Join Sean Colins for an in-depth discussion in this video Firewall-cmd configuration preparation, part of Linux: Firewalls and SELinux.
- [Instructor] This chapter's going to be a lot of fun,…because if you've got a Fedora server set up…and you're just trying to set up your basic firewall…so you can protect your server,…this is the chapter that's going to absolutely…make that happen for you.…To get started we're going to do some foundational stuff…in the first movie, right here,…which will impact the way things work…in future movies in the chapter.…So I highly encourage you,…whatever service you're trying to enable,…that you watch this movie in its entirety.…And that you follow along and do what I'm going to do.…
Not everything that I'm doing will be necessary,…but if you get out of place with where I am,…your mileage may vary whenever you're doing it on your own.…The first thing we're going to do here on our Fedora server,…and we're doing this entirely at the command line,…is we will log in…So type in your user name,…type in your password,…and you're in.…We're going to be making some modifications…that are definitely security related,…and will be protected by a sudo requirement,…
