Hai friends, today we see about how to delete the forgotten password.
Step 1: For Redhat and Mandrake:-
Then boot from your first install CD and as the very first screen
comes up hit F2 and type:
rescue ( For RedHat "linux rescue" )
and the computer will boot in rescue mode.
It will show a few alternatives, select : ?mount the existing
partitions? and go to the shell/console prompt.
( Booting Mandrake in "failsafe" from the Lilo menu does the same )
Step 1: For SUSE:
Boot from your first install CD and press F1 at the first screen, then
choose "Rescue System" from the menu and at the prompt type "root" (
you do not need a password )
Step 1: For other distro's
Boot from the first install CD ( or any Live CD like Knoppix ) and at
the bootprompt type:
# cd /etc
We need to change two files; ?passwd? and ?shadow? in "/etc".
# vi passwd
( opens the file )
press 'i' ( puts vi in insertmode )
This is the first line:
root:x:0:0:root:/root:/bin/bash
Make it:
root::0:0:root:/root:/bin/bash
So just get writ of the ?x? do not touch the ?:? ( colons )
Save the file:
Esc
ZZ
Second file to be changed:
CODE
# vi shadow
( open the file )
< i > ( insert mode )
The first line is a long scrambled line of characters, just make it:
root:::: ( four colons ! )
Save the file
Esc
ZZ
Now you can reboot your computer. Log in as administrator , open a
console and type the following command.
$ passwd root
Set the new root password !
And the job is done !!
