Subject: Trouble with krb5 mounts with multiple hostnames/networks
Date: Fri, 6 May 2011 21:08:09 +0000 (UTC)	[thread overview]
Message-ID: <loom.20110506T230745-58@post.gmane.org> (raw)

We have a setup where some machines have two network connections, one of which
is dedicated for nfs traffic.  The nfs network interface will have a hostname
with a "g" suffix.  e.g. saga's interface on the nfs network is called "sagag".

This has worked fine for years with nfs3, and am now testing out nfs4/krb5.  I
can connect fine with the normal hostname, but trying with the nfs network name
fails:

# mount -t nfs4 -o sec=krb5  alexandriag:/cora2 /mnt
mount.nfs4: Permission denied

I've added krb5 nfs principals for both hostnames in each machine's
/etc/krb5.keytab.

I'm running centos 5.6 with nfs-utils-1.0.9-50.el5.

Is there any hope of this working with nfs4/krb5?  Or is this just not going to
fly because of hostname authentication issues?
