I am developing a system in PHP wherein I can change the IP Address and Subnet in web form.

I need assistance here becoz I cannot solve this problem.

Here's a code:

Code:

<?php

echo "Old IP: ".$old_ip;
echo "New IP: ".$stat_ip;

system("sed -i 's|".$old_ip."|".$stat_ip."|g' /etc/.../.../ifcfg-eth0");

?>

the error is "unterminated 's' command"... what is the right syntax for here?

thanks~

For a start do away with all those double quotes you're using. Check out the link in my signature about quotes to see how to tidy that up.

You're using pipes instead of a forwardslash:

Code:

system('sed -i \'s/' . $old_ip . '/' . $stat_ip . '/g\' /etc/ifcfg-eth0'); // sed expects: sed -i 's/oldText/newText/g' /path/to/file 

I hope you are taking precautions to prevent people from being able to execute this remotely. It wouldn't be very difficult to render your box inaccessible remotely or worse.

thanks for the reply...i'll check on these..

My linux is rusty at best, but I thought the pattern re-placer would allow pipebars as delimiters?
The error itself is definitely not a PHP error though, so its the usage of SED that's causing that. I'll move this to the computer programming forum instead.
