The VPCS can simulate up to 9 PCs. You can ping/traceroute them, or ping/traceroute the other hosts/routers from the virtual PCs when you study the Cisco routers in the Dynamips. VPCS is not the traditional PC, it is just a program running on the Linux or Windows, and only few network commands can be used in it. But VPCS can give you a big hand when you study the Cisco devices in the Dynamips. VPCS can replace the routers or VMware boxes which are used as PCs in the Dynamips network.

BWPing is a tool to measure bandwidth and response times between two hosts using Internet Control Message Protocol (ICMP) echo request/echo reply mechanism. It does not require any special software on the remote host. The only requirement is the ability to respond on ICMP echo request messages. BWPing supports both IPv4 and IPv6 networks.

360-FAAR (Firewall Analysis Audit and Repair) is an offline, command line, firewall policy manipulation tool to filter, compare to logs, merge, translate and output firewall commands for new policies, in Checkpoint dbedit, Cisco ASA or ScreenOS commands, and its one file! Read Policy and Logs for: Checkpoint FW1 (in odumper.csv / logexport format), Netscreen ScreenOS (in get config / syslog format), Cisco ASA (show run / syslog format), 360-FAAR compares firewall policies and uses CIDR and text filters to split rulebases / policies into target sections and identify connectivity for further analysis. 360-FAAR supports, policy to log association, object translation, rulebase reordering and simplification, rule moves and duplicate matching automatically. Allowing you to move rules to where you need them. Build new rulebases from scratch with a single 'any' rule and log files, with the 'res' and 'name' options. Switch into DROPS mode to analyse drop log entries.

BCU SDK is a C based, high level development system for creating programs for EIB/KNX BCU devices. It includes the GNU toolchain for the m68hc05 architecture (m68hc05-gcc, m68hc05-gdb, newlib). Bus access is possible using multiple methods.

New version 1.2. This is the code to STUNTMAN - an open source STUN server and client code by john selbie. Compliant with the latest RFCs including 5389, 5769, and 5780. Also includes backwards compatibility for RFC 3489. ICE and WebRTC ready. Version 1.2 compiles on Linux, MacOS, BSD, and Solaris. Supports the STUN protocol on both UDP and TCP for both IPv4 and IPv6. Windows binaries are also provided. Additional features are in development. This is a mirror of the code on https://github.com/jselbie/stunserver More details on the project's website: http://www.stunprotocol.org

Vortex Library an implementation of the RFC 3080 / RFC 3081, known as the BEEP Core protocol, mapped into TCP/IP layer and written in C.

Parallel Events and Asynchronous tasKing Library. Originally combining multi-threading with an efficient I/O event model, it's now more a lightweight object-oriented framework for event-based applications.

Returns external IP address. That is all! Details: program is written in .net but can be used as library also. Executable available here is for winXP or higher. but you can convert it to c# <http://www.developerfusion.com/tools/convert/vb-to-csharp/> or run on linux using mono (it is tested for mono compilation here <http://www.tutorialspoint.com/compile_vb.net_online.php> and works fine) so it should work using mono on OSX also. You are welcome to contribute compiled executable for other OS' - to simplify process there is only one file required for compilation. Although this is simple program it includes all options for reliable acquiring external IP address, because it not depends on single server but many; use -? parameter for help or -?? for many additional options.

MiXiM is a simulator for wireless and mobile networks using the OMNeT++ simulation engine.

sshh allows you to make a persistent tcp connection (tunnel) over an http proxy. Once you have it set up, you can make new connections from either end. Similar in concept to httptunnel but more versatile and scalable.

Hey. At work it was necessary to create a tool to monitor servers and computers, which must always be online. For these purposes the MassPinger was created. It supports many groups and many computers in groups. CrossPlatform (for Linux compiled but untested), written in Lazarus. Sources available on homepage.

VisualNMS is a network management system with powerful visualisation features due to its vectorial based rendering (SVG). It is built using perl, javascript, SVG, HTML. It includes Layer 2 autodiscovery based on LLDP and other discovery protocols (Cisco's CDP, Extreme Networks' EDP, etc.). Other features include: real time SVG graphs on links, web2cli engine (AJAX to Telnet/CLI), editable maps, auto layout (based esentially on GraphViz), VLAN mapping (work in progress) based on SNMP.
