3. Create the /etc/sasldb2 file as a link to the /var/opt/sendmail/sasldb2

directory. Ensure that the /etc/sasldb2 file is a symbolic link to the

/var/opt/sendmail/sasldb2 directory on all the nodes in a cluster.

4. Ensure that the value configured for the DefaultAuthInfo Sendmail

configuration file option is in the shared volume.

NOTE: For information on configuring STARTTLS and AUTH with Sendmail, see

HP ServiceGuard Setup as a Recipient Mailbox Storage

If the Sendmail server is a recipient mailbox server, consider the following points:

• Users are same across all the configured nodes.

• The .forward file for each user resides in a shared volume group

• The ~.forward file is a symbolic link to a file in the shared volume group.

Configuring FTP with HP ServiceGuard

This section discusses the HP ServiceGuard monitor and startup/stop scripts for FTP.

It also discusses how to integrate HP ServiceGuard with FTP.

The FTP HP ServiceGuard Monitor Script

An FTP application package contains the monitor and startup/stop scripts. The FTP

monitor script constantly checks for the availability of an FTP process. When the FTP

The monitor script checks if any FTP processes are running in the system and exits if

FTP processes are not running in the system. Alternatively, the script attempts to

retrieve the process ID (PID) of the FTP processes and exits if the script fails to fetch

the PID. The monitor script continues the monitor operation until the script detects
