mount nfs problem

Post by Jakub Buzo » Wed, 02 Jun 1999 04:00:00



Hello,

I try to mount on my AIX 4.3.2.0 directory exported on UW 2.1.3
(NFS version 2). :

$ />mount -o rw -v nfs unixware:/home1/help /home1/help
mount: giving up on:
unixware:/home1/help
vmount: I/O error
NFS getattr failed for server unixware: error 7 (RPC: Authentication error)

Other systems work fine. Any suggestions?

1. mounting nfs problem

I would usually try to state the problem first, but without the
background info, even I get confused.

Name     IP        Machine       Comments
hs       .1        aix 3.2.5     dns server
walter   .2        Linux 1.3.85  Pentium 100,pci,32M,eth0 is 3c503/16
         .33                                    eth1 is 3c595 in 10bt  
ns       .43       Linux 1.3.85  386/25,4M,eth0 is ne2000 clone

walter serves as a router between the 10b2 subnet(1) and the 10bt subnet(2).
The subnet mask is 255.255.255.224

From ns, if I try "mount -t nfs walter:/cdrom /cdrom" I get NFS server
not responding, still trying
         if I try "mount -t nfs 199.233.164.33:/cdrom /cdrom", it works.

From hs, mounts to either ip(.2 or .33) succeed.

I thought it was a routing problem, but everyone is pingable from
everyone else.

The routing table on walter is
Destination     Gateway         Genmask         Flags MSS    Window Use Iface
207.86.80.1     *               255.255.255.255 UH    512    0        2 ppp0
199.233.164.0   *               255.255.255.224 U     1500   0       13 eth0
199.233.164.32  *               255.255.255.224 U     1500   0      101 eth1
127.0.0.0       *               255.0.0.0       U     3584   0        2 lo
default         207.86.80.1     *               UG    512    0        9 ppp0

The routing table on ns is
Destination     Gateway         Genmask         Flags MSS    Window Use Iface
199.233.164.32  *               255.255.255.224 U     1500   0        2 eth0
loopback        *               255.0.0.0       U     3584   0        1 lo
default         199.233.164.33  *               UG    1500   0        1 eth0

I could really use some suggestions, as I dont want to have to specify
the secondary interface address when mounting cdroms by nfs.

Thanks,
