Description Ed Marshall 2006-10-31 18:11:28 EST
Description of problem:
After upgrading my NFS (v4) server from FC5 to FC6, I need to open up my
iptables firewall for ports other than 2049.

Version-Release number of selected component (if applicable):

How reproducible:
Every time.

Steps to Reproduce:
1. On the nfs server, install FC5 with SELinux (targeted policy) and iptables
enabled. Permit TCP traffic to arrive via port 2049:

-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 2049 -j ACCEPT

Configure NFS to export a shared home directory space. /etc/exports:


(plus a bind mount in /etc/fstab for the /home -> /srv/nfs/home translation)

On the client (previously FC5, now FC6, same configuration both ways),

* -fstype=nfs4,rw,proto=tcp,port=2049 nfsserver:/home/&

And /etc/auto.master:

/home /etc/auto.home --timeout=90

On both client and server, set up /etc/idmapd.conf to specify nfsnobody as the
user and group, and a common domain.

2. Watch as /home automounts wondefully on the client.
3. Upgrade server to FC6, watch as client can no longer automount directories in

Additional info:
Completely disabling the iptables firewall on the NFS server has corrected the
problem as a stop-gap measure. I haven't had a chance to spend much time
debugging this yet, as we just needed the machine back up and running; I'll try
to spend a bit of time with ethereal over the next few days seeing what
specifically isn't working.

I'm basing this approach on the documentation found here:

Would it be possible to post a bzip2 binary tethereal network trace
of the mount? Something similar to 

tethereal -w /tmp/data.pcap host <server> ; bzip2 /tmp/data.pcap
