# Learning more about iptables: Is this Slicehost instance any kind of excellent?

To prepare to at some point release my first internet site, I've been having fun with Ubuntu Lucid Server in a VM on my WinXP equipment. I've been rotating in between the Linode and also Slicehost tutorials/articles for advice, and also I'm attempting to understand the area on iptables.

Slicehost's instance can be located here. It appears stealthily straightforward to me, however. It's simply an issue of securing down every little thing and also punching really details openings. When all various other write-ups appear complex and also make iptables seem like a massive PITA, this instance appears really uncomplicated (or at the very least, it appears in this way once you recognize what the commands suggest).

Is this instance ideal for a manufacturing web server? Do the actually difficult littles iptables just actually show up later on?

Depends significantly on your demands. iptables can be fairly very easy to master, when you recognize just how it functions.
There are 3 chains in the filter table which contain regulations : INPUT, OUTPUT and also FORWARD. If you're desiring to obstruct just packages entering into your web server, after that the INPUT chain is all you actually require to be worried concerning.
Usually, for standard INPUT filters, you'll locate just a couple of openings punched for the solutions that are necessary, after that an international catch-all that obstructs every little thing else. The instance Slicehost offers is an example of this.
