Symptoms

An attempt to start the listener fails with the following error stack:

TNS-12546: TNS:permission denied
TNS-12560: TNS:proto adapter error
TNS-00516: Permission denied

A listener trace reveals the following message:

[22-AUG-2007 12:22:02:571] nttvlser: valid node check on incoming node <ip address here>

[22-AUG-2007 12:22:02:571] nttvlser: Denied Entry: <ip address here>

Changes

This is likely a new installation or the sqlnet.ora file on the server has recently been edited to include a setting for TCP.VALIDNODE_CHECKING=YES.
