Hi,
Well, the good news is I haven't made inetd fail... The bad news
is that by default the SIGCHLD, SIGHUP and, SIGALRM signals are now
being blocked when the fork()/exec() calls are made.
So... The child process does not receive these signals by default
anymore. This is major behavior modification and definitely causes
some very interesting side effects... :-) Love them Zombies!
We still need to unblock the signals in the child process after
the fork... The following should do the trick:
--- inetd.c.orig Mon Dec 14 02:07:34 1998
+++ inetd.c Tue Dec 15 17:20:02 1998

Hey! As always comments, critiques, and hints are most welcome...
Thanks!
John
