There is an old laptop with a broken display, no HDD. But with the ability to boot from USB.
There is a desire to make a router that would be distributed online.
Accordingly, it should raise PPPoE, NAT ing the whole thing, + HTB shaping.
Sometime ago I saw a ready-made distribution for such cases. But the day searches were not found.
Yes you can collect from zero to just what you need.
But it takes time.
And if you have already ready it is better to use them.
If anyone knows, tell me such ready-made distributions.
