Package: pyhoca-cli

Version: 0.4.0.3

I'm attempting to launch an XDMCP session that is suspendable and transferable from one workstation to another. My setup has two workstations each of which can connect to a "session-server", which in turn does an xdmcp query to a host I'll call "xserver". Note that the xserver in this setup is an old solaris machine that runs X, but doesn't have the x2go server packages installed.

Here's my ascii diagram of what I tried to convey above:

workstation1/workstation2 (x2goclient, pyhoca-gui and pyhoca-cli installed)  ->   session-server (x2goserver installed)  ->  xserver (xdmcp enabled)

I set up a session using "pyhoca-gui", which results in the following:

------------------------------

When I use x2goclient, I'm able to launch the session, suspend the session, and transfer the session between workstations as expected.

When I use pyhoca-cli to create the session, I get the following results:

% pyhoca-cli --server session-server -N -P pyhoca-xdmcp

I'll note here that this also doesn't work with pyhoca-gui (I'm sure I'm supposed to write this up separately, but I think it's useful to have all this information together in one place):

% pyhoca-gui

pyhoca-gui[16667] (PyHoca-GUI) NOTICE: [pyhoca-xdmcp - session failure] The session startup failed.

Finally, I will note that if the session is created by x2goclient, then suspended, both pyhoca-gui and pyhoca-cli can successfully resume the session created by the x2goclient.

Here are the versions I'm running:

pyhoca-gui --version
