I just ran into an issue with CSF. I was doing some networking research over the past few days and learned that `iproute2` (called `ip` in CentOS 7) replaces the long deprecated `net-tools` package. I had manually installed the net-tools package quite a while ago for some network debugging. But now that I was switching over to using `ip`, I manually removed the net-tools package from the box. However, it turns out that CSF still depends on `ifconfig`, even though `ifconfig` has been deprecated for quite a while. It also turns out that CentOS 7 decided `net-tools` had been deprecated long enough, and quit including it. So it has to be manually installed anyway. Can I request switching to another more modern firewall/firewall configuration tool? For example, I know a lot of folks are happy with Shorewall--commonly recommended on ServerFault. Obviously not an immediate thing as it's a bit of work to switch out, but as a long-term goal project it'd be a nice upgrade. Continuing to use a tool (especially security tool) that relies on linux packages that have been deprecated for nearly 7 years (source: net-tools future) is asking for trouble.
