o If you still remember the root password and IP address of the
machine and it is configured to allow root login from non-system
consoles.
1. Apply power to the system.
2. In order to get the system to boot, use the power switch on
the rear of the machine to start the automatic boot process.
3. Once the system has had a few minutes to boot to UNIX, telnet
or rlogin to the system as the root user from another machine
on the network.
4. Once logged in, edit the /platform/sun4u/kernel/drv/lom.conf
file and modify the line that reads 'serial_security=1' to
read 'serial_security=0'. Write the modified file and then
reboot the machine - issue an 'init 6' or 'reboot' command.
5. As the system boots it will examine this file as part of the
boot process and will disbale the security passwords setup in
the LOM processor, allowing access to the LOM without
passwords.
6. On the LOM/Console port, issue the '#.' escape sequence to
access the LOM, and use the 'usershow' command to list the
users that have been configured.
7. Use the 'userdel' command to delete the users and their
passwords.
8. The system is now configured without serial security, to
issue the 'console' command to get back to the system
console.
9. Edit the /platform/sun4u/kernel/drv/lom.conf file and modify
the line that reads 'serial_security=0' to read
'serial_security=1' to re-enable the security checks
following the next system reboot.
o If you cannot remember the system root password, or the system is
not configured to allow root logons from non-system consoles, or
you do not know the IP address of the machine, you must use
another machine to overcome the problem. Locate another X1 that
does not have the security problem above, you will need to make
some modifications to this machines setup and then remove the boot
drive from this machine and temporarily place it in the problem
machine.
1. Having located another X1, make sure that the following
configurations are correct :
+ The root password is known.
+ The machine is configured to allow root login from
non-system consoles. Edit the /etc/default/login file on
the machine and insert a '#' at the start of the line
that reads 'CONSOLE=/dev/console'.
+ Edit the /platform/sun4u/kernel/drv/lom.conf file and
modify the line that reads 'serial_security=1' to read
'serial_security=0'.
2. Power down this machine using 'init 5'.
3. Remove the top cover of the machine and remove the Boot disk
drive.
4. Remove the boot disk drive from the problem machine.
5. Replace it with the boot disk you prepared in the other
machine.
6. Boot the machine and follow the process above from step 6.
7. Once the LOM passwds have been removed at the beginning you may
shut the system down and replace the original disk drive.
