ssh id files with ha clusters

[GaardenZwerch]

Hi,

when building clusters, is it safe to use the same /conf/sshd files on all nodes?
I need to trigger commands via ssh on the active node and I get conflicts because of .known_hosts otherwise.
Is there another way of handling the situation that a given IP can present different keys to ssh?

Thanks,

Frank

Hi Frank,

Individual keys are normal for devices that have separate IP addresses. But since you are accessing the same CARP IP I presume you can safely copy the keys from one machine to the next manually.

We don't want to handle key merge / replacement in case it differs from user expectation and since keys were never included in config.xml it's hard to recover them if we automate it.


Cheers,
