Rsync-bpc is a customized version of rsync that is used as part of BackupPC, an open source backup system. The main change to rsync is adding a shim layer that emulates the system calls for accessing the file system so that rsync can directly read/write files in BackupPC's format. Rsync-bpc is fully line-compatible with vanilla rsync, so it can talk to rsync servers and clients. Rsync-bpc serves no purpose outside of BackupPC.

This is a server daemon, port scanner and (optionally) clients for FSP, the File Service Protocol. FSP is lightweight and connectionless. It is typically used for offering files to "anonymous" visitors over a congested link. It uses UDP rather than TCP sockets. A service contact port (well-known port) for FSP has not been assigned by IANA (per RFC 1700). See <URL:http://www.faqs.org/faqs/fsp-faq/> for an overview. To use fspd, you must copy the fspd.conf.sample file, normally installed in /usr/local/etc/, to fspd.conf and edit it. You can run fspd from inetd or stand-alone.

This project contains all the necessary code to connect, send and receive messages to/from an AMQP-compliant peer or broker (Qpid, OpenAMQ, RabbitMQ) using Twisted. It also includes support for using Thrift RPC over AMQP in Twisted applications.

Paraphrasing the original (2.0) website: ZSI, the Zolera SOAP Infrastructure, is a Python package that provides an implementation of SOAP messaging, as described in The SOAP 1.1 Specification. In particular, ZSI parses and generates SOAP messages, and converts between native Python datatypes and SOAP syntax. ZSI, the Zolera SOAP Infrastructure, is a pure Python module that provides an implementation of the SOAP 1.1 specification. Simple client and server support are also provided.

This is a pure-python TCP load balancer. It takes inbound TCP connections and connects them to one of a number of backend servers. Features: - async i/o based, so much less overhead than fork/thread based balancers. Can use either twisted or python's standard asyncore library (twisted is recommended, and asyncore support will be removed in a future version). - Multiple scheduling algorithms (random, round robin, leastconns, leastconns+roundrobin) - If a server fails to answer, it's removed from the pool - the client that failed to connect gets transparently failed over to a new host. - XML based configuration file (see a sample) - separate management thread that periodically re-adds failed hosts if they've come back up. - optional builtin webserver for admin (sample of the running screen) - webserver has methods suitable for both interactive and automated systems

Quagga is a routing software suite, providing implementations of OSPFv2, OSPFv3, RIP v1 and v2, RIPv3, BGPv4 and experemental ISIS for Unix platforms, particularly FreeBSD and Linux and also NetBSD, to mention a few. Quagga is a fork of GNU Zebra which was developed by KunihiroIshiguro. The Quagga tree aims to build a more involved community around Quagga than the current centralised model of GNU Zebra.

RUDE stands for Real-time UDP Data Emitter and CRUDE for Collector for RUDE. RUDE is a small and flexible program that generates traffic to the network, which can be received and logged on the other side of the network with the CRUDE. Currently these programs can generate and measure only UDP traffic. Actually these tools were designed and coded bacause of the accuracy limitations in the MGEN program.

With the exponential growth of the Internet, a central Whois database that provides host and network information of systems connected to the Internet, and electronic mail (email) addresses of the users of those systems has proven to be very inefficient. The sheer size and effort needed to maintain a centralized database necessitates an alternate, decentralized approach to storing and retrieving this information. RWhois is a Directory Services protocol which extends and enhances the Whois concept in a hierarchical and scaleable fashion. It focuses on the distribution of "network objects"--the data representing Internet resources or people--and uses the inherently hierarchical nature of these network objects (domain names, Internet Protocol (IP) networks, email addresses) to more accurately discover the requested information. RWhois synthesizes concepts from other, established Internet protocols to create a more useful way to find resources across the Internet. The RWhois protocol and architecture derive a great deal of structure from the Domain Name System (DNS) [RFC 1034] and borrow directory service concepts from other directory service efforts, primarily [X.500]. The protocol is also influenced by earlier established Internet protocols, such as the Simple Mail Transport Protocol (SMTP) [RFC 821] for response codes.

TCPSG is just a simple TCP port forwarder designed to distribute a service like a virtual server. It can be used to protect servers using the port forwarder to receive requests.

Virtual Distributed Ethernet is a user-mode virtual network (layer 2) infrastructure. It can be used for network simulations, joining multiple qemu instances together in a shared virtual network, or tunneling over the Internet. Physical hosts can be joined to the virtual network by means of the tap(4) driver.
