Create your own customized vagrant base box

 



Below are steps to modify the vagrant image and save it for future use

 1. Login to you vagrant machine. Here I am taking example of Ubuntu 16.04
vagrant ssh

 2. Remove APT cache
sudo apt-get clean

 For Centos you can use 
yum clean all

 3. Reduce the size of OS
sudo dd if=/dev/zero of=/EMPTY bs=1M
sudo rm -f /EMPTY

 4. Exit from the VM and create vagrant base box
vagrant package --output mynew.box
Note: You should run the command in same folder where Vagrantfile is located for customized VM

 5. Add the mynew.box to vagrant box repository
vagrant box add myubuntu16 mynew.box

 6. Verify if box is added
vagrant box list

 7. Now you can deploy your customized VM
vagrant init myubuntu16

Understanding TCP & UDP

 TCP (Transmission Control Protocol) is stateful. This means it maintains a connection state between the communicating parties throughout the communication session. Stateful Nature of TCP Connection Establishment : TCP requires a connection to be established between the sender and receiver before data transmission can begin. This is done through a process called the three-way handshake. Three-Way Handshake : This process involves the exchange of three messages (SYN, SYN-ACK, and ACK) to establish a reliable connection. Maintaining State : During the connection, TCP keeps track of various parameters to ensure reliable and ordered data delivery. Sequence Numbers : TCP assigns sequence numbers to each byte of data to ensure it is received in the correct order. Acknowledgements (ACKs) : The receiver sends acknowledgements for the received data packets. If an ACK is not received, the sender retransmits the data. Flow Control : TCP uses a window mechanism to control the rate of data tran...
