x2go client for mac osx
by Ricardo Díaz Martín 14 Nov '12

14 Nov '12

Hi, Is there somebody with x2go client working in MAC OS X Leopard or Snow Leopard? I have try in two different mac box and I always get the same message info "Can't connect to X-Server. Please check your settings". In settings looks like all ok (path to X11.app in mac osx is ok and verify it got right permissions). X-Server in both macs are installed and running. I have try to connect to nomachine linux server and X works fine. Some tips? Regards, Ricardo Díaz

BUGS: x2godesktopsharing
by Mike Gabriel 28 Sep '11

28 Sep '11

Hi Alex, today I have implemented basic X2go desktop sharing client support in Python X2go. The commit I already uploaded to X2go Git is very basic and needs quite some fine-tuning and testing before I will weave it into PyHoca-GUI. However, with pyhoca-cli it is already possible to test the desktop sharing client code in Python X2go. While working on that I have encountered two problems, though: 1. When the x2godesktopsharing tray applet gets killed by SIGTERM it does neither remove its socket file /tmp/x2godesktopsharing_... nor its lock file... As a consequence, the x2golistdesktops script returns stale desktop sessions resulting from stale x2godesktopsharing lock/socket files. x2godesktopsharing only removes its socket/lock files if the ,,Beenden'' item in the applet's tray menu is clicked. 2. When connecting to x2godesktopsharing the x2godesktopsharing applet always shows wrong username: (a) session already running as user-a, start x2godesktopsharing (b) connect a shadow session to user-a's session (as user-b) (c) user-a then gets asked if it will accept an incoming connection from user-a(!!!!), here it should ask for user-b instead The basic question here is a question of concept. I currently only see this approach: (i) -> pass another parameter from x2gostartagent to x2godesktopsharing (client mode), this parameter will be a representation of the connecting user name (and maybe gecos field?) It would be good to fix both issues some time in the near future. Apart from these two issues x2godesktopsharing works brilliantly. Another cosmetic change could be an improvement of x2godesktopsharing's whitelist/blacklist editor (e.g. add users manually, maybe even add groups manually etc.). But that is rather of a lower priority...

3.99 Testing - Multiple X2goclient instances fail
by John A. Sullivan III 15 Aug '11

15 Aug '11

I believe I have tested this on both Linux and Windows - becoming a bit of a blur after a long hot day!. In previous versions of X2GoClient, I could open multiple instances and connect to multiple different X2Go Server simultaneously. It was not official and it generated a few errors but it worked. This is actually a highly desirable feature for a possible very large account of ours. For some reason, that has stopped working in 3.99. It did not work in 3.0.1.18 either. It does work in Pyhoca so I do not think it is an impossibility. If at all possible, we would like to see this functionality restored - preferably officially but even accidentally as it was would do :) Thanks - John

core dev-team testing x2goclient during next week
by Mike Gabriel 06 Aug '11

06 Aug '11

Hi all, thanks to everyone (esp. to John) for taking such a meticulous look at the latest x2goclient 3.99.0.0 (Win32 version). There obviously seem to be quite some open issues that we have to cross-check on our own development/testing systems. Alex (the core developer of x2goclient) will do that ASAP, we hope to come up with some feedback, patches, comments by the end of next week. If that gets delayed, I will let you know about the delay and come up with another timeline. Unfortunately, as X2go is not a commercial project, this cannot be any quicker. We apologize for this!!! If there are people out there you can read/write C code, please feel free to clone git://code.x2go.org/x2goclient.git and cross-read the code. Some other problems, however, may arise from x2goagent, as well. So you might use git://code.x2go.org/x2goagent.git for lecture as well...

Eliptical SSH keys and X2go client (was Re: [X2go-User] Autolaunching)
by Mike Gabriel 31 Jul '11

31 Jul '11

Hi, I am cross-posting this x2go-user thread to x2go-dev as it seems that there is a SSH problem when eliptical curve keys are used... On Sa 30 Jul 2011 23:23:40 CEST CACook(a)quantum-sci.com wrote: > OK it seems clear that this is a bug with the client. > > It does not recognize the new eliptical curve keys. x2goclient uses the system's SSH library (libssh). Could you check the version you have installed on your system? I would be good if you could compose a complete bug report (what did you do, what did you expect, what happened, what systems and versions did you use, etc.), so that the devs have a cook recipe to reproduce your issues. Could you also test your pub/priv key pair with pyhoca-gui? It uses an SSH implementation called Python Paramiko and it is a complete rewrite of libssh-stuff in Python. I suppose it neither supports those keys but it would be good to know for certain. Thanks for staying on this!!!

