Hi Sun Admins,

may i know is it possible to synchronize time using ntpdate b/w two
ntpservers ?

the problem is that our servers are unable to synchronize with our ntp
server as its behind the firewall.

As far as i know, ntpdate uses port 123 UDP to connect to ntp Server

the source port used by the client is choose randomnly >1023.

so ntp server reply to ntp client request to that randomnly choose
port.

The problem is that we have bidirectional firewall. and they wont open
firewall for randomn ports.

the destination port should be specified or the range of ports should
be
specified.

Do you know what range of ports will be used by ntp client when
connect to
the ntp server.

As a workaround i decide to run ntpserver on my ntpclient. so in that
case
the both source & destination ports will be 123.

So i want to know if it is possible to synchronise my Server if
installed
ntpserver on it and then it get sync with remote ntp server.

2ndly what is the range of ports ntp client use to sync with ntp
server.

I hope i clearly describe my problem.

Appreciate your expert inputs.
