ftphosts(4)                      File Formats                      ftphosts(4)



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 capabilities are supported:

       allow username addrglob [addrglob...]

           Only allow users to login as username from host(s) that match addr-
           glob.



       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 spec-
       ifies 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 user-
       name 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   *


       10.0.0.* can be written as 10.0.0.0:255.255.255.0 or 10.0.0.0/24.
