Coming back from the US

Image
Sitting here in my hotel room, I was in deep reverie of the days that have passed since I have come to the US. It seems like a long time, but if my memory serves me right, its actually less than 2 months. It seems like forever. Snapping out of it, I am happy that i am getting to go back home 3 weeks earlier than expected and originally planned. I am supposed to be flying on the 8th of the May and if all goes well, I will be in Bangalore at the midnight of the 9th. I am so happy that i am literally counting my days here. My emotions would probably be understood by some one who is serving a life time sentence and his days of getting out of the jail is closing in. Anyways, these days have been like a sentence to the “ Kaala Paani ” (For those who don’t know what it means, It was a jail on an island where inmates were sent and they had no way to return)  . But this also has been an experience to me, driving 320 miles in 2 days just around Atlanta, meeting new people and to see the US...

The Unified Theory in the Grand Scheme of things…

In the search of the “Fundamental” entity in the grand scheme of things that we form a small part of, I thought it would be interesting to know a theory that makes the most logical sense. There have been fights, talks and debates about whether or not God exists. People have been imprudent enough to challenge the existence of God and term that Science is every thing. I thought this theory might interest them as well. Before I go any further, let me make it clear that I love science and this is nothing against science. What I believe science is a candle (or any Light source) in the centre of a dark room. We don’t know how big the room is or how big the space is, all we see is till where the candle can throw light on. when we get a better light source, we are able to see some thing we never knew in the past, some times proving our old assumptions wrong. Science is nothing more than when we gain understanding of how some thing works, and not really create it. It always existed, but we ne...

Checkpoint FW SPLAT Cluster XL Troubleshooting (NGX Versions)

In this blog, let us see a Step by Step approach that you would take to troubleshoot a Cluster XL problem in Checkpoint. Normally, this problem comes of after a reboot or an Upgrade or as a result on some change in the underlying network. When troubleshooting the CPHA, the following commands are very helpful cphaprob state cphaprob list cphaprob –a if The status of the CPHA is shown by the first command. First thing that you need to do is verify basic connectivity between the firewall interfaces. Allow the cluster members to ping each other (if not already allowed by the policy) and ping away, you should be able to verify the basic connectivity in this way. If the connectivity exists, then find out which firewall has the problem, it will normally be the down firewall Number Unique Address Assigned Load State 1 (local) 10.0.0.1 100% Active 2 10.0.0.2 0% Down Here as you can see the second firewall is down, you need to first go ahead and just execute ‘cpstop’ and ‘cpstart’ commands on t...
