基于Frp的内网穿透，校园网外ssh访问实验室服务器

Reference: Access your computer in a LAN network via SSH.

On server A (in the LAN):

• set up frp client:

  1 2 3 4

  wget https://github.com/fatedier/frp/releases/download/v0.53.2/frp_0.53.2_linux_amd64.tar.gz tar -zxvf frp_0.53.2_linux_amd64.tar.gz cd frp_0.53.2_linux_amd64 nano frpc.toml

  1 2 3 4 5 6 7 8 9 10

  # frpc.toml serverAddr = "43.139.224.203" # public IP serverPort = 7000 [[proxies]] name = "ssh" type = "tcp" localIP = "127.0.0.1" localPort = 1220 remotePort = 6000

  • Make 6000 and 7000 accessible: sudo ufw allow 6000 andsudo ufw allow 7000 .

• run frp client by

  1	./frpc -c ./frpc.toml

  or

  1	nohup ./frpc -c ./frpc.toml &

  If any conflicts:

  1	pkill -f frpc

On server B (with a public ip address):

• set up frp server:

  1 2 3 4

  wget https://github.com/fatedier/frp/releases/download/v0.53.2/frp_0.53.2_linux_amd64.tar.gz tar -zxvf frp_0.53.2_linux_amd64.tar.gz cd frp_0.53.2_linux_amd64 nano frps.toml

  1 2	# frps.toml bindPort = 7000

• run frp server by

  1	./frps -c ./frps.toml

  or

  1	nohup ./frps -c ./frps.toml &

  if any coflicts:

  1	pkill -f frps

On your computer oustide the LAN containing server B:

1

ssh -oPort=6000 lasso@43.139.224.203
