Well, depends on what you plan to do...

I personally don't have anything running except smtp, and even that, I
run from daemon.  But your needs may be different.

Most probably, you don't need the first bunch.

Good Luck.

You can safely remove the portmapper and nfs. These are all only needed
for NFS (and rpc, which is used (omong other things) by nfs).

You can just add exit 0 to the beginning of the /etc/init.d/portmap
and nfs-* files to disable them. (Or remove relevant packages)

Also check your /etc/inetd.conf

Most services here can be turned off.

 I was reading a faq on  the net about securing a
 linux box and they recomend 
 to not have certain services enabled unless
 absolutly necessary. One of these 
 is portmap. I notice this is enabled by default (I
 think) on Woody. Can I 
 safely uninstall this service/program without

 All I'm using it for is surfing the net, reading
 email and other home type 
 things.

 Thanks for any advise.
 
 
Yes and yes. You might want to install the harden
meta-packages ( is that the correct terminology? ).

You've gotten the answers to your questions, already, but I'll point
you to 

www.debian.org/doc/manuals/securing-debian-howto/

for an okay primer to hardening your box, if you don't already know
about it.  I'm no security expert, but it seems to coincide with most
of the knowledge that I've seen on the net.

Good luck.

You probably don't need them, and to what I heard, they are quite
insecure.  I have them turned off, with no ill effects.  But I don't
run an internal network.

Actually, I don't even use inetd.  I have exim running as a daemon,
and the only thing I use the superserver for is leafnode, and I use
rlinetd for that.

Good Luck.
