PICI-NMS is an object oriented middleware which makes possible sending messages in a networked environment or on a single host between applications using the library provided. The supported message sending mechanism is "publish/subscribe" and this is backed up by a very easy-to-use and intuitive C++ API which hides the underlying socket interface to make the message sending as transparent to the client as possible.
ctunnel is a program for tunneling and proxying TCP or UDP connections via a cryptographic tunnel. ctunnel can be used to secure any existing TCP or UDP based protocol, such as HTTP, Telnet, FTP, RSH, MySQL, VNC, DNS, XDMCP, NFS, etc. You can also chain or bounce connections to any number of intermediary hosts.
VncThumbnailViewer gives you the ability to connect to and watch multiple computers at the same time using the VNC protocol. It presents live thumbnail views of many computers in a single window, scaling and rescaling the views to best fit. Double-clicking on a single thumbnail allows you to enlarge it and take control of that computer's keyboard and mouse.
ns4 is a command line configuration management tool that runs on a Unix or Windows based operating system. It allows the automated backup of node (i.e. routers and switches) configurations to an FTP/SFTP server or local media on a daily basis to create configuration archives. It can run ad-hoc commands on multiple nodes as well as custom scripts for automating complex tasks. It uses Perl and allows you to manipulate the output of commands using regular expressions within scripts. Configuration based cartridges are used to specify new node types, allowing the user to extend its functionality in a simple and dynamic way.
Path Analyzer Pro integrates advanced traceroute software (based on the open-source tool LFT) with performance measurements, DNS, whois, and specialized network resolution to help investigate network issues. It also supports geolocation, and can plot network paths on a map. People use it to research IP addresses, email addresses, and network paths, to graph protocol latency, jitter, and other factors, and to locate firewalls and other filters that may be impacting your connections.
StableNet Express can comprehensively monitor an entire network, including the system and application environments. It features an easy-to-follow graphical display which provides a live view of what is going on in a networked IT system. The automatic discovery functions allow the entire monitoring system to be up-and-running within only a few minutes. Nothing needs to be installed on the production systems. It can be extended by users with their own measurement and alarm modules by adding scripts into a specific folder.
MCS MyVoIP very accurately measures the quality and performance of Internet connections for Voice over IP (VoIP) usage by simulating UDP voice data traffic between a server and browser clients. Connections are tested for jitter and packet loss and rated for the supported level of sound quality. The VoIP test can be set to various codecs or customized by packet size, packet rate, and test length. The test can further be combined with a bandwidth speed test or network route diagnostics for more in-depth connection analysis.
jNetStream is a sniffer and a protocol analyzer. A set of applications and complete Java library are provided with a comprehensive API. Hundreds of protocols have been defined, and the list can be expanded with a simple NPL language. It is appropriate for custom protocol development, grad students, and network teachers/professors.
