Logging x2go connections?
by Grigory Shamov 04 May '17

04 May '17

Hi All, This perhaps is a trivial question: but is it possible to somehow log/check history of past x2go session on the server? -- Grigory Shamov Westgrid/ComputeCanada Site Lead University of Manitoba E2-588 EITC Building, (204) 474-9625

25 Jan '17

I am not able to get the basic Shared Folder capability to run. Debian 7 Linux OS on client and server, X2go V 4.0.3.0, and XFCE Desktop. Is there something fundamental preventing this from working? Thanks in advance, - KarlW

Num Lock key in windows agent
by Olivier BILHAUT 24 Nov '16

24 Nov '16

Hi all. First of all, I'd like to congratulate all the contributors for this great work. X2go is a professional class tool for remote desktop. However... I ran into a really special thing using the windows agent in its last version (4.0.5). Sometimes, when you open the session, the "Num Lock" is usable, sometimes not. I mean, sometimes you may push the caps lock button and switch from arrows to Numeric keys, and sometimes the Key Pad is fully unusable. It happens only on windows agent as far as I know. All that I tried did not solve the issue. Did you already encounter that? Thanks. -- OB SySAdmin Fondation Hospitalière de la Miséricorde

x2goclient session icons not working
by Will Wagner 23 Nov '16

23 Nov '16

Hello, I have upgraded to 4.0.4.0 on win32. It's a minor thing but if I now set a session icon for a connection it is not displayed and I get blank instead. Is there something I need to do to get this to work? Thanks Will

x2go with SSH two-factor authentication
by Daniel Lo Nigro 17 Jul '16

17 Jul '16

Hi! My employer use two-factor authentication via Yubikey. Whenever I SSH to my development server, I use Kerberos to authenticate, and then it prompts for a Yubikey or Duo code. If I try to connect via the X2Go client, I get a message like this: Authentication failed. Check your GSSApi configuration or choose another authentication method. Checking the logs on the server, it looks like Kerberos auth is successful, but then X2Go is disconnecting once it receives the keyboard-interactive auth request. I managed to get it working using a super hacky method: I connect to my server via my regular SSH client, and forward some random port (eg. 1234) to localhost:22. Then I connect to localhost:1234 in X2Go, essentially tunneling a new SSH connection over the existing SSH connection. The server is configured to allow local connections to bypass two-factor auth, so this works around the issue in X2Go. It seems silly to tunnel SSH over SSH though. Any ideas on how to get this working properly with X2Go? It looks like Paramiko supports this configuration: https://github.com/paramiko/paramiko/pull/467 Thanks!

printing
by Jaume Ponsa 29 Jun '16

29 Jun '16

Hi, is there any documentation related to best practices about printing in x2go? I'll describe my scenario. 1) Linux : - I print Ok from my linux client 2) Mac - Impossible to show client printing pop-up 3) Windows - some of them shows the client pop-up printers but when I print to my local printer it do nothing. - some of them can't show Very strange. My x2goserver is remote (on Amazon). The ports of course are open, if not linux wouldn't work.

Clientside Printing on Mac Osx 10.11
by Mayr, Bernhard J. | elexis-austria 23 Jun '16

23 Jun '16

Hallo! Are there any special requirements to use standard ssh for clientside printing on Mac (OSx 10.11)? I have enabled remote login on the machine (this works fine). But the x2go Client cannot connect to the ssh daemon? Any ideas? Kind Regards, Bernhard

X2Go Fedora Package Archive: Provisioning of FC24 Packages
by Mihai Moldovan 22 Jun '16

22 Jun '16

Dear all I am happy to announce that from now on the X2Go package archive that provides Fedora packages of X2Go[1] also offers X2Go packages that have been built against Fedora 24 - the new Fedora release version. We hope this makes our package archive more useful. If you encounter dependency problems when installing X2Go release or nightly packages[2] under Fedora 24, please file a bug against X2Go BTS[3].
