These are rather odd.  Never seen them around, not open on this machine (big
hulking fileserver, if you're wondering).

What gives you the idea it's related to NFS?

What's got them open?  lsof is your friend (lsof -i tcp:748 and lsof -i
tcp:779) and you can shut them down.  If it's inetd that's got them,
inetd.conf will fix it.  Otherwise, kill the programs and hunt down the
binaries and either delete them or fix them somehow to stop them from
running when you don't want them to.
