Netconsole requires two machines, the one that is +panicky (source) and the one that will receive crash logs (target). The +source has to be connected with an ethernet cable and the target has to be +reachable at the time of the panic. To set this system up, execute the +following commands as root on the source (`source#`) and normal user on +the target (`target$`): + +1. Start a listener server on the target machine (netcat works well): + + `target$ nc -u -l -p 6666` + +2.
