This role manages the SSH service. OpenWrt uses dropbear in contrast to many other system, that use OpenSSH.
This is an example dropbear configuration:
openwrt_dropbear_passwordauth: "on"
openwrt_dropbear_rootpasswordauth: "on"
openwrt_dropbear_port: "22"
You can provide your OpenWrt devices with public keys. You can do that for a specific host, by defining this variable in your Ansible host definition:
openwrt_dropbear_keyshost:
- "ssh-rsa AAAAB3NzaC1yc2EAAAAyourpublickey9Y100zBxWp0= user@hostname"
When you would like to have keys provided to multiple systems you need to use an Ansible group. Define in the allhosts scope. This example assigns the keys to the group name platforms_openwrt:
openwrt_dropbear_keysgroup:
platforms_openwrt:
- "ssh-rsa AAAAB3NzaC1yc2EAAAAyourpublickey9Y100zBxWp0= user@hostname"
- "ssh-rsa AAAAB3NzaC1ya2EEAByourpublickey9Y100zB2xWp0= user2@hostname"
More parameter are supported, see:OpenWrt dropbear docs.
