I'm writing a script that is going to be run from a server at my University.
The purpose of the script is to check websites and record their HTTP status code and IP-Address. This works fine generally, but I am encountering a problem I have a hard time solving:
When run from my local machine outside the university network, everything works.
When I run the script from inside the network, one particular site is not resolved. For some reason the DNS server at my university can't do the lookup. I have no control over that machine, so I'm looking for a way around it.
Is it possible to change which DNS server the script uses, when written like below? If not, how should I go about this instead?
The relevant code:
import requests
import httplib
import socket
def getresponse(self,*args,**kwargs):
response = self._old_getresponse(*args,**kwargs)
if self.sock:
response.peer = self.sock.getpeername()
else:
response.peer = None
return response
httplib.HTTPConnection._old_getresponse = httplib.HTTPConnection.getresponse
httplib.HTTPConnection.getresponse = getresponse
def check_peer(resp):
orig_resp = resp.raw._original_response
if hasattr(orig_resp,'peer'):
return getattr(orig_resp,'peer')
r = requests.get("http://www.stackoverflow.com")
try:
ip = check_peer(r)
except TypeError:
ip = socket.gethostbyname_ex(site)
