DECSystem 5100 running ultrix password recovery

Udgivet den oktober 24, 2003 af mike

i mounted /usr and got access to ‘vi’ and also ‘passwd’ changed the root pass and logged in. Here is a short guide on how to do when or if the problem arises for somebody else:

How to recover root password on Utrix 4.4 or DECsystem 5100, proberly works on other systems as well.

Boot the system, when the fsck begins (harddisk checking) press ctrl+c (might be names ‘code’ instead of ‘ctrl’ if your on a vt420 terminal)

You will now be granted with a root promt in singelmode, now type ‘mount /usr’ and then ‘passwd’ you will now be asked for the password you want to set to be roots, type it in, afterwards it will ask you to repeat, do that to.

Now type reboot and log in with your new password.
