First, thanks for your help. I can't use newgroup from my work, but obviously I have tryed networks commands such as netstat to see if some application was running on the same port as NTP. And the answer is not. I have a pretty light installation of Redhat, and no program is using that port. This second email was to know if I was on the good list, and no the answe is not so obvious. I have searched on the Internet, and only find the question with no solution. Thanks for helping.
