Sobre o arquivo config

=> O arquivo config podem ter quatro divisões :

  • [Options] : essa é uma seção especial para os protocolos (em especial o ICMP)

    • Sintaxe especial: ping_<reply/request>_<input_output>: <allow/deny/drop>
  • [Kernel] : as opções aqui são/devem ser arquivos do diretório /proc/sys/net/ipv4

    • Caso a ação for yes, o arquivo terá seu valor=1 e se for no = 0
  • [Port] : configurações de porta, pode estar protegido por portknock ou não

    • Caso esteja: ports_portknock: | Ex. ports_portknock: 111,222,333
      • E após isso especificar que porta quer proteger, Ex. portknock: 21,22
    • Caso não esteja, a sintaxe é essa: <allow/deny/drop>_<input/output>_<protocolo>: <portas>
  • [Protect] : é um caso especial, são algumas proteções que o Kull permite que você use, eis uma lista :

    • syn-flood: <yes/no>
