Is there anything going on when you get hung up? cron is actually not running on the system at the moment, I turned it off because mail wasnt set up at the time and I havent gotten around to turning it back on > > Last but not least, are you on a switch?

The file server and cpu/auth server are connected through my hub (thus avoiding the switch). The terminal is in a different room and therefore, does use the switch. However according to the resident networking guru, the hub should be transparent so long as ieee standards for ethernet and arp are maintained regardless of half or full duplex.. > > If a cache file system helps, it will be because you're side stepping > the real problem and it'll come back and bit you in the backside. > i figured a cache would only avoid the problem for a while, however i was thinking that maybe if all file access doesnt go away the system may be able to reconnect... The last time i made this happen i was connected through 2 ssh links, telnet, ftp and a drawterm. Im pretty baffled by this one.

It installed from the internet, the file server was populated with the contents of the iso that came with the installation, once the file server was filled I disconnected the drive and rebooted the standalone system as the auth server.
