My ambition was to implement a small (better tiny) appliance for monitoring network health and network resources, short and longtime trends, running under VMware Server or VMware ESX. So I had an eye upon all components which are implemented on the system, to be as leightweight as possible. This was also the reason why no SQL DBMS based software was used.. The appliance is based on Ubuntu Jeos LTS (8.04.3 at the time of this writing). Almost all used components are from the related repositories. This tutorial shows how the appliance was implemented. I do not issue any guarantee that this will work for you! Used components: Ubuntu 8.04.3 JeOS as OS Nagios 2.11 for monitoring and alarming Smokeping 2.3 to observe latencies and paketloss MRTG 2.14.7 to observe networktraffic's tendencies RRDTool 1.2.19 as Round-Robin Database for storing all measurement data Lighttpd 1.4.19 as fast, lightweight webserver frontend weathermap4rrd for illustrating the networkweather ssmtp as extremely lightweight MTA for maildelivery The link for this article located at HOWTO Forge is no longer available. .

A lightweight (distributed?) network security monitor for TCP/IP+Ethernet LANs. It will capture certain network events and record them in a relational database. The recorded data will be available for analysis through a CGI based interface. . . .. A lightweight (distributed?) network security monitor for TCP/IP+Ethernet LANs.

Well, I've said "It will...", "It won't..."... but it all is already coded and working, I'm currently testing it on a campus network (UIB) with 3000+ thingies connected, some GigaBit Ethernet backbones, etc. Believe me, it works and it's optimized ;-D I just want to share it! It's not finished, because I want to add some features such as portscan detection, spam filtering, script-kiddie detection, etc. And I'd like to improve the web interface to make it more user-friendly, allow 'monitord' configuration changes, etc. And it could be easily modified to be distributed: I could have several 'monitord' running in different places of a medium/big network and recording information in a central (or distributed) database... this could help detecting MAC address spoofing...
