How to enable SSH to your ESXi server

This is probably the most important tip. Alas, no screenshots as I've done this on an actual machine, although I could have, in theory, installed ESXi from ISO as a guest on top of another ESXi and then shared the screenshots. But you'll believe me. And there's also a link to a similar tutorial, with images and whatnot, further below.
ESXi has two virtual consoles (a typical Linux has seven), which you can access and toggle by using Alt + F1/2 combo. VC2 is the pseudo-GUI management console. VC1 is the sort of tailed server log. No command line, allegedly.
However, if you type unsupported in this window, you will get command line. This is the first step. Next, we need to enable SSH. This is done slightly differently from typical Linux boxes.
Open /etc/inetd.conf in a text editor (vi). Search for the ssh line and uncomment it. Save the file and exit. Now, you need to restart inetd to get it to reread its configuration and startup with SSH enabled.
To restart inetd, locate its process in the process table:

ps -a | grep inetd

After you locate the inetd process ID (PID), restart it:

kill -1

Note: This is an unsupported feature. Please consult with your IT support, vendor, whoever if you want to do this, as you may accidentally break warranty or similar. In general, since you are using a free and unsupported product, this should not be a problem.
