Thanks for the reply- This is on Planet-Lab OS (http://www.planet-lab.org) where NTP is already configured, but I need to run my own NTP client for an experiment. I have the root access to my slice, but since port 123 is alreadyin use, I am facing this problem.
I was wondering if I can configure my machine for just NTP client and not the server, this way I can bypass the bind() operation. I know openntpd permits this but I think it does not change the rate of the clock( that's what I have read) Regards JS On 2/15/06, Richard B.
