Modifying /etc/rc.d/ntpd in this manner did not fix the problem. I
still have 2 ntpd processes running indefinitely after bootup of the
system, until I manually issue a "/etc/rc.d/ntpd restart", after which
the ntpd runs fine. As a separate test, I tried adjusting my
resolv.conf to point to an external name server, and I disabled named
at startup, and used the original /etc/rc.d/ntpd. I still got the
same problem - 2 ntpd processes running indefinitely.
Does anyone know why I'm getting 2 ntpd processes running after bootup
(and ntpd fails to adjust the clock as a result)? Any suggested fix
would be appreciated.
