Client programs that read, parse and process Argus data, and comprise the client part of the Audit Record Generation and Utilization System. Argus is a generic IP network transaction auditing tool that has been used by thousands of sites to perform a number of powerful network management tasks that are currently not possible using commercial network management tools. Argus runs as an application level daemon, promiscuously reading network datagrams from a specified interface, and generates network traffic audit records for the network activity that it encounters. It is the way that Argus categorizes and reports on network activity that makes this tool unique and powerful.

IOG is a network I/O byte grapher made to graph cumulative KB/MB/GB totals for hours/days and months. It is intended to be simple, fast (support thousands of hosts) and integrate well with MRTG. Data for each host is updated hourly and HTML graphs are created. It uses a data consolidation algorithm which allows for a small, non-growing database file for each host. No external graphing libs or executables are required. IOG has been used in several production ISP environments, including at the authors company, Dynamic Internet (dyni.net). -Larry Rosenman <ler@lerctr.org>

To ease the task of network administration, decrease the likelihood of erronous command execution and to maintain all network services from a central point, EnderUNIX SDT anounces the availability of its 9th open-source tool, netUstad. It has been coded in C language and includes its own HTTP server. The newly anounced version provides a web interface for system administrators to add/delete/update FreeBSD IPFW and Linux IpTables rulesets, manage routing table and network interfaces. You can manage your Firewall via a TCP/IP connected remote PC, easily. Project Page:

Net::IPAddr is a collection of helpful functions used to convert IP addresses to/from 32-bit integers, applying subnet masks to IP addresses, validating IP address strings, and splitting a FQDN into its host and domain parts. No rocket science here, but I have found these functions to very, very handy. For example, have you ever tried to sort a list of IP addresses only to find out that they don't sort the way you expected? Here is the solution! If you convert the IP addresses to 32-bit integer addresses, they will sort in correct order.

pmacct is a set of network tools to gather IP traffic informations (bytes counter and number of packets); aggregation of statistics is done using simple primitives (MAC addresses, source host, destination host, ports and ip protocols) that can be used alone or combined together to form complex aggregation methods; counters are either global or historical (broken at fixed timeslots). Data is either stored in a memory table, pulled to stdout or in a SQL database (MySQL or PostgreSQL). Gathering packets off the wire is done either using pcap library (and promiscuous mode of the listening interface) or reading Netflow packets coming from the network.

Slate: simple traffic analysis and data reporting collection server for LFAP This package contains a small Lightweight Flow Accounting (LFAP) server and LFAP API library. LFAP open solution to delivering accounting data from Riverstone Networks Switches and Routers. You can use the sfas program to obtain micro-flow information from a Riverstone switch running either in Layer 4 bridging mode, routing or MPLS LSPs. Data that can be collected includes everything from an IPv4 header and UDP headers and the src/dst port from a TCP header.

The transmission-daemon is a daemon-based Transmission session that can be controlled via RPC by transmission-remote (included) and other Transmission BiTtorrent client such as GTK+ and CLI interface. Transmission has been built from the ground up to be a lightweight, yet powerful BitTorrent client. Its simple, intuitive interface is designed to integrate tightly with whatever computing environment you choose to use. Transmission strikes a balance between providing useful functionality without feature bloat. Furthermore, it is free for anyone to use or modify.

bsdproxy is a generic, event-driven proxy designed specifically for the BSD platform. It uses the kqueue()/kevent() system calls to determine when to relay data from one side of the connection to the other. It also uses GLib (http://www.gtk.org) data structures and memory management functions to optimize steady-state performance (minimize unnecessary memory allocation/deallocation). bsdproxy has been used to proxy HTTP, HTTPS, telnet, and mysql without any problems. It should be able to serve as a transparent proxy for anything over a TCP/IP connection.

The guacamole-server package is a set of software which forms the basis of the Guacamole stack. It consists of guacd, libguac, and several protocol support libraries. guacd is the Guacamole proxy daemon used by the Guacamole web application and framework. As JavaScript cannot handle binary protocols (like VNC and remote desktop) efficiently, a new test-based protocol was developed which would contain a common superset of the operations needed for efficient remote desktop access, but would be easy for JavaScript programs to process. guacd is the proxy which translates between arbitrary protocols and the Guacamole protocol.

GeoIP is a C library that enables the user to find the country that any IP address or hostname originates from. It uses a file based database that is accurate as of March 2002. This database simply contains IP blocks as keys, and countries as values. This database should be more complete and accurate than using reverse DNS lookups. This module can be used to automatically select the geographically closest mirror, to analyze your web server logs to determine the countries of your visitors, for credit card fraud detection, and for software export controls. This port includes a helper script, geoipupdate.sh, to help you keep the library up-to-date.
