When upgrading a cluster to a version with white listing enabled by default, where there are other interacting environments, it can be useful to initially disable white listing as a means to audit what external components are trying to connect with it.
Can we document how to disabled white listing, e.g.:
And also document that when disabled, that each client that would be refused access if white listing were enabled, will cause logging like this to the DaServer.log e.g.:
00000017 Operator 2019-11-20 16:58:39.617 17056 17074 "WhiteListing is disabled, ignoring: Access denied! [client ip=192.168.9.12, role=DaliDiag] not whitelisted"
Operations can leave disabled for a period and collate logging like this, to get a picture of what legitimate or potentially suspicious clients are trying to connect.
