In other words if I disable them will my system stop functioning? 111 sunrpc * close this. not needed 113 auth * identd authorization port. depending on whether you go on irc or not, you may want to keep this one open. 513 login * You can close this one (not needed for outide stuff) 514 shell * close this one too. 515 lpd * Unless you want to have people print to your printer from the outside network I'd close this I pretty much get the meaning of what each one is from the name except sunrpc. Do they need to have an open port for someone to function on a local host though? Are there any serious ramifications if I disabled them?
