(Old Sco Unix) How do I reset the root password if I forget it? (part 2)

(For Linux, see http://www.aplawrence.com/Linux/lostlinuxpassword.html)

This is another procedure involving manually editing files, and is specific to SCO Unix 3.2v4.0 through 3.2v4.2. The location of the encrypted passwords depends on the security settings. Look in /etc/passwd, /etc/shadow, and /tcb/files/auth/r/root; one or more of these will be used depending on how you have security configured. Follow the procedure in part 1 above; instead of editing /etc/passwd, edit the appropriate file(s) from the above list, and delete the encrypted password field. Note that formatting is critical; while you can delete the contents of the field, you must not remove separators, and making seemingly minor errors such as leaving blank lines can cause problems. Save, shut down, and reboot. C2 security will complain about what you've done; to make it happy, run /etc/fixmog. You may also want to run /tcb/bin/integrity and /etc/tcbck.

Is this 3.2v4.2?

Did you try /mnt/usr/bin/vi ?
