PFTPServer::~PFTPServer ( )

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:

user User name to authorise.

password Password supplied for the user.

replied Indication 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:

cmd Command 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:

code Parsed command code.

args Arguments to command.

BOOL PFTPServer::GetAllowThirdPartyPort ( ) const [inline]

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

virtual PString PFTPServer::GetGoodbyeString ( const PString & user ) const [virtual]

return the string printed just before exiting

virtual PString PFTPServer::GetHelloString ( const PString & user ) const [virtual]

Get the string printed when a user logs in default value is a string giving the user name

virtual PString PFTPServer::GetSystemTypeString ( ) const [virtual]

return the string to be returned by the SYST command

virtual void PFTPServer::OnError ( PINDEX errorCode,

PINDEX cmdNum,

const char * msg

) [virtual]

Handle an error in command.

Returns:
TRUE if more processing may be done, FALSE if the ProcessCommand()# function is to return FALSE.

Parameters:

errorCode Error code to use

cmdNum Command that had the error.

msg Error message.
