Boa noite pessoal.
Estou instalando o snort, no Free 5.4.
Ja intalei o snort-2.4.3_1, o mysql-server-4.1.15, criei a base de
dados no mysql e o usuarios.
Ao tentar rodar, ele apresentou varios erros, que eram dos arquivos
.sample, do qual renomei-os e os erros sumiram, mas agora observei que
outros erros estao sendo apresentados, como por exemplo diz que falta
o rules, mas nao achei nenhum diretorio com tal informação.
Gostaria de uma ajuda para rodar o snort.
Abaixo segue o log de erros que ele apresenta na tela.
