Skype Vs Gmail phone: Quick check on latency with IP-PSTN gateways

Anurag Bhatia
I usually find that Gmail phone performs lot better then Skype for calls to PSTN. Usually latency on Skype is high as compared to Gmail phone in India (in US it was almost no difference). I looked around today and here’s bit of test data I collected by calling couple of numbers from Skype & Gmail phone & monitored UDP traffic to collect information about destination servers which is very likely IP-PSTN gateway.

Script to keep track of IP address of machine

Anurag Bhatia
Just now realized that I have over few thousand files in “Latest IP” directory. This is result of poor workaround I created sometimes back to keep track of IP address. To fix it, I wrote a quick shell script and good enough - it works! :) Prime purpose of this script is to write latest IP address along with date/time stamp. Thus, one can simply call this script from cron job to keep track of IP address usage.

Messed up SPF record of mtsindia.in domain

Yesterday I called MTS Data Card support but their IVRS system was failing in giving me my balance details. Eventually I decided to email their support and glad to say support email was also easily available on their website. Today I saw acknowledgement mail in spam. No big deal but I usually dig around genuine mails which go in spam to find exact cause. In this case I found mail was sent to me from customercare.

Frustration, frustration and frustration - Story of State Colleges in India

Anurag Bhatia
Today was our Summer Project viva day and overall it went good for me. Although I was suppose to give viva on Sat, but that just didn’t happened as I was kicked out and insulted from my respective teachers for “not wearing formal clothes”. That’s very sad. I am not taking it personally but I am just pointing out the level of education and overall mentality in state college education system.

Poor DNS setup from Idea ISP

Anurag Bhatia
DNS Lesson time! Today, I was just looking into website - ideaisp.net This site is overall pretty interesting as it’s showing various upstream links of IDEA Cellular ISP backbone. Seems like they are just using Cable & Wireless for most of International bandwidth although IDEA ISP is not functional yet. Anyways, this post is not about their geeky upstream peers & routing tables but how bad one can setup DNS! :)
