If you try compiling code across NFS mounts it is imperative to have the peers in sync. I see no reason not to have the peers in sync with the correct time. What I do is have one FreeBSD machine use xntp to sync with a stratum 2 ntp server and then all other machines sync with this machine on the LAN. I then have all the Unix, Windows, and Mac machines in sync, using whatever method is required for the respective platforms, to get the time from my "time" machine. -- Glenn Johnson gljohns@bellsouth.net To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
