What Ports Are Needed for Virtualization?
Virtualization is a technology that allows you to run multiple virtual machines on a single physical server. However, for virtualization to work correctly, you need certain ports on the server. Let’s find out which ports are needed for this process.
1. Port 22: SSH
SSH (Secure Shell) is a remote access protocol used to manage the server. To work with virtual machines via SSH, you need to open port 22 on the server.
2. Port 80 and 443: HTTP and HTTPS
HTTP (port 80) and HTTPS (port 443) are protocols used to transmit data over a network. To provide access to the web interfaces of virtual machines, you need to open ports 80 and 443.
3. Port 3389: RDP
RDP (Remote Desktop Protocol) is a remote desktop protocol that allows you to access the desktop of a Virtual Machine Templates: A Step-by-Step Guide" class="internal-post-link">Virtual Machine Backup in 2 Steps: A Quick Guide" class="internal-post-link">virtual machine. To work with RDP, you need to open port 3389.
4. Port 5900: VNC
VNC (Virtual Network Computing) is a remote access technology that allows you to control the desktop of a virtual machine. To work with VNC, you need to open port 5900.
5. Port 5432: PostgreSQL
PostgreSQL is a popular database management system. To work with a PostgreSQL database on a virtual machine, you need to open port 5432.
6. Port 1521: Oracle
Oracle is a powerful database management system. To work with an Oracle database on a virtual machine, you need to open port 1521.
In conclusion
Virtualization requires opening certain ports on the server for virtual machines to work correctly. Make sure that the necessary ports are open and configured correctly to avoid virtualization problems.
