Is there any distribution this actually works on? :D

I have just checked packages.x2go.org and quickly built the missing python-pampy for the main repos area. (They had already been built for the heuler area).

python-pampy is now available. Please try again and report back if it works now.

Btw.: the session broker is quite recent code and has a very small user base still. It could be professionalized by sponsoring projects.

Hi Mike,

the installation works now, thanks! I left most of the configuration at defaults but changed to iniconf and enabled debug mode. Following the instructions to browse http://IP:80/x2gobroker/plain/iniconf shows this HTML:

<html><title>404: Not Found</title><body>404: Not Found</body></html>

In the meantime, apache shows this

It's a bit confusing to see "X2GOBROKER_DEBUG: False" and then "if unwanted: disable X2GOBROKER_DEBUG". First line makes me think debug is not enabled, second says it is. But the real problem for now is that I expected to see the contents /etc/x2go/broker/x2gobroker-sessionprofiles.conf but saw 404 instead.

Wrong expectations, or misconfiguration? :D

Ok, next round. python-wsgilog is now available through wheezy/main on packages.x2go.org.

Hi Mike,

I am getting closer to a working setup :) Adding the parameters, of course, helped. The Wiki doesn't tell about these so I am going to add that later on. About the parameters though:

=> Access granted.

http://***.***.***.***/x2gobroker/plain/inifile?user=mathias&password=**********&task=listsessions

x2goclient --broker-url=http://***.***.***.***/x2gobroker/plain/inifile

Shows me a login screen but then says login failed with the same error messages on the server as above.

About the nightly builds: I need to get this working quickly. Once that is done I will play with the nightly.

Wrong expectations, or misconfiguration? :D First, you have to give some parameters:

<URL>?user=<user>&password=<pw>&task=listsessions

If that is not somewhere in the wiki, then please add that piece of information. Thanks

Then, you should really try out the version from the nightly builds which I am about to release (0.0.3.0). It would be cool if you could play with that one, because the we can get some more fixes into 0.0.3.0.

Hi again,

I cannot find any documentation on the x2goclient session files - parameters, values etc. Is there any? I need this for the x2gobroke configration file as the params seem to be the same and here is what I would like to configure:

• SSH proxy with username and password same as those authenticated against the broker with
• username and password already integrated into session information so no further auth necessary

Is there a way to do it?

cheers Mathias

Hi everyone,

looking at http://wiki.x2go.org/doku.php/wiki:development:sessions-file I figure x2go can tunnel RDP connections via SSH proxy, too. Is that true? Because trying this configuration

[20131009111725764] speed=2 pack=16m-jpeg quality=9 fstunnel=true export= iconvto=UTF-8 iconvfrom=ISO8859-1 useiconv=false fullscreen=false multidisp=false display=1 maxdim=false rdpclient=rdesktop directrdpsettings= width=800 height=600 dpi=86 setdpi=true xinerama=false usekbd=true layout=us type=pc105/us sound=true soundsystem=pulse startsoundsystem=true soundtunnel=true defsndport=true sndport=4713 print=true name=windows rdp test icon=:icons/128x128/x2gosession.png host=**************** user=********* key= rdpport=3389 sshport=22 autologin=false krblogin=false directrdp=false rootless=false published=false applications=WWWBROWSER, MAILCLIENT, OFFICE, TERMINAL command=RDP rdpoptions= rdpserver=10.173.20.13 xdmcpserver=localhost usesshproxy=true sshproxytype=SSH sshproxyuser=mathias sshproxykeyfile= sshproxyhost=**************** sshproxyport=22 sshproxysamepass=false sshproxysameuser=false sshproxyautologin=false

x2goclient says "cannot connect to 10.173.20.13:22" and "Timeout connecting to 127.0.0.1". So it looks like it is trying to use the tunnel (127.0.0.1) but tries to SSH to 10.173.20.13 instead of RDP.

Any Ideas?

cheers Mathias

Hi Mike,

I can start XFCE4 sessions through the proxy without any issues.

X2Go indeed support proxied X2Go connections. However, I have the suspicion that the SSH proxy feature that you try to use is currently (4.0.1.1) broken in X2Go Client.

Does the SSH proxy setup work with normal desktop sessions (say LXDE or so) for you?

I have tested several of my session profiles that work fine with PyHoca-GUI with X2Go Client and I also get these connection timeouts.
