Longer: For this you need something like Ntop, but that actually _understands_ what the protocol is supposed to "look, act, and feel." IOW, you'd have to build a protocol decoder for each type of protocol that you wanted to look for. Ntop might be close, but I don't know of anything that does exactly that.
log tcp any any -> $HOME_NET !110 -> (msg:"FTP login USER"; content:"USER "; ) log tcp any any -> $HOME_NET !110 -> (msg:"FTP login PASS"; content:"PASS "; )
Should be able to dectect incoming ftp logins.. !110 to disregard al that nice email popping... disregarding ircd ports for USER is also nice if your network hosts a ircd..
