NAME
     ftphosts - FTP Server individual user host access file

SYNOPSIS
     /etc/ftpd/ftphosts


DESCRIPTION
     The ftphosts file  is  used  to  allow  or  deny  access  to
     accounts from specified hosts. The following access capabil-
     ities are supported:

     allow username addrglob [addrglob...]

         Only allow users to login as username from host(s)  that
         match addrglob.


     deny username addrglob [addrglob...]

         Do not allow users to login  as  username  from  host(s)
         that match addrglob.



     A username of * matches all users. A username  of  anonymous
     or ftp specifies the anonymous user.


     addrglob is a regular expression  that  is  matched  against
     hostnames  or IP addresses. addrglob may also be in the form
     address:netmask or address/CIDR, or be the name  of  a  file
     that  starts  with  a  slash  ('/')  and contains additional
     address globs. An exclamation mark (`!') placed  before  the
     addrglob negates the test.


     The first allow or deny entry  in  the  ftphosts  file  that
     matches  a username and host is used. If no entry exists for
     a username, then access is allowed.  Otherwise,  a  matching
     allow entry is required to permit access.

EXAMPLES
     You can use the following ftphosts file to  allow  anonymous
     access from any host except those on the class A network 10,
     with the exception  of  10.0.0.*  IP  addresses,  which  are
     allowed access:

       allow   ftp   10.0.0.*
       deny    ftp   10.*.*.*
       allow   ftp   *
