How to install Fail2Ban together with Caddy?

Help

Hi everyone!

Is there any step by step guide how to install Fail2Ban together with Caddy? I have tried most of the guides that are online but didn’t manage to succeed. Can anyone help?

Thanks.

Howdy @Berian_Hoxha - don’t know about a step-by-step guide, but broadly speaking…

You need to download Caddy with the transform-encoder plugin, and configure logging in the common log format:

Once you’ve got that you can point Fail2ban at the CLF logs just like you would an Apache server.

I have tried and followed this step by step(tried three times), but I cannot manage to start it’s services. After installing and building it, where and how should the caddyfile be configured? Is it the same as installing the normal raw caddy?

Thanks,

Yep, it’s just normal Caddy but with an extra option for the encoder.

Quick crash course: Caddyfile Quick-start — Caddy Documentation
Longer tutorial here: Caddyfile Tutorial — Caddy Documentation
More in-depth info here: Caddyfile Concepts — Caddy Documentation

Run it as you would configure it normally, just add a logger that outputs Common Log Format as outlined in the caddyserver/transform-encoder Github page and point Fail2ban at that log.

Yes mate, I can install caddy normally and it will run fine. I am having issues installing xcaddy to run fail2ban. It seems that there is not any guide with all the steps. I have to combine several tutorials to install it but still not managing to make it run. Is there any specific guide for Xcaddy?

@Berian_Hoxha if you don’t tell us what problem you had installing xcaddy, how are we meant to help? Please show what you tried, paste the logs etc.

The xcaddy README (on github) has all the installation instructions you should need.

Please fill out the help topic template as per the forum rules. It’s necessary for us to efficiently help you.

Depending on how you install, you might probably just be able to download the binary from Download Caddy and tick the modules you want, without having to worry about xcaddy at all.

Or you might be able to run caddy add-package.

You haven’t filled out the template, though, so I don’t have any idea how you’re set up. Without that information, nobody’s going to be able to tell you what you need to do, only point you vaguely in the direction of some resources that might help, because there’s a million and one environments and methods you could be using to run Caddy in.
