-# ipban
 
-A library for managing IP address bans on UFW systems
+# Library for the fail-ban function
+
+IPBan is a C++ library for banning IP addresses in case of consecutive errors.
+
+## Features
+
+- Object oriented
+- Thread safe
+- Internal database of banned addresses as a protection mechanism against irreversible ban
+- Automatic unbanning
+- Manual fail and unfail methods
+- White list of IP addresses
+- It is adjustable: database file location, tracking time for errors, number of attempts before ban, ban duration.
+## Installation
+
+This library also requires my exec library to work, download the latest release:
+
+https://git.bitelex.co/marcelb/exec or https://github.com/bandicm/exec
+
+Then download the latest backend of these libraries and unzip to the same location. You can turn it on with:
+
+```
+#include "cppurl/lib/cppurl.hpp"
+using namespace marcelb;
+```
+
+## Usage
+
+```c++
+//init
+ipban myban(30); // 30 minutes
+// add white list string or vector<string>
+myban.add_white_list("10.0.8.1");
+// ban now ip
+myban.ban("10.0.8.2");
+// fail ip
+myban.fail("10.0.8.3");
+// unfail ip
+myban.unfail("10.0.8.3");
+
+```
