ftphosts

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 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   *

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