Fabric Container - connect error

[pratik_patel]

Hi,

After creating a fabric container, when I try to connect to the container, it fails with authentication error.

FuseESB:karaf@root> fabric:container-listr-list

root*                          1.0       true    fabric, fabric-ensemble-0000-1, fuse-esb-full success

  camel-container-9090         1.0       true    camel-cluster-server-port-9090 success

FuseESB:karaf@root>

FuseESB:karaf@root> fabric:container-connect camel-container-camel-container-9090

Connected

Password authentication failed

Connected

Password authentication failed

What can be the problem?

Thanks,

Hi Pratik,

When you are creating a fabric, you are prompted to either create a user or import one from etc/users.properties. Those credentials will get cached into the session of the shell and fabric:container-connect will attempt to reuse those. This also applies when you connect later on to the container using ssh.

The expected behavior is to try the cached credentials first and upon failure to prompt you for username/password. The fact that you were not prompted for username password makes me think, that for some reason stale values have been stored in your session.

So, I'd say that this seems like a bug.

Can you please provide some more details with the step you used since you connected to the session (the commands entered since you started fabric or since you sshed into it)?

Hi Ioannis,

Thanks for the reply. Too me also, it looks like caching issue. Because when I tried to create containers with different names and different profiles, I did not face this problem.

Attached is the list of commands that had been executed before I ended up into this issue.

Regards,

Pratik

I think that in your cache its not just "stale credentials". I think that in your case there must be a forgotten instance/container running.

In any case, after the first authentication failure, you should be prompted for credentials.

I logged a jira about that: http://fusesource.com/issues/browse/FABRIC-357
