&lt;p&gt;&lt;b&gt;Página nova&lt;/b&gt;&lt;/p&gt;&lt;div&gt;Na minha máquina local vi que uma porta desconhecida estava aberta, a 111&lt;br /&gt;
 111/tcp open  rpcbind &lt;br /&gt;
&lt;br /&gt;
Normalmente se uma porta esta aberta é porque algum serviço esta usando… ai desligamos pelo /etc/init.d/aplicativos stop. Ou desativo ao inicializar usando gerenciador rcconf.&lt;br /&gt;
&lt;br /&gt;
Para os aplicativos que não são daemons, normalmente ficam para o gerenciamento do inetd. No debian usamos o comando update-inetd para habilitar, adicionar, desabilitar serviços que estejam rodando pelo inetd. Ficaria algo como:&lt;br /&gt;
 # update-ined -disable imap4 &lt;br /&gt;
&lt;br /&gt;
para fechar o serviço de imap4.&lt;br /&gt;
&lt;br /&gt;
Não consegui fechar por daemon nem inetd. Então usei o comando fuser para me dizer quem tava usando:&lt;br /&gt;
 root@camito:/home/banto# fuser -v 111/tcpUSER        PID ACCESS COMMAND&lt;br /&gt;
 111/tcp:             daemon     2441 F…. portmap &lt;br /&gt;
&lt;br /&gt;
poderia matar usando o comando kill:&lt;br /&gt;
 # kill -9 2441 &lt;br /&gt;
&lt;br /&gt;
mas resolvi filtrar a porta com iptables:&lt;br /&gt;
 # ipatbles -A INPUT -p tcp –dport 111 -j DROP &lt;br /&gt;
&lt;br /&gt;
mais ai meu kmail parou de funcionar. ai descobrir que em /etc/services existe uma lista com as portas e que aplicativo usa.&lt;br /&gt;
&lt;br /&gt;
Para voltar a funcionar o kmail bastou limpar as regras do iptables:&lt;br /&gt;
 iptables -F&lt;br /&gt;
 iptables -t nat -F&lt;br /&gt;
 iptables -t mangle -F &lt;br /&gt;
&lt;br /&gt;
Ai fui ver como anda a integridade do sistema, em busca vulnerabilidade, de rootkit, backdoor, sniffer e exploit scanner.&lt;br /&gt;
 # apt-get install rkhunter&lt;br /&gt;
 # rkhunter -c &lt;br /&gt;
&lt;br /&gt;
a única falha que ele achou foi o arquivo de configuração do sshd com permissão de acesso via root ;)&lt;br /&gt;
&lt;br /&gt;
vi algumas coisas novas.. o comando abaixo é possivel saber que aplicativo está usando determinada porta&lt;br /&gt;
&lt;br /&gt;
