Network ports

Open network ports selectively based on the network services you need to expose for administrators, end users, and email support.

Administrative ports

Some administrative ports are required to configure your GitHub Enterprise Server instance and run certain features. Administrative ports are not required for basic application use by end users.

8080HTTPPlain-text web-based Console de gerenciamento. Not required unless SSL is disabled manually.
122SSHShell access for your GitHub Enterprise Server instance. Required to be open to incoming connections between all nodes in a high availability configuration. The default SSH port (22) is dedicated to Git and SSH application network traffic.

Application ports for end users

Application ports provide web application and Git access for end users.

PortServiceDescription
443HTTPSAccess to the web application and Git over HTTPS.
80HTTPAccess to the web application. All requests are redirected to the HTTPS port when SSL is enabled.
22SSHAccess to Git over SSH. Supports clone, fetch, and push operations to public and private repositories.
9418GitGit protocol port supports clone and fetch operations to public repositories with unencrypted network communication. Se você habilitou o modo privado na sua instância, abrir esta porta só é necessário se você também habilitou o acesso de leitura anônimo do Git. Para obter mais informações, consulte "Aplicar políticas de gerenciamento do repositório na sua empresa".

Aviso: Ao encerrar conexões HTTPS em um balanceador de carga, as solicitações do balanceador de carga para GitHub Enterprise Server também precisam usar HTTPS. O downgrading da conexão para HTTP não é suportado.

Email ports

Email ports must be accessible directly or via relay for inbound email support for end users.

PortServiceDescription
