connectivity

In the vast and complex world of network management, ensuring that devices can communicate with each other over a network is crucial. One of the simplest yet most powerful tools available for testing network connectivity is the ping command. Originating from the English word "ping," which mimics the sound of a sonar echo, this handy utility is used to check if a host is reachable. In this blog post, we’ll delve into how to utilize the ping command effectively across different Linux distributions, and guide you through the installation steps where necessary. Ping operates by sending Internet Control Message Protocol (ICMP) Echo Request messages to the target host and waits for a response.

SSH (Secure Shell) is a protocol extensively used for secure remote operations in a range of professional and personal environments. Sometimes, maintaining a persistent SSH connection is crucial, especially when connectivity issues like network instability or random disconnections occur. That’s where autossh comes in handy. Autossh is a simple program designed to start, monitor, and restart SSH sessions automatically when they crash or are inadvertently stopped. This functionality makes autossh particularly beneficial for maintaining persistent tunnels or keeping a session active indefinitely.
