FTPDaemon()

Create new FTP server on the default FTP port 21.

FTPDaemon(int)

Create new FTP server on the specified port and initialize it.

addFTPDListener(FTPDListener)

Registers new FTPDListener that will receive notifications for every new connection and every new command on every connection.

addUser(String, String, String)

Add a user into default user directory.

createConnection(Socket)

Creates connection processing thread for the new incoming connection.

getPort()

Returns port where this server accepts connections

getServerName()

Return FTP user by its name in the default user directory.

getUserStrings()

For the simplified access to the default user directory (via JavaBean-style property).

Performes csh-slyle "home substitution": a leading string in form ~user is substituted by the home directory of user 'user'.

init()

Initialize this server if it was not already initialized.

main(String[])

main that can be used to start and test the server.

makeURLStub(String)

Return an URL stub for this server, for the username specified, for example "ftp://user

nextRandom()

notifyListeners(FTPDConnection, String)

Notifies all listeners that command is issued on a connection

produceObject(String, String)

Produce an object that is represented by the path 'path' for user 'user'.

removeFTPDListener(FTPDListener)

Removes FTPDListener.

removeUser(String)

Removes a user from the default user directory.

run()

Runs the server.

setAllowAnonymous(boolean)

Allow or disallow anonymous access to this server.

setPort(int)

Sets the port where this server shuold accept connections.

setUserStrings(String[])

Setter for the userStrings property.

start()

Start FTP server, initializing it if needed.

userHome(String, String, String)

Authenticate user.

 public FTPDaemon()

Create new FTP server on the default FTP port 21. Do not initialize it.

 public FTPDaemon(int _port) throws IOException

Create new FTP server on the specified port and initialize it.

 public long nextRandom()

 public void start()

Start FTP server, initializing it if needed.

 public synchronized void init() throws IOException

Initialize this server if it was not already initialized.

 public String makeURLStub(String user)

Return an URL stub for this server, for the username specified, for example "ftp://user@127.0.0.1:8881".

 protected FTPDUser getUserByName(String name)

Return FTP user by its name in the default user directory. Override this method if you want to hook up your own user directory.

 public void addUser(FTPDUser user)

Add a user into default user directory.

 public void addUser(String name,
                     String pass,
                     String home)

Add a user into default user directory.

 public void removeUser(String name)

Removes a user from the default user directory.

 public String getServerName()

Returns the name of the server which is used in the initial FTP reply. Override if you want customize this name. (hostname or hostname:port is used by default).

 public synchronized int getPort()

Returns port where this server accepts connections

 public synchronized void setPort(int p)

Sets the port where this server shuold accept connections. Server should be reinitialized for this setting to take effect.

 public ThreadGroup getFTPThreadGroup()

Returns the ThreadGroup for the connections to this server. (Every connection is processed in a separate thread.)

 protected FTPDConnection createConnection(Socket incoming) throws IOException

Creates connection processing thread for the new incoming connection. Default implementation returns new instance of FTPDConnection. You need to override this method if you have written your own extension of FTPDConnection and want to hook it up to the server.

 public void run()

Runs the server. Normally you do not call this directly, call start() instead.

 public void notifyListeners(FTPDConnection conn,
                             String command)

Notifies all listeners that command is issued on a connection

 public VirtualObject produceObject(String path,
                                    String user) throws FTPDException

Produce an object that is represented by the path 'path' for user 'user'. Default method does the following:

    return getUserByName( user ).produceObject( path, this );
  

You can override it to implement your own behaviour (or you can override getUserByName and FTPDUser.produceObject).

Throws: FTPDException

if object cannot be produced for the path given

 public boolean getAllowAnonymous()

Find out if this server allowes anonymous access.

 public synchronized void setAllowAnonymous(boolean allow)

Allow or disallow anonymous access to this server.

 public synchronized String userHome(String user,
                                     String password,
                                     String challenge)

Authenticate user. Return null if authentication failed or user's home path if it succeeded. User and password are received from the client, and challenge is generated before client is asked for the password. Challenge is sent to the client in the request for password and thus can be (potentially) used to encript user's password. It is unused by the default FTPDUser implementation.

 public synchronized String[] getUserStrings()

For the simplified access to the default user directory (via JavaBean-style property). Every user is represented as a String in the following format: "name;password;homeOnly;home;prefix". homeOnly should be true or false and it determines if this user should be grated access only to subdirectories of its own home directory. prefix is an "invisible" part of the path, prepended silently to every path this user wants to access.

 public synchronized void setUserStrings(String userList[])

Setter for the userStrings property. See getUserStrings for the description.

 public synchronized void addFTPDListener(FTPDListener log)

Registers new FTPDListener that will receive notifications for every new connection and every new command on every connection.

 public synchronized void removeFTPDListener(FTPDListener log)

Removes FTPDListener.

 public String homeSubstitution(String patt,
                                String cuser)

Performes csh-slyle "home substitution": a leading string in form ~user is substituted by the home directory of user 'user'. ~ alone is substituted by the home path of the current user.

 public static void main(String args[])
