How to connect to a SVC endpoint?

Question

Given a URL that ends with .svc and that is supposed to run a SOAP web service, how can I get some data from it?

I tried:

• to access it via a web browser
• to access it via the Python's library Zeep
• to access it via the Microsoft utilitary svcutil.exe

In all cases, I get a timeout error:

Failed to establish a new connection: [Errno 10060] A connection attempt failed because the connected party did not properly respond after a period of time.

Does it mean that the web service does not work, or that I do things the wrong way?

Answer 1

Importantly - there is a big distinction between "service not active" (and by that I mean no listener on port 80), and "port not open in firewall".

If the problem were simply that you didn't have a service listening on port 80, you would have gotten something like "connection reset" or "connection rejected" as an error.

Instead, you appear to have gotten a timeout, which implies that either the SYN from the client doesn't reach the server, or the SYN/ACK from the server doesn't reach the client. [ You could verify this by doing a packet capture for port 80 on both client and server ]

I would be tempted to check any firewall in front of the server to see that it's letting port 80 traffic through from your client.
