Syncronizing time on 3 Linux 5.2 servers and a NT 4.0 server

Syncronizing time on 3 Linux 5.2 servers and a NT 4.0 server

Post by Joseph Kneppe » Sun, 31 Dec 1899 09:00:00



We have 3 Linux 5.2 Pent II servers using Samba to share files with a Dual
processor 500Mhz NT 4.0 domain controller server .  Each Linux server
Polls the out side world using the network, internet, and modems. The
poling is done at consistent time hacks every day 365 days a year on each
server.  The clocks drift constantly and eventually the times overlap and
ultimately one or all the servers break the Samba link or lock up a modem.
Thus, no more data until server(s) are rebooted. Is there a no-brainer way
to sync the time on these computers. I,m 7 years away from my Unix years
and a bit week in my Linux.  Kind of forced to make things happen "NOW"
and I'm not back up to par yet.

Look into xntpd, chrony, and Linux time tools generally:

http://www.eecis.udel.edu/~ntp/
http://www.linuxdoc.org/HOWTO/mini/Clock.html

I just configured xntpd on my network of three computers. I wouldn't say
it was a "no-brainer," but it was no worse than configuring most other
Linux daemons. You should probably set up one system to grab the time from
an external site, and configure the others to grab the time from the first
system. There are NTP client packages for most OSs, not just UNIX/Linux.
The first site I referenced has a sub-page that lists such clients for a
variety of OSs.
