Thanks for this Knud.

So, Mr. Donnie, with your default installation Slackware box, you certanly
won't get pop-up spam, but if your ftp server has a bug or SMTP server is
misconfigured (allowing relay), you might find various thing, *when* you log
in. Or with any other services which we can see there (finger, ident and oh
look portmapper).
Look how many services are started, *before* you login and while your
Slackware box is sitting at login prompt.

Conclusion? Every "modern" OS will by default start various services. It's
up to user to shut them down and disable them.

I don't see a reason on bashing WinXP for starting a RPC service
automatically when absolutely everything does that (don't mention obsolete
Oses please).
