Hi, I managed to configure rsa connection to dropbear and at the moment I can connect to my router using putty with key authentication(using private kay)
My question is how do I make windows CMD to use my private key and connect so I can create tunnels to local services on openwrt. I prefere CMD on windows 10 more than putty pls help
It appears to be a rather faithful port of the OpenSSH client, so yes -i would be your friend. There is probably also something equivalent to hiding a .ssh/id_rsa file (containing the private key which will then be automatically used) in your home directory.
As ssh-agent is available, that also lets you use a signed key (recommended by many) that you "enable" once for your session, rather than an unlocked key on the host.
