| <<< Previous | Chapter 11. Shared Memory SPAM Filtering with Cyclone and -fastfilter | Next >>> |
Upon starting the filter program, the server immediately writes three Key: Value pairs, separated by a carriage-return and a newline, to the filter program's STDIN file descriptor. These three key-value pairs include :
The server's API version (2.0)
The mode (FastFilter)
The shared-memory key which can be used to attach to its shared memory segment.
For Example:
The initial setup message might look like this:
Version = 2.0\r\n Mode = FastFilter\r\n Key = <number>\r\n |
where <number> is the value supplied to the server via the -fastfilter <number> command line parameter.
