Crowdsec packages for OpenWrt

Héllo all,

Here is a PR for CrowdSec v1.1.1 and CrowdSec-FireWall-Bouncer v0.0.13

I still get an issue with ARM compile and buildroot…

Is there anyone who can help to fix this, please ?

UPDATE: now fixed and working !
UPDATE: Topic title changed from

Crowdsec: initial packages v1.2.0 for OpenWrt


This work is still an active development phase on OpenWrt...
As the wiki specific information on OpenWrt Wiki dedicated page.
CrowdSec is an attractive and innovative solution, so I understand you want to give a try, but you must look to the Official CrowdSec documentation if you need more than what is available to the OpenWrt packages where I try to made some end users and user friendly, but completely unsupported and personal but in progress additions !

So, Enjoy, use it at your own risks, or made it better by yourself.

How can I enable (force) a CONFIG value from a Package Makefile ?
Is it only possible to ?
I need the toolchain (binutils) to being built with EXTRA as :

CONFIG_EXTRA_BINUTILS_CONFIG_OPTIONS="--enable-gold --enable-plugins"

UPDATE : now unnecessary and fixed

Edit : made a PR to enable gold linker in binutils toolchain ->

UPDATE : now unnecessary and fixed

packages available now for testing also for mipsel_24kc ( like Device: Xiaomi R3P (mt7621)... )

UPDATE : now more up to date...

Now CrowdSec v1.2.0 and CrowdSec-FireWall-Bouncer v0.0.15

You can find the packages for testing at the Artifacts section from the build check of the PR section

seems to be from your uci-defaults/99_crowdsec last line;

cscli hub update && cscli collections install crowdsecurity/linux && cscli parsers install crowdsecurity/whitelists && cscli hub upgrade

edit: console finally exited after 2mins... how big is the download... (is interactive/uci-defaults the best way to handle this... firstboot internet connectivity might cause some issues here)

60M... slow servers maybe...

Thanks for the feedback…

It had some pre-install command integrated.
I must write a full OpenWrt documentation, but you may look at the default crowdsec documentations since I wrote OpenWrt specific…

The /srv/crowdsec must exist in a persistent storage.

I look at this ASAP…

Some initial commands may have been moved while PR reviews !
It need to be ready after installation, but I think there is no problem, since the Crowdsec package is not integrate in a firmware image for now.

afaik, we don't have /usr/local in OpenWrt

it may not be a default package... but it's not unreasonable to assume that people will attempt to include it by default when they create their own images...

the question(s) is(are);

  • how does the daemon behave when/if these commands fail on firstboot?
  • does the daemon / init script inform the user?
  • does the daemon / init script re-attempt?

Have you let the full install process be done ?

If you have interrupt the install, the initial commands will not have processed correctly !

Yes, it is why I have said I will look at your first report...

I may propose a crowdsec-data package to integrate the first install data download.

Or move this download further...

Or simply remove the first initial installation I have integrate in the package to simplify the usage for the user, and let him do all by itself reading the documentations...

It simply do not work since you remade the needed commands.
But some checks like in upgrade may bot work.

The log may, but the Init script don't.

No. not for now.

negative (your commands were all present at firstboot but failed because they run before any network interfaces are available)



Yes, and it is not used, or I have missing something...

I will patch to move this folder.

Update : To be fixed, it is a new feature from the v1.2.0 and I have missed this part !

I do not understand how you have installed the package ?
If you let it fully install and then reboot, is it okay ?

Because you have interrupt the install, the commands did not complete...

What the firstboot do here ?
The script is also apply at installation, and then uneeded at firstboot.
It will only be used at firstboot if you integrate the package in a custom firmware, what is it not supported for now, as I have already said.
