SSHClient.connect fails on Windows XP

[Andrew Wilkins]

I have just upgraded to Paramiko 1.7.5 (Ernest), and tested it on a Windows XP host. Attempting to call SSHClient.connect fails with the following exception:
   paramiko.SSHException: No suitable address family for titan

This bug appears to have been introduced with the new IPv6 support. Calling getaddrinfo may yield results with socktype=0, which are silently ignored by Paramiko. If you specify a hint of socket.SOCK_STREAM, the resulting socktype should be socket.SOCK_STREAM. i.e.
   socket.getaddrinfo(host, port, socket.AF_UNSPEC, socket.SOCK_STREAM)

Hi,

I had the same problem under Windows XP and i solved it with your guidance.
This is my patch for client.py.

$ diff -u client.py.old client.py

Thank you for the solution. It works for me.
Hope they add this change to the code.

I just ran into this myself, just wanted to confirm that Alexandre's patch fixed my problem as well. Windows XP, Python 2.5.4, Paramiko 1.7.5. Thanks!

Hi, I am having the same problem as well, and am also fairly new to python, so I must ask a stupid question. How to I apply that patch file to client.py in my paramiko library? Thanks

Hi, I too do not know where to apply the patch client.py in the paramiko library. Any information regarding teh same would help me. Thank you.

[yakaneli (jenglund)]

Hey, I just looked at the file client.py and then did the changes myself
manually...and then it worked great. It only makes a change to one line, I
was able to figure it out pretty easily.

"patch" is a unix command and I was using windows anyway

Hope this helps ...

Additional information:
I have the problem possibly because I am attempting to connect to a local loopback address, one of my test case setups.

Interactive to the python interpreter for this gives:

>>> socket.getaddrinfo('127.0.0.1',22)
[(2, 0, 0, '', ('127.0.0.1', 22))]

socktype = 0
proto = 0
