Debian, that triggers the first question, do you run the same kernel as the
headerfiler are in /usr/include/linux/*. Just have to ask, been bitten by
if too many times.

If the cell has the same name as the REALM, that should be not be needed.

Since it will talk to the afs-servers to fetch the rootvolume.

Did you build with pthread support or with lwp ? (--with-pthreads ?)

NAT will work somewhat depending on our NAT. NAT is evil, but in this case
I think the fault is arla's.

It wont work until the communicaition stuff is cleared out and working good.

That's really weird. You have a modern tcpdump (www.tcpdump.org) (like 3.5)
that will unpack your afs-packets and print them in a readable form ? That
might help you a bit.
