 * Scanner defines a virtual scanner.  For each user being scanned, a scanner
 * will use a file descriptor (and subsequent connection) for each protocol.
 * Once connecting it will negotiate the proxy to connect to

 * Once connected, any data passed through the proxy will be checked to see if
 * target_string is contained within that data.  If it is the proxy is

 * target_string is matched, or if at least max_read bytes are read from the
