Synchronation between windows 2k and redhat linux

Synchronation between windows 2k and redhat linux

[Miguel González Castaños]

Dear all,

 I have two linux servers in a LAN with a windows 2K domain.

 Due to a web application for booking facilities, we have suffered the
problems of having different times in our linux servers and in the
domain.

 As all our workstations get the net time from the PDC through SNTP, I
thought about the same from the linux servers. Because I didnt know
anything NTP, I had a look on the Internet to see some newsgroups and
webpages, but I didnt get the idea of how to sort this out.

 I installed the ntp client on one of my linux servers but obviously,
because We have SNTP and not NTP there is no possible connection. I
thought of just set the time of those linux servers on the respective
BIOSes, but I am trying first a more professional approach. Maybe I
should rethink the scenario and try other approaches: such as
synchronizing the PDC with my linux boxes...

 I just want to get any idea from you guys...

 Many thanks

 Miguel

Hi,

 Thanks for your promptly answer.

 I am considering that possibility, but I didnt want to bother the Windows
admin. I have
read some about rdate, but is it reliable and secure? I read some comments not
recommending it...
 Which approach would be better? To sync the PDC with any of my linux boxes or
use rdate?

 Many thanks

 Miguel

I don't believe that rdate is either. Then again I haven't come accross
security as being a mojor concern of any time clients...

I'm not sure to be honest.  If you don't need seriously accurate time (ntp
levels of accuracy) then I wouldn't have thought there would be a big
difference either way.  Having said that I'm not sure how Win2K ADS reacts
to the system clock (potentially) going backwards after a sync.

cheers
