Allow webrick server to be accessed over wifi

rated 0 times [ 2] [ 0] / answers: 1 / hits: 1479 / 3 Years ago, wed, november 24, 2021, 3:05:27

I am trying to access a rails server running at 0.0.0.0:3000 on my computer from a tablet on the same wifi.

I can connect to regular webserver :80, but somehow can't get to the :3000.

I tried:

sudo ufw enable 3000

but that didn't help.

The correct command to open that port would be

$ sudo ufw allow 3000                                     # from all hosts

$ sudo ufw allow from 192.168.1.0/24 to any port 3000     # just to some subnet hosts

Also you can resort to gufw, which simplifies a lot the firewall management.
