Prevent non-root users from logging in

touch /etc/nologin
Also with optional message: echo "no login for you" > /etc/nologin (This doesn't affect your current X session - you're already logged in!)

  • Logs all users out except root. I changed the grep to use a regexp in case a user's username contained the word root.

  • This is something I wrote for myself, to use on a server that I manage where the users have cryptic usernames, and I'd like to tag them with clear text. I'll modify it in the future to parse /etc/password which is the database where this information is from (which is a better way to achieve this). Add the following line to your .bashrc to check it out: function fingr() { sudo printf "User Name [$1]:" && sudo printf "\n\n\n\n\n" | sudo chfn $1 | grep : ; } The idea to write something like that came after reading this post (I'm not affiliated): http://shinnok.com/rants/2013/09/18/alternative-to-the-finger-unix-command $ fingr root User Name [root]: Full Name [Mr. Root]: Room Number []: Work Phone [555-GOT-ROOT]: Home Phone [] Other [Root account]: Show Sample Output
