There appear to be a number of efforts involving developing python scripts for x2go.
What are the status of these python efforts? Did Jörg abandon his effort? Mike, you mentioned the you were redeveloping Jörg's scripts. Is that effort finished?
And what ssh connection approach is being taken with python scripts? Multiple ssh connections the same as the perl scripts? Or establish and reuse a single ssh connection?
And what is the minimum python level necessary to run these python scripts? 2.3, 2.4, 2.5, 2.6?
Just trying to gauge the requirements, features and maturity of the python efforts.
Regards, Gerry
Hi Gerry,
thanks for asking your questions.

Yes, Jörgs approach was initially licensed as GPL, but his contractor
refused to grant publication under an open license.
Mike, you mentioned the you were redeveloping Jörg's scripts.
Yes, I have rewritten Jörgs ideas and expanded the possibilities:
- pulse audio support
- local folder sharing
- printing (work in progress)
Is that effort finished?
No, that will probably take a great little while more. Dick Kniep from
Lindix in the Netherlands writes a GUI around the new Python X2go
library, whereas I will support his effort by co-developing the Python
X2go module.
I myself use my pyhoca-cli intensively (from the command line) and I
am very satisfied with its stability (on Ubuntu lucid).
The collaboration with Dick will hopefully bring forth:
o a GUI based client (wxPython) that operates form the systray in Windows /
as a docking applet in Linux (GNOME/KDE), one main objective is
multi-session support. Dick also plans a MacOS X version, but I
am not sure
how that will integrate in the Mac desktop (not familiar with terminology)
o handling of x2goclient config files (printing, settings)
o handling session profiles in ~/.x2goclient/sessions
I will also later add LDAP support... In fact, there is still a bunch
of work to do...
And what ssh connection approach is being taken with python scripts?
Python X2go uses the Python Paramiko SSH implementation.
Multiple ssh connections the same as the perl scripts? Or establish and reuse a single ssh connection?
Python X2go builds up one SSH Transport connection. Through this
connection all tunnels (nxproxy, audio, local sharing, printing) are
handled. I have implemented its own SFTP server into Python X2go. This
means: Python X2go does not need a local SSH daemon. Python X2go uses
its own SFTP implementation (works great for me).
And what is the minimum python level necessary to run these python
scripts? 2.3, 2.4, 2.5, 2.6?
You need Python2.6 with Greenlet/Gevent module. I have prepared
packages for Ubuntu lucid/maverick and Debian squeeze/sid in our
DAS-NETZWERKTEAM repository.
Just trying to gauge the requirements, features and maturity of the
python efforts.
Please refer to our project homepage, SVN and the Epydoc-generated API
documentation:
Greets, Mike
PS: currently I am working on a completely different project, which
will last another week at least. Once that is done, I will return to
Python X2go development.

Damn, typo here: ... Jörgs approach was initially licensed as _Lesser_GPL...
My Python X2go rewrite, though, is GPLv3.

Thanks Mike. That all sounds great. Paramiko certainly looks like a good choice.
Python 2.6 might limit somewhat. I'll have to see how far back in distros we could possibly go using 2.6.
When I get some time here I'll start playing around with these scripts.
If at all possible I would prefer to use python over perl. Better
performance and little nicer syntax.

Any form of testing is welcome. Dick focusses on Windows and MAC
compatibility, I guess he will thankful for any form of help with
that, as well.
