I would like to use linode as a development box.
Rails development server runs on port 3000.
What would be the steps required to open 3000 for remote access.
I tried using
1)Arno Iptables [http://library.linode.com/security/firewalls/arno-iptables-debian-5-lenny]
but i still couldnt access rails server using port 3000
Here are the details for the linode
gauravt@gauravtiwari5050:~$ uname -a
Linux gauravtiwari5050 3.0.4-linode38 #1 SMP Thu Sep 22 14:59:08 EDT 2011 i686 GNU/Linux
gauravt@gauravtiwari5050:~$ lsb_release -a
