The librsync library implements network delta-compression of streams and files. The algorithm is similar to that used in the rsync(1) and xdelta(2) programs, but specialized for transfer of arbitrary-length octet streams. Unlike most diff programs, librsync does not require access to both of the files on the same machine, but rather only a short ``signature'' of the old file and the complete contents of the new file.

ngrep strives to provide most of GNU grep's common features, applying them to the network layer. ngrep a pcap-aware tool that will allow you to specify extended regular expressions to match against data payloads of packets. It currently recognizes TCP, UDP, and ICMP across Ethernet, PPP, SLIP, FDDI, Token Ring and null interfaces, and understands BPF filter logic in the same fashion as more common packet sniffing tools, like tcpdump and snoop.

Various modules for use Sockets with a TIESCALAR interface for really simple socket communications. Net::Gen - generic sockets interface handling Net::Inet - Internet socket interface module Net::TCP - TCP sockets interface module Net::TCP::Server - TCP sockets interface module for listeners and servers Net::UDP - UDP sockets interface module Net::UNIX - UNIX-domain sockets interface module Net::UNIX::Server - UNIX-domain sockets interface module for listeners

This module provides a perl interface to the Twitter APIs. It uses the same API definitions as Net::Twitter, but without the extra bells and whistles and without the additional dependencies. Same great taste, less filling. This module is related to, but is not part of the "Net::Twitter" distribution. It's API methods and API method documentation are generated from "Net::Twitter"'s internals. It exists for those who cannot, or prefer not to install Moose and its dependencies.

Yadis is a service discovery system allowing relying parties (aka identity consumers or membersites) to determine automatically, without end-user intervention, the most appropriate protocol to use. Examples of such services are: * Single sign-on across web sites * Profile exchange and form filling * Blog anti-spam Yadis provides the first step for any service that uses identifiers for authentication, accountability, privacy controlled data exchange and more.

URI::Query provides simple URI query string manipulation, allowing you to create and manipulate URI query strings from GET and POST requests in web applications. This is primarily useful for creating links where you wish to preserve some subset of the parameters to the current request, and potentially add or replace others. Given a query string this is doable with regexes, of course, but making sure you get the anchoring and escaping right is tedious and error-prone - this module is simpler.

The Net_UserAgent object does a number of tests on an HTTP user agent string. The results of these tests are available via methods of the object. This module is based upon the JavaScript browser detection code available at http://www.mozilla.org/docs/web-developer/sniffer/browser_type.html. This module had many influences from the lib/Browser.php code in version 1.3 of Horde.

This code was originally forked from Leah Culver and Andy Smith's oauth.py code (see net/py-oauth). A number of notable differences exist between this code and its forefathers: * 100% unit test coverage. * The DataStore object has been completely ripped out. * Classes are no longer prefixed with OAuth. * The Request class now extends from dict. * The library is likely no longer compatible with Python 2.3. * The Client class works and extends from httplib2.

hostapd is a user space daemon for access point and authentication servers. It implements IEEE 802.11 access point management, IEEE 802.1X/WPA/WPA2/EAP Authenticators, RADIUS client, EAP server, and RADIUS authentication server. The current version supports Linux (Host AP, madwifi, mac80211-based drivers) and FreeBSD (net80211). To use the ports version instead of the base, add: hostapd_program="/usr/local/sbin/hostapd" to /etc/rc.conf

Kamailio is an open source SIP proxy server that is capable of handling thousands of up calls in a second. Among the features it provides, are support for TCP, UDP and SCTP, secure communication via TLS for VoIP (voice, video), accounting, the most popular open source databases and much more. Originally starting out as the SIP Express Router (SER) project by the Fraunhofer Society in 2001, the design team got together in 2008, merged old and new source code and rebranded SER to Kamailio.
