[shifter-users] NoMachine NX server 3.4.0 doesn't like names with spaces

[Rohan Hart]

To make the free NX server from noMachine work with Shifter 0.10.0 I
had to edit nx_server_util.py and remove the space after the colon in
the name, like so...

name = "%s:%s" % (session.user, session.name)

With the space nxagent was throwing an - Error: Aborting session with
'Unrecognized option: xxxxx' - where xxxxx is the session name.

cheers
