Getting “error: closed” twice on “adb reverse”

Question

I am trying to reverse-forward port through ADB, but it just returns cryptic error of error: closed. Normal forwarding works. Session snippet:

$         


        

Answer 1

cause of adb reverse isnt working on android prior 5 you could propably use adb forward with a service listening on android and tunneling other connections through this inbound connection. I am doing this mostly with ssh, but you would need an ssh server on android. you than can connect using ssh -R incommingreverseportonandroid:hostyouwanttoforwardto:portyouwanttoforwardto sshuseronandroid@localhost -p portyouhaveusedforadbforwaqrdtoaccessandroidssshserver

but i dont know how to enable an ssh server on android and maybe there is a better way cause ssh uses encryption which isnt needed over usb and using up cpu.

i am using this way with my server to share a service when i am forced behind a nat...

hope someone will find a way to bring this teoretical way into practical possibility
