# swlist -l product | grep ftp-ssl-ncf
The following output is displayed if the software is installed in the system:

software is required to be installed on the system.

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.
