NFS VMS to Linux Permission denied
We have VMS-directories exported via NFS from all our VMS-systems to a Linux-server.
OpenVMS 8.3, Tcp/IP 5.6 ECO3, RedHat 5.5.
As this server is very critical, we have cloned it, to have a spare hot standby system.
This is in VMware, so it really is a cloned system.
Problem is that I can't mount the exported dirs in the clone. I get permission denied.
The /var/log/messages has this:
server HUVTS1.HUV.DAGAB.SE requires stronger authentication.
To avoid any potential conflicts I set up an export from my Alphastation.
That one works on both Linux systems.
None of the other exports work on the clone.
Therefore I made a new export on one of our VMS-systems.
This one has the same problem as the others.
It only works on the original Linux server.
The involved systems is added to the local host databases in both VMS and Linux.
Hosts.allow and deny is empty.
Telnet in both directions works fine.
I've been banging my head to the wall for some time now and really don't know how to troubleshoot this further.

Re: NFS VMS to Linux Permission denied
the cloned VMS sees node 194.132.89.68 instead of the DNS name.
Are there TCPIP (OND) proxies for this node ?

Re: NFS VMS to Linux Permission denied
Accept and close connection shows ip-address i both cases.
The real difference is that the cloned system makes two connections.

Re: NFS VMS to Linux Permission denied
I also tried to nfsmount to the IP-address with the same result.
As I mentioned before, I tried Telnet and ssh in both directions using both names and adresses without problem.

Re: NFS VMS to Linux Permission denied
Were you ever able to solve this problem? I have the same problem (See post made by mjkushner this morning December 1, 2011).
Thanks,
Mark Kushner

Re: NFS VMS to Linux Permission denied
Actually, I was wondering about the same thing. I've been running into the same problems with NFS server under OpenVMS, whilst trying to mount a share under a UNIX operating system.
