TemplateFx v2.29

 June 4th, 2013Jun 4th, 2013      

I am pleased to announce the release of version 2.29 of TemplateFx – a dynamic templating tool enabling you to write configuration templates once and deploy multiple times. Download links and instructions can be found on the TemplateFx page.

The changes in this release are summarised below:

  • Sorted out the shortcut/accelerator keys to be consistent with the native OS.
  • Replaced the tacky looking red “X” on the output tabs with a “Close” button.
  • Hitting escape on a confirmation dialogue now assumes a “No” response.
  • Added a toggle for regular expression matches to “Find and Replace” to allow literal matches.
  • Added text descriptions to toolbar buttons to remove confusion.
  • Made the toolbar icons look ever so slightly less ugly on Mac OSX.
  • Increased the size of the toolbar buttons to 20×20 instead of 16×16.
  • Fixed an issue where the bottom panel in the “Output” tab is squashed inconsistently.
  • Fixed an issue which caused “Find” to use “Whole Document” context instead of “Selection”.
  • The “Group By” JComboxBox can now be shrunk even with long contents.
  • Added support for key accelerators on toolbar icons.
  • Added support for labelling output tabs.

Cisco IOS: IPv6 Accounting using Flexible Netflow

 September 8th, 2011Sep 8th, 2011        1

I am a big fan of IP Accounting as it enables me to keep long term-ish statistics on a per src/dst prefix basis. I am able to work out my weekly or monthly bandwidth usage and can see how much data each host on my network uses. I can see that I have used a total of 4.7GB in the last 5 days and the majority of that has been towards my Apple TV. A lot of people are probably thinking this is probably achieved better using a more scalable solution like NetFlow, but I like the ability to query this data on-box and not have to use a collector.

Understanding PS3 NAT Types

 September 6th, 2011Sep 6th, 2011        50

After spending a little time investigating online gaming on the PS3, there appears to be a lot of conflicting information with regards to what NAT is and how the PS3 classifies your NAT type. Everyone who plays online seems to spend a lot of their time (instead of actually playing games) trying to achieve a different NAT type, or thinking their NAT type is why they keep getting shot.

NAT or Network Address Translation is something which people generally can’t avoid and has become the norm in computer networking. For a device to be able to access content on the Internet they need a public IP address. There aren’t enough public IP addresses (until IPv6 is fully embraced, which is still a way off) to give every one of your devices a public address which mandates a form of translation.
