Challenge response from server was incorrect!

[bern]

Hello,

For some of my servers, when executing cfrun, I receive the following
message:

# cfrun lablin04
cfrun(0):         .......... [ Hailing lablin04 ] ..........

I thought it might have been related to the keys, so I recreated them
but that did not fix the problem.  For all my servers, the files
cfservd.conf, cfagent.conf and update.conf are all the same then I
would believe the problem is not on the client's side.

Does someone have an idea what is the problem?

Also, how come CFINPUTS is set to /var/cfengine/inputs/cf.resolv?  I
did not set it up in any files.


Thanks,
Bernard
