[paramiko] How to use settimeout with from_transport

[James Bardin]

I've wondered how to do this myself, and I have a method that works, but 
maybe someone will let us know if there's a better way.

My program uses a large number of connections simultaneously, so to set 
a short timeout for everything I do the following:

from socket import setdefaulttimeout
setdefaulttimeout(2)

This setting propagates up and is used by the sockets created by paramiko.


If it makes a difference, I'm building my connection with:
client = SSHClient()
client.connect(...)
sftp = client.open_sftp()
