Client Tracing
~~~~~~~~~~~~~~
1) Set the environment variable TNS_ADMIN to the directory where the
tnsnames.ora and listener.ora files exist.
The default location is $ORACLE_HOME/network/admin. Set $TNS_ADMIN
to this if it is not set. This ENSURES you know which files you are
using.
2) Start the listener: lsnrctl
> set password <password>
> start
Note any errors. If you do not have a password set then ignore the
set password command.
3) If the listener started, start the database.
4) Create a file in $HOME called .sqlnet.ora and add the lines:
trace_level_client= 16
trace_file_client=client
trace_directory_client= /tmp (or similar)
trace_unique_client=true
5) Try to connect from SQL*Plus thus:
sqlplus username/password@alias
or
sqlplus username/password
substituting a suitable alias.
6) If you get an error we may need to see the client trace file
/tmp/client_<PID>.trc where <PID> is the process ID of the
client process (*1).
This will be quite large so it is best to FAX or EMAIL it.
*1 Note: On earlier versions of SQL*Net the filename may NOT have
the process ID appended to it.
Listener Tracing:
~~~~~~~~~~~~~~~~~
1) Edit your $TNS_ADMIN/listener.ora file and add the lines:
TRACE_LEVEL_LISTENER = 16
TRACE_DIRECTORY_LISTENER = /tmp
TRACE_FILE_LISTENER = "listener"
2) Stop and restart the listener:
lsnrctl stop
lsnrctl start
Output should go to /tmp/listener.trc

Answer 1

By default in 11g traces will go to the ADR which is a new feature.
To disable that feature add the following line to your sqlnet.ora
diag_adr_enabled =OFF
[oops] saw that this is over a month old this post - sorry about that!
