a2go-client for MAC
by Jarle Bjørgeengen 21 Sep '10

21 Sep '10

Hi, first, thank you for a nice application. I've been looking for a suitable free NX low-bandwidth solution and x2go seems to fit the purpose well. I'm using the MAC client, and I'm a bit puzzled that it is necessary to turn on remote connections (and hence open the X11 TCP port for listening) in order to locally display the desktop received over NX protocole (presumably tunneled over SSH) . So first you tunnel over SSH for security, and then it is required to open a potentially vulnerable service in order to display that picture ... ? When starting X programs (like XTERM) in OSX it seems that the default behavior is to communicate over a internal unix socket. Would it be possible to have x2goclient for mac using the same mechanism rather requiring the opening of unsafe services ? -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Best regards .~.

FYI: New community distro born
by Oliver Burger 19 Sep '10

19 Sep '10

Perhaps most of you already heard about the problems in which Mandriva has steered itself. Now I'm happy to announce, that out of the ashes of a dying Mandriva a new distro is born. Mageia is a community project without a commercial company involved. As packager of the German mandriva community I was building the x2go packages for Mandriva in the past and I will be building x2go packages for Mageia in the future.

Plugin updates over time
by Gerry Reno 17 Sep '10

17 Sep '10

What will be the policy regarding Plugin Updates over time? By that I mean will future versions of the plugin retain backward compatibility and work with existing installations of x2go? It seems the browsers are always pushing users to upgrade their plugins so they have the latest functionality and security fixes. But this can also mean that existing installations that work with the newer plugin versions could also need updating as well unless the plugin is always sure to be backward compatible. What is the x2go policy in regard to plugin updates and backward compatibility? Regards, Gerry

Plugin Sources?!
by Joerg Sawatzki 15 Sep '10

15 Sep '10

Hey, I know this question was on the list already a couple of months ago but I cannot find it anymore.... So once again: Where is the source of the browser plugin? And where's the source of the win32 client? I quickly browsed through the stuff at http://x2go.obviously-nice.de/deb - but I couldn't find what I am looking for. Thanks in advance, Jörg

x2goclient-cli don't terminates correctly?
by Thomas T. 15 Sep '10

15 Sep '10

Hi, I have noticed that x2goclient-cli doesn't close all "Childproceses" after I closed/terminated a session. If I try to use sound , can't get artsd running properly :/ , there will be 2 SSH connections left, else only one SSH connection. Example with --use-sound -no : ps -A -f During running session: admin 22945 22534 0 13:53 pts/0 00:00:00 /usr/bin/perl /usr/bin/x2goclient-cli --user oldpc --server 192.168.0.3 --use-sound no --port 22 --command gnome-session admin 22954 22945 0 13:53 pts/0 00:00:00 sh -c DISPLAY=:0 SSH_ASKPASS=/home/deka/.x2go/ssh/askpass setsid ssh -p 22 -N -L 30001:localhost:30001 oldpc(a)192.168.0.3 admin 22955 22954 0 13:53 ? 00:00:00 ssh -p 22 -N -L 30001:localhost:30001 oldpc(a)192.168.0.3 admin 22957 22945 0 13:53 pts/0 00:00:00 sh -c LD_LIBRARY_PATH=$X2GO_LIB nxproxy -S nx/nx,options=/home/deka/.x2go/S-oldpc-50-1284465225/options:50 2>>/home/deka/.x2go/S-oldpc-50- admin 22959 22957 0 13:53 pts/0 00:00:00 /usr/lib/x2go/nxproxy -S nx/nx,options=/home/deka/.x2go/S-oldpc-50-1284465225/options:50 After closing/terminating the session: admin 22955 1 0 13:53 ? 00:00:00 ssh -N -L 30001:localhost:30001 oldpc(a)192.168.0.3 Starting a new session brings me to bind: Address already in use channel_setup_fwd_listener: cannot listen to port: 30001 Could not request local forwarding and my System is collecting zombie ssh processes after several sessions ;) Is this a small Bug, got any else that Problem or is my fault aka messed up sys config? PS: No Problem with qt/gtk x2goclient but I forced to use the cli client and is there a chance for an pulseaudio update for x2goclient-cli? Sincerely, Thomas, Berlin 14.09.10

X2Go client occasionally loses mouse cursor
by John A. Sullivan III 15 Sep '10

15 Sep '10

Hello, all. We've seen this bug rarely but enough to know that it is a real bug and not just a coincidence. Here is the report from our internal trouble ticket. Unfortunately, it smells like it might be something in the NX libraries: The user called because she could not see her mouse cursor in her virtual desktop. It was visible in her physical desktop. As we later observed, it was indeed present in the virtual desktop, e.g., if she happened to stop the mouse over a file in Konqueror, it would display the thumbnail, but the mouse cursor was not visible. We tried suspending and reconnecting; that did not work. I could see where the mouse was supposed to be via my VNC session to her physical desktop so I tried to change the mouse cursor theme but that did not work (and required a restart of KDE). Finally, before rebooting to try to re-establish the connection between her physical and virtual desktops to display the mouse cursor, we thought to suspend her X2Go session and then completely close her X2Go client. When she restarted the client and reconnected to her X2Go session, the mouse had re-appeared. We did not need to reboot the physical computer.

Local Port for NXPROXY - no listen socket
by Stefan Bauer 09 Sep '10

09 Sep '10

Morning, i investigated the problem "debian lenny x2goserver-one - remote NX proxy closed the connection" a little further: Sep 9 09:38:13 x2go sudo: toni : TTY=unknown ; PWD=/home/toni ; USER=root ; COMMAND=/usr/bin/x2gopgwrapper createsession 82c97d9dce4c8f5ba52c8d98f4d560ca 7016 192.168.0.16 30031 30032 30033 toni-60-1284017892_stRxterm_dp32 According to x2gowrapper it is dumping gr_port='$5',sound_port='$6',fs_port='$7' so 30031,30032,30033 to sqlite. Anyway what is expected to run on these ports and how are they assigned? Everytime i try a connect, they are just increased. Sep 9 09:38:14 x2go sshd[7026]: error: connect_to localhost port 30031: failed. This is expected, as nothing is listening on these ports: x2go:/var/mail# tcpdump -i lo tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on lo, link-type EN10MB (Ethernet), capture size 96 bytes 09:38:14.446881 IP localhost.60169 > localhost.30031: S 09:38:14.447767 IP localhost.30031 > localhost.60169: R 09:38:14.447860 IP6 localhost.32904 > localhost.30031: S 09:38:14.448022 IP6 localhost.30031 > localhost.32904: R so it tries to connect to port 30031 first by ipv4 then ipv6 but nothing is listening on this port hence the R flag -> reset.
