Updates

I have been attending a few interviews, and most notably the ones from Limespot LLC, yes, the guys behind LimeWire P2P client. Also from Cable and Wireless as a Tier2 tech. Well, I understood that for the past few years a lot of things has changed and a lot of new standards, applications etc came into the picture. I am getting a little rusty here feels like a mammoth in present time. So, for the past few days most of the time was spent on reading up on new technologies, and missed out parts of some industry standard applications etc.

Most notably the ones I came across are, like LVS, RedHat GFS, Bind Views and Dynamic DNS updates using ISC DHCPd. I am simply posting some links here so that you can understand where to go in case if you need help regarding this also as a future reference for me.

For a starter you can find ALL types of DNS records here. and a few additions here. I hope this will come in handy.
Here is the link to setting up a LVS cluster using CentOS or RHEL and you can find instructions for a redhat clustersuite based cluster here.
Information on setting up GFS (Global Filesystem) is available here and the process of integrating it with GNBD is here.
Information on the Views feature of Bind can be found here with easy examples.
Integrating ISC DHCPd and Bind for setting up a Dynami DNS update method could be found here. This link was especially useful because the man pages and other documents do not touch this area deeply.

So, I guess thats it for now.
Ciao!

Boycott Trend Micro

Join FSF and the ScriptumLibre.org Foundation in boycotting all products and services sold by Trend Micro.

The proprietary software company Trend Micro has filed a patent infringement lawsuit against Barracuda Networks. They claim that Barracuda is violating their patent by distributing the free software antivirus program ClamAV.

We should avoid using any proprietary software, but companies that use software patents for aggression are the lowest of the low.

Lawsuits like this are a threat to the entire IT community, and to free software programmers in particular. There is little that can be done to stop patent trolls from exploiting the patent and legal system for financial gain, until we put a stop to the patenting of software altogether. But there is an immediate opportunity to punish and deter trolls like Trend Micro.

Let all of Trend Micro's potential customers know that by doing business with Trend Micro, they are supporting this attack on all creators of software works, including the entire free software community, and that the strongest message they can send to Trend Micro is to publicly boycott all of their products and services.

NSA INFOSEC

The NSA Infosec dept., yes the guys behind SE Linux extensions, provides great guides to lock down your system. They have various guides available for most of the operating systems, routers etc etc.

This is a site I used to frequent a long time ago, and then somehow it got left out. Now, from what I see, they have added plenty of guides etc to the collections. All of these resources are free and for public domain use.

Here is the link to site. I hope you will make use of these documents.
