SSH Authentication ================== The methods described here can also be configured via :doc:`/features/configmode`. Telnet access is only possible when booting into safe-mode. How boot into safe-mode is explained in the `openwrt wiki `_. SSH login will be possible after the start of dropbear, which is regularly performed when running in normal mode. Adding a password ----------------- Setting a password for any user on the Nodes - especially for root - is *not encouraged*. It comes handy, though, especially when logging in from via a remote machine that does not have your own SSH private key, e.g. directly from a gateway machine. But passwords are always too short or too easy to guess/brutforce and therefore mostly insecure. Always consider using SSH public keys. If setting a password via :doc:`/features/configmode` was disabled for security reasons, please: * boot into failsafe-mode * telnet the node on ``192.168.1.1`` * when connected:: $ mount_root $ passwd For users other than root, please perform as you would do with any other Linux machine. Adding SSH public keys ---------------------- If it is not possible to set a SSH public key via :doc:`/features/configmode`, you may use a temporary password or use the safe-mode to append your key to ``/etc/dropbear/authorized_keys`` manually. .. seealso:: For Information how to add SSH public keys to the images while compiling see :doc:`/features/authorized-keys`
