I get an ssl error when I try to use 3.99.2.2.

I redirected stderr and ran the app. This is the output:

x2go-INFO-1> "Starting x2goclient..." x2go-WARNING-1> "Can't load translator: :/x2goclient_en_gb" x2go-WARNING-2> "Can't load translator: :/qt_en_GB" x2go-INFO-3> "Started x2goclient." x2go-INFO-8> "Starting connection to server: 172.20.0.2:22" Object::connect: No such slot ONMainWindow::slotTunnelOk()

Looking at the source code it appears that the sshconnection comes up and calls the slot slotTunnelOk(int). That function checks if winServersReady and if not tries to call itself again in 100mS by calling QTimer::singleShot ( 100, this, SLOT ( slotTunnelOk() ) );

The int argument is missing in slotTunnelOk and so it fails and the app then hangs.

Does that sound like a reasonable analysis?

Rather than trying to build the code myself could someone doa build with that change and I'm happy to test it.

Thanks Will

Hi,

having exactly the same behaviour with several distributions (Xubuntu 14.04 LTS, latest Debian). I tested different x2go-server versions from 4.0.1.16 to 4.0.1.19.

As a workaround I am using x2go client 3.99.2.2. With v3 I am able to resume sessions without problems.

I tried every possible v4 client without success on several windows versions (windows 7 and windows 8).

Regards,

Jan

Hello,

I have just setup a new server running debian jessie with x2go server (4.0.1.18-0x2go1+git20141006.949+jessie).

I have windows client 4.0.3.2

The first time I connect it all works. However on a subsequent attempt to resume it doesn't work. After entering password the client pops up the connecting dialog never outputs any text even though I have sow details checked. I also get the task bar popup saying it has connected although all options are greyed out. It appears to sit there forever at this point.

If I look at the server logs I see: Mar 3 11:42:43 waldorf2 /usr/bin/x2goresume-session: client 172.20.1.8 has successfully resumed session with ID willw-50-1425325134_stDXFCE_dp32 Mar 3 11:43:14 waldorf2 /usr/bin/x2gosetkeyboard: /home/willw/.x2go/C-willw-50-1425325134_stDXFCE_dp32/keyboard did not appear within 30s after agent startup

So it appears that the client has got stuck part way though resuming? Anyone got any ideas what this could be? Where can I look on windows for log messages from the client?

Thanks Will

Sorry, you are right I meant an ssh error. It was to do with an unsupported key exchange of some kind.

I redirected stderr and ran the app. This is the output:

Yes, nothing extra useful gets output.

I realise I never did this properly. When I do run it with --debug it often works and this error only occurs infrequently. I assume it is because writing out the messages slows things down just enough that when slotTunnelOk is called winServersReady is now true.

The debug output is: x2go-INFO-1> "Starting x2goclient..." x2go-WARNING-1> "Can't load translator: :/x2goclient_en_gb" x2go-WARNING-2> "Can't load translator: :/qt_en_GB" x2go-DEBUG-onmainwindow.cpp:1208> Removing apps from tray x2go-DEBUG-onmainwindow.cpp:1176> Plugging apps in tray. x2go-DEBUG-onmainwindow.cpp:9817> Getting Xorg settings. x2go-INFO-3> "Started x2goclient." x2go-DEBUG-onmainwindow.cpp:495> "$HOME=C:/Users/willw" x2go-DEBUG-onmainwindow.cpp:2123> Reading 4 sessions from config file. x2go-DEBUG-onmainwindow.cpp:9543> Starting win servers... x2go-DEBUG-onmainwindow.cpp:9895> "C:/Users/willw/.x2go/etc/sshd_config created." x2go-DEBUG-onmainwindow.cpp:9312> got localhost x2go-DEBUG-onmainwindow.cpp:9334> Port is free: 7022 x2go-DEBUG-onmainwindow.cpp:9951> Creating desktop: x2go_willw x2go-DEBUG-onmainwindow.cpp:1208> Removing apps from tray x2go-INFO-8> "Starting connection to server: 172.20.0.2:22" x2go-DEBUG-onmainwindow.cpp:2702> Start new ssh connection to server:"172.20.0.2":"22" krbLogin: false x2go-DEBUG-sshmasterconnection.cpp:202> starting ssh connection without kerberos authentication

Should I log a bug about the slot being wrong?
