Notes: | ||
#### Notes: | ||
The rules applied to wings are fairly strict so if you feel like you need to adjust them, the settings are as follows | ||
Max retry is the number of failed attempts someone can do within the time defined in "findtime" before they are banned | ||
|
||
example: maxretry = 4 with findtime = 3600 with bantime = -1 | ||
|
||
this will allow 4 failed login attempts within 3600 seconds (1 hour) before permanently banning someone | ||
There are different time modifiers you can use, Most people will be using dd (day) mm (month) yy (year) | ||
I do suggest you read up on fail2ban docs, you can get highly customised protection from custom configuration | ||
