[Gllug] xntp strangeness

Hi all,

I've been trying to get ntp to work properly over my local network. I have a 
server which picks up the time from an external public second strata time 
server at boot. All the client boxes then pick up time from the local server 
when they boot. So far so good.

Tonight, I wanted to shift the local time server onto my gateway machine, 
because it seems more logical to have it there than on an internal server. 
Anyway, I have failed miserably....

I am hitting a wall which has taken me a couple of hours to identify:

The server picks up the time with no problem. And before today there were no 
problems internally picking up the time from the local server. I changed the 
server specification on the gateway to point to the external source and 
issued an rcxntpd restart (I'm using SuSE8.2, btw) and all was fine. Then 
changed the config on the former server to point at the gateway instead of 
the external source. An rcxntpd restart on the server led to a failure to 
pick up the time from the gateway.

Much playing later had led me to the following state: If the machine serving 
local time is rebooted, all clients can pick up the time from that server, 
but if the server undergoes an rcxntpd restart then the clients can no longer 
pick up the time.

I'm at a loss...

Dylan
