Us international keyboard
by Dick Kniep 16 Oct '10

16 Oct '10

Hi there, We are currently testing our application that is distributed by x2go. However we always get the us keyboard instead of the us-international keyboard. Whether I set the keyboard to us-intl or tell x2go to use the local keyboard I always get the us keyboard. Because of that, we don't have a Euro sign and also the é and è that are use in the Netherlands are not available. Has anyone seen this behaviour?

The Vanishing Mouse
by --[ UxBoD ]-- 07 Oct '10

07 Oct '10

Hello all, it was reported on the list a while ago that somebody was having an issue where the mouse pointer within the X2GO session would disappear. Well, I finally managed to get the same thing to happen to me this morning while running X2GO under Windows XP Pro. Even suspending the session and re-connecting does not resolve the problem. The issue appears to be the version of Xming that is being distributed with X2GO. Why do I think this ? I suspended my session again and then killed of Xming via task manager. This caused the X2GO plugin to fail for which I created a new FF tab and reconnected. I connected straight back to the same session and X instance as before and my mouse pointer was back in the land of the living. The question is though how can we resolve this problem ? The 6.9 version of Xming that is shipped with X2GO is ~3 years out of date now, and to get the new 7.5 branch one has to subscribe. Hmmm, this would be fine for a couple of users but when we may be handling 100,000 of them it would get a bit pricey :( Any thoughts on what can be done ? -- Thanks, Phil

reason for keeping session dirs in .x2go folder
by Mike Gabriel 06 Oct '10

06 Oct '10

hi folks, we have discussed this earlier, but I think there was no real common opinion afterwards.... On X2go server and client each session produces its own session directory in the ~/.x2go directory. From the perspective of the X2go client: is there a proper reason to keep these session directories (apart from debugging)??? I am asking because I plan to integrate session-dir-purging-support into Python X2go: after a session has been suspended/terminated the session dir on the client will be deleted. Any comments?

Python X2go - rev SSH tunnel + pulse audio support added
by Mike Gabriel 06 Oct '10

06 Oct '10

Dear list, as I am really interested in feedback... I have added SSH reverse tunneling support to the X2go client implementation library named Python X2go and that made it possible/and very easy to provide pulse audio support with Python X2go already. The Python X2go module can be tested with the PyHoca Client. Also the project homepage is now in English. http://das-netzwerkteam.de/site/?q=node/71 The Python X2go API implementation can be found here (feedback, typos etc. are welcome, also patches or collaboration): http://packages.das-netzwerkteam.de/doc/python-x2go/ I am currently building .deb-Packages for Ubuntu lucid only, but maybe some of you have a Ubuntu lucid system around. You can install the packages from deb http://packages.das-netzwerkteam.de/ubuntu lucid main with: $ apt-get install python-x2go $ apt-get install pyhoca-cli You can start the pyhoca-cli with: $ pyhoca-cli --server <hostname> --command GNOME or a bit more verbose: $ pyhoca-cli --server <hostname> --command GNOME --debug --libdebug The X2go server <hostname> must be in your known_hosts file, also the ~/.ssh/config file is considered before building up the connection.

x2go slow response
by Alejandro Alberola 05 Oct '10

05 Oct '10

Hello, While testing x2go I have seen that the mouse latency is greater in x2go than in NX. For example, if I navigate with the mouse through the options of the gnome menu the response in x2go is slower than in NX. I am using the linux versions of the clients (x2goclient/nxclient) and I have configured the link speed with the same value (ADSL). Am I doing something wrong ? Thanks. --- Alejandro Alberola

