My mount attempts aren't working.

I turned on nfsd debugging and got...

Sep  3 17:34:00 rowlf rpc.mountd: authenticated mount request from gonzo.int.wil
.cx:787 for /pub (/pub)
Sep  3 17:34:00 rowlf kernel: found domain gonzo.int.wil.cx

Then I added full rpc debugging, and got this:

tcpdump confirms the same thing -- packets go in, but they don't come out.

victory, it is about death.  I've seen thousands and thousands of dead bodies.
Do you think I want to have an academic debate on this subject?" -- Robert Fisk
