Instale o nmap :
apt-get update
apt-get install nmap
Uso:
nmap 127.0.0.1
nmap ip apache
Vai te falar se as portas estão abertas ou fechadas.
A saida do comando : (Vai mostrar se o INPUT esta liberado)
iptables -L
Basicamente seria isso:
## Estabelece relação de confiança entre maquinas da rede local eth0(rede local)
iptables -A INPUT -i eth0 -s 192.168.0.0/255.255.255.0 -j ACCEPT
iptables -A INPUT -i eth0 -m state --state NEW -j ACCEPT
iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
André, tentei os dois primeiros passos o 1º funcionou certinho e diz que a porta 80 esta aberta para o http, mas o segundo nao funcionou, segue abaixo as linhas se puder me ajudar, obrigado.
