You might want to check out the "sudo" utility, which is a very flexible way of letting users run programs as other users, in a nicely controlled fashion. http://www.courtesan.com/sudo/ It's complicated-ish, but very powerful. I'm no super-hacker, and it took me only a couple of hours (maybe an afternoon at most) to understand it sufficiently to allow one particular user to run one particular script as root, ie it's worth persevering with despite initially looking hard. Of course, there are other ways of doing the same thing, but I think this is a particularly nice one. :-) -Andy -- Andy Gimblett - Programmer - Frontier Internet Services Limited Tel: 029 20 820 044 Fax: 029 20 820 035 http://www.frontier.net.uk/ Statements made are at all times subject to Frontier's Terms and Conditions of Business, which are available upon request.
