Buenas buenas, estuve buscando por Internet y en los foros mismos de JDownloader y no encontré un script para reiniciar la conexión de un router ejecutando el firmware Gargoyle (el cual es una interfaz del firmware OpenWRT) por lo que decidí realizar uno.

Lo hice "a las apuradas" (quick & dirty) y solamente lo probé con mi router TP-LINK TL-WR1043ND.

El código del script es el siguiente:

[[[HSRC]]]
    [[[STEP]]]
        [[[REQUEST]]]
            POST /utility/get_password_cookie.sh HTTP/1.1
            Connection: keep-alive
            Content-type: application/x-www-form-urlencoded
            Accept: */*
            Accept-Charset: UTF-8
            Host: %%%routerip%%%
            password=%%%pass%%%
        [[[/REQUEST]]]
 
        [[[RESPONSE keys="hash"]]]
           hash=(.*?);
        [[[/RESPONSE]]]
        [[[RESPONSE keys="exp"]]]
           exp=(.*?);
        [[[/RESPONSE]]]
        [[[RESPONSE keys="browser_time"]]]
           browser_time=(.*?);
        [[[/RESPONSE]]]
    [[[/STEP]]]
 
    [[[STEP]]]
        [[[REQUEST]]]
            GET /login.sh HTTP/1.1
            Cookie: hash=%%%hash%%%; exp=%%%exp%%%; browser_time=%%%browser_time%%%;
            Connection: keep-alive
            Content-type: application/x-www-form-urlencoded
            Accept: */*
            Accept-Charset: UTF-8
            Host: %%%routerip%%%
        [[[/REQUEST]]]
    [[[/STEP]]]
 
    [[[STEP]]]
        [[[REQUEST]]]
            GET /overview.sh HTTP/1.1
            Cookie: hash=%%%hash%%%; exp=%%%exp%%%; browser_time=%%%browser_time%%%;
            Connection: keep-alive
            Content-type: application/x-www-form-urlencoded
            Accept: */*
            Accept-Charset: UTF-8
            Host: %%%routerip%%%
        [[[/REQUEST]]]
    [[[/STEP]]]
 
    [[[STEP]]]
        [[[REQUEST]]]
            GET /basic.sh HTTP/1.1
            Cookie: hash=%%%hash%%%; exp=%%%exp%%%; browser_time=%%%browser_time%%%;
            Connection: keep-alive
            Content-type: application/x-www-form-urlencoded
            Accept: */*
            Accept-Charset: UTF-8
            Host: %%%routerip%%%
        [[[/REQUEST]]]
    [[[/STEP]]]
 
    [[[STEP]]]
        [[[REQUEST]]]
            POST /utility/run_commands.sh HTTP/1.1
            Connection: keep-alive
            Content-type: application/x-www-form-urlencoded
            Accept: */*
            Accept-Charset: UTF-8
            Host: %%%routerip%%%
            commands=ifup wan&hash=%%%hash%%%
        [[[/REQUEST]]]
    [[[/STEP]]]
[[[/HSRC]]]

Debería funcionar en cualquier dispositivo que se encuentre corriendo Gargoyle.

Sería bueno que los desarrolladores lo incluyeran en futuras revisiones de JDownloader.

Aparentemente la versión anterior del script fallaba a veces en renovar la conexión.
La cuestión principal está en el manejo de las cookies debido a que Gargoyle utiliza un hash al momento de enviar comandos a ejecutar con el fin de prevenir Replay Attacks (seguiré investigando ésto).

Mi "laboratorio" de pruebas consta de:

• Router TP-LINK TL-WR1043ND v1.8 (Firmware: Gargoyle 1.5.9)
• Sistema Operativo: Windows 7 Professional x32
• JDownloader 0.9.581
• Wireshark 1.8.4
