Join Sean Colins for an in-depth discussion in this video Allowing a PostgreSQL server, part of Linux: Firewalls and SELinux.
- [Narrator] When we get into services…that are much less common…or at least are less well known to system administrators…by their port numbers.…Because we don't interact with the port numbers…very frequently, it can be really useful to have the list…of services in front of us again.…This is just one of those examples.…PostgreSQL is a database that you can set up…on a Linux system and if you have done so,…it is conveniently packaged in one area here.…
PostgreSQL is just right there.…But there's also MySQL or MS SQL that are also available.…These are different but similar.…So I'm just going to assume that we're doing stuff…with SQL and Postgres databases, and I'm going to give you…the three services that I think you would want to add…into your default zone, if you were going to be…trying to allow imports for these specific services.…So let's go up to, "Add Service."…So we're just up arrowing at this point in the chapter.…
We are doing firewall-command,…or -cmd, to be specific.…space--add-service=…just to speak that out for you…
