Sraps: connection refused

Today we've tried to verify the ownership of a certain Snom phone via the Sraps XML-RPC. Suddenly we're getting a "Failed to connect to secure-provisioning.snom.com port 8083: Connection refused" error message on every request.


Strangely enough, I'm not getting this message on my laptop. It only happens on our server.


Is there some blacklist you are applying? 


Sincerely,


Sander

Hi Sander,


Apologies for the delay, I was off unexpectedly for the last weeks.


If the script works on your laptop, than it is probably not a password issue. It seems to me that your server is having a netowrk problem connecting to the SRAPS server: "socket.error: [Errno 111] Connection refused". Can it be that a firewall is blocking the connection? Can you maybe try to connect your laptop (the one that works) to the same switch port as the server and check the connection?


You could also try to get a PCAP trace (using tcpdump, or wireshark, for example) of the server and check the network packets.


Thanks

Catalina

Hi Sander,


Yesterday we did some maintenance work with the redirection server.

The system is back up and running but we have had some problems with the user accounts. Can you please manually try to login to the portal (https://sraps.snom.com) and if that fails try to reconfigure your password using the "Forgotten your password?" wizard?

Let me know if you still have problems.

Thanks
Catalina

Hi Catalina,


Thank you for your swift reply :).


I have already reset our credentials and can login with them in the portal. The strange thing is, requests from my laptop work perfectly. But the exact same request from our server gets denied every time. They use the exact same credentials and request configuration.

Could there be something else at play here?


Sincerely,

Sander

Maybe you can try our cli?

Hi Catalina,


Due to my vacation I was unable to respond for a few days. I have tried the Redirection CLI tool and I get the exact same problem.


When I execute the CLI via our server:

  

./sraps.py
Username: Verbonden
Password:
Traceback (most recent call last):
  File "./sraps.py", line 664, in <module>
    pwd_val = validate_password(username, password)
  File "./sraps.py", line 322, in validate_password
    s.network.echo("ping")
  File "/usr/lib64/python2.7/xmlrpclib.py", line 1233, in __call__
    return self.__send(self.__name, args)
  File "/usr/lib64/python2.7/xmlrpclib.py", line 1591, in __request
    verbose=self.__verbose
  File "/usr/lib64/python2.7/xmlrpclib.py", line 1273, in request
    return self.single_request(host, handler, request_body, verbose)
  File "/usr/lib64/python2.7/xmlrpclib.py", line 1301, in single_request
    self.send_content(h, request_body)
  File "./sraps.py", line 210, in send_content
    connection.endheaders()
  File "/usr/lib64/python2.7/httplib.py", line 1052, in endheaders
    self._send_output(message_body)
  File "/usr/lib64/python2.7/httplib.py", line 890, in _send_output
    self.send(msg)
  File "/usr/lib64/python2.7/httplib.py", line 852, in send
    self.connect()
  File "/usr/lib64/python2.7/httplib.py", line 1266, in connect
    HTTPConnection.connect(self)
  File "/usr/lib64/python2.7/httplib.py", line 833, in connect
    self.timeout, self.source_address)
  File "/usr/lib64/python2.7/socket.py", line 571, in create_connection
    raise err
socket.error: [Errno 111] Connection refused

 


And executed locally, on my laptop:

 

./sraps.py
Username: Verbonden
Password:
###############################################
  Snom Redirection Server Console Ver. 1.4.1
  (c) 2010-2018 snom technology AG
###############################################
Verbonden%>

 

Clearly there is something going on on a network level. I'm expecting some sort of blacklist/firewall. Could you please check if the IP-address 37.97.152.71 is in your firewall? That is the IP-address our server uses.

Thank you in advance.


Bump :)

Dear support,


Please respond and help, as we're still experiencing this issue.
