Question
Cannot connect to a port over the internet (works from localhost)

I’m running something on port 9292:
david@theta:~$ lsof -ni tcp:9292
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
ruby 2406 david 13u IPv4 1579461398 0t0 TCP 127.0.0.1:9292 (LISTEN)
david@theta:~$ telnet localhost 9292
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
The problem is that from elsewhere I cannot react it:
david@eclipse:~$ telnet 188.226.243.223 9292
Trying 188.226.243.223...
telnet: connect to address 188.226.243.223: Connection refused
Port 80 works:
david@eclipse:~$ telnet 188.226.243.223 80
Trying 188.226.243.223...
Connected to 188.226.243.223.
Escape character is '^]'.
I’m not using any firewalls.
What else can I try?
Thank you, David

How can I make it listen to outside connections as well?
I’m using Faye:
but I haven’t changed anything … before it worked… not sure if there is a special option to bind it ‘globally’… are you sure that lsof says it can be used exclusivelly on localhost?
As you can see in your lsof output, it’s bound to 127.0.0.1.
