[ILUG] Identifying telnet connections?

[Tony_Melia at Dell.com]

I tried export DISPLAY=`who -m | cut -f1 -d'!'` this seems to set the
display address to the server rather than the client....

I finally got it working by using

DISPLAY=`who -m | cut -f2 -d'(' | cut -f1 -d ')'`:0

Thanx to Sean...

Tony.

  this works for me:

     export DISPLAY=`who -m | cut -f1 -d'!'`

  though it's linux 'who' specific
