Question Firewall rule to block bots

[SalvadorS]

Server operating system version

Debian 12

Plesk version and microupdate number

18.0.61

Hello Everybody,

We have a bot called claudebot who is hitting very hard a site. This bot has 1300+ different IPs, so my question is:

It is possible to block a bot in the plesk firewall by his name for example?

Something like if UserAgent contains claudebot then block.

Thank you in advance

Or if you know how to block a bot in a plesk server for all websites let me know

I think it can be done with fail2ban, it requires some customizations, see the next links for details

• How to Avoid High CPU Load & Block Bad Bots with Plesk
• fail2ban and openlitespeed · fail2ban fail2ban · Discussion #3745 (has an example of definition for "claudebot").

I second @AYamshanov's suggestion. Fail2ban would be the right tool for this.

Thank you. The articles are very interesting and I will test it.

Only one question, fail2ban an plesk firewall are compatibles?
