Greetings,
A quick question, if you please. I am trying to tighten up security on
a
box that may be exposed to some security risk. In doing so, I have been
trying to get rid of anything that might prove detrimental to security
(ftpd, telnetd, and other things). I have been running nmap

But what about 111? Something in my gut says that
remote procedure call can't be all that good.
NIS and NFS need sunrpc (aka portmapper) running on the server, but you
should be able to shut it off if you're not using either

Now, I know that 9 will just throw away anything it
Port 111 is the portmap daemon, used by NFS and NIS (anything else?).
It doesn't look like you're using NFS or NIS (if so you'd have other
ports open) so you can probably shut it off. If you do want to keep it
on, it might be worth it to use something like ipchains or iptables to
filter
I am not using NFS or NIS, and I have started to hunt down
how/where to turn
off portmap.
Hmmm...
I check out things in /etc/init.d. Ahh... mountnfs.sh!
But wait! I read through the script It shouldn't be on! There's
nothing to turn it on.
You know, I should really look at the
