Hello,

How to synchronize a NTP client (Linux) with a server running w32time (Win 2000)?
I tried a lot of times and each time I have the same error:
"no server suitable for synchronization found" and "Server dropped: strata too high".
My Win 2000 is not synchronized with "the real time" but I would like to use it as a time server for the others machine.
Other Windows station can synchronize on the Win 2000 server but not the Linux NTP client.
After a lot of tests, I installed YATS (Yet Another Time Server) and I was able to synchronize Linux on this Windows.
The problem is that YATS is not free and it expires in few days.
I can't use an other NTP server because the port is blocked by the firewall.

Is it possible to synchronize an NTP client with a server running w32time?
I read somewhere that w32time on Windows is a SNTP server and not a real NTP.
Is it possible to sync a Linux NTP client on a SNTP server?
Does a Linux SNTP client exist?

Thank for your help.
