Crowdsecurity/rdns not adding reverse_dns to alerts

crowdsec
1

I have installed crowdsecurity/rdns, ensured that it is enabled and restarted crowdsec. However, after following guide, I still can’t whitelist hosts with a specific reverse DNS.

Also I would like to ask if it is possible to verify rDNS in postoverflow to confirm FCrDNS.

Hello,

Please provide more details about what you’re trying and what doesn’t work :slight_smile:
Maybe try turning your whitelists or the rdns postoverflow in debug mode.
