ssh single port foward on multiple machines, possible?

in flag

I have to showcase a grafana dashboard to a group of familiar strangers. There is no VPN. Screencast is not interactive enough.

My idea is to set up a single linux user 'demo-user' and share the password for this user with the group. From there, everyone can create a port forward from their machine, to port 3000 on my machine.

The result would be +-50 machines running ssh -L 3000:grafana-server.example.com:3000 [email protected] to view the dashboard on their localhost:3000.

Apart from bandwidth issues, would this be possible? Are there better alternatives?

If you can expose ports, why don't you just publish the Grafana server directly?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
