Maybe I need to find a way to bump up .1's advertised > stratum? That's it, precisely. You need to tell .1 to consider *itself* a stratum 10 time source. You do this as follows: server 127.127.1.1 fudge 127.127.1.1 stratum 10 (The number 127.127.1.1 is magic. It means "use the system clock". Don't think of it as an IP address; pinging it will not work.) After a few minutes, this box should advertise itself as a stratum 10 server when you ntptrace. At that point, the "client" (.2) box can run "ntpdate 192.168.1.1" and ntp can maintain synchronization. aphro (nate@firetrail.com) wrote: > [root@aphro ~] telnet galactica 123 > Trying 208.222.179.31... > telnet: Unable to connect to remote host: Connection refused That's because ntp uses UDP, not TCP. Telnet is a TCP/IP application. If you want to "connect" to a UDP port, look into netcat. -- Greg Wooledge | "Truth belongs to everybody." wooledge@kellnet.com | Red Hot Chili Peppers, http://www.kellnet.com/wooledge/ |
