gortcp

支持

• 内网穿透，灵感来源于rtcp。
• 文件上传
• 远程命令执行

Usage

• cmd/server/server.go 转发服务器
• cmd/client/client.go 内网机器
• cmd/control/control.go 控制终端

转发服务器运行：

./server -addr :33456 -auth 123456

内网机器运行：

./client -addr 10.68.102.49:33456

控制终端

查看连接的机器

⇒  ./control -addr 10.68.102.49:33456 -action list
|ID        |ADDRESS
|1         |10.68.102.48:49725

远程执行命令

在远程1号机器上执行命令

⇒  ./control -addr 10.68.102.49:33456 -action exec -id 1 -cmd "ping -c 4 baidu.com"

文件上传

上传本地的./control到远程1号机器的/tmp/test.bin

⇒  ./control -addr 10.68.102.49:33456 -action upload -id 1 -src ./control -dst /tmp/test.bin
send: 3300KB | time: 0.06S | speed: 56970KB/S
CLIENT: receive complete, md5 verify passed

端口转发

转发本地33060端口的数据到远程机器的3306端口，当然也可以是远程机器能连接的其他主机

⇒  ./control -addr 10.68.102.49:33456 -action forward -id 1 -laddr 127.0.0.1:33060 -raddr 127.0.0.1:3306
16-08-30 17:31:22.063 INFO @control.go:172 [tcp] listen on local 127.0.0.1:33060

连接本地的33060端口：

⇒  mysql -uroot -h 127.0.0.1 -P 33060
