Hello, I have 2 systems, one as main router and a dumb ap, is there any way to ssh from main to dumb ap without main asking for password?

Thank you in advance

ps. Iam trying to automate a script, in some conditions of the dumb then a script in main should be executed.

You can use Dropbear key-based authentication.

Use the info here

https://openwrt.org/docs/guide-user/security/dropbear.public-key.auth

to generate your public key on the main router to be used in the authorized keys file on the ap

Although you could and it should be pretty easy to implement, I'd argue that you shouldn't do this. If someone gets access to your router, then they also have direct access to the AP. I usually try to isolate device access and only allow login from one main (hopefully secure) workstation, without a web of ssh credentials linking between various devices.

I use WireGuard on my phone to connect to my home WireGuard server, in two clicks I am connected.

I use connectbot on my phone to SSH into my console using keys so that it does not need a password on login a script is automatically executed which wakes up my server all with just one click.

This is my script, using etherwake to wake up:

#!/bin/sh
wu="$1"
[[ -z "$wu" ]] && wu="72:CF:22:218:8B:A4"
logger -p user.info -t "etherwake" "Sending Wake up to $wu"
etherwake -D -b -i br-lan "$wu"
