This will fix the root access by password (which should only be done for testing/non-production!) Ssh-keygen -t dsa -f /etc/ssh/ssh_host_dsa_key Ssh-keygen -t rsa -f /etc/ssh/ssh_host_rsa_key If it still doesn't work, you may need to manually recreate the server rsa and dsa keys The error above could be caused by this problem described here, where you will need to ensure that password auth is preferred before trying to use client side keys. Received disconnect from 192.168.1.205 port 22:2: Too many authentication failures for root It doesn't allow the user to attempt password authentication. SSH to the device doesn't work as root by default, you should create a separate user.

This assumes your default gateway is 192.168.1.1 If using a static IP you can set a static route for default gateway like this: If it's not the case you can set DHCP client for vlan 0 or whatever VLAN like this: It should show a list of fields like this: IP address Hardware address Type Lease expires at Here we use evil Google's free but tapped 8.8.8.8 nameserver as an example (run the command again to add more DNS servers). We still probably want things like gateway and DNS for our DHCP: Let's say we want to reserve 20.1.20.200 and up for static IPs we can do this: Set system services dhcp pool 20.1.20.0/24 This creates a DHCP Pool for the 20.1.20.0 subnet, however it does nothing unless you actually have an interface assigned with an iP from that subnet. #in most firmware you'll need to set a root password before you can commit DHCP Server/Pool Creation #if you already have DHCP on the network, I recommend deleting the DHCP service which may start handing out IPs by default Warning: activating factory configuration How Can You Get Info About the Hardware /model/serial number? Then commit the changes and the shell will now have your hostname. This means adding or deleting config options will not have any effect until you run "commit".
