This happens when running a daemon on a HP Unix server with Oracle 805. It is a segment from the sqlnet.log file. Here is the profile I'm using: 

# standard profile
# @(#) Profile.raven  @(#)
#
# Oracle stuff gets added here

export ORACLE_SID=dcci

Any ideas?
Typically, this type of error occurs because the user that started the Listener does not have the appropriate file permissions to write information in specific directories on the server. Your problem is the ORA-12546 error, "TNS: permission denied". Also make sure that you listener is listening on the correct port and that no one else is using it.
