Most of the terminal emulators auto-detect when a URL appears onscreen and allow to conveniently open them (e.g. via Ctrl+click or Cmd+click, or the right click menu).
It was, however, not possible until now for arbitrary text to point to URLs, just as on webpages.
These instructions are for implementing HTTPS on a NFSN-hosted static site using a certificate from Let's Encrypt. The certificate is generated manually on a separate computer.
Start off by installing the letsencrypt client. This requires sudo privileges and will install a bunch of packages:
% curl -O https://dl.eff.org/certbot-auto
% chmod +x ./certbot-auto
% ./certbot-auto
Generate the certificate. This will require you to publish some challenge responses on NFSN. I find it easiest to use tmux with letsencrypt running in one window and an SSH session to NFSN in another:
| #!/bin/sh | |
| #set -x | |
| # Usage: shibb-cas-get.sh {username} {password} # If you have any errors try removing the redirects to get more information | |
| # The service to be called, and a url-encoded version (the url encoding isn't perfect, if you're encoding complex stuff you may wish to replace with a different method) | |
