chown: Not owner

panchpan — Wed, 31 Oct 2007 03:01:43 GMT

Hello.

I have two user IDs. user csms and user ftpcsms. csms is normal user ID and ftpcsms is ftponly and belongs to group ftponly. csms also is a part of group ftpcsms. But csms is not able to modify the ownership of a file created by him to ftpcsms.

-r-xr-xr-x 1 bin bin 24576 Nov 14 2000 /usr/bin/chown

All looks good with chown. The error just says 'not owner' ... Any fix of it?

thank you!

You should post the owner of the file trying to change the owner.

If the file is uploaded, maybe an "auto change owner" is enabled, and the file is not owned by the csms.

A non-root user cannot change the owner of a file. From the chown man page:

Only a user with superuser authority can use the chown command.

I do admit that the error message is somewhat obscure :)

Please take a look at what you posted.
By looking at the file I can see there is no w writable permissions on the file.
However if both users are in the group, the owner of the file can change the permissions and give it writable options to group as in
Root Group World.
r-x r-x r-x

That should let you write to the file and any other one in the group.

fwiw, the same question was posted in the hpux forum two minutes later. Subsequent replies indicated the systm was hpux.
