Crowdsec finally comming to pfSense

provels

Is CrowdSec meant to replace pfB? Snort, Suricata? Augment them? Thanks.

@provels You can read here:

"https://www.crowdsec.net/blog/suricata-vs-crowdsec"

I think Crowdsec blacklist working the same as pfBlockerNG, THE POINT of this, that pfBlockerNG limited to one hour update maximum , Crowdsec update more frequently I think!

Looks like the pfSense install is not supported in FreeBSD 15 (24.03-RELEASE upgrade). Sad face.

@provels this? https://github.com/crowdsecurity/pfSense-pkg-crowdsec/releases/download/v0.1.3/freebsd-15-amd64.tar

@mmetc Not sure at present. I saw Crowdsec was uninstalled by the upgrade process when I upgraded yesterday and saw an OS mismatch when I tried to reinstall, hence my post. But there is a pfSense update issued overnight with the following log:

The following 3 package(s) will be affected (of 0 checked):

Installed packages to be REMOVED:
	re2: 20231101

Installed packages to be UPGRADED:
	pfSense: 24.03 -> 24.03_1 [pfSense]

Installed packages to be REINSTALLED:
	abseil-20230125.3 [pfSense] (ABI changed: 'freebsd:14:x86:64' -> 'freebsd:15:x86:64')

So maybe fixed, don't know yet.

Edit: Same errors as yesterday.

[24.03-RELEASE][root@fw.workgroup]/root: pkg add -f /root/CrowdSec/re2-20231101.pkg

Edit2: So I guess it's working even after mismatch messages. Probably the reason for this line in the install instructions. What do I know, I'm just some hack who will install anything! :)

# setenv IGNORE_OSVERSION yes

@provels you can download the archive I linked, there is the same content as the *pkg files but for freebsd 15. A new release with crowdsec 1.6.1 should be uploaded soon, I'll make sure to build the *pkg files with version 15

Antibiotic

@provels New release there for Freebsd15 and updated to 1.6.1

@mmetc Hello after install 1.6.1 on 24.03 have this error
level=error msg="while fetching bouncer info: ent: bouncer not found" ip=127.0.0.1

For pfSense+ 24.03_1 (amd64) I was following this steps;

Getting started - Install CrowdSec on pfSense

Please scroll down until you read the following (in a blue image)
You will see it here below in the code block
It is the install sequence (from top till down)

# setenv IGNORE_OSVERSION yes
# pkg add -f <link to abseil>
# pkg add -f <link to re2>
# pkg add -f <link to crowdsec-firewall-bouncer>
# pkg add -f <link to crowdsec>
# pkg add -f <link to pfSense-pkg-crowdsec>

And under this page you find the latest pkg´s or files for your installation.
pfSense-pkg-Crowdsec, click on assets (11) and the drop down menue is opening then right click on the shown links and past them in the following sequence inside of your pfSense console CLI.

Connect to your console
type in (8) for shell
and now all commands together (one after one) with the right link to the packages

As an example for pfSense+ 24.03_1 (FreeBSD 15) amd64 hardware shown below:

# setenv IGNORE_OSVERSION yes
# pkg add -f https://github.com/crowdsecurity/pfSense-pkg-crowdsec/releases/download/v0.1.3-1.6.1/abseil-20230125.3.pkg
# pkg add -f https://github.com/crowdsecurity/pfSense-pkg-crowdsec/releases/download/v0.1.3-1.6.1/re2-20240401.pkg
# pkg add -f https://github.com/crowdsecurity/pfSense-pkg-crowdsec/releases/download/v0.1.3-1.6.1/crowdsec-firewall-bouncer-0.0.28_3.pkg
# pkg add -f https://github.com/crowdsecurity/pfSense-pkg-crowdsec/releases/download/v0.1.3-1.6.1/crowdsec-1.6.1.pkg
# pkg add -f https://github.com/crowdsecurity/pfSense-pkg-crowdsec/releases/download/v0.1.3-1.6.1/pfSense-pkg-crowdsec-0.1.3.pkg

After installing it you may have a look under system > services > CrowdSec
to ensure that all is right enabled. If not enable (activate) them by clicking
on it, please click then at last on save

Now you should read the rest of the page
Getting started - CrowdSec on pfSense
to configure your installation, matching well to your network setup.

And at least activate both services to make them running.

I'm currently on version 1.6.0. To upgrade, should I execute only the following commands? Other than the re2 and pfsense packages, it appears that the remaining packages are the same version.

setenv IGNORE_OSVERSION yes
pkg add -f https://github.com/crowdsecurity/pfSense-pkg-crowdsec/releases/download/v0.1.3-1.6.1/re2-20240401.pkg
pkg add -f https://github.com/crowdsecurity/pfSense-pkg-crowdsec/releases/download/v0.1.3-1.6.1/crowdsec-1.6.1.pkg

Is there any breaking changes I should be aware of? I'm running pfSense CE 2.7.2....thanks.

provels

@mmetc FWIW, the crowdsec-1.6.0_1.pkg in the tar linked above worked fine for me.

https://github.com/crowdsecurity/pfSense-pkg-crowdsec/releases/download/v0.1.3/freebsd-15-amd64.tar

However, the 1.6.1 package linked below pretty much blew up my system

https://github.com/crowdsecurity/pfSense-pkg-crowdsec/releases/tag/v0.1.3-1.6.1

Caused a lockup on installation and save, Apparently ZFS saved my butt, directories below the root folder vanished, system eventually rolled itself back to mid-December. Perhaps a coincidence, but for me it was a mess.

EDIT - Ok, since I love hitting myself in the head with a hammer, I tried again... System crashed out shortly after, threw me back to 23.09 deleted my saved logs after 12/7 and threw a bunch of error's. Someone else can test, I've had it.

@bthoven

I attempted to upgrade only those two packages initially. After the upgrade, Crowdsec ceased to function, and even pressing 'save' on the settings page without making any changes, to force a restart, did not help.

Subsequently, I performed the complete 5-package upgrade following the sequence outlined in the documentation, but it still failed to start.

Ultimately, rebooting my pfSense resolved the issue, and it began working.

In previous upgrades of earlier versions, I recall never having to reboot my pfSense. It's strange.

provels

Continuing my self-abuse, I have found that the 1.6.0 version works fine on 24.03-RELEASE AFAICT even though it's compiled for Freebsd 14. Both the 1.6.0_1 and 1.6.1 will crash out and fubar the system. Think I'll wait for the Netgate Seal of Approval.

@provels Did you test last one 1.6.1_1 released 9 hours ago?

provels

@Antibiotic No, I can wait. You first!

Antibiotic

O_O)))

provels

@Antibiotic No idea. I hadn't even heard of it before this thread.

Yes, would be great if it is 'officially' supported by Pfsense.

Antibiotic

Hello, any info about official support of this package?
