In this post we will see how ssh works?, what is SSH tunneling? what is important of ssh tunnels and how to setup the ssh tunnel. When SSH server is installed in machine then by default its allowed ssh tunneling. SSH Tunneling (Port Forwarding) Tunneling is the concept to encapsulate the network protocol to another protocol. here we put into SSH. so all network communication are encrypted. It also called Port Forwarding. because in ssh tunneling we are going to bind one local port. so what are the packet we are going to send that particular port, all packets are transparently encrypt and delivered to remote system. What is the need for SSH Tunneling?      SSH is enough to administrate the remote system. its not enough to access the all services which are available in remote system. let i describe in the following scenario, now lets consider the scenario, System (192.168.56.101) is my system its conne...

Recently I compiled the latest kernel by manually for just fun. so i logged my experience here. I show the step by step to the compilation process. I followed the this reference for compile the kernel. Why Need to compile the Kernel? Some time some software or modules expected that some kernel flags needed to set while compile (build) the kernel. This kind of scenario we need to rebuild the kernel with specified configuration flags are set. When new kernel is released,  compile the new kernel and install in our system. But this is not recommend way to install the system. so use our distribution(Ubuntu, red-hat release )  kernel update. Check your Linux kernel version         In Linux system use uname -r or cat /proc/version to find the current kernel version Linux Kernel Version here 2.6.35.22  is current system kernel version Step 1 : Download the latest ke...
