MUD tools using D-Bus

FTPD

This is a FTP daemon using pyftpdlib.

The corresponding MUD needs to provide two objects via D-BUS with the following interfaces:

de.unitopia.Authentification
- int password(string user, string password, string application)
  
  Check the given user and password. application will always be "ftp" in this case. Return a value > 0 for success.
de.unitopia.FTPAccess
- int check_permission(string wiz, string perm, string path)
  
  Check the permissions of user wiz for path. Permission is a single character.
  
  Read permissions:
  - "e" = change directory (CWD command)
  - "l" = list files (LIST, NLST, STAT, MLSD, MLST commands)
  - "r" = retrieve file from the server (RETR command)
  Write permissions:
  - "a" = append data to an existing file (AxPPE command)
  - "d" = delete file (DELE command)
  - "f" = rename file or directory from (RNFR command)
  - "t" = rename file or directory to (RNTO command)
  - "m" = create directory (MKD command)
  - "n" = delete directory (RMD command)

The FTP daemon will be configured in the main program. See ftpd-example.py for an example.

All tools are released under 2-clause BSD as given in COPYING.
