In 1997 or 1998 I had to live-edit some typos in html pages. I'd say it was an #apache webserver living inside a #linux server, and I had to login via telnet session (ISDN). The editor I used was nano.

@Hypolite Petovan I have setup a local #Apache and added an entry to /etc/hosts to point to my local machine. Then in a /etc/apache2/sites-available/friendica.conf I setup a virtual host on that host name and even setup a self-signed SSL certificate so I can run #Friendica locally. To be able to receive mails locally, as I have #Linux running here, I had to a bit patch Friendica to disable a regex check on the entered email address. Now when I want to locally federate with e.g. #GNUSocial I just have to repeat above steps and I remember I was able to setup "remote" follow between these two local instances. For Windows users, there is #WinAMP around for a very long time, including #Mercury mail server so you could be able to repeat it even on Windows.
