Since dropbear stores its keys in different format, it needs to be converted for a standard SSH server:ĭropbearkey -y -f ~/.ssh/id_rsa grep “^ssh-rsa ” > authorized_keys The goal is to allow ‘nas’ to authenticate to ‘webhost’ using a key instead of a password.įirst, generate your identity key on ‘nas’ This assumes that the OpenWRT device is named ‘nas’ and the remote machine is ‘webhost’. I found plenty of examples on setting up key based authentication using dropbear as the HOST, but not as the CLIENT. In order to rsync files from a remote host using a cron script, this is critical. It turns out that the dropbear ssh client works a bit differently when attempting to use key based authentication. I ran into a little bit of a hiccup getting my OpenWRT NSLU2 device to automatically rsync to a remote host. $ dropbearconvert openssh dropbear iddsa dbiddsa. The ssh private key can then be converted into a dropbear key using the dropbearconvert utility, either built from the sources or installed via e.g.
