default acquisition file leads to get ssh unparsed #2315

Closed sabban closed 2 months ago

sabban commented 1 year ago

What happened?

Default crowdsec configuration comes with the linux collection by default.

More and more distributions don't have auth.log and syslog file anymore, systemd's tool journalctl is used instead. Recently debian with the release of Bookworm did the move too.

Using the default acquisition file is still using only /var/log/syslog and /var/log/auth.log. This configuration doesn't lead to those file being parsed anymore, and having the default install this can lead to false sensation of protection .

What did you expect to happen?

By default and on most of linux distributions, linux collection and ssh scenario specifically should work out of the box. So I believe the default configuration file should include journalctl configuration as well.

How can we reproduce it (as minimally and precisely as possible)?

Default install in Bookworm using debian repository

Anything else we need to know?

Non working acquisition doesn't make crowdsec return anymore after those patches https://github.com/crowdsecurity/crowdsec/commit/a910b7becad1e06cb460949ab448d3172eb5679f and for 1.4 release branch https://github.com/crowdsecurity/crowdsec/commit/a0d69783cd284075881361a6ae84ad9531d3d420
