Make Android phone accessible from a public server via reverse SSH tunnel. Useful for building DIY 4g/5g proxies, or any purpose related to remote administration of an Android device.
Use the build-shar.sh script to specify a host with the -c switch which the Android device should connect to on the port specified by -p (defaults 22) and expose its own localhost:8022 (8022 can be replaced with the -R switch) on that host. The RSA key specified with the -i flag will be packed into the shar so it is best to generate a new key for this. The authorized_keys file on the Android device can be supplied with the -a flag (defaults to ~/.ssh/id_rsa.pub)
bash ./build-shar.sh -c mydomain.dns.army -i ~/.ssh/id_rsa -a ~/.ssh/authorized_keysThis command will create a tundroid.shar file in the current working directory. Install Termux and Termux:Boot on an Android device then get the shar file on the device by some means. On the Android device run the command sh ./tundroid.shar and the device will be set up to automatically tunnel to the server specified when you built the shar file.
