-C / SIGINT) termination of x2goclient, corrupt x2go_sessions file?
by Robert Izzard 15 May '14

15 May '14

Package: x2goserver Version: 4.0.15-0~847 (x2goserver: 4.0.15-0~847~~ubuntu12.04.1 on Ubuntu Linux 12.04.4 LTS kernel 3.8.0-39-generic, x2goclient: 4.0.15-0~847~ubuntu14.04.1 on Ubuntu Linux 14.04 LTS kernel 3.14.3-031403-generic) Please note: I have labelled package x2goserver, but the bug is displayed on x2goclient even though I *think* the bug is in the server somewhere (see below). Sometimes after an abrupt (e.g. CTRL-C, probably also network failure or laptop sleep/wake cycle) termination of x2goclient, I cannot reconnect to the server. I get errors such as the dreaded "Failure negotiating the session in stage '7'." and "Error: Wrong version or invalid session authentication cookie." instead. I am connecting through a proxy using ssh key-based authentication (using "Try auto-login" with "ssh-agent or default ssh key" on the proxy, although switching to password made no difference). I can connect with ssh through the proxy with no problem. I can *start* an x2go session with no problem. I can restart a session with no problem *provided I cleanly exit x2goclient* (e.g. by clicking on the close button on the window). If I exit x2goclient with a CTRL-C in the terminal, I cannot connect again. Note that I can connect to an NX session through the proxy without any problem and this does not have the same problem when CTRL-C. Steps to repeat: 1) On the client, open a new desktop on the server using x2goclient. (I am running KDE but I doubt it matters). 2) On the client, press CTRL-C to stop x2goclient. 3) On the client, try to reconnect -- it fails with errors (which are very hard to copy-paste as they go so fast, this is a bug in the GUI): ------------------------ NXPROXY - Version 3.5.0 Copyright (C) 2001, 2010 NoMachine. See http://www.nomachine.com/ for more information. Info: Proxy running in client mode with pid '7219'. Session: Starting session at 'Thu May 8 17:33:51 2014'. Info: Connecting to remote host 'localhost:31007'. Info: Connection to remote proxy 'localhost:31007' established. Error: The remote NX proxy closed the connection. Error: Failure negotiating the session in stage '7'. Error: Wrong version or invalid session authentication cookie. Session: Terminating session at 'Thu May 8 17:33:51 2014'. Session: Session terminated at 'Thu May 8 17:33:51 2014'. ------------------------ At this point the CPU usage of x2goclient jumps to 100% and I have to kill it (although the GUI continues to respond). This is just a minor annoyance at the moment. And in .x2go/SESSION_ID/sessions on the client, similar warnings: ------------------------ Loop: PANIC! No shutdown of proxy link performed by remote proxy. Loop: PANIC! The remote NX proxy closed the connection. Loop: PANIC! Failure negotiating the session in stage '7'. Loop: PANIC!

Session: Session suspended at 'Fri May 9 14:45:27 2014'. -------------- In .x2go/C-SESSION_ID/session.log on the server, I now have the following text repeated over and over: Session: Suspending session at 'Fri May 9 15:08:49 2014'. [then hundreds or thousands of times, with later timestamps] The problem appears to be with the file /var/lib/x2go/x2go_sessions on the server. If I back this up *before* hitting CTRL-C on the client, then do the CTRL-C, then reinstate the backup, I can restart the session with no problems. Clearly this is beyond the ability of a normal user (without root on the server) and is not really a fix, even if it does work. It seems that there is a problem with the x2go_sessions file on the server being corrupted in some way when the remote session is abruptly disconnected. This is a failure bad enough for me to stop using x2go and go back to NX. * Backing up this file all the time is not an option. * Deleting this file and continuing, as suggested at http://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=323, is not an option. * Note that unlink suggested in http://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=323, there is no *server* crash. * I have tried the other options at http://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=323, none apply here (e.g. permissions are fine). * The action that precipitates the problem is on the *client* side. * Note also that the network itself is not at fault: I can connect from a laptop in the same office (but on a different subnet) as the server, or from home to the proxy server direct. Same problem. * This seems similar to http://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=101 but the fixes are more than a year ago and presumably (?) are in the latest x2goclient already. * No amount of calls to x2gosuspend-session or x2goresume-session on the appropriate session makes any difference. * If I suspend the session with x2gosuspend-session, attempting to connect *does* set the session into the “Running” state (just as x2goresume-session). The error seems to occur after this. Thanks for all your help x2go team, I hope we can fix this because I'd like to recommend x2go for my colleagues. Rob

Bug#475: Seeing the same behavior
by Josh Abraham 12 May '14

12 May '14

I am seeing the same behavior in kubuntu 14.04 (for both client and server). I've added the x2go PPA to my system and installed the client and server on both machines. When the client connects to the server, it uses a VPN connection. The remote interface or application comes up and seems to be responsive. Regardless of usage, one-to-two cores on my CPU stay at 100% usage while running x2go. Let me know if I can provide more pertinent details. Thanks, Josh Abraham

Bug#496: x2goclient crashes X session when switching from 800x600 to fullscreen
by Stefan Baur 10 May '14

10 May '14

Package: x2goclient Version: 4.0.2.0 Hi, this bug manifests itself on Windows. Steps to reproduce: Set up an 800x600 desktop session and connect. Switch it to fullscreen using Ctrl-Alt-F once it's active. Result: X (vcxsrv, the one shipped with x2goclient) server crashes. We (Mike#2 and I) have verified that this occurs on Windows 7x64 and Windows 8.1u1x64, with Debian Wheezy/Trinity and Ubuntu 14.04/MATE 1.8 on our respective servers. Q: Mike#1, is this related to #488? Something going wrong due to the error in the shortcut file parsing? Or are we seeing a different error here? -Stefan
