What is /dev/random? In Unix-like operating systems, /dev/random, /dev/urandom and /dev/arandom are special files that serve as pseudorandom number generators. They allow access to environmental noise collected from device drivers and other sources.
Here is an example where we generate a password with 10 symbols
</dev/urandom tr -dc '12345!@#$%qwertQWERTasdfgASDFGzxcvbZXCVB' | head -c10; echo ""
You can edit the symbols and the length for the generated password. -c10 is the lenght.
Have you ever wondered what is the speed of your ssh connection. For example you are connected to a server in Dubai but you live in London and now you want to know what is the speed if you need to scp something. Well the solution to this problem is called PV.
PV is a terminal-based (command-line based) tool in Linux that allows the monitoring of data being sent through pipe. The full form of PV command is Pipe Viewer. PV helps the user by giving him a visual display of the following, Time Elapsed Completed Progress (percentage bar) Current data transfer speed (also referred to as throughput rate) Data Transferred ETA (Estimated Time) (Remaining time)
So how to install in debian or ubuntu?
apt install pv
And now how to check you ssh speed? (SSH SPEED TEST)
