How to backup an off-line installation of Cisco WCS 6.0.196.0

Well let’s say you have an error that brings down all your WCS installation and you do not have a recent backup. What can you do? How can you recover the DB?

For this there is a simple answer but first let’s take a minute to analyze the WCS structure. It’s made from three primary components:

Cisco Wireless Control Station 6.0.196.0 does not start…

In the recent days I’ve had problems with our install of Cisco Wireless Control Station v6.0.196.0. After a system restart, the service did not start and no apparent reasons where given to the user.

Whenever I tried to start the WCS via the batch file the result was an error:

Java Virtual Machine Launcher: Could not find the main class: com.zerog.lax.LAX .

How to scan your website or any other site for malware/viruses

I was reading on Softpedia today that the number of infected websites almost doubled in the second quarter of 2010 (http://news.softpedia.com/news/Number-of-Infected-Websites-Almost-Doubled-During-the-Second-Quarter-156591.shtml).

So I was thinking about some methods on how someone can easily scan a web address and I have found some addresses that one can visit:

Microsoft launches a self computing guide

Yep! It finally strike them that it does not matter how safe you make a system (not that Windows is the safest system around – but it’s over Apple for example http://news.softpedia.com/news/Macs-Are-Probably-Easier-to-Hack-than-Windows-PCs-Notorious-Hacker-Says-155507.shtml ) the human that uses the system will finally have the final word!
