System Prerequisites:
CySight includes all core service RPMs (MySQL, Java, Tomcat, backend engines), but your OS must have several system packages installed.

Required System Components – Summary

These packages are checked and installed by check_env.sh to ensure the system is compatible with CySight — especially on minimal or hardened OS builds.

firewalld, iptables-nft, nftables
Used to open necessary ports (e.g., UDP 2055, 6343) during setup.
CySight does not manage firewalld directly, but check_env.sh ensures it is installed and enabled to allow flow traffic.
policycoreutils, policycoreutils-python-utils
Required for managing SELinux modes and boolean flags (e.g., allowing MySQL services to run).
Helps maintain secure SELinux enforcement while allowing CySight components to operate normally.
libaio, libaio-devel
Libraries required by MySQL to support high-performance asynchronous I/O.
Necessary for compatibility on hardened or minimal systems where these may be missing.
python3-firewall, python3-gobject, python3-gobject-base
These support firewalld’s CLI tools on systems that rely on Python/DBus backends — even though CySight does not interact with DBus directly.
Included to prevent CLI command failures on minimal systems where these are missing.
cairo, python3-cairo, glib2, gobject-introspection
Transitive dependencies required by firewalld's Python utilities.
Needed to ensure compatibility with `firewall-cmd` and other system tools during the environment check.
telnet
Used by check_env.sh to confirm that flow sources can reach the server.
Helps validate inbound network paths during installation.
perl and related modules
Some legacy system utilities, logging tools, or pre-check scripts rely on Perl.
Included to improve compatibility across varied EL9 minimal install profiles.

If your system is connected to the internet, these packages will be installed automatically using system repositories.
Note: In air-gapped environments, these packages must be pre-installed or made available via local repositories or RPMs.

Java and MySQL Conflict Detection:

Existing Java or MySQL packages will be listed if detected.
No automatic removal is performed for safety reasons.
In interactive mode, you’ll be prompted to review and manually uninstall if needed.
Non-interactive shells will log a warning and continue installation.

Post-Install Configuration:

Apply your license key (emailed upon registration).
Refresh the browser UI to activate features.
Start sending NetFlow/IPFIX or enable cloud-based log ingestion.
Monitor live dashboards as data flows in.
