Re: unix root password
Reboot your machine in single mode. Afterwards for instance in Solaris you have to change your root passwd.
mount your disk involving your /etc directory.
Go into /etc and edit the shadow file with vi.
the 1st line usually looks like this:
root:sdo3md3:1245:::::
The second entry (here sdo...) has to been deleted in such a way that the first line look like this:
root::1245:::::
Reboot your machine in normal mode (no rootpasswd is needed to login!)and change your rootpasswd using passwd.
