The processing method of Linux and Unix root password forgetting

&http://www.aliyun.com/zixun/aggregation/37954.html ">NBSP; One: The solarisroot password forgets the processing method:

1, if you can log in with a regular user,%df/etc, determine the name of the device containing the ETC directory partition

%df/etc

//dev/ds
K/c0t0d0s0 ...

In this case, slice, if your root partition device is different, you can replace it.

2, insert the system disk into the CDROM

3, refresh the file system using the Sync command after the prompt appears

4, press Stop+a

5, "OK" state type boot Cdrom-s

6, type mkdir/temp at the # prompt, and then type mount/dev/dsk/c0t0d0s0/temp

If there is a situation where the hook is not on, then run fsck to Fsck/dev/rdsk/c0t0d0s0 and then mount

7,cd/temp/etc

8,CP Shadow Shadowbak

9,cat Shadow

Get the password string for root

root:djglcj0j:6453::: Where djglcj0j is the encrypted password string of root

10,sed s/djglcj0j//shadow>shadownew

11,cat Shadownew See if it has changed to

root::6453:::

12,CP Shadownew Shadow

13,CD/

Unmount/temp

Sync

Shutdown-i0-g0-y

14, after removing the CD, reboot the system, then root does not need the password!

That's OK!

OK Boot Cdrom-s

#TERM =sun

#export TERM

#mount/dev/dsk/c0t0d0s0/a

#vi/a/etc/shadow (Delete encrypted password for root)

#reboot
