5 Simple Linux user modification methods on linux with /etc/passwd file.

2. Now put the “*” in the second field in the “/etc/passwd”. i.e. change “x” with “*”.

[root@kalwa1 ~]# cat /etc/passwd|grep -i uxtechno
uxtechno:*:500:500::/home/uxtechno:/bin/bash
[root@kalwa1 ~]#

This change makes the user uxtechno unable to login with the system. System will simple say access denied.

login as: uxtechno
uxtechno@192.168.216.130's password:
Access denied
