Guys,

I have a problem with my RedHat 9 . When I tried to login as a user as well as root I got message as 'Authentication Failed'. How do I overcome this?.Do I need to reinstall the linux?. It doesn't go for password verfications. Please reply guys.

how exactly are you logging in, do you use ssh or telnet or are you actually using the window manager?

howzit

if for some reason u have forgotten your password then follow these steps:

reboot when reaching the grub press e to edit the bootup line and place a s or single at the end so that it will boot into single user mode. When system boots up chasnge password

cheers

Actually I am logging in using window manager. I found the reason , that's because my /etc/passswd has crashed
.How do I recover this ?. Or if you know the some other reasons give some ideas.

you should be able to view the /etc/passwd if it looks all mashed up then i cant help but you should have something like this

Code:

root:x:0:0:root:/root:/bin/bash

i have like 43 lines of text with pretty much all our users on plus some extras like webaliser and ftp.

you could try searching the etc folder as follows

Code:

ls -l "pass*"

and see if you get a passwd- or similar if you view it and it looks like the above root:x and so on then cp passwd- passwd reboot and try again

hope it helps
