Constructor & Destructor Documentation

declare a server socket

PFTPServer::PFTPServer ( const PString readyString)
Parameters:
readyStringSign on string on connection ready.

Delete the server, cleaning up passive sockets.


Member Function Documentation

virtual BOOL PFTPServer::AuthoriseUser ( const PString user,
const PString password,
BOOL &  replied 
) [virtual]

Validate the user name and password for access. After three invalid attempts, the socket will close and FALSE is returned.

Default implementation returns TRUE for all strings.

Returns:
TRUE if user can access, otherwise FALSE
Parameters:
userUser name to authorise.
passwordPassword supplied for the user.
repliedIndication that a reply was sent to client.
virtual BOOL PFTPServer::CheckLoginRequired ( PINDEX  cmd) [virtual]

Check to see if the command requires the server to be logged in before it may be processed.

Returns:
TRUE if the command required the user to be logged in.
Parameters:
cmdCommand to check if log in required.
void PFTPServer::Construct ( ) [protected]

Reimplemented from PChannel.

virtual BOOL PFTPServer::DispatchCommand ( PINDEX  code,
const PString args 
) [virtual]

Dispatching to the appropriate virtual function. This is used when the socket is acting as a server.

Returns:
TRUE if more processing may be done, FALSE if the QUIT command was received or the OnUnknown()# function returns FALSE.
Parameters:
codeParsed command code.
argsArguments to command.
BOOL PFTPServer::GetAllowThirdPartyPort ( ) const [inline]

return the thirdPartyPort flag, allowing 3 host put and get.

References thirdPartyPort.
