How many people use NFS on a news server? None that I am aware of. A PPro 200MHz can handle all the mail 3 T3's can dump on it. How much mail are we talking about? Storage may be an issue, but thats a whole different ball game. You can also use qmail to queue your jobs and spool them to a single repository for local deliveries. > I know that BSDI had some file locking issues..

I would think that the all the UFS info from the hosting partition (including locks) would be transmitted over NFS. I could be wrong though. > I should have defined my scares me to death more..

I know what you mean, though. You want a system you set up and NOT WORRY ABOUT. Our NFS server has had in excess of 250 days uptime, but I am not doing anything fancy on it. It is exporting NFS and samba, and I have not had ANY lockups, freezes, or corruptions so far (knock on wood!). > We also had some really nasty situations come up with BSDI 2.0 where we > would have to reboot the machine to make NFS work after clients crashing.. Yuck. That would be a definite problem. I still think you can avoid NFS if you want to. I also think FreeBSD's NFS kicks the shit out of Linux's for speed, reliability, and security. I give Kudos to the guys who have worked on it. Kevin
