I feel like I might have confused OpenSSH with firewall tools in the past. It’s more about secure connections, right?

I think IPChains was mentioned in a practice question we did, but I also recall IPTables being more commonly used in later versions.

I remember studying about firewalls and their functions, but I'm not entirely sure which tool specifically works with the Linux 2.4 kernel.

Ah, I remember learning about this in class! I believe the correct answer is HXDP 4.0.1, as that's the version where Cisco HyperFlex AII-NVMe nodes were first supported.
