Beyond the usual (HTTP, mail, DNS servers, etc), what is the average non-admin user going to set up that listens as a server? Admin-users setting up those traditional services ought to know how to manage firewalls, or they ought not to mess around with those services. Thanks to the forever moving target closed-source things like ICQ, MSN, Yahoo messenger (some of which have gone by the way of the dodo), there isn't much in the way of Linux-based clients for those kind of things that need to have listening ports. I can only think of something like bitorrent, which doesn't seem to need you to poke holes in your firewall. -- uname -rsvp Linux 3.10.0-1062.12.1.el7.x86_64 #1 SMP Tue Feb 4 23:02:59 UTC 2020 x86_64 Boilerplate: All unexpected mail to my mailbox is automatically deleted.
