Administrative ports
Some administrative ports are required to configure votre instance GitHub Enterprise Server and run certain features. Administrative ports are not required for basic application use by end users.
| Port | Service | Description |
|---|---|---|
| 8443 | HTTPS | Secure web-based Management Console. Required for basic installation and configuration. |
| 8080 | HTTP | Plain-text web-based Management Console. Not required unless TLS is disabled manually. |
| 122 | SSH | Shell access for votre instance GitHub Enterprise Server. 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. |
| 1194/UDP | VPN | Secure replication network tunnel in high availability configuration. Required to be open for communication between all nodes in the configuration. |
| 123/UDP | NTP | Required for time protocol operation. |
| 161/UDP | SNMP | Required for network monitoring protocol operation. |
Application ports for end users
Application ports provide web application and Git access for end users.
| Port | Service | Description |
|---|---|---|
| 443 | HTTPS | Access to the web application and Git over HTTPS. |
| 80 | HTTP | Access to the web application. All requests are redirected to the HTTPS port if TLS is configured. |
| 22 | SSH | Access to Git over SSH. Supports clone, fetch, and push operations to public and private repositories. |
| 9418 | Git | Git protocol port supports clone and fetch operations to public repositories with unencrypted network communication. Si vous avez activé le mode privé sur votre instance, l’ouverture de ce port n’est nécessaire que si vous avez également activé l’accès en lecture Git anonyme. Pour plus d’informations, consultez « Enforcing repository management policies in your enterprise ». |
Avertissement : Quand des connexions HTTPS se terminent sur un équilibreur de charge, les demandes de l’équilibreur de charge vers GitHub Enterprise Server doivent également utiliser HTTPS. Le passage de la connexion HTTPS à HTTP n’est pas pris en charge.
Email ports
Email ports must be accessible directly or via relay for inbound email support for end users.
| Port | Service | Description |
|---|---|---|
| 25 | SMTP | Support for SMTP with encryption (STARTTLS). |
GitHub Actions ports
GitHub Actions ports must be accessible for self-hosted runners to connect to votre instance GitHub Enterprise Server. For more information, see "À propos des exécuteurs auto-hébergés."
| Port | Service | Description |
|---|---|---|
| 443 | HTTPS | Self-hosted runners connect to votre instance GitHub Enterprise Server to receive job assignments and to download new versions of the runner application. Required if TLS is configured. |
| 80 | HTTP | Self-hosted runners connect to votre instance GitHub Enterprise Server to receive job assignments and to download new versions of the runner application. Required if TLS is not configured. |
If you enable automatic access to GitHub.com actions, GitHub Actions will always search for an action on votre instance GitHub Enterprise Server first, via these ports, before checking GitHub.com. For more information, see "Enabling automatic access to GitHub.com actions using GitHub Connect."
GitHub Connect ports
If you enable GitHub Connect, the connection between GitHub Enterprise Server and GitHub.com uses HTTPS over ports 443 or 80, and TLS is required. For more information, see "About GitHub Connect."
