How to disable SSH password login?

David W

Hi Omega Team,

I wana disable the root account login via SSH by password.
Could you tell how to do it?

I can not find the sshd config file at "/etc/ssh/sshd_config".

PubkeyAuthentication yes
// disable ssh text password login(private key file login only).
PasswordAuthentication no

Thank you!
David

Maybe it is not possible (for security reasons, I suppose)... Are you sure you want to do it?
I suggest to set up a key-based ssh login if putting every time the password is annoying to you.

Hi, is there a guide somewhere to setting up a key based login on the omega2?

$ uci set dropbear.@dropbear[0].RootPasswordAuth=0
$ uci commit dropbear
$ uci export dropbear
$ cat /etc/config/dropbear
$ /etc/init.d/dropbear restart
