aquando da realização duma captura de pacotes num dos interfaces do servidor deparei-me com o seguinte problema:

4 packets captured
575 packets received by filter
557 packets dropped by kernel

a resposta a este problema encontrei-o no fórum cuja ligação deixo em baixo.

começamos por descarregar a versão estável do sofware:
sudo curl -L "https://github.com/docker/compose/releases/download/1.28.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

fazemos o ficheiro executável:
sudo chmod +x /usr/local/bin/docker-compose
