Oopps! One of the mail links didn't like the lines with only a dot (yes,
I speek a little of smtp), so here is my last message, I hope with the
interesting part included in it:

And here it is:
I don't know tcp-wrapper, but:
a) so many daemons (init, inetd, etc) use SIGHUP to re-read their
configuration files. So kill -HUP `cat /var/run/syslog.pid` isn't kill
it, only send an alert: ``Read your files, something was changed!''
b) I think, tcpd makes it's pid file like this:
------------------------------------+
v
open( PIDFILE, O_RDWR | O_CREAT | O_EXCL );
And because with kill -9, he/she/it hasn't any time to remove it, at next
start, exiting. Try kill -9, remove /var/run/syslog.pid, and start it over.
If it exits, sorry.
