NFS client-side userid mapping
Folks,
I am trying to solve the following problem. I have a process on machine A running as root that needs to mount and access an NFS partition being exported from machine B.

However, I cannot have 'no_root_squash' option given on B, hence I see NFS requests from machine A end up as 'nobody' on machine B. What I'd like is that ALL NFS requests reach NFS server as a specific userid (other than root, ofcourse).

As far as I could read and find, there are mechanisms such as userid static mapping, but they exist on the NFS _server_ and not on the client.

Is there any flag, setting or way to get all NFS requests automatically map from root to a specified user-id on the NFS client?

Thank you much!

root on the client can become whatever userid you want... so the answer is to become the desired user when accessing the NFS area (from a script, you could use su or sudo or something like that).
