Hi - I'm relatively new to the world of X, and I was wondering if someone could help me with a problem. I am working on an IPC and I would like to be able to launch, say the stock XVIEW texteditor, on a SPARCstation 2 and have the display show up on my IPC. A friend of mine told me to rlogin to the SS2, change the DISPLAY env. variable to aspen:0.0, and then launch the app in the background. I tried this, but got a library error that complained that it couldn't find lib.so.3( or some such library. i don't 'zactly recall... ). Any ideas? Thanks-in-advance, Paul E.

Hi again. I'd like to thank everyone for their suggestions and tips wrt launching remote X applications. It seems, that my problem was specifically the LD_LIBRARY_PATH environment variable. I will cover the entire procedure below for those other newcomers like myself. setenv OPENWINHOME /usr/openwin setenv FONTPATH $OPENWINHOME/lib/fonts setenv HELPPATH $OPENWINHOME/lib/help setenv LD_LIBRARY_PATH $OPENWINHOME/lib:/usr/lib setenv MANPATH $OPENWINHOME/share/man:/usr/man when you rlogin or rsh, set the DISPLAY env var thusly: setenv DISPLAY "you host name":0.0 Scott Brim <swb@MITCHELL.CIT.CORNELL.EDU> gave me the following script which he calls rx: --------------------------------- #!/bin/sh - host=$1 ; shift case $DISPLAY in :0|:0.0|unix:0|unix:0.0) xhost $host >/dev/null ; DISPLAY=`hostname`:0 esac rsh -n $host "sh -c 'DISPLAY=$DISPLAY $@ >/dev/null 2>&1&'" ---------------------------------- I haven't tried it yet, so I can't tell you if it works, but Scott seems like a nice guy...:-) He says that his officemate has a more complicated one. Again, thanks to all that have replied. It has been an uplifting experience. Paul E. Ourada Software Engineer Ohmeda Monitoring Systems paulo@ohmeda.com

Yeah, wouldn't that be nice. But it is not always available. Our management here says that on(1C) is a serious security risk and refuses to activate the necessary demon. So I am stuck with a shell script that sets up everything on the far end. -- --------------- uunet!tdatirv!sarima (Stanley Friesen)
