hi friend,
i cann't login as root or user in red hat linux8. if i go to single user mod and change the password for root , the below error comes
" changing password for user root
segmentation fault". so i cann't login?

1. i don't move /etc/passwd
2. i don't move /etc/shadow
3. not change login shell (/bin/bash)

what would be the problem . help me to login?

THANKS

Segmentation faults are usually caused by 1 of a few things:

Buggy code (unlikely in passwd)
Bad memory (unlikely if reproducable)
Bad compilation (possible, unless installed from rpm)
Bad version of libc
Hacked system (good passwd replaced with a bad and buggy one)

Any of those sound likely on your system?

thanks for Ur response

1. no way to hack my linux PC because it has intranet.
2. i did not install any packages

but i have just view some configuration files.
due to this , some files may be changed.(without my knowledge)

Highly unlikely. How can you be so certain that your system has not been cracked?
