Fedeora NTP server problem
|
|
|
| Hi I need some help with a NTP problem:
I installed Redhat Fedeora and set up an NTP service for the rest of the
network. I had been previously been using Redhat 9 which worked as it
should ising SNTP V4 on port 123 to syncronize the network time. Using the
same script in Fedora Core 1 I encountered a problem. I could not get the
other computers on the network to syncronize with this server. After some
invistigation i found a service on port 37 however the other computers on
the network will not syncronize with this service. The connect to the server
and go to the steps but do not change the system time. Other computers are
running Windows XP. I am using Automachron to syncronize.
Firstly, could someone explain why this service is offered on port 37 insead
of port 123...
Secondly, how can this problem be fixed?
Thanking all of you in advance
PEter

It's a different protocol. Port 37 is the RFC 868 time protocol:

1. See that the ntp daemon is installed, running and synchronized to
some external time source.
2. open port UDP/123 in the firewall for incoming traffic
3. edit the "restrict" rules in /etc/ntp.conf to allow other machines to
sync with your server.

Hi Peter,
You may want to post your issue at comp.protocols.time.ntp
and google is your friend.
