SECURE_PROXY_CIPHER_LIST option for NetBackup servers and clients

The SECURE_PROXY_CIPHER_LIST option configures the ciphers that NetBackup uses for OpenSSL to encrypt communication through the vnetd network daemon. The SECURE_PROXY_CIPHER_LIST option is a colon-separated list of permitted OpenSSL cipher strings. For the permitted cipher strings, requirements, and limitations, see the OpenSSL cipher documentation.

You can use this option to change the ciphers that NetBackup uses. If you configure this option, NetBackup writes a message about your configured cipher strings to the vnetd nbpxyhelper VxUL logs. The following is an example:

"Using user configured cipher list: cipher_string:cipher_string:...

Warning:

Be careful when you configure the SECURE_PROXY_CIPHER_LIST option. Permitted OpenSSL lower-level primitives may overlap with the ciphers that provide no authentication or no encryption. Hosts that do not have a cipher in common in their cipher lists cannot communicate with each other.
