erm....don't diasble them in /etc/services, this normally doesn't work (as
far as I'm aware). /etc/services is more a 'lookup' service then a 'whether
I should actually work' service.
according to /etc/serices 111 is 'portmapper', darned if I know what it
actually does however you may find it lurking in your /etc/(x)inetd.conf or
even /etc/init.d/<something, likely to be 'portmapper'>. Type
"/etc/init.d/<whatever> stop" and then do another netstat and see if that
helps.
As for the 859 I cannot see where you got it from, no reference to it at all,
from what you have given us. However you probably find it in the same way as
you did 'nuke' portmapper.
As a suggestion install the 'debfoster' package, and run debfoster (when ever
you get bored as root) 'debfoster -n'. This will then list all the packages
installed on your machine and any dependencies that are linked to them, you
can then trim off the stuff you never needed...or forgot about that you
installed ages ago.
good luck
