change root password in NIS sever

[j773303]

Does anyone has the experience how to change the NIS server root passwd. I got the below err msg. Thanks.

#yppasswd root
Invalid login name.

Hi,

Normaly the root user does not have a nis entry. Login in on the NIS server and change the root password with the passwd command.

Hi,
I agree wit Robert-Jan.

Usually root is local, otherwise you could not be ablo to login when booting without network :)

So you have to change the password locally on each server.

Why it got the below message ? Is passwd can change root password ? Thanks.

#passwd root
Supported configurations for passwd management are as follows:
passwd: files
passwd: files ldap
passwd: files nis
passwd: files nisplus
passwd: compat
passwd: compat AND
passwd_compat: nisplus

Hi,

I think you set-up a wrong /etc/nsswitch.conf file. Check the examples like /etc/nsswitch.nis.

I assume you should use: passwd files nis

Ans indead like others mentioned root should be in the local passwd file.

Think Peter is right,

Check this doc from the ITRC database or post your /etc/nsswitch.conf
