HP-UX AAA Server A.07.01 Administrator's Guide

1. Check if the radiusd daemon is already running by entering the following
command:
# ps -ef |grep radiusd
If radiusd is running, the radiusd process must be displayed.
If the radiusd daemon is already running, you can stop and start the HP-UX
AAA Server from the Server Manager Administration utility or the command line.
For more information, see “Starting AAA Servers Using Server Manager” (page 64)
or “Starting AAA Servers From the Command Line” (page 67). You can also
continue with the HP-UX AAA Server instance that is already running.
2. Enter the following command to verify that the authentication and accounting
ports specified for the RADIUS service in /etc/services (entries for radius
and radacct respectively) are in the LISTEN state and used by the correct process.
For example:
# lsof -i :<authentication port>
The authentication port (default, 1812) and accounting port (default, 1813) must
be in the LISTEN state and used by the radius process.
NOTE: The lsof tool is an open source tool and is not available by default on
HP-UX operating systems.
3. If another process is using the authentication or accounting port, configure different
ports in the /etc/services file or from the Start Options in the Administration
screen of Server Manager
Troubleshooting an Unresponsive HP-UX AAA Server
To troubleshoot an unresponsive HP-UX AAA Server, first determine whether the
HP-UX AAA Server is receiving requests.
To determine whether the HP-UX AAA Server is receiving requests, perform the
following steps:
1. View the HP-UX AAA Server logfile using the Server Logfile screen as described
in “Using Server Manager to Retrieve Logfile Information” (page 129). The server
logfile messages are displayed.
2. If the message was received, check the logfile for error messages and compare
them to the errors listed in the following sections:
• “Troubleshooting Common Configuration Problems” (page 344): Lists errors
caused because of incorrect configuration on the HP-UX AAA Server or the
RADIUS client
• “Troubleshooting External Services” (page 346): Lists errors caused by
unresponsive or failed external services
