NFS user ID problem

vielmaj · 08-08-2011, 08:36 PM

Hello,

I upgraded from Debian Squeeze to Ubuntu 11.04. I did a fresh install and transferred the user information from the old system to the new system (/etc/passwd, /etc/shadow).

If I ssh into the server and run ls -l I get the following.

total 19512
drwxr-xr-x 8 vielmaj users 928 2011-07-31 16:55 BaTiO3
drwxr-xr-x 3 vielmaj users 120 2011-06-22 17:36 BiFeO3
drwxr-xr-x 2 vielmaj users 568 2011-07-28 08:36 bin
drwxr-xr-x 9 vielmaj users 312 2011-06-22 17:38 BTO
drwxr-xr-x 6 vielmaj users 160 2011-04-01 14:24 BTOFit

If I ssh into a client and run ls -l I get this

total 19512
drwxr-xr-x 8 4294967294 4294967294 928 2011-07-31 16:55 BaTiO3
drwxr-xr-x 3 4294967294 4294967294 120 2011-06-22 17:36 BiFeO3
drwxr-xr-x 2 4294967294 4294967294 568 2011-07-28 08:36 bin
drwxr-xr-x 9 4294967294 4294967294 312 2011-06-22 17:38 BTO
drwxr-xr-x 6 4294967294 4294967294 160 2011-04-01 14:24 BTOFit

I am not sure where to begin.

Thanks,

Jason

Probably the first thing to try is changing the owner of files like this:

Code:

(as root):
chown -R vielmaj:users /whatever_directory/

where -R means recursive (it will change all files and directories under the parent).

But since the groups are showing up 2^32-2 makes me think that the chown may not work. Try it out and post what happens.

I have tried that on the client machine. I get the following for all the files.

chown: changing ownership of `BTO/GGA_Database/RhomDisp/Fit198': Invalid argument

Did you upgrade the client or the server?

What kind of authentication are you using to map the UIDs and GIDs - NIS/LDAP/Kerberos ?

Did you switch from debian to ubunto on the server or on the client?!

Looks like the client uids/gids are different than on the server.

I upgraded both the client and the server. I am using NIS.
