Can any one explain quickly how redhat configures its FTP server. I want to allow a user called ftpuser to ftp in but it wont let me. What do I need to edit?

OK, how? It's bound to be less than 650Mb of compressed packages... Bandwidth isn't a major problem, but wasting CDs and time is. -- MJR

Make sure that the outside world can't access nfs on the machines. Whether you do this with ipchains/iptables or try to use hosts.deny to limit it is up to you. That's the main thing to bear in mind. -- MJR

Its a 386 Raq4 Actually a good machine in general. I beleive the OS is based on Red-Hat 6.2 from what I can tell. RPM is installed but only for addit stuff. Patches etc must be via the pkg program. I haven't used it directly, there is a page in the admin interface from where you can install via an ftp URL. This is a bit of a pain because I have to run the Admin Interface via SSL which slows things a little.

Argggggggh to you too ! ;o) The Machine in question is a cobalt and unfortunately they're slightly later than most with updates. Actually I fully agree with you. I have an little script which daily checks the update site. (though I only have it advising me if there is a change, I haven't worked out how to get the updates automatically by script...if anyone has played with a cobalt you'll know that there is only one route for applying patches. If you're a bit of a wiz with scripts though I'd be glad to get some info off you. Cheers Earl
