5. Acronis Backup uses TCP ports 445 and 25001 for remote installation. Also, it uses TCP port 9876
for remote installation and for communication between the components.
Port 445 is automatically opened when you enable File and Printer Sharing. Ports 9876 and
25001 are automatically opened through Windows Firewall. If you use a different firewall, make
sure that these three ports are open (added to exceptions) for both incoming and outgoing
requests.
After the remote installation is complete, you can remove ports 445 and 25001 from exceptions.
Port 25001 is automatically closed through Windows Firewall. Port 9876 needs to remain open.
On machines running Linux
1. Make sure that the machines meet the system requirements (p. 16).
2. Check that each of the machines meets the prerequisites for local installation of Agent for Linux
(p. 39), except for the "Installation files" step.
3. Make sure that TCP port 22 is opened and that the SSH daemon is running on each of the
machines. After the remote installation is complete, you can close the port and stop the SSH
daemon.
4. Open TCP port 9876 on each of the machines. Acronis Backup uses this port for communication
between the components; therefore, it must remain open for both incoming and outgoing
requests.
