  • gitso – Gitso is to support others. – Google Project Hosting – Gitso is a frontend to reverse VNC connections. It is meant to be a simple two-step process that connects one person to another's screen. First, the support person offers to give support. Second, the person who needs help connects and has their screen remotely visible. Because Gitso is cross-platform (Linux, OS X and Windows) and uses a reverse VNC connection, it greatly simplifies the process of getting support.
  • Everything Sysadmin: a list of dumb things to check – When you are debugging a problem for hours and hours, you suddenly realize, "I bet it's something really dumb!" It often is. Therefore, we present… a list of dumb things to check

  • 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.

  • Debian Clusters – This site is a series of step-by-step tutorials for anyone interested in building a Debian cluster. It is geared particularly towards those interested in a Debian cluster for education or research purposes. This site is being written alongside the construction of a real Debian cluster at my institute, starting from the ground (basic networking, DHCP, DNS, authentication) up through installation a queue/scheduler and scientific software.

    However, these tutorials and guides take some assumptions about users for granted, including basic Linux and Debian knowledge (see the Basic Linux Skills page for clarification and pointers to resources). This is not meant as an introduction to Debian or on how to cluster in general – thankfully, there are plenty of helpful tutorials and guides already in existence on those topics. A basic understanding of Debian and cluster technology will aid in following the tutorials.

  • SSH: What and How | Nettuts+ – Many web developers use SSH (“Secure Shell”) on a daily basis to manage their servers, back up files, work remotely, and a myriad of other tasks. Today, I’ll explain what SSH is, do a brief history review, and, lastly, teach you how to set it up on your remote server or even your local network. Let’s get started!
