  • – CPRules.html contains the description of the main program, how to create the html output from the Check Point files and how to influence the output.

    The program uses two supporting libraries and one supporting program. The first is specifically developed for this program to read and manipulate the Check Point databases in memory, called I hope to use this library for other projects involving Check Point FW-1 databases …

    The other library,, is used for creating the html pages from a template, giving more freedom in designing the web pages. The author of this module is Sam Tregar (

    The supporting program is to convert the exported userfiles to a CheckPoint database format to be used by CPRules. CPUsers.html describes how it works.

  • How To Calculate Bandwidth Utilization Using SNMP  [IP Application Services] – Cisco Systems – This document describes how to calculate bandwidth use with Simple Network Management Protocol (SNMP).
  • Long range WiFi antenna from Illy coffee can | John Graham-Cumming – I have a stack of half finished projects that I'm trying to complete. Happily, the first one was finished late last night: a long range WiFi antenna made using an empty coffee can. Working from the ideas here I made an antenna from the following:

    1. An empty 250g Illy Espresso ground coffee can

    2. A Type N bulkhead socket and a Type N plug

    3. A piece of WiFi antenna extension cable with a reverse SMA connector on the end.

    4. A short piece of coat hanger for the active element of the antenna

  • Tony’s VMware Site – I have assembled a package which you can download which will allow you to have Sound, Network, and CD ROM in your Windows For Workgroups 3.11 Virtual Machine.  I also have found a copy of Netscape 4.0 which will work with Windows 3.11.
  • Michele’s blog » Temperature in your server room – At work we bought a couple of Ethernet Boxes from MessPC to keep an eye on our different server room and monitore temperature, humidity and the presence of smoke. These Ethernet boxes are quite neat: they have one network port (10 Mbps half/duplex only, beware) and four RJ-45 ports where you plug-in the sensors you need. We got sensors for temperature, humidity and a smoke alarm.
  • Nagios plugin debugging – This little perl-scripts captures STDOUT and STDERR of a nagios plugin. It writes the captured output to a temp. file. Then the output is returned to Nagios for further processing.

    This allows to track down some problems when using plugins within Nagios. You'll get some information if you have problems accessing files, can view the expanded command-line parameters of service checks, view the performance data returned in a text file, etc.

    It did help me several times – so feel free to try this out.
