Updating from the Mirror

There are two basic methods to configure a Mirror, which is essentially a repository where clients can download update files. The folder with update files can be presented as a shared network folder or as an HTTP server.

Accessing the Mirror using an internal HTTP server

This is the default configuration specified in the predefined program configuration. To allow access to the Mirror using the HTTP server, navigate to Advanced setup > Update > Profiles > Update mirror and select Create update mirror.

In the HTTP Server section of the Mirror tab you can specify the Server port where the HTTP server will listen as well as the type of Authentication used by the HTTP server. By default, the Server port is set to 2221.

The Authentication option defines the method of authentication used for accessing the update files. The following options are available: None, Basic, and NTLM. Select Basic to use base64 encoding with basic username and password authentication. The NTLM option provides encoding using a safe encoding method. For authentication, the user created on the workstation sharing the update files is used. The default setting is None, which grants access to the update files with no need for authentication.

After your Mirror server is configured, you must add the new update server on client workstations. To do this, follow the steps below:

•Access Advanced setup (F5) and click Update > Profiles > Updates > Module updates.

•Disable Choose automatically and add a new server to the Update server field using one of the following formats:
http://IP_address_of_your_server:2221
https://IP_address_of_your_server:2221 (if SSL is used)

Accessing the Mirror via system shares

First, a shared folder should be created on a local or network device. When creating the folder for the Mirror, you must provide “write” access for the user who will save update files to the folder and “read” access for all users who will update ESET Endpoint Security from the Mirror folder.

Next, configure access to the Mirror in Advanced setup > Update > Profiles > Update mirror tab by disabling Enable HTTP server. This option is enabled by default in the program install package.

If the shared folder is located on another computer in the network, you must enter authentication data to access the other computer. To enter authentication data, open ESET Endpoint Security Advanced setup (F5) and click Update > Profiles > Updates > Connection options > Windows shares > Connect to LAN as. This is the same setting used for updating, as described in the Connect to LAN as section.

To access the mirror folder, this needs to be done under the same account as the one used for logging into the computer the mirror is created on. In case the computer is in a domain, "domain\user" username should be used. In case the computer is not in a domain, "IP_address_of_your_server\user" or "hostname\user" should be used.

After the Mirror configuration is complete, on client workstations set \\UNC\PATH as the update server using the steps below:

1.Open ESET Endpoint Security Advanced setup and click Update > Profiles > Updates.

2.Disable Choose automatically next to Module updates and a new server to the Update server field using the \\UNC\PATH format.

The last section controls program components (PCUs). By default, downloaded program components are prepared to copy to the local mirror. If Program component update is activated, there is no need to click Update, because files are copied to the local mirror automatically when they are available. See Update mode for more information about program component updates.
