I got this app yesterday on Cydia - BigBoss repository - called 'mptcp'. So follow this steps: * Look for 'Mptcp' on Cydia (BigBoss respository - The BigBoss repository is default on the Cydia installer, so look for Mptcp directally on Search Option in Cydia). * Install Mptcp and open the terminal console on iPhone (or use ssh mode to connect it). The app Mptcp is a console mode only !! * Run 'mptcp' on the terminal. *** PS: The app have many options, so look for -r option (range ip-ip). * Make sure there is a wireless connection up, ie, connect naturally to wireless network that you want take down. * On iPhone go to Settings app >> Wi-Fi >> and note yourself IP address. * Now, you know your IP address and know the information about this network (know about range IP address) * Run mptcp -r ip-ip, ie: mptcp -r 10.1.1.4-10.1.1.254 * So all connections on the range 10.1.1.4 and 10.1.1.254 will be take down. PS: If your IP be on the range, it will be ignored for the shoots. CAUTION: While this execution is on, all connection on the range will be out of comunication !!
