.SH DESCRIPTION
tac_plus listens on tcp port
.B
-49
+49
and provides Cisco systems routers and access servers with
authentication, authorisation and accounting services.
.LP
Specify the configuration file name. A configuration file is
.B
always required.
-.TP
+.TP
.B \-P
Just parse the configuration file, echoing it to standard output while
parsing, and then exit. Used for debugging configuration file syntax.
.B \-t
Log all informational, debugging or error messages to
.B
-/dev/console
+/dev/console
in addition to logging to syslogd. Useful for debugging.
.IP

-NOTE:
+NOTE:
messages at priority LOG_DEBUG are never logged to syslog, Use the
.B
-\-t, \-d or \-g
+\-t, \-d or \-g
flags to see all messages produced by tac_plus. These flags
should not be used in normal service.
.TP
.B \-p <port>
Use the specified port number instead of the default port
.B
-49
+49
for incoming tcp connections. Note that this changes the name of the
pid file created by the daemon, which will append the port number to
the file name if the port is not the default one.
.B \-d <level>
Switch on debugging and write debug output into
.B
-/var/log/tac_plus.log.
+/var/log/tac_plus.log.
See the definitions of debugging flags at the bottom of tac_plus.h for
available flags and their meanings. Most flags cause extra messages
