Scapy is a powerful interactive packet manipulation tool, packet generator, network scanner, network discovery tool, and packet sniffer. It provides classes to interactively create packets or sets of packets, manipulate them, send them over the wire, sniff other packets from the wire, match answers and replies, and more. Interaction is provided by the Python interpreter, so Python programming structures can be used (such as variables, loops, and functions). Report modules are possible and easy to make. It is intended to do about the same things as ttlscan, nmap, hping, queso, p0f, xprobe, arping, arp-sk/arpspoof, firewalk, irpas, tethereal, and tcpdump.

The Multi Router Traffic Grapher (MRTG) is a tool to monitor the traffic load on network-links. MRTG generates HTML pages containing GIF/PNG images which provide a live visual representation of this traffic.

Braa is a tool for making SNMP queries. It is able to query hundreds or thousands of hosts simultaneously, while being completely single-threaded. It does not need any SNMP libraries, as it is equipped with its own SNMP engine. However, it's good to have a complete SNMP package including "snmptranslate" installed somewhere, because for speed reasons, there is no ASN.1 parser in Braa, and all the SNMP OIDs need to be specified numerically.

SmokePing is a network latency monitor which works in a way that is similar to MRTG. It measures network latency to a configurable set of destinations on the network, and displays its findings in easy-to-read Web pages. SmokePing has special support for monitoring hosts with dynamic IP addresses. SmokePing uses RRDtool as its logging and graphing back-end, making the system very efficient. The presentation of the data on the Web is done through a CGI which creates graphs on demand.

Big Brother

Big Brother is a combination of monitoring methods. Unlike SNMP where information is just collected and devices polled, Big Brother is designed in such a way that each local system broadcasts its own information to a central location. Simultaneously, Big Brother also polls all networked systems from a central location. This creates a highly efficient and redundant method for proactive network monitoring.

The libstatgrab library provides an easy-to-use interface for accessing system statistics and information. Available statistics include CPU, Load, Memory, Swap, Disk I/O, and Network I/O. It was developed to work on Linux, FreeBSD, and Solaris. The package also includes two tools: saidar provides a curses-based interface for viewing live system statistics, and statgrab is a sysctl-like interface to the statistics.

Pacemaker is a dynamic rate-limiting script that watches network traffic and determines which machines are probably abusing your network. Pacemaker catches things like Windows worm scans, port scans, P2P network traffic, and anything else that tries to go beyond the normal number of connections a standard machine should use. The machine needs to abuse the network for two minutes before pacemaker will mark the IP address to be rate-limited. A machine will stay marked for as many minutes as it has abused the network.

WormScan is a utility written in Java for the purpose of reporting attempted attacks on your Apache Web server. It was written to be able to support an unlimited number of worms. It is, however, very extendable, and can easily be configured to search and report on just about anything that can be found in your Web server's log files. The reports themselves are customizable, and can easily be modified to suit your needs. Numerous configuration options let you tweak the performance and the output.

by Arsen G. Petrosyan
ICEWall Network Access System is a modular billing and security system. The main module is "IC-Radius" (a Radius protocol implementation); it is needed to work with VPN clients. It can set traffic limits and time limits, block viewing of external sites, etc. Th statistics module provides information about individual clients and total usage.
