  • Observium – Observium is an autodiscovering SNMP based network monitoring platform written in PHP which includes support for a wide range of network hardware and operating systems including Cisco, Windows, Linux, HP, Dell, FreeBSD, Juniper, Brocade, Netscaler, NetApp and many more. Observium has grown out of a lack of network monitoring platforms which are both simple to manage and pleasant to use. It is intended to provide a navigable interface to the health and performance of your network. Its design goals include collecting as much historical data about devices as possible, using as much auto-discovery as possible with little or no manual intervention, and having a very intuitive interface. Observium is not intended to replace an up/down alerting system like Icinga or Nagios, but rather to complement it with an easy to manage, intuitive representation of historical and current performance statistics, configuration visualisation and syslog capture.
  • nikratio / S3QL — Bitbucket – S3QL is a file system that stores all its data online using storage services like Google Storage, Amazon S3, or OpenStack. S3QL effectively provides a hard disk of dynamic, infinite capacity that can be accessed from any computer with internet access running Linux, FreeBSD or OS-X. S3QL is a standard conforming, full featured UNIX file system that is conceptually indistinguishable from any local file system. Furthermore, S3QL has additional features like compression, encryption, data de-duplication, immutable trees and snapshotting which make it especially suitable for online backup and archival. S3QL is designed to favor simplicity and elegance over performance and feature-creep. Care has been taken to make the source code as readable and serviceable as possible. Solid error detection and error handling have been included from the very first line, and S3QL comes with extensive automated test cases for all its components.
  • Secure encrypted backup using duplicity for Linux and Mac – I have been looking for a replacement alternative to Dropbox which I use on my Mac mainly for backups (I rarely use the sharing). The requirements were secure encrypted backup (where I control the keys) and “intelligence” so incremental backups could be performed i.e. not copying everything every time[...]
  • Duplicati – Duplicati is a free backup client that securely stores encrypted, incremental, compressed backups on cloud storage services and remote file servers. It works with Amazon S3, Windows Live SkyDrive, Google Drive (Google Docs), Rackspace Cloud Files or WebDAV, SSH, FTP (and many more).   Duplicati has built-in AES-256 encryption and backups can be signed using GNU Privacy Guard. A built-in scheduler makes sure that backups are always up-to-date. Last but not least, Duplicati provides various options and tweaks like filters, deletion rules, transfer and bandwidth options to run backups for specific purposes. Duplicati is licensed under LGPL and available for Windows and Linux (.NET 2.0+ or Mono required). The Duplicati project was inspired by duplicity. Duplicati and duplicity are similar but not compatible. Duplicati is available in English, Spanish, French, German, Danish, Portugese, Italian, and Chinese.
  • MindTerm SSH Client 3.1.2 Signed Java Applet – Java SSH Client MindTerm SSH is a fully functional SSH client written in Java. This page presents Mindterm in the form of an applet. Please wait for the applet to load, it will load automatically once the archive is downloaded, be patient.

  • http://www.wormnet.nl/cprules – 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 CheckPoint.pm. I hope to use this library for other projects involving Check Point FW-1 databases …

    The other library, Template.pm, 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 (sam@tregar.com).

    The supporting program CPUsers.pl 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.
