>I've seen this many times; if you don't properly umount the nfs stuff and >a machine disappears, it's hell to get them talking again. The thing is, I don't think it's just NFS related. I think it's TCP related -- specifically, the problem seemed to be when the rebooted machine tried to establish a connection to the non-rebooted machine, where the new <src addr, src port>:<dst addr, dst port> matched the old ones. This is not quite right behaviour -- for the rlogin I tried, the non-rebooted machine should have realized that the connection was gone. Or I think it should have, anyway :). This affected me with NFS, because I am using TCP for NFS -- and there was no way (that I could see) to cause the connection to be closed on the non-rebooted machine. (For the rlogin, I did a 'kill -HUP' of the shell on the defunct connection; that caused the connection to finally close, which meant I could log in again.) Sean.
