That yes answer buried deep on the next-to-last full line is the answer that I typed giving SSH the go-ahead to make the connection and remember the key for next time If SSH ever connects to a host and sees a different key, its reaction is quite severe: $ ssh asaphrhodesmillorg @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY! Someone could be eavesdropping on you right now (man-in-the-middle attack)! This message will be familiar to anyone who has ever had to re-build a server from scratch, and forgets to save the old SSH keys and lets new ones be generated by the re-install It can be painful to go around to all of your SSH clients and remove the offending old key so that they will quietly learn the new one upon reconnection.

The paramiko library has full support for all of the normal SSH tactics surrounding host keys But its default behavior is rather spare: it loads no host-key files by default, and will then, of course, raise an exception for the very first host to which you connect because it will not be able to verify its key! The exception that it raises is a bit un-informative; it is only by looking at the fact that it comes from inside the missing_host_key() function that I usually recognize what has caused the error: >>> import paramiko >>> client = paramikoSSHClient() >>> clientconnect('myexamplecom', username='test') Traceback (most recent call last): .. File "../paramiko/clientpy", line 85, in missing_host_key raise SSHException('Unknown server %s' % hostname) paramikoSSHException: Unknown server myexample.

Notice two interesting things about the namespace name: The company name is at the beginning of the namespace name Namespaces can contain periods Company name Period namespace MyCorpSuperLib { public class SquareWidget { public double SideLength = 0; public double Area { get { return SideLength * SideLength; } } } }.

addition to storing the key within the block, Popfly stores the key permanently for future use by Flickr blocks that you drag onto the design surface. API keys are centrally managed by Popfly. You can learn more about that at the end of this chapter.

com To behave like the normal SSH command, load both the system and the current user's known-host keys before making the connection: >>> clientload_system_host_keys() >>> clientload_host_keys('/home/brandon/ssh/known_hosts') >>> clientconnect('myexamplecom', username='test') The paramiko library also lets you choose how you handle unknown hosts Once you have a client object created, you can provide it with a decision-making class that is asked what to do if a host key is not recognized You can build these classes yourself by inheriting from the MissingHostKeyPolicy class: >>> class AllowAnythingPolicy(paramikoMissingHostKeyPolicy): .. def missing_host_key(self, client, hostname, key): .. return .. >>> clientset_missing_host_key_policy(AllowAnythingPolicy()) >>> clientconnect('myexamplecom', username='test') Note that, through the arguments to the missing_host_key() method, you receive several pieces of information on which to base your decision; you could, for example, allow connections to machines on your own server subnet without a host key, but disallow all others.
