![]() The GeoIP firewall integration for iptable is now complete, commands can now be executed with the following syntax. Now load the GeoIP firewall module xt_geoip into memory with subsequent testing. The output appears similar to the following, here in abbreviated form. ![]() The CSV data is converted using the MaxMind CSV database converter to binary for xt_geoip. $ /usr/lib/xtables-addons/xt_geoip_build -D /usr/share/xt_geoip *.csv Upload the Country-CSV_20220125.zipfile to the server using ftp or scp, into the directory path /usr/share/xt_geoipand unzip it. The contents of the GeoLite2-Country-CSV_20220125.zip ZIP fileĬreate a new directory on the host and change to it. If you want to perform the download using, you need a license key, which you can generate under “My Account – Manage License Keys”, the download did not work here at this time (401 Unauthorized). Under GeoIP2 and GeoIP Legacy Databases – GeoLite2-Country-CSV Format with Download ZIP download the file. After signing in, go to My Account and Download Databases. MaxMind requires you to register for the Free Account with a valid email. MaxMind is a Massachusetts-based digital mapping company that provides location data for IP addresses. The GeoIP database must be downloaded from the MaxMind website, with the following URL. If you get abort E: Package iptables-dev has no installation candidatethen skip next MaxMind GeoLite2 and go to update. $ apt -y install curl unzip perl iptables-dev xtables-addons-common libtext-csv-xs-perl libmoosex-types-netaddr-ip-perl pkg-config The installation of the required services and libraries for GeoIP firewall on Debian and Ubuntu is done as root with “su -” or “sudo su -“. On the Internet, an IP address can be assigned to a country, a city or an organization in order to then determine the location. When tracking the sources of brute force and DDoS attacks, the sources are often found in the Far East and Russia.Ī geolocation system is used to determine the location of systems. In addition, further considerations should be made whether the accessibility of websites and services from countries far away from local languages is at all appropriate, and relations may not be maintained with distant regions, such as to South Pacific. On the other hand a "managed" VPS may have additional protections, when it is geared toward less technically proficient end users.In this Tutorial we show you how to deploy and use GeoIP with the kernel firewall of Debian 10 buster and Debian 11 bullseye or Ubuntu 20.04 LTS. I am assuming you have an "unmanaged" VPS, which means you are on your own and you have to protect yourself. Upstream traffic filtering should be minimal if any, but it is something you have to clarify with the webhost. So the fact that iptables is present does not necessarily mean it is the active firewall.Īnd since you mention it is a VPS: in addition to the built-in Linux firewall, the VPS may be sitting behind a hardware/software appliance of some sort, that acts as firewall or does DDOS mitigation. ![]() For example it is possible that someone replaced the default firewall with another firewall (firewalld, ufw) but that iptables is still installed. Which means that while it's not running it is available. If a firewall is already installed, chances are it's one of those: iptables, firewalld, ufw.Īttention: a service may be installed on your system but disabled. To list active services: systemctl list-units -type=service -state=active To list all loaded services on your system, including failed services: systemctl -type=service It is a good idea to review the default setup, because there may be services that you don't need, and you can disable them to improve performance, even reduce the attack surface (for example there may be a webserver running, that you don't need). ![]() I would have a look at the system services. ![]()
