1. Ensure that the OpenSSL software in installed in the system.
2. For the HP-UX 11i v2 operating system, the WU-FTPD 2.6.1 software bundle provides
the FTP product bundle and the SSL libraries as two independent products. So, ensure
that the ftp-ssl-ncf FTP TLS enhancement software is installed in the system. Run
the following command to ensure that the software is installed:
# swlist -l product | grep ftp-ssl-ncf
The following output is displayed if the software is installed in the system:
ftp-ssl-ncf B.11.23.01.001 ftp-ssl-ncf web release
For the HP-UX 11i v3 operating system, the WU-FTPD 2.6.1 software bundle provides
the FTP server and the SSL libraries as a single product. So no additional software
is required to be installed on the system.
3. Configure the OpenSSL certificates and keys before you start the FTP client.
NOTE: This step is optional and required only if you use Client Certificates for
authentication.
4. Load the SSL-related variables using either of the following methods:
• Using the Environment Variables
To load the FTP SSL-related environment variables, use the following command:
#export environment_variable_name=value
To unset the variable, run the following command:
#unset environment_variable_name
Following are the environment variables in FTP:
FTP_USESSL Specifies if the client enables TLS security
mechanism.
FTP_SSL_MODE Specifies the secure mode. If mode is set to
tls, the client sends the AUTH_TLS command
to the server. If mode is set to ssl, the client
sends the AUTH_SSL command to the sever.
If mode is set to secure, the client sends the
AUTH_TLS command. If this fails, the client
sends the AUTH_SSL command to the server.
FTP_SSL_VERIFY_MODE Specifies if the peer needs to be verified. If this
flag is set to 1, peer is verified. By default, the
verify flag is disabled.
FTP_SSL_DEBUG_MODE Specifies if the SSL features must be invoked
in debug mode. If the debug mode is set to 2,
extended logging is performed.
