Error messages indicating userauth_hostbased mismatch are posted.
The sshd userauth_hostbased mismatch messages are innocuous only if they appear for the client sending one of the following: localhost, localhost.localdomain, slot1, slot2, slot3, slot4, slot5, slot6, slot7, or slot8. The system might post warning messages from sshd similar to the following: userauth_hostbased mismatch: client sends slot1, but the system resolves 127.3.0.1 to 127.3.0.1.
VIPRION-based system or VIPRION-hosted vCMP guest. This also occurs on a single slot.
None.
The system no longer posts extraneous warning messages caused by SSH connections from peers on the 127.0.0.0/8 subnet.
