NAME

       ftpservers - FTP Server virtual hosting configuration file

SYNOPSIS

       /etc/ftpd/ftpservers

DESCRIPTION

       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 associates the address of  each
       virtual host with the directory its configuration files are stored in. The virtual host configuration files must be named:

       ftpaccess	       Virtual host's access file

       ftpusers 	       Restricts the accounts that can use the virtual host

       ftpgroups	       Virtual hosts enhanced group access file

       ftphosts 	       Allow or deny usernames access to the virtual host

       ftpconversions	       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 directory. 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 configure virtual hosts. See ftpaddhost(1M).

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

       address	 directory-containing-configuration-files

       For example:

       10.196.145.10	/etc/ftpd/virtual-ftpd/10.196.145.10
       10.196.145.200	/etc/ftpd//virtual-ftpd/10.196.145.200
       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 connected 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 naming issues, for example:

       10.196.145.20	 /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.
