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.


  • Embedded device: 6665@
  • Remote computer: 6666@

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:
    • no default gw
  • use netcat to listen to any packets on port 6666 and dump contents to the console
    • nc -u -p 6666 -l
