Re: [X2go-User] Mac client 'Can't connect to X-Server
by Neil Hunt 14 Nov '12

14 Nov '12

Paul, Unfortunately as a regular user of the Mac X2go client, this is something I've seen many times. Unfortunately, I haven't found any fix for it. The good news is that it rarely happens if you keep the X11 application open. Always open X11 before starting your X2go session. From there, you can stop/start X2go sessions, even the X2go client itself, however I almost always keep my X11 app running even when it's not being uses and then I don't get the problem you are describing. If I quit X11, especially if it's accidental during an active X2go session, then I end up with the problem you are describing and the only option is to restart the whole computer. But if I keep it open, I go for days or weeks without rebooting. Ultimately, I think we should look to move to the PyHoca gui, but we haven't been able to find any serious python developers to port it to OS X.

Many people at my work use x2go's Mac client. We have never been able to figure out how to resolve the 'Can't connect to X-Server' error without random acts (eg. rebooting). We are not sure why it comes up. This is what I do: 1. Start X11.app 2. ssh -X remotehost 3. xterm & So far this works, I get an xterm so there is nothing wrong with X11 4. Start X2Go client 5. Start a session (port 22, dsa authentication, Gnome...) 6. Client gives the error and hangs (Abort and Terminate don't do anything) and I have to close the application. The closest we got to figuring it out is that the X11.app possibly changes it's DISPLAY on restarts and perhaps the x2go client is expecting display 0. Is there any more debugging information that I could get from the client to see what exactly it is doing prior to giving the error message? We have tried some of the suggestions in the forums, such as changing permissions in X11.app (this is necessary), starting it manually before starting the client. We have also done things like messed with firewall settings, made sure hostname doesn't change on our laptops between work and home, deleted preference files, delete XAuthority files, etc. What seems to work is rebooting. Thanks, P?l

Crashing X2go sessions (was Re: [X2go-Dev] x2gobasepath and Debian Lenny)

... cross-posting this mail to x2go-user ML, seems we have a solution for the crashing situation of x2goagent...

Crashing sessions
by Paul van der Vlis 02 Oct '11

02 Oct '11

Hello, I've seen the last time session problems. Sometimes, most of the time when closing a full-screen window, the whole session is gone. I've seen this with both x2goclient and Pyhoca-GUI, but I cannot reproduce it. I know this problem from FreeNX, it's one of the reasons I switched to X2go. I think it's something in the NX libraries. Maybe it has something to do with new NX libraries? Are here more people with this issue? Is here somebody who knows more about this issue?

Logging into Xubuntu using x2go
by Benjamin Shadwick 28 Sep '11

28 Sep '11

A lot of people have noticed that logging into Xubuntu using x2go results in a stock Xfce desktop instead of a Xubuntu one. Some workarounds for this have been identified and posted at https://answers.launchpad.net/ubuntu/+source/xubuntu-meta/+question/157817in case anyone is interested.

X2go i18n team
by Mike Gabriel 27 Sep '11

27 Sep '11

Hi all, we would like to set up an i18n team for X2go. The task of this team will be the maintenance of translation files in all X2go projects that utilize translation mechanism. Do I need to be able to read and write code for this? Definitely, no! Become a member of a translation team is a possibility to be in close contact to the developer team without necessarily being able to code. Only pre-requisite: you use X2go quite regularly and no the functionalities of the X2go components... plus: your English is good enough to find good translations of menu items, dialog boxes, etc. Each translator is responsible for the translation files of his/her language. Of course, it is also possible to maintain one translation language as a sub-team (that is: one language is maintained by more than one person). Currently these applications are using translation features: x2goclient pyhoca-gui x2gognomebindings plasma-widget-x2go (KDE$ binding) x2godesktopsharing x2goadmincenter ... (possibly more to come) ... The idea is to have a dedicated mailing list for announcing x2go-i18n issues (mostly mails like: ,,i18n Team, please translate this-and-that'' and a permanent team (with fluctuations, if needed, but preferably not so much fluctuation among the team members) that feels responsible and dedicated to providing a multi-lingual X2go environment to the world. The tools that we use for translations are currently versatile. Depending on the team we will find ways to standardize the translation technologies (if the team members are flexible with using different i18n tools, then this may not be needed). So, if you are interested in contributing translations to X2go and join the development realm by this approach, please-please-please subscribe to http://lists.berlios.de/mailman/admin/listinfo/x2go-i18n and ping us developers on that list. Thanks in advance for your time!!!

x2go-server
by Thomas Ritter 26 Sep '11

26 Sep '11

Hi, we are using x2go as Terminal-server-Solution instead of an LTSP-server in the skolelinux edu-debian-environment. The TS-server works an the Clients are working well, but: 1) The RAM fills with old x2go-sessions. They are not killed by any service anytime. The used RAM grows up and the server-performance decrease. I "solved" the problem by killing all x2goagents-prozesses with cron twice a day. 2) The home-directories of my users fill with log-files like these : /home/pcag01/.x2go/S-es01-119-1313081349_stDKDE_dp24and they are not deleted. 3) My logfiles in /var/log like message or syslog grow up to a few hundred MB for example with entries like these: Sep 22 06:30:24 ltspserver01 ltspserver01 console-kit-daemon[24530]: WARNING: Record was not written to disk (File too large) Sep 22 06:30:55 ltspserver01 last message repeated 606 times Is there anyone who understands what my server makes?

Re: [X2go-User] [X2go-Dev] Debian packages + Git temporarily unavailable

Hi all, the DNS issue is settled, the new DNS settings for the x2go.org domain are now correct again.

Debian packages + Git temporarily unavailable
by Mike Gabriel 21 Sep '11

Hi all, we have a DNS provider transfer running and unfortunately, we made a mistake for the hosts code.x2go.org, git.x2go.org and packages.x2go.org. The Debian package repository and the Git site of X2go are temporarily unavailable due to DNS transfer problems. Depending on your location on the web this problem will last for at max. 48-72h.

Question about Pyhoca-gui
by Paul van der Vlis 20 Sep '11

20 Sep '11

Hello, To use Pyhoca-GUI you need 4 steps: - start Pyhoca-GUI, what only adds an icon - find and open the icon - connect to a server - start a session to that server I think for many normal people this is "complex". They would like 2 steps: - start the program, so that it's visable and not only an icon - start a connection and session to a server I am afraid this is not possible with Pyhoca GUI. Correct? What's the advantage to have a separate connection and session? With regards, Paul. -- Paul van der Vlis Linux systeembeheer, Groningen http://www.vandervlis.nl

x2goclient does not connect, Pyhoca-GUI does.
by Paul van der Vlis 20 Sep '11

20 Sep '11

Hello, Strange problem. I connect with x2goclient to a customer, it says after a very short time: "Access denied. Authentication that can continue: publickey,keyboard-interactive". When I connect using SSH with the same username and pasword and as the same user, there is no problem to connect. I've also tried Pyhoca-GUI. That worked without problems too. Can somebody explain me what's the underlaying difference? Maybe some different library is used for DNS or something like that? When I try it with x2goclient using a wrong password, there is nothing in the /var/log/auth.log on the not-working-host. When I connect to another customer with x2goclient, there is no problem. When I use a wrong password there, it is logged in /var/log/auth.log. With regards, Paul -- Paul van der Vlis Linux systeembeheer, Groningen http://www.vandervlis.nl
