Systura Where information becomes knowledge...

I recently ran into a customer asking about availability for a solution we were proposing for them.  They were asking all kinds of questions, like mean time before failure(MTBF), availability - especially in a clustered environment, etc.  So, I did a fair bit of research on the subject and came up with the following.

Which text editor do you use?  I have used many over the years and a lot of the decision depended upon the operating system that I was running the editor upon.  These days, I spend most of my time on Vista and have found that I am bouncing back and forth between two different editors; Notepad++ and JEdit.

I use tcpdump a lot in when I am trouble shooting a problem and recently I had to trouble shoot a problem on a vlan trunked interface.  So, I would normally do something like:

tcpdump -i eth1 host 10.1.1.1 and host 10.2.1.1

But, because the interface was trunked, I saw no traffic.  After doing a quick search on the Internet, I found that I needed to add the "vlan <vlan id>" to my filter, which became:

tcpdump -i eth1 vlan 801 and host 10.1.1.1 and host 10.2.1.1

I have known about Zimbra for several years.  I always thought it was an interesting mail platform, but because I use Exchange at the office, I have not had a reason to use Zimbra.  After Yahoo! bought Zimbra, work started on the Zimbra Desktop client.  Like the Zimbra platform, I thought it was interesting, but did not have a use for Zimbra Desktop.

How do you test your Internet connection speed?  I have several sites that I usually try and they are Speakeasy - Speed Test, Toast.Net, TestYourVoIP.com and Speedtest.net.  I like Speakeasy and Speedtest.net the best as they give you an upload and download measurement.  Speedtest.net has cooler graphics and does allow you to put a mini- tester on your site, try
