Arun Shourie on Govt. defecit

Today was voting day in many states including Haryana (where I stay) and I just casted vote. This was 2nd time I voted and first time when I voted in a Lok Sabha election (last time being for local Municipal Election). 

Sometimes back I came across a very nice lecture by one of great Indian scholar, politician, author and lot more Mr Arun Shourie.  

 

Some key points of his lecture

  • Political situation has degraded significantly and during the time he gave this lecture. Four of politicians including Haryana’s Ex-CM were in jail for some really serious charges. 
  • We are not using rights of freedom for the re-construction of society. Media is one of key institutions which has degraded so much. 
  • We feel proud to say that we are largest democracy though real bitter truth is that most of that is a complete disarray
  • No party in current time believes in ideology, idea or ideals. It’s plainly politics to get in power. (I personally disagree to this though). 
  • We have got lot’s of media channels and that make us feel very proud of though most just work in same manner. The pattern as well as the news is almost same on each of them. Diversity & plurality is not there. 
  • There’s a very organized structure of paid media in form of “rate cards” where certain rates are provided in well defined pattern for giving better news coverage. 
  • Indian media is very much into giving excessive coverage to insignificant events while there’s almost no interest in critical issues like state of defence, our position w.r.t. China, our internal security etc. 
  • Indian media has gone so much into “manipulation mode” that they use a lot of “So you mean to say….” kind of statement to make things more exciting while loosing the actual value in discussion. 
  • There’s almost no coverage in mainstream Indian media on scientific developments. New which has potential to impact our life significantly is not given any importance at all. 
  • Elite Indian class considers India to be a “Knowledge Super Powereven though without knowledge, no read and opinion on everything. 🙂 
  • There’s too much of balanced journalism where idea is to show two sides and end every debate with yes & no kind of situation. There’s no analysis or use of mind – it’s all just like showing a balanced, unquestionable picture of everything. While in real life there’s only side, only one side is right and not two sides. 
  • (Best advise:) Do not waste time in watching TV when it’s showing useless crap news. Just turn it off and watch TED talk or Authors @ Google videos talk on YouTube. 🙂
  • There’s a false sense that Indian society has become intolerant. Truth is that it’s all about weak state control.
  • Lokpal likely won’t help and all we need is three key changes in judiciary – No adjournments at all, Preponderance of probability and punishment not just in form of fine but also a ban from public life. 
  • Sad truth is that over time India is becoming weaker and weaker due to extremely poor governance. India is moreover governed by bureaucracy and not really political leadership. 

 

Some personal thoughts… 

I really wish to read his books and infact meet him someday in person. There are lot of things to learn from his experience. As Disinvestment Minister he was one of key persons in VSNL (Videsh Sanchar Nigam Ltd) disinvestment during Vajpayee’s Govt. This was time when this precious telecommunications infrastructure got investments from Tata Group which later turned it into Tata Communication after merging assets of VSNL, Tyco Global Network and TeleGlobe. 

Let’s see how will be new govt. 🙂

Why NIXI AS24029 appears to be transit ASN?

And my post on 1st April. Don’t take it as April fool post 😉

 

Multiple times NIXI’s AS24029 has been reported as acting like transit ASN for multiple networks. I have analysed it in past and this is very much because of route leaks by few specific networks. I have explained difference in peering Vs transit routes and their handling previously on my blog.

In short: A network is supposed to re-announce it’s peering and transit routes only to customer and not to any other peer or upstream. Whenever NIXI’s ASN appears in global routing table, its always the case where one or more networks are re-announcing routes learnt via NIXI to their upstream transits. 

 

Looking at Hurricane Electric’s bgp.he.net for NIXI’s AS24029, we get:

 

 

Now according to this – many ASNs are peers of NIXI and visible to HE. The problem with HE’s data is that it doesn’t shows who is downstream and who is upstream (but is pretty fast!). Looking at stat.ripe.net data for AS24029, we get:

peers_of_AS24029

 

This is very interesting data as left side are the ones which are actually announcing these routes to their upstreams. Finding  upstream is tricky since these are filtered out at global level are don’t stay in the global routing table. It would be overall hard to find ones whose path count is low but for ones with large path count, we can likely see those routes in RIPE RIS collected data. 

Using bgpdump on RIPE RIS data, I get:

anurag@server7:~/test$

Here we get the culprit ASNs. 🙂

So why does this happens?

Mostly it happens due the way filters are controlled in routers. Most of networks open their filters with upstreams to announce their customer routes. Now if customer routes are received via NIXI, they are re-announced as well. So in many of these cases these networks have/had the origination ASN as customer. 

These are the prefixes which are causing this:

anurag@server7:~/test$ grep "24029" latest.txt |awk -F '|' '{print $6}'|sort -u
103.245.200.0/24
103.27.140.0/22
116.214.114.0/24
123.136.159.0/24
182.48.209.0/24
183.87.210.0/24
183.87.244.0/24
183.87.250.0/24
202.140.137.0/24
202.3.15.0/24
203.119.50.0/24
anurag@server7:~/test$

 

 So that’s all about NIXI route leaks. Wish NIXI becomes a International hub for traffic exchange between Europe/Middle East and East Asia and as per current policy it’s no where around promoting domestic traffic exchange let alone international one!
