Hi, Managers!
I have to post a 2nd summary. The echo to the summary was very
much better in quality and quantity. I assume, many people are only
reading mails with summaries 8-).
The best way for me is to use getpeername in a little c-program.
See the mail from Harish below.
Other suggested perl-scripts.
I have only included the c-source, I will use. If anybody wants to get
the whole stuff, please send me a mail, lets save resources!
Thanxs to all below, Thomas
BTW: Sun-Managers ist the most helpful list I know !

"SUMMARY: rsh, which host is calling me ?" (Oct 17, 10:52am)
To: bl@gfz-potsdam.de (Thomas Bleek)
Thomas,
A small 'c ' code which i am appending to my mail might help you out.
We use this executable to bascially set the display variable for a PC
from which an unix application is invoked via rsh/rexec.
This executable "whoru", figures out which PC is calling it and
based on the IPAddress/hostname, which it derives, sets the DISPLAY variable.
This works only for PC's and not workstations (we didn't had the time
to get to that part yet) may be you can hack the script on those lines
and come up with what you want.
Good Luck.
HarisH
