I have two nearly identical devices. spur will connect via ssh with one, but not the other. How do I figure out why?
>>> shell1 = spur.SshShell('10.201.140.242', 'username', 'password', missing_host_key=spur.ssh.MissingHostKey.accept)
>>> results = shell1.run(['ls', '-a'])
>>> results.output
'.\n..\n.aptitude\n.bashrc\n.cache\n.config\n.profile\n'
>>> shell2 = spur.SshShell('10.201.129.56', 'username', 'password', missing_host_key=spur.ssh.MissingHostKey.accept)
>>> results = shell2.run(['ls', '-a'])

I'm confused by the error message. What does returning the ip, and two key objects supposed to mean? Is there helpful info here I'm supposed to glean from that?
Both devices will accept ssh connections from the command line, so that sets aside an obvious problem.
Both are running the same version of Ubuntu, with the same login credentials. Home directories are even the same (no .ssh dir). Even further, both of their sshd_config files are identical (so, also using the same version among other config options).
The problem doesn't seem to be in the ssh settings, but the error gives no indication of where the problem could be!
Any ideas?
Enabling logging doesn't add much.

It might be telling that the SSH reports connection. The failure occurs before/during authentication. But as I said above, the passwords are the same -- both connections even use the same copy-pasted pw, which works without error on a command line connection.
