  not a stupid question at all.  as i'm still new to f11 alpha (as
we all are), perhaps there's some kind of firewalling beyond iptables
that i don't know about.  i've explicitiy turned off iptables as this
is on a local network.

  also, from my original post, i don't think it's any kind of
firewalling as "netstat" shows me that, even though mountd and nfsd is
running, there is *nothing* listening at port 2049.  i've never seen
that before.  i've always understood that an NFS server will be
listening at that port so it's puzzling.

  i checked on our regular RHEL4 server and, sure enough, netstat
shows lots of 2049 port listening.  as another test, i tried "telnet
localhost 2049" on the f11 alpha box.  nothing.  this is just weird.
what am i missing?
