Hi,

I don't know how the owner & group of a login file in redhat linux 7.2 changed to bache like,
-rwxr-xr-x 1 bache bache 17740 Jun 20 02:05 login

I am trying to change the owner and group to root by using
#chown root login
#chgrp root login
But i am getting the error
chown: changing ownership of 'login': Operation not permitted

Pl can i know the reason and solution for the same.
I am waiting for your valuable response.

Thanks,
Bache

try doing in in single user mode.
#init S

I tried in single user mode also, here also same error.
If i copy login file from some other linux m/c whether it will works or not or how to reinstall login package.

Thanks,
bache

chown root:root login

have you tried this one?

root@thambura bin]# chown root:root login
chown: changing ownership of `login': Operation not permitted

[root@thambura bin]# ls -lt login
-rwxr-xr-x 1 bache bache 17740 Jun 20 02:05 login

Same error, Any other method to change

Try the following:

# su - bache
$ cd /bin
$ ls -lt login
-rwxr-xr-x 1 bache bache 17740 Jun 20 02:05 login
$ chown root:root login
$

Again same error has above
