Solved Logging into SSH: How to set up/use [Authorized Keys] feature?

[Wallace_n_Gromit]

I thought I would try to set up SSH to login using [Authorized Keys]

I tried to find information using Search for "Authorized Keys" on snbforums. Didn't find anything specific as a step-by-step how to do this.

Has anyone tried using the PuTTygen app to set this up? I partially struggled my way through PuTTygen, copy and pasted the RSA Public Key into [Authorized Keys] field so it's on the router.

Logically, the matching key must be on the computer side/app side (i.e. putty). Dunno how that's done, the partial implicit directions are not intuitive.

When I SSH into the router it still asks for user name/password. (even after a reboot)

Oops!: I see something promising here: https://www.snbforums.com/threads/dropbear-ssh-without-remote-password.21070/

Using Putty, you need to go to Connection->SSH->Auth in the configuration, where you can Browse to find the Private Key.

It's also convenient to go to Connection->Data, where you can specify the username.

Of course, save the Session so you don't have to do this over and over again.

Thanks for those promising lead(s). I have a few errands to run, get back to this in a few hours. Expecting as much as 16" of snow next 2 days. Early light powder coming down now.

That helped especially watching the putty puttygen pageant youtube videos.

When I'm in Connection->SSH->Auth in the configuration I only see [About] [Help] [Open] [Cancel] I don't see a way to [Save] and NOT to keep having to [Browse] and keep finding/choosing the "Private key for authentication"

I have managed using Pageant to log in for the first time to my router just using my Username. Not sure yet if I lose everything with a reboot or computer shut down. Right now just playing around with it/trying different things. Kind of kewl! Regardless thanks for the leads. It really helped.

@Wallace_n_Gromit, you're welcome but you're not getting off that easily!

I'm waiting for your how-to guide, soon.

Yikes! My incompetent "How to" will be SURE way for me to get permanently banned from this site! It would be easier to write a "How NOT to..."

Why not? We already have too many how-to's! A how NOT to will be a refreshing change.

Under your home directory, there should be the .ssh directory (hidden), where the ssh client will typically look for the authorized_keys file, config file, etc. At least for the openssh client. Putty manages its own files under the .putty directory.
