I installed OpenSSH via tasksel and am using Webmin for administration. I'd like to be able to SSH externally and want to setup the necessary public/private keys to use in FileZilla.

In Webmin, under Servers > SSH Server I can click 'Host Keys' and see an RSA key. Is this the public or private key for my server? Do I need to copy this into a text file to import it into FileZilla on my remote PC (that I want to connect from)? Is that all that needs to be done (aside from opening the port on my router/firewall)?

Or, is there an automated way to set this up via Webmin?

Thanks

This site has a pretty comprehensive tutorial to ssh and webmin interactions.

Keep in mind however, your security is only as good as your weakest link and a lot of that for webmin and ssh is password quality and how well you keep your system up to date.

If you're running webmin, restrict access to it heavily.

Thanks for your reply. I see the option to generate keys when new users are added, is there a way to generate keys for a preexisting user from webmin?

You can do some from the command prompt just like you would on any other server, so long as the keys are in the right place with the correct names it should work fine.
