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.
xllmnrd is an IPv6 LLMNR responder daemon (primarily for GNU/Linux operating systems). It allows Microsoft Windows clients to get the IPv6 address of a server on the same local network without any DNS configuration and effectively complements IPv4-only NetBIOS name resolution provided by Samba.
pcapfix is a repair tool for corrupted pcap and pcapng files. It checks for an intact pcap global header and packet block and repairs it if there are any corrupted bytes. If a header is not present, one is created and added to the beginning of the file. It then tries to find pcap packet headers or packet blocks, and checks and repairs them.
BGPHist is a tool that receives MP-BGP updates, decodes them, and writes them to a database for logging and monitoring purposes. It supports not only Internet routes, but also IPv4 VPN, IPV6 VPN, and L2VPN. It sounds text output, MySQL databases, and Oracle databases. For the MySQL backend, there is also a simple PHP frontend. It could be used to monitor and log an ISP's customer activity for Internet and VPNs, as a passive BGP looking glass, or as a backend for some external monitoring and accounting system.
Endian Firewall is an all-in-on Linux security distribution that turns any system into a full-featured security appliance. It features a stateful packet inspection firewall, application-level proxies for various protocols (HTTP, POP3, SMTP), anti-virus support, virus and spam filtering for email traffic (POP and SMTP), content filtering of Web traffic, and a "hassle free" VPN system based on OpenVPN.
Simple Packet Sender (SPS) is a Linux packet crafting tool. It supports IPv4, IPv6 including extension headers, and tunneling IPv6 over IPv4. It does not require pcap. It features packet crafting and sending one, multiple, or flooding IPv4 and IPv6 packets of type TCP, ICMP, or UDP (or cycling through all three). All values within an Ethernet frame can be modified arbitrarily. It supports IPv4 header options, TCP header options, and TCP, ICMP, and UDP data as well, input from either a keyboard as UTF-8/ASCII, a keyboard as hexadecimal, or from a file. IPv6 support includes hop-by-hop, "first" and "last" destination, routing, authentication, and encapsulating security payload (ESP) extension headers. For those without access to a native IPv6 network, IPv6 packets can be transmitted over IPv4 (6to4). Packet fragmentation is available for IPv4, IPv6, and 6to4. The assumed maximum transmission unit (MTU) can be changed if unusual fragment sizes are needed. IP addresses and port numbers can be randomized.
