DHCHAP Authentication and Configuration
Note: This section is applicable to the FC RHEL5.x driver only.
To activate FC-SP/Authentication between the adapter host port and fabric F_Port
using DHCHAP, modify the DHCHAP-associated driver properties in the driver
configuration file.
The LPFC driver for Linux version RHEL5.x supports MD5 and SHA-1 hash functions
and supports the following DH groups: Null, 1024, 1280, 1536, and 2048.
Enabling Authentication
Enabling authentication is a two-step process. To enable authentication:
1. Start the fcauthd daemon.
2. Set the lpfc_enable_auth module parameter to 1 (enabled).
fcauthd Daemon
The LPFC driver requires the fcauthd daemon to perform authentication tasks for it. To
enable authentication, you must have this daemon running. If you want to load the
LPFC driver with authentication enabled, the fcauthd daemon should be running
before the driver is loaded. The LPFC driver can start with authentication enabled if the
daemon is not running, but all ports are placed into an error state.
When the daemon is started, the LPFC driver should discover the daemon and reset the
adapter to enable the LPFC driver to perform authentication. To test if this daemon is
running, start the daemon, or stop the daemon, you must use the /etc/init.d/fcauthd
script.
The script syntax is /etc/init.d/fcauthd <parameter>.
fcauthd Daemon Parameters
The fcauthd daemon supports the following parameters:

start - To start the fcauthd daemon, pass the start command to the fcauthd
script. This command loads the daemon into memory, opens a netlink
connection for the driver, and reads the authentication configuration database
into memory for use by the LPFC driver.

stop - To stop the fcauthd daemon, pass the stop command to the fcauthd script.
This command takes down the netlink connection between the fcauthd daemon
and the LPFC driver, and stops the fcauthd daemon.

reload - The reload command reloads the authentication configuration database
into memory. This is done whenever the database is changed by another
application (such as the OneCommand Manager application) or by you. If the
database is changed, the new configuration information is not used until the
fcauthd daemon reloads the database.

status - This command displays the current status of the fcauthd daemon. The
status should be either running or stopped.
