Apêndice A. Portas TCP e UDPcomuns
Esta tabela lista os números de porta TCP e UDP comuns , juntamente com os serviços ou protocolos normalmente associados a cada porta. As portas são identificadores numéricos que permitem que os computadores diferenciem entre vários serviços de rede em execução no mesmo dispositivo, facilitando a entrega correta dos pacotes de dados. A tabela inclui portas bem conhecidas, como a porta 80 para HTTP e a porta 443 para HTTPS, bem como portas usadas para transferência de arquivos (FTP), e-mail (SMTP, POP3, IMAP), gerenciamento de rede (SNMP) e muitas outras. Cada entrada especifica o protocolo de transporte suportado (TCP, UDP ou ambos) e descreve o uso típico ou aplicativo associado, fornecendo uma referência rápida para configuração de rede, solução de problemas e gerenciamento de segurança. Observe que P significa “Protocolo” em quase todas as siglas. A tabela inclui informações do PacketLife.net, do arquivo /etc/services, da minha experiência e da lista de portas da IANA.
