Hi,
thanks for your new script, but I didn't get it working:
heikok@pc4027:~$ bash ./vglconnect -s -C -e "vglrun tseries" vglserver1
VirtualGL Client 64-bit v2.4 (Build 20150126)
vglclient is already running on this X display and accepting unencrypted
connections on port 4242.
Making preliminary SSH connection to find a free port on the server ...
Bad escape character 'vglrun tseries'.
[VGL] ERROR: The server does not appear to have VirtualGL 2.1 or later
[VGL] installed.
Ah, wait, after a bit of debugging:
heikok@pc4027:~$ bash ./vglconnect -s -e "vglrun tseries" -C vglserver1
-s and -e are vglconnect options, -C is an ssh option and will stop any
other vglconnect options. Since the order of options is so important, it
might be a good idea to add a debug line like
Runnging vglconnect with options '-s -e "vglrun tseries"' on
ssh command with options '-C vglserver1'
My attached version adds these debug-lines.
