I can't confirm or deny anything broker-related, as I have never set it up, but: Did you install x2gobroker-agent? I got told this is a requirement to resume/suspend via a broker (but don't know specifics.)

Nevermind, your initial mail included all installed packages. x2gobroker-agent was one of them. Hum, I don't know. Maybe there's more work required to make it work, other than installing x2gobroker-agent. There's no information I can offer off-hand, though.

Hi Mike

I'm very happy to see your message !! I test it for 10 days and can't see the resume function working properly.

I connect on the broker with this command : x2goclient --borker-url=ssh://10.0.0.XXX/usr/bin/x2gobroker The server run xfce desktop

When I launch the command i Never see the box which permit to choose resum/supend/or create a new session.

Why ?

I use the nightly build on a 14.04 Ubuntu

Could anyone confim me that resuming/suspending a session is functionnal trough a broker ?

I can resume/suspend a session directly to a x2goserver but i can't with the broker.

Resume+Suspend works with the broker version in the nightly builds.

It requires x2gobroker-agent to be installed on X2Go Servers.

It requires a working x2gobroker <-> x2gobroker-agent setup.

It requires a running x2gocleansessions script on the X2Go Servers (which needs to be activated on non-Debian based installations of X2Go IIRC).

It requires agent-query-mode=SSH (or LOCAL) to be set in /etc/x2go/x2gobroker.conf, ... or broker-agent-query-mode=SSH (or LOCAL) to be set in invididual session profiles.

Regards, Mike

No problem for the delay ;-)

I'm happy for Mike's answer. He confirm that the resume function works, so I can continue to test x2gobroker.

For the moment, no budget is available :-[

This morning , the resume session works !!

• broker
  • x2gobroker-sessionprofiles.conf
    • host=HostName of the server (if I use IP the resume function did not work)
  • /etc/hosts fill with the name of the server
• server
  • /etc/hosts fill with the name of the broker
• client * /etc/hosts fill with the name of broker and server

Great !!

When I launch the command i Never see the box which permit to choose resum/supend/or create a new session. Why ? This hints at an incomplete setup of your broker. Installing the packages is not enough, there are a few commands like x2go-keygen and x2gobroker-pubkeyauthorizer that you will have to run manually, with the proper parameters for your setup in place.

Here are some hints where to look if you want to do it on your own:

man x2gobroker-pubkeyauthorizer

man x2gobroker-keygen

http://wiki.x2go.org/doku.php/wiki:advanced:x2gobroker:loadbalancing

Of course, as Mike#1 already pointed out, commercial support is available, if you have a budget for it. Expect an hourly rate of 110 EUR (+value added tax) and about 1-2 hours of work required to get things set up and explained to you.

Feel free to contact me off-list if you're interested in that. :-)

Why ?

Maybe because there is a package named "x2gobroker-ssh" providing
/usr/bin/x2gobroker-ssh. I presume you log into the session broker as
the user who also shall launch the session (and not as the
"x2gobroker" system user).

That x2gobroker-ssh binary is a wrapper that sets the correct
permissions (setuid x2gobroker for all members of the group
x2gobroker-users). Unfortunately, this "hack" is necessary when using
the SSH brokerage functionality in relation with the x2gobroker-agent.
