1. NFS mount from AIX 4.2 to SunOS 5.1 fails after upgrade
Greetings,
One of my customers just upgraded an RS/6000 43P from
AIX 4.1 to 4.2.1. Before the upgrade he was able to NFS mount
a filesystem on a Sparc 1+ (yeah, an oldy) running SunOS 5.1. As
near has he can tell (he did a preservation upgrade on the AIX)
he has not changed any TCP/IP configuration on either side.
Here is what he receives on the AIX side:
mount: 1831-008 giving up on:
mrd2100-gw:/soma
vmount: There is an input or output error.
NFS getattr failed for server mrd2100-gw: error 7 (RPC: Authentication
error)
While on the Sun side he receives on the console:
NFS request from unprivileged port.
nfs_server: weak authentication
The /etc/filesystems entry on the AIX side is:
/mrd2100-gw/soma:
dev = "/soma"
vfs = nfs
nodename = mrd2100-gw
mount = false
options = fg,hard,intr
account = false
while on the Sun side it's filesystem is being shared with a
/etc/dfs/dfstab entry of:
share -F nfs -orw=omronaix,root=omronaix /soma
He has tried changing parameters like hard/soft, intr/nointr, secure
vers=, proto=, but none of these has changed the symptom.
I went looking through IBMLink but didn't find any PTF about this
specifically. We are going to pull down U450645 and see if that
helps, because it is pointed to by about a dozen APARs, but that is
just a blind guess. We also found out that bos.net.tcp.client is
at 4.2.1.2, but bos.net.nfs.client is at 4.2.1.1, and it probably
should be at 4.2.1.2 also.
I also am going to try Sun patch 100884-27, the SunOS 5.1 NFS jumbo
patch, although I am not sure this will really help. It hasn't been
updated since 1994.
Do any of you have any suggestions?
Thanks in advance,
John Schneider
