django get data response from specific ip - django

Question

I am working on an API integration. I am using django==1.10.5 and python34. The app involves sending request from my server to another server which is connected through a VPN.
password = "xxxxxxxxxxxxxxxxx"
spid = "xxxxxxxxxxxxxxxxx"
serviceid = "xxxxxxxxxxxxxxxxx"
sendershortcode = "xxxxxxxxxxxxxxxxx"
initiator = "xxxxxxxxxxxxxxxxx"
initiator_password = "xxxxxxxxxxxxxxxxx"
recieveridentifier = "xxxxxxxxxxxxxxxxx"

headers = {'content-type': 'Content-Type: text/xml; charset=utf-8'}

myresponse = json.dumps(respO)
This code works fine i am able to get a respose from the other server.
My question is the other server is sending some other data which am getting when i tcpdup response i.e. tcpdump -A -s 0 'src xxx.xxx.xxx.xxx and tcp port 80 and (((ip[2:2] - ((ip[0]&0xf)<<2)) - ((tcp[12]&0xf0)>>2)) != 0)'
From doing this am getting this content.

Can someone help how i can get this content on the django view?
tcpdump image

Answer 1

you can do a tcpdump inside your python code using subprocess:
from subprocess import check_output
out = check_output(['tcpdump','args'])
you get the response in out and then you can work with it. for example:
out = check_output(['tcpdump', 'ether[0] & 1 = 0 and ip[16] >= 224'])
and you need to be root also