x2go in OS X Lion
by Joachim Tingvold 31 Jul '11

31 Jul '11

Hi, I'm not sure if this has been discussed previously, but PowerPC-support was removed in OS X Lion. Since x2go uses nxproxy, which is compiled on PPC, it fails to display the remote desktop (it connects and creates sessions just fine), yielding the following error in Finder: "You can't open the application nxproxy because PowerPC applications are no longer supported." A quick Google-search yields a FAQ at NoMachine[1] explaining the issue. Trying to find a way to resolve this, I downloaded the NX 4 Preview for OS X, but the nxproxy isn't present in these packages. Has anyone found a way to make x2go work in OS X Lion? [1] <http://www.nomachine.com/ar/view.php?ar_id=AR05I00593> -- Joachim (sorry for long lines, Mail.app is still broken in Lion, and now there is no way to downgrade to the Mail.app-version in 10.6.1 (-: )

Nice day to everyone! Regarding: x2goserver 3.0.99.5-0~x2go3+wheezy~heuler~20110728~182~build1 If "x2gogetagent" is to keep its place below ".../lib/x2go/" then the following change seems appropriate, because otherwise session-resuming fails with error-message "x2gogetagent not found". .../bin/x2goresume-session (upstream): 30 31 X2GO_AGENT_PID=`x2gogetagent $SESSION_NAME` 32 33 X2GO_ROOT=${HOME}/.x2go 34 X2GO_RESIZE=0 35 X2GO_FULLSCREEN=0 36 37 X2GO_LIB_PATH=`echo -n \$(x2gobasepath)/lib/x2go` 38 .../bin/x2goresume-session (fixed): 30 31 X2GO_ROOT=${HOME}/.x2go 32 X2GO_LIB_PATH=`echo -n \$(x2gobasepath)/lib/x2go` 33 X2GO_AGENT_PID=`${X2GO_LIB_PATH}/x2gogetagent $SESSION_NAME` 34 35 X2GO_RESIZE=0 36 X2GO_FULLSCREEN=0 37 Best wishes and happy hacking!

PROPOSAL: X2go session cache deletion (client-side)
by Mike Gabriel 30 Jul '11

30 Jul '11

Hi all, for post-Baikal coding here the first proposal to get rid of (or minimize) the lost .x2go/<session> directories: 1. Place file ,,profilename'' in the .x2go/<session-name> directory to become able to relate between server and client. 2. When connecting to an X2go server do the following: o do everything from now in background, 2 minutes after the session has started o get a session list from the server o check local session directories in .x2go/ for matching sessions o for any session that is in R or S state on the server: keep the local session directory o for any other session directory on the client that contains a profilename file with the currently connected profilename in it: remove the local session directory as the session is obviously not valid any more on the server 3. On session profile renames: remove all cached .x2go/<session> directories for the old session profile name. Feedback!!!

3.00 Testing - BIG PROBLEM - Printing crashes
by John A. Sullivan III 30 Jul '11

30 Jul '11

Hello, all. I tested printing for the first time on a heuler client using our old 3.0.1-5 servers. Printing crashes x2goclient completely. I was not able to print even once thought I tried several different ways including sending the print to PDF reader instead of the printer. The print dialog appears and, as soon as I click on print, the entire x2goclient disappears. I don't have time to run an strace on it today. I believe Phil has also seen this. Has anyone else? We certainly can't release it this way. Thanks - John

3.99 Testing - stray deletes
by John A. Sullivan III 29 Jul '11

29 Jul '11

Hello, all. At first I thought this was my imagination but it is happening regularly and is a serious problem. Since upgrading to 3.99 on Debian Squeeze, I am getting lots of random delete key activations. I'll be reading a mail and it will suddenly disappear or a couple of mails will disappear from the Inbox. I then unhide deleted mails and see they've been deleted. I'll have some code open or a document and I'll suddenly see the document changed indicator activated. I'll look and there are missing letters. It's not even rare - it is a many times a day event. Has anyone else noticed this? - John
