The WiKID Strong Authentication System is a highly scalable, secure two-factor authentication system. It is simple to implement and maintain, allows users to be validated automatically, requires no hardware tokens, has a simple API for application support (via Ruby, PHP, Java, COM, Python, etc.), supports multiple domains, and supports replication for fault tolerance and scalability. It also supports mutual /host and transaction authentication, wireless tokens only domains, locked tokens (to your PC), anti-keystroke logger keypad PIN entry, etc.
Linux Bandwidth Arbitrator allows beginning-to-advanced network administrators to control bandwidth. It is designed to be completely turn-key in its default configuration. You just plug it into your network trunk, and it self configures and immediately starts slowing "bandwidth hogs". It can be configured to target specific applications such as Kazaa, IMAP, and POP. It is compatible with the 2.4.25 kernel, ebtables, and brouter (bridging router). It also comes with denial of service protection.
ClarkConnect is a powerful yet easy-to-use server/gateway software solution designed for the small/medium-sized organization. The software provides all the necessary server tools to run an organization: email, antivirus, antispam, file sharing, groupware, VPN, firewall, intrusion detection/prevention, content filtering, bandwidth management, multi-WAN and more.
Radiator RADIUS server is flexible, extensible, and authenticates from a huge range of authentication methods, including Wireless, TLS, TTLS, PEAP, SQL, proxy, DBM, files, LDAP, NIS+, password, NT SAM, Emerald, Platypus, Freeside, TACACS+, PAM, external, OPIE, POP3, EAP, MOTP, TOTP, HOTP, Active Directory, Vasco Digipass, SecurID, Yubikey, WiMAX, and many more. It runs on Unix, Linux, Solaris, Windows, MacOS 9, MacOS X, VMS, and more.
IPTables-tutorial is a tutorial which explains how to install and set up iptables and netfilters on Linux. It takes you through a usable example file step by step, and helps you understand its basic functionality. The tutorial currently contains 6 different example scripts that may be used freely under GPL licensing terms.
RANCID (Really Awesome New Cisco confIg Differ) collects a router's (or device's) configuration, including software and hardware (cards, serial numbers, etc.), and uses CVS to display differences from a previous collection. It supports Cisco routers, Juniper routers, Catalyst switches, Foundry switches, Redback NASs, and ADC EZT3 muxes. The Beta version currently includes support for Bay Networks (nortel) routers and Extreme switches. Rancid also includes a lookingglass and the device login scripts may be used to automate a number of tasks.
screen-scraper is a tool for extracting data from Web sites. It works much like a database that provides access to the information of the Web. It provides a graphical interface allowing you to designate URLs, data elements to be extracted, and scripting logic to traverse pages and work with scraped data. Once these items have been created, screen-scraper can be invoked from external languages such as .NET, Java, PHP, and Active Server Pages. It can be scheduled to scrape information at periodic intervals, and can automatically write extracted data to CSV files.
APSR is a network testing tool designed to send and receive arbitrary network packets. Its main purposes are firewall, security, routing, and a lot of other tests. It can also be used to analyze your network. The project is split into three main programs: apsend to create and send packets, aprecv to dump the network traffic, and the apsrlib which provides the appropriate low-level functions. A very wide range of protocols are supported by the aprecv program. The application layer is implemented through modules using a simple API. Modules can be written in Perl, Ruby, C, or PCL (a special-purpose packet construction language).
Akeni LAN messenger is a cross-platform instant messenger client. It is a P2P program that works on your LAN without the need of an Internet connection or a dedicated server. The client has an user interface similar to AIM, ICQ, or MSN Messenger. It supports all the standard IM features such as chat, group conference, presence management, file transfer, and emergency alert/notification. Extra features include contact management and optional tabbed chat sessions.
NetSQUID is a Perl script (daemon) that sits in between Snort and IPTables. It gathers alerts generated by Snort, then automatically creates an IPTables firewall entry to block the alerting host (such as those infected by viruses). Web traffic is redirected to a Web server that can alert the user to the infection. The host is automatically unblocked after a specified time. It can also send DHCP address requests, so rogue DHCP servers can be detected by Snort.
