While getting perl to hop around our network and do a "uname -a" on each machine, I run into the problem that either a machine O/S is being re-installed, in which case the machine will return from a ping request (how I determine which machines to rsh on to) but when I rsh on to it, it slows the script down massively, since I have to wait until rsh exits, (ages) and worse still, some machines refuse a connection, and it bombs out the perl script completely. I'm wondering if anyone has come across this kind of thing before, or has written a script to report on O/S type (UNIX only) od machines on a network? I'd say it would be easy if rsh had a timeout switch, but it doesn't :-( Thanks, David FitzGerald.
