ntp server: mulitiple interfaces

[Joel Hammer]

I have xntp set up on a gateway box and it synchronizes well with some
network time servers. I want to use this box to synchronize my home network.

I can't get my other boxes to see the time server daemon on the gateway
box. This could  be explained if the daemon (xntp) was only listening
to one of the two NIC's in the gateway. Using nmap, I don't see any open
port 123, so, this is possible, I suppose. I have not found any
configuration item which tells the daemon which NIC to listen to.

Oh yes. What is the difference between xntp and ntp ?

Any suggestions welcome,

Joel