sudo permissions?
by Rob Lemley 05 Oct '10

05 Oct '10

Hey folks, I've been toying around with x2go a bit, and I'm really liking it. >From what I've seen, the overall architecture is cleaner than freenx and even neatx. Certainly none of that insanity of netcat's and fdcopy's. I was a rather disturbed by the x2goserver package adding a line in my sudoers file to allow anyone in the x2gousers group to run x2gopgwrapper as root. I checked out that script and the three scripts it can potentially call, x2gopgwrapper_{local,net,sqlite}. Other than the _net script I see no reason why root access is required. All these scripts do is access a database and run queries. The _net script as written probably needs root access, but there's no reason why with some permission adjustments on the postgres database server that it can't run unprivileged as well. As I'm just using sqlite on a single system, I did a little experiment and made some changes to run that script as an unprivileged user. I created an unprivileged x2go user with no password: (The defaults with this particular invocation of useradd are adequate, but the account can be restricted some more) useradd -r x2go So the sudoers entry becomes: #### X2GO section %x2gousers ALL=(x2go) NOPASSWD: /usr/bin/x2gopgwrapper Then permissions on the sqlite database need changing so our x2go user can run its queries: cd /var/db sudo chown -R x2go.x2go x2go Finally, the scripts in /usr/bin need to be changed so that x2gopgwrapper runs at x2go: for i in x2go*; do sed -ibak -e 's/sudo x2gopgwrapper/sudo -u x2go x2gopgwrapper/' $i; done I made these changes on my system and have not had any issues connecting. I am only using the x2goserver package at the moment; it's just this one script that gets executed as root, I don't know about any of the other packages. There's also the matter of the x2gocleansessions cleanup script... There's a couple of sudo calls in there as well, I didn't change that just yet as I've just disabled it altogether to prevent the spam it sends to my syslog. I apologize if this topic has been brought up before or is discussed in the documentation someplace; I looked around and didn't see anything. I simply bring this up in the interest of system security. The fewer things that run as root the better. The changes I describe above are my quick hack-n-fix. If I get a chance in the next few days I can throw together a proper fix and submit a patch. (And please add my vote to the yes-please git repository crowd.) X2go seems to have a lot of possibilities and potential. Thanks to Heinz and Alex for their hard work. ^_^ rob

Strange authentication requests from x2goserver
by Hoefle Marco 04 Oct '10

04 Oct '10

Hello, I am evaluating the x2go tools as an alternative to vnc (I like especially the browser plugins). On the server (debian squeeze) I recognized that the x2goserver is periodically every 5 seconds doing this: srv03-lin:/srv/http/trac/umtsrouter# tail -F -n 10 /var/log/auth.log Oct 4 19:47:33 srv03-lin sudo: root : TTY=unknown ; PWD=/ ; USER=root ; COMMAND=/usr/bin/x2gopgwrapper listsessionsroot srv03-lin Oct 4 19:47:38 srv03-lin sudo: root : TTY=unknown ; PWD=/ ; USER=root ; COMMAND=/usr/bin/x2gopgwrapper listsessionsroot srv03-lin Oct 4 19:47:43 srv03-lin sudo: root : TTY=unknown ; PWD=/ ; USER=root ; COMMAND=/usr/bin/x2gopgwrapper listsessionsroot srv03-lin Oct 4 19:47:48 srv03-lin sudo: root : TTY=unknown ; PWD=/ ; USER=root ; COMMAND=/usr/bin/x2gopgwrapper listsessionsroot srv03-lin Oct 4 19:47:53 srv03-lin sudo: root : TTY=unknown ; PWD=/ ; USER=root ; COMMAND=/usr/bin/x2gopgwrapper listsessionsroot srv03-lin Oct 4 19:47:58 srv03-lin sudo: root : TTY=unknown ; PWD=/ ; USER=root ; COMMAND=/usr/bin/x2gopgwrapper listsessionsroot srv03-lin Oct 4 19:48:03 srv03-lin sudo: root : TTY=unknown ; PWD=/ ; USER=root ; COMMAND=/usr/bin/x2gopgwrapper listsessionsroot srv03-lin Oct 4 19:48:08 srv03-lin sudo: root : TTY=unknown ; PWD=/ ; USER=root ; COMMAND=/usr/bin/x2gopgwrapper listsessionsroot srv03-lin Oct 4 19:48:13 srv03-lin sudo: root : TTY=unknown ; PWD=/ ; USER=root ; COMMAND=/usr/bin/x2gopgwrapper listsessionsroot srv03-lin Oct 4 19:48:18 srv03-lin sudo: root : TTY=unknown ; PWD=/ ; USER=root ; COMMAND=/usr/bin/x2gopgwrapper listsessionsroot srv03-lin Oct 4 19:48:23 srv03-lin sudo: root : TTY=unknown ; PWD=/ ; USER=root ; COMMAND=/usr/bin/x2gopgwrapper listsessionsroot srv03-lin "/etc/init.d/x2goserver stop" will stop the authentication requests. Any Ideas what can cause this? On the client side I experienced other strange things, when having multiple sessions I get this on the x2go web plugin client (browser iceweasel 3.5.12): (the command update-manager was lauchched within a gnome xterm shell) hoefle@srv03-lin:~$ sudo update-manager [sudo] password for hoefle: Wrong Password [sudo] password for hoefle: Sorry, try again.

I have a swiss-german keyboard layout and I have a key mismatch, it seem that I always get a german keylayout. Is eventually not every keymap implemented? Cheers, Marco
