Cannot login into AIX machine. Forgot Password!

Hi,

I cannot login to an AIX machine. The login mechanism was that we had disabled remote "root" logins.

We have only one user that can access over SSH and that is "userabc".

Probably have forgotten the password or it has expired. Is there a way to recover or login. I have the password for root but cant login through root. Please help :wall:

There is an AIX machine where we have implemented "Medium Level"security using AIXPERT utility provided within AIX.

root pw should not expire

if you just can't login remote, but you think you know the password, login with your user and try

su - root

if the user is not allowed to do this, you may login over hmc or serial

you could also boot your system with an aix cd or from the nim -> maintenance shell diagnostics and select mount filesystems

Insert base CD:

select SMS mode>Select Boot Options>Select Install or Boot Device>CD/DVD>Service Mode Boot>Start Maintenance Mode for System Recovery>Access a root Volume Group>rootvg>Access this Volume Group and start a shell.

passwd

Changing password for "root" ( this will be shown out" )
key in new password, afterthat,

sync;sync;sync;reboot

Rebooting...
Use the password that you had reset.
