Process to get PUC certificate

By
Having a Pollution Under Control certificate, more commonly known as the PUC certificate, is mandatory for all the vehicles in India as per the Motor Vehicles Act. In metro and tier 1 cities, it is very easy to get a PUC certificate.

I haven't seen petrol pumps doing PUC checks themselves, but they generally contract someone to offer PUC checks. Therefore, presence of a vehicle with a BIG PUC board sign is a common sight near petrol pumps. Although, you will often find that the owner of that vehicle is "missing" (gone AWOL :P) for large periods of time and the petrol pump employees would "proudly" say that "that guy" is not their employee :(. So let us understand the process of getting a PUC certificate.

First and foremost, always inquire about the charges and the validity. The cost should not exceed Rs. 100 (in 2019. Please convert to inflation adjusted charges for subsequent years.). Generally PUC checks are valid for six months and you will get a certificate which will mention the duration of validity. As the PUC certificate is mandatory and since the certificate generally has a validity of six months, a vehicle owner needs to perform PUC test twice every year.

Let's come to the actual testing process which is very simple. The PUC machine has a long pipe which is attached to the silencer of your car. The car must have its engine running. The machine measures the amount of Carbon Monoxide (CO) for about 30 seconds and displays whether the emissions are within the prescribed limits. If the emissions are within limits it displays "PASS". If they are not, I don't know :p. My car has always been within limits. This time my car's emissions had 0.3% of CO which was well within the limit of 0.5% for four wheeler cars.

Once the test is done, you pay the person and get the PUC certificate. Make sure the certificate, which is more like the size of an ID card contains the following things:
  1. Serial number
  2. Vehicle registration number as on the number plate.
  3. Date of test
  4. Validity
  5. Test results - Percentage of CO emissions
Then comes the most important thing. Immediately go to your google calendar and create a reminder for the date when your PUC certificate is going to expire. That way, you would not forget the next test. Now keep the certificate in your vehicle drawer along with your registration papers and insurance, lock the car, put on your seat belt and have a safe drive.

Using static IPs in Linux

By
It is often a requirement to assign static IP addresses to some important and permanent network interfaces. This is to avoid setting up a local DHCP server or relying on IP given by your network provider which may not be stable. This post shows steps to configure static IPs in Linux using Ubuntu 16.04 and Ubuntu 18.04 distros. We are considering two distros as network configuration has changed significantly in Ubuntu 18.04. There are two general steps to be followed: 1. Configure the network interface and assign a static IP. 2. Restart interface for the changes to take effect. Ubuntu 16.04  The current interfaces on the system are as follows: As can be seen, enp0s8 interface does not have any IP. Let's assign a static IP to it. In case you already have an interface with a DHCP assigned IP, you just need to change that IP and make it static. Edit the /etc/network/interfaces file and add the following code block. Prefer using the IP address range available for pri...

Local domain name resolution using /etc/hosts

By
The /etc/hosts file is a powerful mechanism for managing the information about hosts in the local network in the absence of a local DNS server. Setup We have 4 VMs in the local /24 network. The following are the details: vm-1-ubuntu-16-04 - 10.0.1.11 vm-2-ubuntu-16-04 - 10.0.1.12 vm-1-ubuntu-18-04 - 10.0.1.21 vm-2-ubuntu-18-04 - 10.0.1.22 The VMs are reachable via their IP address but not by their hostnames. This is problematic because we have to remember their IP addresses everytime we want to access these hosts. It is would be much simpler to remember and access the servers by their hostnames. For that we need some sort of mapping between the IP addresses and their corresponding host names. There are 3 common ways of achieving this mapping. Setup a DNS server which handles resolution for your local network. Use an existing DNS server of the local Internet Service Provider (ISP) or any other higher level ISP. Note that a public static IP address is required for this s...

Simple HTTP Server in Python

By
Have you ever come across a need to share a file over a local network to a number of machines? Have you ever felt the need to share output of a task in text files available at a web-endpoint? Often, there is a requirement to quickly setup a light-weight web-server for such requirements. Python provides the easiest way to setup a simple HTTP server for such use cases with a single command. Python comes pre-installed with Linux as many of the linux libraries use python in background. Therefore there is no extra overhead of installing python. With support for python2 getting stopped in April 2020, many of the newer versions of linux distros come with default python3. Therefore this post will focus on setting up an HTTP server using both python2 and python3. We will be using Ubuntu 16.04, however it will work for majority of the linux systems where python comes pre-installed. Preparation Steps to follow before starting the server: Make sure you are in the directory which you want ...
