Não é possível obter a saída do netconsole

  • 772

nc -l -u 6666 na máquina receptora não recebe mensagens do netconsole.

testado fazendo "teste de eco > /dev/kmsg"

consigo me conectar ao netcat fazendo "nc -u 10.0.0.192 6666" na máquina netconsole

"sudo tcpdump -i wlp170s0 -n -e porta 6666" não gera nada na máquina de escuta

opções do netconsole:

modprobe netconsole [email protected]/enp8s0,[email protected]/54:14:f3:52:82:94 oops_only=0

ifconfig na máquina netconsole:

    Acontece que você tem que aumentar a verbosidade com dmesg -n 8
