For my Orange Pi PC, I just switched from the buggy debian-image to Armbian. Armbian works fantastic, but there is one small problem with my ssh reverse tunnel.

 

On the (old) debian system i had my script tunnel.sh:

#!/bin/bash
/usr/bin/autossh -p2000 -fNC -R 9000:localhost:9091 -R 5057:localhost:4949 -R 8000:localhost:8888 -R 10012:localhost:22 myusername@www.mydomain.com

The remote Pi will call my gateway Pi at port 2000. Whenever i call the gateway-ip:9000 i am at port 9091 on my remote pi etc.

Worked flawless.

 

After I changed to Armbian, this mini-script for tunnel.sh works, too:

#!/bin/bash
/usr/bin/autossh -p2000 -fNC -R 10012:localhost:22 myusername@www.mydomain.com

I can log in by SSH on port 10012 of my gateway Pi into my remote Pi.

But i can´t add the other ports from the example above. The Orange Pi PC will reboot ok, but I can´t even log in by SSH through port 10012 of my gateway Pi.

 

Any ideas, what i am doing wrong?

thanks for pointing @ autossh

 

if you still have a copy of your old system... check ssh_config & sshd_config to see if there are restrictions in sshd or ssh client config that you allowed and forgot to "backport"

i checked the file /etc/ssh/sshd_config for several times - not sure, what changed, but: perfectly working! thanks for your advice!
