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
