     ftpservers - FTP Server virtual hosting configuration file


     The ftpservers file is used to  configure  complete  virtual
     hosting.  In  contrast  to limited virtual hosting, complete
     virtual hosting allows separate configuration  files  to  be
     specified for each virtual host.

     The set of configuration files for  each  virtual  host  are
     placed  in  their own directory. The ftpservers file associ-
     ates the address of each virtual host with the directory its
     configuration  files  are stored in. The virtual host confi-
     guration files must be named:

           Virtual host's access file

           Restricts the accounts that can use the virtual host

           Virtual hosts enhanced group access file

           Allow or deny usernames access to the virtual host

           Customize conversions available from the virtual host

     You do not need to put  every  file  in  each  virtual  host
     directory. If you want a virtual host to use the master copy
     of a file, then do not include it in the virtual host direc-
     tory.  If the file is not included, the master copy from the
     /etc/ftpd directory will be used.

     The file names must match exactly. If you  misspell  any  of
     them  or  name  them  differently,  the server will not find
     them, and the server will use the master copy instead.

     The ftpaddhost utility is an administrative tool to  config-
     ure virtual hosts. See ftpaddhost(1M).

  File Format
     There are two fields to each entry in the ftpservers file:

     For example:    /etc/ftpd/virtual-ftpd/   /etc/ftpd//virtual-ftpd/
     some.domain      INTERNAL

     When an FTP client connects to the FTP  Server,  in.ftpd(1M)
     tries  to  match the IP address to which the FTP client con-
     nected with one found in the ftpservers file.

     The address can be an IPv4 or IPv6 address, or a hostname.

     If a match is found, The FTP server uses  any  configuration
     files found in the associated directory.

     If a match is not found,  or an invalid  directory  path  is
     encountered,   the  default paths to the configuration files
     are used. The use of INTERNAL in the example above fails the
     check for a specific directory, and the master configuration
     files will be used.

     Either the actual IP address or a specific hostname  can  be
     used  to  specify  the virtual host. It is better to specify
     the actual IP of the virtual host, as it  reduces  the  need
     for a domain lookup and eliminates DNS security related nam-
     ing issues, for example:     /etc/ftpd/config/faqs.org/
     ftp.some.domain   /etc/ftpd/config/faqs.org/

     Lines that begin with a # sign are treated as comment  lines
     and are ignored.
