#16509 — Re: platform issues?

to run the tests, I sit at my dev machine and SSH to the server where I can copy & paste the test case directly into the python interpreter. If there's a typo, it's going to both of them equally.

I am concerned about the name lookup since our servers have had some network glitches in the past and I'm not confident in our DNS. We can browse the net on the server without a problem but to be sure, I tried this:

On the server:

>>> socket.gethostbyaddr(socket.gethostbyname('www.google.com'))
('yyz06s07-in-f20.1e100.net', [], ['74.125.226.84'])
>>> socket.gethostbyaddr(socket.gethostbyname('www.twitter.com'))
('www2.twitter.com', [], ['199.59.149.198'])

On the dev environment:

>>> socket.gethostbyaddr(socket.gethostbyname('www.google.com'))
('sea09s02-in-f16.1e100.net', [], ['173.194.33.48'])
>>> socket.gethostbyaddr(socket.gethostbyname('www.twitter.com'))
('www4.twitter.com', [], ['199.59.149.230'])


Since I'm actually trying to write a twitter client, I was more focused on the results from twitter. Since google and twitter are so huge and so distributed, I'd bet neither are good tests for this, but they look approximately right.

Are there better ways to test if our network setup is good? At least that would be a relatively easy thing to fix.

Adrian.

Is the server able to resolve www.google.com properly? If so, are you 
POSITIVE that the "url = " line on the server has no typos?

I think I'd first try "dig www.google.com" to be sure that it is 
resolving, then I believe I'd try to fetch the URL from your code sample 
using cUrl. If both of those work then I'm not sure what I'd look at next.
