Using OpenVMS as a PC-NFS server


Using OpenVMS as a PC-NFS server

I am trying to set up my OpenVMS system with TCPIP service v5.3 with PC-NFS to assign the UID/GID pairs to my PC clients.

According to the documentation this is the sequence of events :-

1) The PC client sends a request for its UID/GID pair. This request includes the PC's host name with an encoded representation of the username and password.

2) PC-NFS responds by searching the proxy database and SYSUAF for a matching entry and by checking the password.

3) If a matching entry is located, PC-NFS returns the UID/GID pair to the PC client. The PC stores the UID/GID pair for later NFS requests.

4) If PC-NFS does not find an entry for the PC client in the proxy database, it maps the PC client to the default user TCPIP$NOBODY
account. In this case, restricted access is granted based on privileges established for the default user account.

Trouble is the PC-NFS never seems to find a match, and I always end up with the default user.

Is there anyway to see what the PC-NFS server is receiving and that is needs to match to interms of user name, host name etc. ? And is there a way to turn on logging to see what requests are received and what the status is ?

Any input appreciated.

Thanks Andrew

Re: Using OpenVMS as a PC-NFS server

from a privileged account could you do

$set proc/priv=all

this will echo all the messages to screen

then try and do a client PC-NFC connect you should see more information on the connection attempt.

relay the info here, perhaps this will enable someone to find the solution to your problem

You should be able to get info re nfs connections from the logfiles in sys$sysdevice:[tcpip$nfs]and from operator.log.

By the way have you set up a vms username for each nfs client?

$ mc authorize sho/br nfs0049
Owner Username UIC Account Privs Pri Directory

NFS0049 [4000,61] Normal 4 DISK:[USER]

TCPIP> sho proxy nfs0049

VMS User_name Type User_ID Group_ID Host_name

NFS0049 OND 61 4000 *
