Can somebody point me to a good, recent guide on securing my Slackware 8.1 box?
I use this machine as a gateway/firewall/web server/ftp server. So there are obviouslly many security issues with a machine so open.
I want to set up a mail server as well, and installed UW IMAP but ran into problems with error 550 - relaying denied. I think I have decided that before I go any further trying to enable my mail server I want to really audit my system and ensure it is secure as possible. The last thing I want is to become a mass-mailer for somebody and get black listed.
My problem is that most of the guides on securing are centered around RPM based distro's - and the only Slackware specific guides I can find are very old.
Any links you could provide, or even advice on security issues I should be concerned with would be a huge help.
Thanks a lot for your time
