Hi I forgot the root password in solaris 2.6. Pls suggest me. Regards K.Karthick

First of all, you will need the Solaris Media (CD) and a CD-ROM drive attached to the machine. If you do not know what version of solaris you are running, login into the server as a normal user and type: uname -a which should return something like the following: SunOS yourmachinename 5.8 Generic_103640-08 sun4u sparc SUNW,Ultra-1 This means your server is running Solaris 8 (also call SunOS 5.8) Next we need to find out where the root partition is mounted, login into the server as a normal user and type: df -k / Filesystem kbytes used avail capacity Mounted on /dev/dsk/c0t0d0s0 241543 195738 21651 91% / In this case, the root partition is mounted on /dev/dsk/c0t0d0s0. Write this down somewhere. Insert the correct Solaris media in the CD-ROM drive To shutdown the server, type: Stop-A At the ok prompt, type: boot cdrom -s Wait for the system to finish rebooting. You will be brought to the root shell in single-user mode. From the command prompt, type the following to mount the root file system: mount [root-device] /mnt where the root-device is the device name you wrote down above, for example: mount /dev/dsk/c0t0d0s0 /mnt Edit the file /mnt/etc/shadow, when you open the file, the first line in the shadow file should look like this: root:0iIrCerpgZebQ:9783:::::: The second field (between the first and second colon) contains the encrypted root password. Remove it. In this case, the file should look like: root::9783:::::: After making your change, save the file Reboot the system sync;sync;sync;reboot You should now be able to login into the system without a password for root. The first thing you should do is set a new password for the root user and write it down.
