I have a newly installed Centos 5.2 box, everything seems working except ntpdate sync, I have done enable port 123 UDP to pass through the firewall. I have tried to use -u for unprivileged ports but still keeps throwing this error "no server suitable for synchronization found". Can anyone there help?
Do you have a NTP server configured? ntpdate will display that error message if you don't have one... try
for starters.
You could try to sync with an internal NTP server to sort out firewall problems (every Windoze Domain Controller is also an NTP server, or install
ntpd
usingyum
).
