If you can get to a shell, just do this (you need to be root): # chkconfig --level 0123456 ntpd off Check that it is disabled at boot: # chkconfig --list | grep ntpd ntpd 0:off 1:off 2:off 3:off 4:off 5:off 6:off 2. Next, you boot the system and see if it comes up. Sometimes ntpd fails because the default port that the NTP server you are trying to synchronize with is blocked, and you will need to use unprivileged ports. You can check if this is the case with the following command: # /usr/sbin/ntpdate <server_name> If it seems to hang up, just hit <Ctrl>+C, then try this: # /usr/sbin/ntpdate -u <server_name> This tells ntpdate to use unprivileged ports instead. If you get a reply, that means that the problem is likely to be the firewall on the NTP server's end. NTP listens on UDP port 123 by default. Unfortunately, for FC1 to FC3 (I think), the ntpd script uses the default port instead of specifying the use of unprivileged ports.
