This is my first post so sorry if I don't make any sense this time round. We have a SCO UNIX server that produced the following list of errors (among others) when doing backup with tar: tar: dev/inet/tcp is not a file, symlink or directory not dumped. tar: dev/inet/udp is not a file, symlink or directory not dumped. tar: dev/inet/cfg is not a file, symlink or directory not dumped. Also about two weeks ago, users connecting to the server using remote terminals couldn't log in using the root password so the server had to be rebooted before it allowed root to log in again. I have never used SCO Unix, or tried any administration on a Unix server before, so I have no idea what/where I need to check to start troubleshooting the server. Please help...anyone...?
