The general idea of these scripts is to check as many things as possible with SNMP: disks, memory, load, network interfaces, running processes, etc... The other idea is to select disks, interfaces, process using regular expressions: - it is possible to test more than one disk/int/process in one Nagios check (ex.: eth* instead of eth0,eth1,eth2,...) - you only have to provide a unique part of the name to select a disk/int/process (ex. : "C:" instead of "C:\ Label: Serial Number xxxxxxx" makes it easy to use on multiple Windows hosts). Most of these scripts can make performance outputs.

Icinga 2 is a network monitoring system and parallel development branch to Icinga 1. Written from scratch, it builds on the success of Icinga 1 and deals with shortcomings inherited from Nagios as a fork. Icinga 2 is: - Easy to install with soft link activation of functions and packages - Multithreaded and very fast: Capable of thousands of checks per second - Intuitive to configure, using new object-based, template-driven format - Easy to extend with native support for Livestatus and Graphite - Cluster-enabled for distributed monitoring out of the box

Riemann monitors low-latency, transient shared state for systems with many moving parts. Riemann aggregates events from your servers and applications with a powerful stream processing language. Send an email for every exception raised by your code. Track the latency distribution of your web app. See the top processes on any host, by memory and CPU. Combine statistics from every Riak node in your cluster and forward to Graphite. Send alerts when a key process fails to check in. Know how many users signed up right this second.

This is a plugin package for Nagios. Quoting from the snmp4nagios home page: SNMP4Nagios is a package of Nagios plugins which use SNMP to query hosts. While some of the plugins use standard MIBs, most are designed for vendor specific agents. Unlike other Nagios plugins, they are able to scan hosts for objects which can be monitored. They also can keep performance logs and draw plots of these using Tobias Oetiker's RRDTool. Currently devices by Brocade, Cisco, Compaq/HP and Network Appliance as well as computers running Microsoft Windows or Net-SNMP and uninterruptable power supplies are supported.

Tcpreplay is aimed at testing the performance of a Network Intrusion Detection System by replaying real background network traffic in which to hide attacks. Tcpreplay allows you to control the speed at which the traffic is replayed, and can replay arbitrary libpcap traces. Unlike programmatically-generated artificial traffic which doesn't exercise the application/protocol inspection that a NIDS performs, and doesn't reproduce the real-world anomalies that appear on production networks (asymmetric routes, traffic bursts/lulls, fragmentation, retransmissions, etc.), tcpreplay allows for exact replication of real traffic seen on real networks.

GNUnet is an anonymous, distributed, reputation-based network. A first service implemented on top of the networking layer allows censorship- resistant file-sharing. Our goal is to provide an infrastructure for secure networking. All communication in GNUnet is authenticated and encrypted. The reputation model makes attacks on the network harder. GNUnet does not rely on any centralized services. While our goals are similar to projects like Freenet, Gnutella, MojoNation and others, we hope to provide a superior combination of features for users that value security more than efficiency.

MAD-FLUTE is an implementation of FLUTE - File Delivery over Unidirectional Transport (IETF draft). FLUTE is a protocol for the unidirectional delivery of files over the Internet, which is particularly suited to multicast networks. FLUTE builds on Asyncronous Layered Coding (ALC), the base protocol designed for massively scalable multicast distribution (RFC 3450). ALC is a protocol instantiation of Layered Coding Transport building block (LCT) (RFC 3451). MAD-ALC is an implementation of the ALC/LCT protocols. The MAD/TUT project is going on at Tampere University of Technology (TUT).

The linux-decnet project is an effort to bring full DECnet support to Linux; however, they also separately offer the latd package, a collection of programs that speak Digital's old Local Area Terminal (LAT) protocol. These programs enable network clients to reach serial devices connected to old LAT-only terminal servers, such as the DECserver 200/MC. This is a redistribution of the linux-decnet project's software, with FreeBSD compatibility added. It is based very closely on the NetBSD port by Matt Fredette and has benefited from the wonderful assistance of Patrick Caulfield (the original author).

eXosip is a GPL library that extend the capability of the oSIP library. It aims to implement a simple high layer API to control the SIP for sessions establishments and common extensions. Once completed, this eXtended library should provide an API for call management, messaging and presence features. eXosip2 has support for: * registrations. (REGISTER) * call initiation and modification. (INVITE, re-INVITE) * other methods within calls (INFO, OPTIONS, UPDATE) * call transfer. (REFER) * reliability for provisional response. (PRACK) * sip event package. (SUBSCRIBE/NOTIFY) * event state publication. (PUBLISH) * instant messaging. (MESSAGE) eXosip2 does not contain: * RTP. * audio interface * sdp negotiation. This allow you to write any kind of SIP endpoint/gateway.

GNetwork is a networking wrapper written in pure C against the Glib/GObject object framework. The intention here is to provide a useful and easy-to-develop-against sockets wrapper for GNOME2 & GTK+ 2.0 programs which require TCP/IP connection capabilities. It can be used by programs which do not use GNOME or GTK+ anyways,however. It is NOT recommended or intended for high-load server situations, just user applications which need TCP/IP networking. Proxies are supported completely transparently, using the same settings as gnome-vfs. -- The libgnetwork README
