I have a linux device with a dropbear running on it. I want to use the device as SSH client only, and not allow any SSH connections to it.
In order to do it, I added this line to the config file: DROPBEAR_ARGS='-p 127.0.0.01:22'
This seems to do the job. now i wonder if it is secure enough. Is it a good practice? is there a tricky way for someone to connect to my device anyway?
