Freezing during typing? This is definately NOT a problem with the file server. The PC that you are doing your work on is too slow to support your compiler and associated applications properly.

It could be a reverse DNS problem, but you have other problems to track down, from what I can tell... --- Andy To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
