Disable reverse DNS lookups for log entries

[simplydch]

Hi there,

I'm having a bit of a problem with malicious actors and having trouble limiting them with fail2ban, I think this is because log entries are hostnames rather than IPs and the IP fail2ban returns from its DNS lookup. Is there a way to disable the reverse DNS lookup and always print the IP address in the logs?

--numeric or equivalent in the configuration file? 30 nov. 2024 09:46:26 Darren Hunter ***@***.***>:
