Re: 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 .

Re: nfs mount: Couldn't create default authentication handle

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

Re: nfs mount: Couldn't create default authentication handle

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

Re: nfs mount: Couldn't create default authentication handle

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.

Re: nfs mount: Couldn't create default authentication handle

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

Re: nfs mount: Couldn't create default authentication handle

NFS v4 is not available on 11i v2. You will not be able to do an NFS v4 mount between 11i v2 and 11i v3 systems.

Does mounting filesystems with NFS v3 work?
