I'm in the process of converting my Bro installs from standalone instances to a Bro Cluster.
The previous standalone Bro instance/server I'm using for testing is not able to be updated by the manager when I list it as a worker node.
I have the following 3 machines:
manager - New Bro install. version 2.5-beta-79 (rhel7 python 2.7.5)
worker1 - New Bro install. version 2.5-beta-79 (rhel7 python 2.7.5)
worker2 - Previous standalone Bro instance. version 2.4 <---- Notice the version differs, does worker2 need to run the same version as the manager? (rhel6 python 2.6.6)
Everything works between manager and worker1.
Here is the output from broctl when worker2 is listed in node.cfg.
[BroControl] > check

Error: Failed to establish ssh connection to host <redacted IP for worker2>
ssh keys are working as intended. Even though the error says, "failed to establish ssh connection on host" I can see manager login on worker2 as the root user via ssh in secure log.
/bin/python is 2.6.6 and is in root's path. Everything in question is owned by root.
