## Prerequisites

•The computer must be reachable from the network.

•openssl—ESET PROTECT Server 13.1 and later supports OpenSSL 3.x, and does not support OpenSSL 1.x. ESET Management Agent supports both OpenSSL 3.x and OpenSSL 1.x—The minimum supported version of OpenSSL for Linux is openssl-1.0.1e-30, but we recommend using the latest version of OpenSSL 1.1.1. There can be more versions of OpenSSL installed on one system simultaneously. At least one supported version must be present on your system.

o Use the command openssl version to show the current default version.

o You can list all versions of OpenSSL present on your system. See the filename endings listed using the command sudo find / -iname *libcrypto.so*

o Verify if your Linux client is compatible using the following command: openssl s_client -connect google.com:443 -tls1_2

oFollow the Knowledgebase article to upgrade OpenSSL 1.1.1 to OpenSSL 3.x.

•Install the lshw package on the client/server Linux machine for the ESET Management Agent to report the hardware inventory correctly.

Linux distribution | Terminal command
--- | ---
Debian, Ubuntu | sudo apt install lshw -y
Red Hat, Rocky Linux | sudo yum install lshw -y
SUSE Linux Enterprise Server | sudo zypper install lshw

•For Linux CentOS, we recommend installing the policycoreutils-devel package. Run the command to install the package:

yum install policycoreutils-devel

## Installation

Perform the Installation of the ESET Management Agent component on Linux using a command in the Terminal.

|  | The communication protocol between Agent and ESET PROTECT Server does not support authentication. Any proxy solution used for forwarding Agent communication to ESET PROTECT Server that requires authentication will not work.

Follow the steps below for Agent installation on a Linux workstation.

1.Download the Agent installer script to the client computer.

2.Extract the .sh file from the .gz archive: tar -xvzf PROTECTAgentInstaller.tar.gz

3.Set the ESET Management Agent installation .sh file as an executable: chmod +x PROTECTAgentInstaller.sh

4.Execute the .sh file or run the Terminal command: sudo ./PROTECTAgentInstaller.sh

5.When prompted, type the local administrator password and press Enter.

6.After the Agent installation completes, run the following command in the Terminal window to verify that the Agent is running: sudo systemctl status eraagent

7.The computer with the installed Agent will appear in your ESET PROTECT Web Console, and you can manage it using ESET PROTECT On-Prem.

|  | If the computer with the installed Agent does not appear in your ESET PROTECT On-Prem, perform troubleshooting.

|  | ESET PROTECT On-Prem supports the automatic upgrade of ESET Management Agents on managed computers.
