Thanks, Jim. I'm not in the US, and it's going to be quite a long while before we have a holiday .... and no prizes for guessing what I'll be doing while some individuals on this list are going to be drinking beers and munching hotdogs ;)
B.T.W. I forgot to mention the /etc/securetty file. I wonder if that's what is causing it? This file looks like it is used to restrict root logins, but I am not sure how it's logic works, or whether I need to send a SIGHUP to some bloomin' daemon after editing it. The file contains a list terminal devices, so probably these are the terminals it (accepts?) root logins from. Interestingly, the /etc/securetty file on my RH 7.1 server contains tty1 thru to 8, but I can still use PuTTY to access it remotely. As per usual, this server was set up by someone else, and it's our (my) job to administer it.
