How do I Change server to Listen on localhost:9292

ruby
server

#1

built chat feature with RoR utilizing ajax for real time component; testing it I don’t get error however I dont have real time. I can see that server is running /listening as per below:

Thin web server (v1.7.0 codename Dunder Mifflin)
Maximum connections set to 1024
Listening on 0.0.0.0:8080


I have the following on the another open tab command line to start the chat portion and I do see it listening on different servers. Command came from a course im doing however the course is using a local IDE. How would I set up C9 for this? thanks

Command: rackup private_pub.ru -s thin -E production
