I used to work as a senior technical support for BEA Weblogic and had all sorts of crazy situations to debug remotely. Including one time when I had to get a person to edit a config file in Vim (which they never used before), on Unix (which they never used before), with me guiding them by phone (no visuals).

This is the one I recorded that seems to fit into the current theme: https://www.outerthoughts.com/2004/10/perfect-multicast-stor... (tldr: multicasting on 237.0.0.1 is bad).

And if somebody really understands network and multicast, I would love to know whether I actually nailed the problem or just made it go away accidentally. I have no problems with being wrong, especially this much later :-)
