The motivation is: ssh to remote computer without port forwading, dynamic DNS and so on, the only thing needed is that the remote is connected to the Internet.

1. On remote get tmate, put it in /usr/local/bin (apt version as of 18.04LTS is too old):

curl -L https://github.com/tmate-io/tmate/releases/download/2.4.0/tmate-2.4.0-static-linux-amd64.tar.xz|tar xJv
sudo mv tmate-2.4.0-static-linux-amd/tmate /usr/local/bin

2. Put public keys in ~/.ssh/authorized_keys
