Apparently I don't receive all emails from this list - this is a problem we
have on our LAN: some mails get dropped.
thanks for your help - unfortunately it doesn't solve my problem. I just
installed SuSE 8 on a new server, and it behaves in the same way, so it's
not just RedHat.
I checked /etc/ntp.conf for anything like 'restrict ...', but there is
nothing; am I looking in the right place?
Also, I haven't got ipchains, but it turns out that iptables is installed.
However, there doesn't seem to be any restrictions on ports in place.
Maybe I'm just clueless; though I have worked with computers for >25 years.
But perhaps this is the problem ;-)
