Highly Available HP-UX Internet Services (May 2008)

• Upload Feature
For the upload feature to function properly, user and group IDs/names must
be same across all cluster nodes.
• User Authentication Mechanism
The configuration of different user authentication mechanisms, such as
Pluggable Authentication Module (PAM), Kerberos, LDAP, Secure Sockets
Layer (SSL), must be consistent across all cluster nodes.
• Virtual FTP Feature
If the Virtual FTP feature is enabled, complete the following steps:
a. To move the /etc/ftpd/ftpservers file to the shared volume, enter
the following command:
mv /etc/ftpd/ftpservers /var/opt/ftpd/
b. To create a symbolic link to the shared volume from the
/etc/ftpd/ftpservers file, enter the following command:
ln -s /var/opt/ftpd/ftpservers /etc/ftpd/ftpservers
Ensure that each path mentioned in the /etc/ftpd/ftpservers file is
accessible by all the cluster nodes.
• SSL Support with HP ServiceGuard
To enable SSL support with HP ServiceGuard, move X509 certificates to the
shared volume at /etc/ftpd/security.
• Consistent Greeting Message
Ensure that the hostname of all the cluster nodes is the same for consistent
greeting messages. Alternatively, start the FTP service using the -a
command-line option and specify the greeting directive in the
/etc/ftpd/ftpaccess file to greeting terse.
