I have installed askbot experimentally on Amazon EC2, both of which I'm new to. On EC2 there's a feature called "Elastic IP" that assigns static IP to its virtual machine instance. When I start running askbot by following command WITHOUT using Elastic IP (meaning I used the IP dynamically assigned by EC2 at that moment), I can access to my askbot via browser by using WAN IP.

sudo python runserver `hostname -i`:8008

However, when I turn on Elastic IP, I can't access via browser ("not found" on browser, and no record in the web server's log).

It looks like hostname command returns LAN IP on EC2. So I tried:

sudo python runserver %WAN_IP%:8008

where %WAN_IP% is the one assigned by Elastic IP. This fails to run askbot complaining "Error: That IP address can't be assigned-to."

I want to keep using Elastic IP (since it's too cumbersome every time to change IP accordingly). Any idea would be appreciated.

The last 4 lines of my looks like this:

Looks like you need to associate the "Elastic IP" with your instance, please take a look at the Amazon documentation.

Take a look at the section "associate IP address with a running instance".

@Evgeny thx. Once I manage to have time I'll try your suggestion and report.
