chmod permission file /etc/passwd

[dangchung]

Hi all,
Pls help me. In SGSN E*******, I have a follow file /etc/passw:

-r--r--r-- 1 root sys 2165 Mar 1 09:45 passwd
when i chmod 777 passwd then file is
-rwxrwxrwx 1 root sys 2165 Mar 1 09:45 passwd
but a time later file auto rollback :

-r--r--r-- 1 root sys 2165 Mar 1 09:45 passwd

I don't know why. Have I kill process or call any process ?

Please help me.

Thank so much!

hi dangchung, first i think /etc/passw is a security sensitive file that you should never change it's permission to 777. second for your question, i think e******* have implemented some security infrastructure which prevents doing that either intentionally or unintentionally.
