Remote access ports are used for secure and efficient remote access to computer systems and networks. These ports are critical for remote administration, support, and management of systems. Here are some commonly used remote access ports and their associated services:
- Port 22: SSH (Secure Shell) – SSH is a secure protocol for remote access to Unix-based systems. It provides encrypted communication for secure shell sessions.
- Port 23: Telnet – Telnet is an older, less secure protocol for remote access to computer systems. It is less commonly used today due to its lack of encryption.
- Port 3389: RDP (Remote Desktop Protocol) – RDP is used for remote access to Windows systems, allowing users to control a remote desktop.
- Port 5900: VNC (Virtual Network Computing) – VNC is a protocol for remote desktop sharing. Port 5900 is the default for the VNC server.
- Port 5985 and 5986: WinRM (Windows Remote Management) – WinRM is used for remote management and scripting on Windows systems. Port 5985 is for HTTP, and port 5986 is for HTTPS.
- Port 25565: Minecraft Server – While primarily used for gaming, this port is also an example of remote access for managing game servers.
- Port 50000-50059: SAP GUI – The SAP Graphical User Interface (SAP GUI) uses a range of ports for remote access to SAP applications.
- Port 5901: VNC Alternate – An alternative port often used for VNC server communication.
- Port 3388: Remote Desktop Gateway – Used in some configurations of Remote Desktop for secure access.
- Port 2222: SSH Alternate – An alternative SSH port often used for secure remote access.
- Port 3385: RDP Alternate – Sometimes used as an alternative to the default RDP port (3389).
- Port 8443: HTTPS Alternate – Port 8443 is sometimes used for remote access via HTTPS.
- Port 4125: Remote Desktop Web Access – Used for web-based access to Remote Desktop services.
- Port 1194: OpenVPN – OpenVPN is a popular VPN solution that uses port 1194 for secure remote access.
- Port 443: HTTPS – While not exclusively for remote access, it’s often used for secure web-based remote access.
- Port 27017: MongoDB – MongoDB, a NoSQL database, may use this port for remote access and management.
- Port 2083/2087: cPanel – cPanel, a web hosting control panel, uses these ports for web-based remote access.
These remote access ports are vital for system administrators, support staff, and remote users to securely and efficiently access and manage computer systems and networks from a distance. The choice of port often depends on the specific service or protocol used for remote access
