/etc/net represents a new approach to Linux network configuration tasks. Inspired by the limitations of traditional network configuration subsystems, /etc/net provides built-in support for configuration profiles, interface name management, removable devices, full iproute2 command set, interface dependencies resolution, QoS, and firewall configuration frameworks. /etc/net provides support for the following interface types: ethernet, WiFi (WEP), IPv4/IPv6 tunnels, PSK IPSec tunnels, VLAN, PLIP, ethernet bonding and bridging, traffic equalizer, Pent@NET, Pent@VALUE, SkyStar-2, TUN/TAP, OpenVPN TUN/TAP, usbnet, and PPP. Due to its modular structure, support for new interface types can be added without overall design changes.
AMaViS (A Mail Virus Scanner) scans e-mail attachments for viruses using third-party virus scanners available for UNIX environments. It resides on a UNIX (Linux) machine and looks through the attached files arriving via e-mail, generates reports when a virus is found and sets the delivery on hold.
The ATA over Ethernet Tools are intended for use in conjunction with an ATA over Ethernet (AoE) driver for a Linux 2.6 kernel, called "aoe". The tools perform simple tasks like listing available devices, triggering device discovery, and restricting the network interfaces on which AoE is performed.
Arno's IPTABLES Firewall Script is a secure stateful firewall for both single and multi-homed machines. It supports NAT and SNAT, port forwarding, ADSL ethernet modems with both static and dynamically assigned IPs, MAC address filtering, stealth port scan detection, DMZ support, protection against SYN/ICMP flooding, experimental IPv6 support, multi-interface/aliased-IP support, and extensive user definable logging with rate limiting to prevent log flooding. It has plugin support to add extra features (like SSH Brute Force protection and (Racoon) IPSEC support). It is easy to configure and highly customizable. A filter script that makes your firewall log more readable is also included.
BBStatus is an IP accounting package and an SNMP and IP monitoring tool for Linux. It collects, summarizes, and displays the values from its database. It can be used for IP accounting (allows you to design various kinds of accounting filters), SNMP monitoring (collects data making SNMP requests), ICMP monitoring (stores and summarizes values like min, avg, max reply time, and packet loss), and client traffic filtering (using various types of filters). It also provides user based access so that every user can log in and visualize various data (depending on access rights). It requires PostgreSQL, Apache with mod_auth_pgsql, Perl(Net::SNMP), and RRDTool.
The Bait and Switch Honeypot System combines the snort Intrusion Detection System (IDS) with honeypot technology to create a system that reacts to hostile intrusion attempts by marking and then redirecting all "bad" traffic to a honeypot that partially mirrors your production system. Once switched, the would-be hacker is unknowingly attacking your honeypot instead of the real data, while your clients and/or users are still safely accessing the real system. Life goes on, your data is safe, and you get to learn about the bad guy as an added benefit. It works with Snort 1.9.0, 1.9.1, and 2.0.2.
Bartlby is a network and system monitor, completely written in C, to provide a scalable framework with the ability to monitor networks of various sizes. It consists of a core daemon, several plugins, and a Web GUI (PHP extension). The core daemon checks (over active/passive TCP) services/hosts and notifies users in case of critical service conditions (mail, SMS, ICQ, and custom triggers are supported). Bartlby provides an open plugin interface to give every administrator an easy to use option to extend the plugin base, and a fully customizable GUI (written in PHP using a C extension). Nearby everything can be controlled via an XML interface.
BongoSurfer is a least-cost router for Linux, like the Smartsurfer program for Windows. It allows you to connect to the Internet with a 56k modem or ISDN, and chooses the cheapest provider for you. The tariff database is updated every day from http://www.billiger-surfen.de/. Since the tariffs only apply within Germany, the program is of little use in other countries. It features a cost calculator, a traffic monitor, an online timer, and more.
