Syntax
.-16384-------. >>-SECURE_PBSZ--+-------------+-------------------------------->< '-buffer-size-'
Parameters
- buffer_size
- The valid range is between 512 - 32 768. The default value is 16 384.
Usage notes
- The client initially issues the PBSZ command specifying buffer_size. If the PBSZ command is rejected, the client reissues the PBSZ command with a smaller value until it is accepted by the server.
- If the server receives a protection buffer size (PBSZ) larger than the value configured in the server's FTP.DATA configuration file, the server defaults to its configured value.
- The setting applies only to the Kerberos protocol.
