Disabling "Banner" assumes significance in case of Oracle RAC Install. The result of not temporarily removing the banner is that the dba will see errors that say, "User equivalence failed for user oracle".
• Log in (or sudo to) user oracle
• cd ~/.ssh
• Modify (or create) a file named “config” in this directory, to add the following line (case-sensitive, left-justified):
LogLevel QUIET
• Save and close the file.
• Test to ensure that oracle can ssh to all other RAC nodes in the cluster, without being presented with a banner.
What is displayed as Banner is stored under /usr/localcw/opt/tcpwrapper/banners/
