performance hit in using too many if's

[Alt]

Hello,

You just need fail2ban and no need to know Perl. But you'll probably need to
know regular expressions.
Fail2ban can be adapted to most log format, but nginx logs format is the
same as apache, so it's easy :-)

I'm sure you can find many tutorials to explain how to install and configure
it by searching "fail2ban apache" or "fail2ban nginx".
