Hello Dear Friends, it is CentOS Release 6.2, ntpd is running but do not see bounded to the port udp:123 any guidelines would be very much appreciable. [root at jet mavi]# netstat -ntlp | grep ntpd <nothing in output> [root at jet mavi]# netstat -ntl | grep 123 <nothing in output> But the service is running - [root at jet mavi]# /etc/init.d/ntpd status ntpd (pid 15876) is running... Selinux is disabled Thanks / regards
