Thanks for this, but unless I actually use ssh (or anything else) surely it's best to remove it? I don't log in to remote machines, except for logging in to various web pages from time to time. Unless ssh does something in the background while I am doing this, or while I am downloading stuff from such sites, (please put me right if it *does* do this - I'm still slightly unsure) I'd simply rather not leave it lying around. But your email is filed away in case I do start using it, so thanks again. Cheers, Geoff -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
