  • Recovering from lost root password in OpenBSD

    Want to recover a lost root password in OpenBSD, type boot -s at the boot prompt in OpenBSD hit enter when prompted for shell and enter vt220 as the TERM.

    boot> boot -s
Enter pathname of shell or RETURN for sh:
Enter Terminal: vt220

    Next run an fsck on the root filesystem and mount it read-write. If you have a seperate /usr filesystem then you should also mount it read-write. Finally run the passwd command to change the password.

    # fsck /
# mount -uw /
# passwd
