Platform Example
dd-wrt
Netgear WNDR4300 (Firmware: DD-WRT v3.0-r37882 std (11/30/18))
GOOS=linux GOARCH=mips GOMIPS=softfloat go build -a -ldflags '-s -w'
Usage
Start a server at a public server ( example.com ):
./otunnel listen -d
Start a client (reverse forward):
./otunnel connect example.com:10000 -d -t r:LOCAL_HOST:LOCAL_PORT::REMOTE_PORT
Now, anyone can access your LOCAL_HOST:LOCAL_PORT
by example.com:REMOTE_PORT
.
SystemD
In the server side (listen a port) , create /etc/systemd/system/otunnel-listen.service
:
[Unit]
Description=Otunnel Listen Service
After=network.target
[Service]
Type=simple
Restart=on-failure
ExecStart=/usr/local/bin/otunnel listen :20000 -d -s THE_SECRET
[Install]
WantedBy=multi-user.target
start otunnel-listen
service:
systemctl start otunnel-listen
In the client side, create /etc/systemd/system/otunnel-connect.service
:
[Unit]
Description=Otunnel Connect Service
After=network.target
[Service]
Type=simple
Restart=on-failure
ExecStart=/usr/local/bin/otunnel connect YOUR_SERVER_IP:20000 -d -s THE_SECRET -t "r:127.0.0.1:22::50022"
[Install]
WantedBy=multi-user.target
start otunnel-connect
service:
systemctl start otunnel-connect
Docker
Run a server:
docker run --rm -it --net=host ooclab/otunnel-amd64 /otunnel listen :10000 -d -s abc123
Run a client:
docker run --rm -it --net=host ooclab/otunnel-amd64 /otunnel connect SERVER_IP:10000 -d -s abc123 -t 'f:127.0.0.1:10022:HOST_IP:HOST_PORT'
