Managed TFTP server is a TFTP server. The main TFTP class runs without modifications on Mono. It works both in IPv4 and IPv6 mode. It has correct retry behavior. It supports the following TFTP options: block size, transfer size, and timeout. It's possible to run in single port mode, which ensures that only port 69 will be used for TFTP transfers, simplifying firewall and router configuration. It supports many concurrent transfers. It runs as a Windows service. It supports multiple TFTP servers on different endpoints, each serving its own root directory. It has an advanced MSI-based installer. It logs to the windows event log. It has a permissive MIT license so it can be used in commercial projects.
Borderline is a firewall generator. It takes a generic rule specification as input and generated an highly optimized firewall. It features IPv6 rule generation, support for multiple interfaces, and integrated support for network zones. It currently only supports firewall generation for Linux 2.6 (netfilter).
smtp-cli is an SMTP command line client with support for advanced features such as STARTTLS, SMTP-AUTH, or IPv6. It also has scriptable message composition capabilities supporting anything from simple plain-text messages right up to building complex HTML emails with alternative plain-text part, attachments, and inline images. It's also a convenient tool for testing and debugging SMTP servers' setups. smtp-cli can be used to check a given server's capabilities, to test your server's setup, or to create and dispatch email messages. The command line interface is intuitive, and everything is scriptable and can run in a completely non-interactive mode from scripts or cron jobs. smtp-cli is ideal for shipping log files from remote machines, running periodic mail delivery test loops, etc.
IPv6 CARE, "IPv6 Compliant Automatic Runtime Environment", provides an environment where applications instantly become IPv6-compliant ('patch' mode, see RFC6535). It can also generate a diagnosis about the IPv6 compliance of an application ('check' mode). It uses an LD_PRELOAD-based library injection technique.
Traffic Squeezer is a Linux kernel based WAN network traffic accelerator from Doublefish Solutions. It uses methods such as traffic compression, traffic PDU coalescing, protocol specific acceleration (such as TCP acceleration mechanisms), and quality of service. Traffic Squeezer also contains custom L7filters (application protocol filters), DPI (Deep Packet Engines) and so on to control and administrate your traffic. With Traffic Squeezer, you can optimize MPLS,ISDN, leased links, Satellite Networks, and Marine Internet, and even build your own custom WAN Appliance with Traffic Squeezer. A GUI is now supported via Doublefish Solution Aquarium. Aquarium is a Web-GUI that also supports Traffic Squeezer, Squid, and other open source solutions.
Andrisoft WANGUARD is an enterprise-grade traffic monitoring and DDoS detection and protection solution that delivers the functionality NOC, IT, and security teams need to effectively monitor and protect their network through a single, integrated package. WANGUARD Sensor relies on sFlow, NetFlow, IPFIX, or Port Mirroring / SPAN.
RackTables is a tool to manage tens of racks, hundreds of servers, and thousands of MAC and IP addresses. It will work with a single rack as well. It features a real-life rackspace model, typed rack objects with flexible attribute sets, a tagging system, IP address management ready for NAT, virtual routers and load balancers, accurate network connection handling, a universal search function, a multi-user access model, and an extensible dictionary.
conexus is a generalized C++ I/O library that includes network support for IPv4 and IPv6 sockets, serial/TTY communications, kernel message queues, pipes, and files. Objects use sigc++ for signaling property changes and other information. Sub-libraries include conexus-gtkmm (provides a set of gtkmm widgets), conexus-dbus (provides dbus support for endpoints), conexus-nspr (provides NSPR endpoints), conexus-nss (provides NSS endpoints), and conexus-ssl (provides OpenSSL endpoints).
