RPC2 connection to testserver.coda.cs.cmu.edu:2432 failed with
RPC2_NOBINDING (F).

I needed to allow not just TCP connections to that box, now it shows:
# rpc2ping testserver.coda.cs.cmu.edu
RPC2 connection to testserver.coda.cs.cmu.edu:2432 successful.

however:
# cfs lv /coda/testserver.coda.cs.cmu.edu
/coda/testserver.coda.cs.cmu.edu: No such device or address

The firewall shows no dropped packages that's going to the testserver.

So I've found a misconfig in the firewall, but it's still not working
after fixing that. What should I check next?
