netstat -> Needed services? [solved]

When I issue "netstat -atu", I get two "listeners" that I doubt are needed.
They are:

Proto Recv-Q Send-Q Local Address Foreign Address State
tcp 0 0 *:sunrpc *:* LISTEN
tcp 0 0 *:951 *:* LISTEN
udp 0 0 *:sunrpc *:*

Neither give a PID/program name when I use -p as extra parameter.
Are these a security risk?

"locate sunrpc" refers to /usr/lib/perl5/5.8.4/i686-linux/sunrpc , but I don't really know if it is necessary to have running.
The 951 listener I cannot find somehow.

Can anyone tell me how I can find these processes and how to remove them (if recommended).

I'm running the vanilla 2.6.7 kernel.

Thanks

EDIT: it was portmap and famd. Supposedly needed for Nautilus (see setting up Gnome desktop)

sunrcp is portmap (/etc/init.d/portmap for your convenience : ), which is needed for nfs.

951 is probably BIND named (/etc/init.d/named), the dns server.

You probably want to use iptables to close those ports to external access, if you're worried about them. Keep them open for access over loopback, though.
