NFS ownership changed.

[Rajeev Tyagi]

Experts,

In our environment we are using NIS for user authentication and NFS mounted home directories. There were couple of cases in past one month when users home directory ownership was changed to uid 120657. Any help in this regard will be appreciated.

Who is the user with the uid of 120657?

What was the uid of the owner of the /home directory?

do they have similar user names?

Do you have only one NIS master in your network?

Were any other directory and/or file ownership's changed?

Are there local users on the machines with uid = 120657 or equal to the original owner?

Sounds like an NIS slave isn't getting updated.

The user id probably exists on multiple machines and the numeric id is not the same on all machines in /etc/passwd or the NIS database.

That user is changing the ownership.

I'd check communications and perhaps run yppush (I think) from the Master and check for error codes.

Harry/Steven thanks for your reply.

Harry,

User ID 120657 is not assigned to anyone. And UserID of owner home dir was 10180. This user is assigned only one uid. There is only one NIS master on this network. And ownership was changed only for this users home directory.

Steven,

On couple of systems this userid was defined locally but with same uid 10180. Also yppush worked successfully.

Also before this issue another users home directory ownership was changed to uid 120669 and his actual uid was 10304.
