Installing optional packages for the SOAR Platform

You can install optional Linux® packages on your SOAR Platform.

Before you begin

Before you install the optional packages, you must first complete the upgrade procedure, as described in Changed in 51.0.8.0 Upgrading the SOAR Platform. If the optional package was not downloaded with the upgrade package, go to IBM® Support Fix Central to download the optional packages.

About this task

You can install the following optional packages.

container-selinux: Install container-selinux if you plan to also install the App Host on the same system as the SOAR Platform.
lsof: You can use lsof to display files, including network files like network socket, and the processes that opened them.
lsyncd: You can use this tool to synchronize a source directory with one or more local and remote directories.
net-snmp: You can use Net-SNMP to use and manage the SNMP protocol.
net-snmp-utils: The net-snmp-utils package contains utilities to use with Net-SNMP. Use this package if you want these utilities to manage your network with the SNMP protocol.
openvpn: This tool uses a custom security protocol that uses SSL/TLS for key exchanges. It is open-source software that implements virtual private network (VPN) techniques for creating secure point-to-point or site-to-site connections in remote access facilities.
rsync: You use rsync to synchronize files on remote and local systems and to copy files to remote systems and back again, or to create backups to locally mounted hard disks.
tmux: You can use tmux as a terminal multiplexer to create, access, and control a number of terminals from a single screen. tmux can be detached from a screen and continue to run in the background, and then later reattached.
tcpdump: The tcpdump program is a data-network packet analyzer that displays TCP/IP and other packets that are transmitted or received over a network.
zip: You can use this tool to archive file format that supports lossless data compression.

Complete the following steps to install the optional packages that you want to use.

Procedure

Start the run file with a command similar to the following, where <yyyy-MM-dd_HH-mm> is the timestamp of the optional packages .run file:
For Red Hat® Enterprise Linux 8:
```
sudo bash ./soar-optional-packages-repo-rhel8-<yyyy-MM-dd_HH-mm>.run
```
It creates or updates a new local Yum repository called resilient_optional.
Use Yum to install the packages that you want, as shown in the following example.
```
sudo yum --noplugins install rsync
sudo yum --noplugins install net-snmp
```
You can verify the packages that you installed with commands similar to the following example.
```
rsync --version
snmpd --version
```
If you are installing container-selinux, enter the following command.
```
sudo yum --noplugins install container-selinux
```
