Yeah, I've been pushing the setcap command for people since I moved to Linux.

Something people reading this considering using setcap to run ports on the
currently logged in user and privileged ports: once you upgrade your mis
executable (or any other with setcap) you'll have to set it again on the new
executable.

I get around this by invoking MIS and a bunch of other stuff on startup with
a bash script, so I also plopped the setcap command in there as well just so
I don't have to remember to do it again after upgrading.

And since you might have to use sudo to run it, and it won't run without
prompting normally, you can get around it with this (not really secure since
you store your system pw in a text file):

echo "your system pw here" | sudo -S setcap 'cap_net_bind_service=+ep'
