Do you have any firewall rules enabled? I'd start by disabling iptables
(or at least setting everything to ACCEPT) and as someone else suggested
setting selinux to permissive/disabled.
Why are your nodes and client using different versions of Gluster? Why
not just use the 3.2.6 version for everything? Also, I'm not sure where
port 6996 comes from - Gluster uses 24007 for it's core communications
and ports above that for individual bricks.

Hi, All:
I've built a Gluster-based storage cluster on a pair of CentOS 5.7
(i386) VM's. The nodes are using Gluster 3.2.6 (from source) and the
host is using Gluster 3.0.0 (from the Mageia package repositories):
|[eric@node1 ~]$ sudo /usr/local/sbin/gluster --version
glusterfs 3.2.6 built on May 3 2012 15:53:02
||[eric@localhost ~]$ rpm -qa | grep glusterfs|
|glusterfs-common-3.0.0-2.mga1|
|glusterfs-client-3.0.0-2.mga1|
|glusterfs-server-3.0.0-2.mga1|
|libglusterfs0-3.0.0-2.mga1|
None of the systems (i.e., neither the two storage nodes nor the
client) can connect to Port 6996 of the cluster (node1.example.com &
node2.example.com) but the two storage nodes can mount the shared
volume using the Gluster helper and/or NFS:
|[eric@node1 ~]$ sudo /sbin/lsmod | grep fuse
[eric@node1 ~]$ sudo /sbin/modprobe fuse
[eric@node1 ~]$ sudo /sbin/lsmod | grep fuse
fuse 49237 0
[eric@node1 ~]$ sudo mount -t glusterfs node1:/mirror-1 /mnt
[eric@node1 ~]$ sudo grep gluster /etc/mtab
glusterfs#node1:/mirror-1 /mnt fuse
rw,allow_other,default_permissions,max_read=131072 0 0|
...but the host system is only able to connect using NFS:
|[eric@localhost ~]$ sudo glusterfs --debug -f /tmp/glusterfs.vol /mnt

I've read through the Troubleshooting section of the Gluster
Administration Guide
<http://download.gluster.com/pub/gluster/glusterfs/3.2/Documentation/AG/html/chap-Administration_Guide-Troubleshooting.html>
and the Gluster User Guide
<http://www.gluster.org/community/documentation/index.php/User_Guide#Troubleshooting>but
can't seem to resolve the problem. (See my post on the Mageia Forum

all the troubleshooting details:

What might be causing this?
