Dropbear, public key authorization and multiple users



  • Currently, I can login using to my Omega2+ using an RSA key, but I can only do it as root.

    I have now added an ordinary user to passwd, shadow and group. I've created an ordinary /home directory for the user, setup it in passwd, fixing permissions, etc. Can I use dropbear to also login as this user, or do I need to replace dropbear with an openssh-server to achieve this?

    If I can use dropbear, where do I put the public key? For root, I have put it in /etc/dropbear/authorized_keys (and this works).



  • It seems from the config file parameters that you can login as a user. Maybe the config file is bad? The dropbear doc is rare, but maybe this will help:

  • Just to close the loop in case anyone else finds this.

    I found it worked using the standard location, ~/.ssh/authorized_keys.

    I used puttygen (Windows) to create the key and pasted it in there.

    There is a dropbearkey program that will let you create keys on the Omega2+ in case you want to ssh FROM the Omega2+ to, say GitHub/Gitlab...
