Initiating a remote X session

[Steve Howie <showie at uoguelph dot ca>]

Howdy,

We've just had a look at cygwin-xfree and are very impressed. However, 
we'd like to bundle it for our users so that we have a some pre-defined 
'sessions' available e.g. connect to a Unix host, run SAS then have the 
output sent to an cygwin-xfree server. Unix commands are not the forte 
of most of our users.

This is fine with a static IP address  - we would launch a program which 
does something like:

rexec <host> -l <username> "setenv DISPLAY <ipaddress>; /opt/SAS82/sas "

from the Cygwin shell. All bets are off, however, since most of our IP 
addresses are served out by DHCP.

We currently use X-Win32 which has a nifty feature for getting around 
this - you can specify $MYIP:0 which picks up the current IP address of 
the X-server and passes it to the session definition which is sent to 
the host which will run the application.

So ideally we would like something similar to this in cygwin-xfree :

rexec <host> -l <username> "setenv DISPLAY $MYIP:0; /opt/SAS82/sas"

I did a quick dig through the archives and noticed something similar to 
this question - but it was from a while ago - we'd ideally like to have 
the user get a popup prompting them for a username/password for the 
host, then pass this information via a command such as the one above, 
and also pick up the X-servers IP address whether static or dynamic. Is 
something like this available already?

Any info would be appreciated!

Thanks,

Scotty
