Changing ip address of apache server using php
Question by apurv nerlekar
I am trying to create a settings page(for the clients) where in they can view the current up address,change the ip address etc. I have a php file to view the ip address
<?php
$res=shell_exec("ifconfig");
echo $res;
?>
This code works just fine and displays the expected result.
However the code to change the ip address of the server is not working properly.
<?php
shell_exec("ifconfig eth0 192.168.163.136");
?>
After running this code when i check the ipaddress on the terminal using ipaddr i don’t see any change in the ipaddress.
Pls point out where i am going wrong. I think its a problem of apache not being a super/root user. If that is the case i don’t know how to make apache run as a root user.

IP address are configured in Network Layer of an Network Protocol, not in application layer where PHP runs. Simply, PHP does not have access to it and cannot changed them.
Just imagine the vulnerabilities it could create if this was possible.
