wget -N --no-check-certificate "https://raw.githubusercontent.com/dlxg/Linux-NetSpeed/master/tcp.sh" && chmod +x tcp.sh && ./tcp.sh

wget http://down.freenn.com/gz/fikkerd/fikkerd-3.7.6-linux-x86-64-crack.tar.gz
tar zxf fikkerd-3.7.6-linux-x86-64-crack.tar.gz
mv fikkerd-3.7.6-linux-x86-64 /usr/local/fikker
cd /usr/local/
chmod 777 -R fikker/
cd fikker/
./fikkerd.sh install && ./fikkerd.sh start
