And, if so, do you have any NFS mounted file systems on your PATH. If these two are true; it could be a problem there. I've found that with older cards, particularly slower 8-bit ISA cards, you need to set the NFS read/write parameters down to 1024 or things "hang." NFS doesn't actually hang, it's just that the NFS requests never get through because of packet-size issues.. so, it's doing a lot of re-requests that never get satisfied. Dropping the read/write sizes down allows the older card to handle things... Now, why is this an issue with 'su' - because it's looking down your PATH to see if there are any issues there when you 'su'. It's that look-up that touches the NFS mounted file systems; which in turn "tickles" the "hang." - Dave Rivers - To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
