find: cannot stat ......

[Sameer Mohbe]

Hi all,
Upon using "find" to get a list of core files, the system (10.20) returns the following error. The /sisko1 directory is remotely mounted over NFS. Some of the directories it is able to search recursively.

find: cannot stat /sisko1/ueein/stat/u323

Can any body tell me why this is happening?

Thanks in advance,

[Mark Mitchell]

How did you phrase the command?

[Sameer Mohbe]

I gave :
find / -name core -print -exec ls -ls {} \;

probably some directories you don't have permission on, I guess.

NFS is not like other filesystems, especially because it is shared across the network. By default, root on the client machine has no special rights to read or write files on an NFS server. Indeed, root is nobody. Check the passwd file and you'll see the special user ID given to NFS users (user and group ID is -2).

The message: Cannot stat is a shorthand way of saying that permission to read information about a file or directory is denied. With root deprecated to nobody, there may be several directories and files that cannot be seen.

You can edit the server's exports file to give away permissions, but be careful. Read the details in the man page for exports.
