Solaris root password recovery


1. Put the installation CD into the CDROM drive and turn the machine on
2. while booting, press the Stop and A key simultaneously; the Stop key
is at the top left on Sun Keyboards, or Send a CTRL-BREAK (CTRL-C) to the system if connecting thru the console; serial port.
3. Either way, you should get {ok} prompt
4. type boot cdrom s and hit return without the quotes.
5. The machine will be booting in a single user mode off of the cdrom
6. When you get the hash prompt #, type cd /tmp and hit Enter
7. Issue the command mkdir /mnt without the quotes and hit Enter. If any
errors, use the p option; e.g., mkdir p /tmp/mnt.
8. Issue the command mount /dev/dsk/c0t0d0s0 /tmp/mnt and hit Enter. This will mount the old root / partition which is allows to modify the shadow file.
9. If any errors with mount, run the command fsck /dev/rdsk/c0t0d0s0 y
without the quotes which should fix the disk problems. Mount using step 8
10. Issue the command cd /tmp/mnt/etc and hit enter
11. Now you should be able to see the shadow file which you can edit or copy from the old version; you saved a copy right?
12. If you don t have the old password, just make the 2nd field blank
13. If you need to change the shell, edit password file.
14. Run fsck on other partitions as well such as /dev/rdsk/c0t0d0s7, etc.
15. halt and restart the machine, e.g., init 6, or shutdown g 0 y, or reboot, etc.
You should be able to login as before or just hit the enter for password.
