Re: enable root login

Hi,

Is it trusted or non-trusted?

root account get locked only in trusted system due to improper config. You should not set system security policies for root account.

Follow these steps.

1. Boot the system in to single user mode.

2. Mount /usr file systems.
# mount /usr

3. Use the following command to reactivate the 'root' account:
# /usr/lbin/modprpw -k root

4. Use the 'modprpw' command to null the password, so that the passwd command does not prompt for the old password.

# /usr/sam/lbin/usermod.sam -F -p "" root

5. Change the root account password.
# passwd root

6. Boot the system in to multi user mode.
Best wishes,

Ganesh.

Re: enable root login

HI Ganesan,

Its not trusted system.

actually what happened is ,i disabled ssh root login my adding "permitrootlogin no" in sshd_config file.After that i was not able to login using root.
Then i logged in to the console and rolled back what i have done in sshd_config.

Now i can login as root.

But i dont understand,why i was not able to login as root.

How were you trying to login as root? Were you doing a telnet, ssh, what?

Hi,

Answer is there in your post itself.

"permitrootlogin no"

This will disallow the ssh root logins.
