Radarcape:Miscellaneous

Using SOCAT to copy TCP to a file

 socat -u TCP:localhost:10002 OPEN:radarcape.bin,creat

Tunneling a port to another Radarcape

First, generate a SSH key pair on the local Radarcape

cd ~/.ssh
dropbearkey -t rsa -f id_rsa

Set attributes of ~, .ssh and authorized_keys are set to 600.

Next, copy the public key given from above command to the server folder ~/.ssh/authorized_keys. Mind that the attributes of ~, .ssh and authorized_keys are set to 600. On the local Radarcape, add the command below to cape.sh. Please remember that cape.sh runs without user settings, so you need to specify the path to the SSH key absolute.

./autossh -M 6667 -f -p <server_ssh_port> -i /home/root/.ssh/id_rsa -N -R *:8002:localhost:80 -R *:1302:localhost:10003 -R *:2202:localhost:22 root@<server_domain> & 

Now the local Radarcape is accessible on <server_domain> under port 8002, 1302 and 2202.

Server Settings

If the server is also a Radarcape, and in case that you want to get access from external devices to the ports through the tunnel, you need to add switch "-a" to the dropbear startup file /lib/systemd/system/[email protected].
