[Fab-user] Problem running any command on an EC2 instance

[Ognen Duzlevski]

Hello,

I have a fabric script that provisions an instance with an elastic IP.

The succession of steps is:

public_ip = provision_instance()
with 
settings(host_string=public_ip,user='ubuntu',key_filename=ssh_key,reject_unknown_hosts=False,disable_known_hosts=True):
    run("ls -l")

First time I run the script I see that the machine is provisioned (via 
the AWS console) but the run("ls -l") step fails with a timeout exception.

If I then go back and comment out the first step (the 
provision_instance() step) and re-run the script, the command run("ls 
-l") runs just fine.
Also, when the script fails the first time I can ssh to the EC2 instance 
from the same terminal just fine.

The provision_instance() function does not finish until the status of 
the instance is "running" and both status checks (2/2) are OK so I know 
the instance is accessible via ssh.

What gives? :-)

Thanks!
