  Installing  postman in  Linux Postman is the most popular tool among developers and testers. Today we are going to see how we can install postman in Linux. (I am using CentOS here, commands may somewhat differ for other Linux flavors)   Download the postman zip file. https://www.postman.com/downloads/     Open up a terminal and navigate to Downloads directory.   $ cd Downloads/   Extract the downloaded zip               $ tar -xzf Postman-linux-x64-7.33.1.tar.gz   Create a apps directory under /opt.              $ sudo mkdir -p /opt/apps/   Move the extracted Postman folder to above /opt/apps/ directory              $ sudo mv Postman /opt/apps/   Create symlink to access the postman with command              $ sudo ln -s /opt/apps/Postman/Pos...

  Bridged vs NAT connections At some point, we might all have deployed virtual machines using different hypervisors, be it Virtual Box, VMWare Player, etc. on our computers.   After installing the VM, we are usually provided with two network connectivity options: NAT or Bridged connection type.   Today we are going to look into the difference between the two network connection types. Let understand it with a below network diagram: Network Address Translation (NAT): When a VM is connected with NAT connection and network traffic is going out, the NAT device/adapter translates the address of VM to that of the host machine before packets are forwarded to external network. External world is not aware of the actual Virtual Machine, it will interface with Host machine. This is particularly useful when limited set of IP addresses are available in an organization.   The reverse happens when packets are received for the VM from external network (or Internet). In this case NAT ...
