Looks like there SSH is not able to connect as there is a permission denied for the public key |
|
|
that's why I included a sample of manually running the ssh command testbed uses to test host habitability ... |
|
|
So the problem really is with the usage of the hostname 'localhost' in the hostfile. This is because the localhost controller will create peers with HOSTNAME set to 127.0.0.1 and the peers only get the localhost addresses. Thus the overlay links to those peers fail. Using the actual hostname of the machine doesn't seem to solve this as on my machine the hostname 'nautophone' resolves to '127.0.1.1'. Again the same problem in this case as the peers only get the localhost addresses. The problem is solved when you use the actual IP address of your local machine. For example I was able run testbed profiler successfully with the following hostfile: totakura@localhost:22 totakura@131.159.20.91:22 team@saturn:22 team@fulcrum:22 The IP is of nautophone's. Note that the first localhost doesn't arise a problem as it doesn't start any peers. The other two hostnames are resolved locally to their respective IP addresses and hence present no problems. |
