Hi I want to deny telnet, ftp and smtp connection from ANY other sites. But I want to accept http connection, pull down pop3, imap and send out mail (smtp). How do I setup /etc/host.deny, /etc/host.allow and CO. I will RTFM but since security is so important (that why I choose Debian) I'd like to hear all the tips, tricks and know all traps, pitfalls... Thank you -- Linh Dang
