Update mirror

Several ESET security products (ESET PROTECT, ESET Endpoint Antivirus, etc.) allow you to create copies of update files that can be used to update other workstations on the network. The use of a mirror— a copy of the update files in the LAN environment—is convenient because the update files do not need to be downloaded from the vendor update server repeatedly by each workstation. Updates are downloaded to the local mirror server and then distributed to all workstations to avoid the risk of network traffic overload. Updating client workstations from a mirror optimizes network load balance and saves internet connection bandwidth.

Configure ESET Server Security for Linux to use an update mirror

1.In the Web interface navigate to Setup > Update > Primary Server.

2.In the Basic section, click the toggle next to Choose automatically to turn it off.

3.In the Update server field, type the URL address of the mirror server in one of the following forms:

a.http://<IP>:<port>/<path_to_update_folder>

b.http://<hostname>:<port>/<path_to_update_folder>

4.Type the applicable username and password.

5.Click Save.

If there are more mirror servers available in your network, repeat the steps above to configure the secondary update servers.
