Asuswrt device tracker not working with ssh login

Installation Home Assistant OS
1

For the love of god I cannot get asuswrt working on my RT-68 router running normal firmware.

THis is my configuration in config.yaml file. I can successfully login to router using putty and the certificate via ssh. I have no passphrase set for the certificate. Anyone can help???

Config.yaml

asuswrt:
  host: 192.168.1.1
  username: test123
  ssh_key: /config/ssh/privatenopass

Configuration of device_tracker.yaml

- platform: asuswrt
  host: 192.168.1.1
  username: test123
  ssh_key: /config/ssh/privatenopass

This is what i get as an error.

How did you generate /config/ssh/privatenopass? With putty? If so, you probably need to export it. Putty doesn’t generate keys in a format that’s usable by openssh. It works with putty because the format it gives you for the public key (which you installed on the router) is compatible.

Also, please note that ssh doesn’t work with certificates – it works with public and private keys. In the PKI world, a certificate usually contains a public key, and never a private key. The private key would be stored separately, although sometimes in the same file (which tends to confuse people). :slight_smile:

I did it with puttygen.

So if I understand right i have to convert the private key as an openssh key *using puttygen)?

That is correct.
