I have many nerdy friends who have been Linux users for ages. But most of them don’t know such a thing as Openwrt exists or have never bothered to give it a try. It’s a very fun piece of software to play with and can be extremely useful for routing traffic. Wondering why it isn’t more popular/widely used.
Years ago I derived a flash with vtun on it. It’s so old, now, but vtun still goes and connects. And since it’s not systemd, it’ll keep hammering at the connection until it succeeds.
So these old routers are still out there, and when a soho site is sick and we can’t get in we instruct someone to plug in the blue box and it calls out for help.
It’s so ghetto but, in places like the southern states where rural power outages can outlast generator time, it has cut down our time to recovery tremendously.
