Distributed jMeter through VPN and SSL

Thursday 2012-02-16

This week I created a jMeter test setup for distributed testing. I thought it would be straight forward but I ran into some interesting things you might want to know if you are considering distributed testing using jMeter.

In my case, I had to test an application which was inside our corporate network, while working from home through a VPN and a firewall. Normally that is no problem, but jMeter has this funny construction where the slave (jMeter server) wants to connect back to the master (jMeter gui). It took some fiddling with iptables, the jMeter configuration and ssh tunneling to get it to work. Here’s my setup:

Strange fix for SMB problems in Linux

Monday 2011-11-28

Linux Sucks.Last week, the upgrade to Ubuntu 11 severely broke all carefully selected menu colors, graphics settings and icon sets. I gave up the fight after a few hours of effortless restoration work and switched to Linux Mint 11.

While setting up my machine and restoring the links to the company Windows file servers I could not connect. The password window would re-appear without any feedback. The fix was even stranger than the problem.

Gmail save to diskWant to save a single email from gmail to disk, in a readable format for Outlook, Thunderbird or Apple Mail? Here’s how:

  1. Open your browser and log into your gmail account.
  2. Open the email you want to save.
  3. On the top-right, there is a little triangle next to the “Reply” button. Click that, and select “Show Original”.
  4. The original, raw email opens in a new window or tab.
  5. Right-click on this new window, and select “Save as…”.
  6. When saving the file, make sure the extension of the filename is “eml“. So for example “MyEmail.eml”.

All done. Now you dan open the file in Thunderbird, Outlook or whatever email viewer you have out there and see the original mail, in all it’s marked-up glory.


Add some magic to Eclipse

Saturday 2011-07-30

Templatus Expandum!The top feature of the eclipse IDE is the very impressive refactoring possibilities. It makes code feel like play-doh, allowing you to knead it in any shape way or form you think fits the current situation. A close second to that is the impressive templates and code assist. Yes, Java is verbose, but I think 80% of the characters which make up a Java program was never actually typed. All the readability without the labour, brought to you by eclipse’s powerful templates.

What many people don’t realize is that you can easily add to this magic by creating your own templates. One of the first templates I always add to the environment is the one which adds a private static final log4j logger. I thought it would be great example to share with you.
