  1. Enter a name to identify this configuration.
  2. Enter your device’s host name or IP address. See How to find the IP of your device.
    
    Your device and your host machine must be in the same network.
  3. Enter the device’s SSH port number; the default value is 22.
  4. Enter the username used to log in to the device; the default value is root.
  5. Click Next.
2. In the Key Deployment page:

How to find the IP of your device

You can find the IP of your device with the ifconfig command.

# ifconfig eth0
eth0      Link encap:Ethernet  HWaddr 00:40:9D:98:A6:37
          inet addr:192.168.42.30  Bcast:192.168.42.255  Mask:255.255.255.0
          inet6 addr: fe80::211:22ff:fe33:2211%lo/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:1071204 errors:0 dropped:0 overruns:0 frame:0
          TX packets:81475 errors:0 dropped:0 overruns:0 carrier:0
