Blocks IP addresses of specific organizations and companies that may harm user privacy when using the Internet and peer-to-peer networks.Here is a summary of the main features of PeerGuardian 2: Instead, it is better to allow specific IPs manually and do a proper investigation on any unknown IPs before allowing access. Also, although PeerGuardian 2 offers the option to allow connections over HTTP, this can be unsafe if you are not sure that none of your P2P or insecure applications use those ports. In addition, some users have reported problems with error detection and slow IP blocking speed. On Windows 98 or Me operating systems, it only blocks TCP, which means that other protocols will not be protected. However, this version has some disadvantages. It also includes an update tool that multitasks and can be canceled. In addition, it features a revamped user interface and a history viewer that allows the user to search for lists by name, enable/disable lists without having to delete them, and use the list cache to reduce load times. PeerGuardian 2 has been significantly improved compared to its predecessor and is very easy to use, thanks to its startup wizard. In addition, new management and reporting database systems allow users to play an active role in preventing friendly IPs from being blocked. It is possible to allow an individual IP address for some time or permanently, solving the problem of incorrect IP addresses. More detailed settings can be configured from the interface, including logging and the ability to prevent websites from being blocked. The new startup wizard makes everything more straightforward than ever. There is no need to install a driver just run the program without visiting the control panel. It was founded in early 2005 by and intended to be a platform-agnostic database using open-published formats. is a website that allows users to interact with and block IP addresses of specific organizations and companies. By default, it collects IP addresses from the website. PeerGuardian 2 blocks IP addresses based on a list of IP addresses collected by many methods. On Windows 98 or Me, it blocks only TCP (due to technical reasons, kernel-level blocking on 98/ME is not feasible) with the same high performance as the Windows 2000 version. On Windows 2000 and above, it blocks at the kernel level, acting against all protocols used within the Windows system. Unlike its predecessor, it does not require the installation of any drivers and blocks IP addresses much faster than before. To start pgl automatically at boot, enable the pgl service.PeerGuardian 2 is an IP filtering software designed to block the IP addresses of specific organizations and companies that may wish to harm the user's privacy while using the Internet and peer-to-peer networks. To make sure that pgl works as intended, issue this command: Once comfortable with the configuration of both the daemon and lists, start the pgl service. etc/pgl/nf WHITE_IP_OUT="192.168.0.0/24" /etc/pgl/nf WHITE_IP_IN="192.168.0.0/24"įor further information, please refer to the # Whitelist IPs # section of /usr/lib/pgl/faults. To disable this behavior, edit /etc/pgl/nf to add an exception using the WHITE_IP_* setting: etc/systemd/system//nf īy default, pgl blocks traffic on the local IPv4 addresses. To ensure adequate protection, extend the unit rvice with the following: Systemd initialization of the system means that it is quite possible for a server to be briefly unprotected, prior to pgl launch. The following example only use the block lists to stop incoming traffic on ports 53 (DNS) and 80 (HTTP): etc/pgl/nf WHITE_TCP_OUT="http https"Ĭonversely, one could white list all the ports except the ones used by the program to be blocked. It is recommended to disable the filtering of HTTP connections by adding the following to /etc/pgl/nf: Users are encouraged to exercise best judgment and the information available at I-Blocklist. The default lists in /etc/pgl/blocklists.list block many potentially legitimate IP address. /etc/pgl/allow.p2p lists custom IP ranges that will not be filtered./etc/pgl/nf, empty by default, overrides the default settings present in /usr/lib/pgl/faults./etc/pgl/blocklists.list contains a list of URL for retrieving the various block lists. There are two possible packages to install: pgl-cli AUR includes only the daemon and CLI tools, while pgl AUR comes complete with a GUI (written using Qt). pgl is based on the Linux kernel netfilter framework and iptables.Ī more native, efficient solution to achieve the same end is to use the ipset kernel module in conjunction with the pg2ipset tool and the ipset-update script. It blocks connections to and from hosts specified in huge block lists (thousands or millions of IP ranges). PeerGuardian Linux ( pgl) is a privacy oriented firewall application.
