|unsigned long flags|
This function replaces tfFtpdUserStart() and opens an FTP server socket and starts listening for incoming connections. tfNgFtpdUserStart() can be either blocking or non-blocking as specified by its blockingState parameter.
- Indicates which FTP file commands are supported by the file system. It is the result of OR'ing together the flags (described below) corresponding to the FTP commands supported by the file system.
- Maximum number of concurrent accepted incoming FTP connections allowed. If zero, then the FTP server will accept as many connections as there are available sockets.
- Maximum number of concurrent pending (before being accepted) incoming FTP connections allowed.
- Amount of time in seconds that a connection can sit idle before the server closes that connection. If set to zero, the default idle timeout value (300 seconds (5 minutes)) is used.
- One of the following:
- TM_BLOCKING_ON for blocking mode.
- TM_BLOCKING_OFF for non-blocking mode.
- You can OR one or more of the following flags:
- When the stack is compiled to support both IPv4 and IPv6, the user may restrict the FTP server to only using IPv4 by setting this flag.
- To prevent the FTP bounce attack, the FTP server (starting with release 188.8.131.52) will, by default, return an error when receiving an FTP port command whose IP address does not match the IP address on the control connection. To change the behavior of the FTP server, so that it behaves as in releases prior to release 184.108.40.206, i.e. allow a PORT command with an IP address different from the control connection peer IP address, set this flag

- One of the following:
- flags is something besides what is listed above.

- maxBackLog is either negative, null, or it exceeds the current number of available FTP connections (see note below).
- tfNgFtpdUserStart() has already been called.
