In this post I’ve collected some tips to harden the default OpenSSH configuration on an Ubuntu LTS server. SSH protocol is usually used to connect to a remote machine securely. There are a lot of configuration options which can be used to make a server more secure. Disabling some features can help too if they are not needed.

I wanted to create a simple script to quickly access my notes from the command line. fzf is a great and flexible tool which can be used to fuzzy search in the given input, like the file names in my notes directory. I already use it to search in the command line history and in vim to open files with fzf.vim. In this post I will walk you through how I built my note script using fzf.
