WRT54G/Tomato 1.21++ Reconnect-Batchfile

UPDATE! I’ve updated the script to work for Tomato 1.25 (and hopefully upwards) – links below updated.

Some of you pirating people are downloading stuff from Rapidshare. Rapidshare, among other providers of free online storage and downloads, employ a policy that lets the user download a certain amount of data and then forces him to wait for a couple of hours before being able to again download something.

People (who are on dynamic ip connections) usually circumvent this by restarting (also ‘resetting’) their router. Some are clever enough to utilize tools for that task that log into your router and reset the connection.

People using Tomato however have been unable to use some of the Software written for that task, because as of Tomato 1.14 (changelog), in which the author fixed a cross site scripting vulnerability, just calling a URL on the Web-Interface won’t do it anymore.

I have written a php-script started by a batchfile that will let you reconnect your Tomato-running router with one click and no other tools than the ones provided.

The thing that Jon, the author of the Tomato and previously Tofu Firmware did was the following: He introduced a POST-variable into every form of the Web-Interface that would be transmitted upon clicking a button. As the content of this variable is created randomly after the first bootup of your router, a perpetrator using javascript to access your router’s WebIf would have no way of executing anything, as he doesn’t know that particular, 19 character long code.

You only do get to see this code when you log into your router’s WebIf – for which you need your router’s password – and view the source code. Since you probably want to save yourself the trouble of everytime hitting a shitload of buttons to reconnect your router, i wrote a script that retrieves that aforementioned POST-variable by logging into your router’s WebIf and afterwards submitting the commands for disconnection of the WAN-port and consecutive reconnection of the latter.

A short explanation on the files contained in the package:

• routerreconnect.php
  the script that i wrote and does all the work – edit this for your webif-password and router ip
• routerreconnect.bat
  the batch-file that calls the script
• exec – a folder containing files required for the script to work
  • php.exe, php.ini, php5ts.dll
    a very rudimentary distribution of php5(.2.6) – the ini file is the recommended version with curl-support edited into it – PHP License 3.0.1
  • php_curl.dll
    the curl php module required to send the commands to the router – PHP License 3.0.1
  • ssleay32.dll, libeay32.dll – Apache-style licence
    openssl files that are required for the curl extension to run (we’re not accessing ssl sites, but go on and try to disable that function in the module!)

I have tested this combination on computers that run neither php, nor openssl and it should work just fine on yours as well. This script has been tested with Tomato 1.19 and 1.21 (the latest one at the time of this posting) and worked well with both of them. As the WebIf doesn’t return any data after triggering its reconnection-function, it’s hard to debug if something goes wrong, hence i didn’t include any real status messages.

Anyway, here’s the download: router_reconnect_for_tomato_1.25.zip (2,92MiB from Rapidshare)
Mirrors: Megaupload

I’m not guaranteeing anything, but since the script shouldn’t break anything either, just try it, alright?
