Yes. Atleast ths issue I was having is resolved.
RANCID is making changes to the config and does not save it.
It sets page console to '0' exits without saving.
2 problems:
- console settings do not have page limit
- Other user logs in and out of NS gets a config save confirmation
message; even though no change has been made
The modified 'nrancid' and 'nlogin' provided by Mike does not change
configs by setting soncole to page 0 hence no config save message
appear. RO user account can be used by RANCID to back up the config.

Are you confirming that this works reliably?
