DebWrt Netconsole

DebWrt by default includes netconsole for devices with no normal serial interface. With netconsole it is possible to have all kernel boot messages ( not the messages from init and initscripts! ) forwarded over the network to a remote computer. eth0 is used as interface to forward messages from. Note that eth0 may vary from device to device.

Settings

  • Embedded device: 6665@192.168.1.1/eth0
  • Remote computer: 6666@192.168.1.2

Remote computer setup

  • configure the LAN port on the remote computer connected to the eth0 on the device with:
    • ip: 192,.168.1.2
    • netmask: 255.255.255.0
    • no default gw
  • use netcat to listen to any packets on port 6666 and dump contents to the console
    • nc -u -p 6666 -l
