Re: [CentOS] NTP server

I have a Centos 5 64-bit server that has ntp service enabled. Windows XP with SP2 cannot properly sync to it for time, but can communicate with it via samba, ssh, and anything else. I also disabled the Windows Firewall. The C5 system does not have any firewall enabled.

The following would stop this:

1) DNS with a fully qualified name. 2) CentOS-5 server does not have port 123 open on its firewall iptables -nxvL | grep 123

should give you an answer to that 3) CentOS-5 server is not serving NTP to your network

netstat -nalp | grep :123

should have something other than udp 0 0 127.0.0.1:123 0.0.0.0:*

This is configured in the /etc/ntp.conf file.
