OpenFlow, GRE and VxLan Pcaps, Amazon EC2 BOTO (Python API)

Here are pcaps from the little experiment we did.

OpenFlow Pcap – is OVS and is OVS Controller 
Download here


GRE Pcap - Download here

VxLan Pcap - Open file in wireshark and "Decode As -> VxLan"  Download here

I have Amazon EC2 running OwnCloud software over Ubuntu. Amazon provides a Python based API, BOTO, to control the EC2 instances. Here is the code snipped to fish some info about your instance.

<Code Begin>


import boto.ec2
import re
import sys

def main():
  conn = boto.ec2.connect_to_region("ec2_location", aws_access_key_id='your_aws_key', aws_secret_access_key='your_aws_secrete')
  if conn:
    print "Connected to --->", re.split(':', str(conn))[1]
    print "Connection failed"

  reservations = conn.get_all_instances()
  print reservations,'\n'
  for i in range(0, len(reservations)):
    instance = reservations[i].instances
    print "Instance Name --->", instance[0]
    for x in range(0, len(instance)):
      print "Instance Type --->", instance[x].instance_type
      print "Instance Placement --->", instance[x].placement
      print "Instance ID --->", instance[x].id
      print "Instance State --->", instance[x].state
      print "Instance Public IP Address --->", instance[x].ip_address
      print "Instance Hyervisor --->", instance[x].hypervisor
      print "\n"

if __name__ == '__main__':

<Code End>
