nfs mount: Couldn't create default authentication handle
nfs mount: retrying: /itm
nfs mount: Couldn't create default authentication handle

Hi,

Could you give th release of ONCplus?
swlist |grep -i onc
Maybe you have to update it or another idea mount with nfs v4 .

Hi,
Thanks
# swlist |grep -i onc
ONCplus B.11.31 ONC+ 2.3

i have tried to mount as mentioned below also

# mount -o vers=4 192.168.1.234:/home/ITM_Installer /mnt
nfs mount: 192.168.1.234 NFS service not available RPC: Success
nfs mount: retrying: /mnt

Hi,
Did you have some errors on syslog when you do the mount?

Hi,
You could try to enable NFSv4 mounts.
An extract of the doc "the NFS configuration file, /etc/default/nfs, must be modified on the server. This file contains various configuration variables for NFS clients, NFS servers, and lock manager.
To enable clients to mount your NFSv4 file system, change the value of NFS_SERVER_VERSMAX to 4 in the /etc/default/nfs file as in Figure 11 by executing the setoncenv(1M) command.

Look at docs.hp.com/en/13578/nfsv4_whitepaper.pdf

Hi
nfs server is v2 and client is v3
there is no file names /etc/default/nfs on server
# uname -a
HP-UX HBPTCP3 B.11.23 U ia64 2700174893 unlimited-user license

hi,
please note that I can not mount only some machines.

[Sameer Kelkar]

r u able to get output from 192.168.1.234
#showmount -e

[yash123]

Hi Sameer,

Yes.
# showmount -e
export list for NFS12:
/home/ITM_Installer (everyone)
#

I can mount to some v3 and v3 machines.
But some machines can't.

Hi,
I suggest you to upgrade your ONClus look here
http://h20392.www2.hp.com/portal/swdepot/displayProductInfo.do?productNumber=ONCplus

http://www.docs.hp.com/en/5992-4685/ch01s06.html#VerONCplus

Maybe the workaround using nfs v4 is not a good idea if you have some box in v3.
If you could upgrade you ONCPlus and check if it resolve you case
