I have a simple Sinatra server that I run through textmate but I can't access from another computer on the same network.
I'm running Ruby 1.9.3p327 and Sinatra 1.4.1 on a Mac OS 10.8.3. Firewall is disabled.
I tested the same scenario on different networks and computers.
The computer responds to simple pings but when I try to telnet port 4567 I can't establish a connection.

bind option to
You can do this from the command line using the built in server using the
$ ./my_sinatra_file.rb -o 0.0.0.0
