Network: FTP server: ProFTPd and how to install it...
(last edit: 2001-03-08)
                   This document is about replacing the standard ftpd from the FreeBSD kernel with the 
fancier ProFTPd.

Ok, here we go:

* First install it from /usr/ports/ftp/proftpd
  If you want to use the UseHostsAllow directive you will need to make it using:
  make --with-modules=${MODULES}

* Next we'll want it to run from inetd, because this way it (easily) gets booted at
  systemboot. To do this edit your /etc/inetd.conf And alter it to look like this:

----------------------------------------------------------------------------
#ftp    stream  tcp     nowait  root    /usr/libexec/ftpd       ftpd -l
ftp     stream  tcp     nowait  root    /usr/local/libexec/proftpd      proftpd
----------------------------------------------------------------------------

  Because we're starting ProFTPd from inetd. Your ProFTPd (to be found in: /usr/local/etc)
  config file will need the extra line of:

----------------------------------------------------------------------------
ServerType                      inetd
----------------------------------------------------------------------------

* With this done ProFTPd will boot when your system is started. (If you've just installed 
  and want to start it without rebooting kill -HUP your inetd process.)

Footnote: Anonymous access is off by default (good thing(tm)) If you want it on edit your
          /usr/local/etc/proftd.conf

==============================================================================

The next part will cover adding ratio's for users.

* This is basically how the ratio's work. Just figure out what you'll need and put that 
  into your proftpd.conf:
----------------------------------------------------------------------------------
The ratio directives take four numbers: file ratio, initial file credit, byte ratio, 
and initial byte credit. Setting either ratio to 0 disables that check. 

The directives are HostRatio (matches FQDN, wildcards allowed), AnonRatio (matches 
password entered at login), UserRatio (accepts "*" for 'any user'), and GroupRatio. 

     Ratios on                                    # enable module
     UserRatio ftp 0 0 0 0
     HostRatio master.debian.org 0 0 0 0          # leech access (default)
     GroupRatio proftpd 100 10 5 100000           # 100:1 files, 10 file cred
     5:1 bytes, 100k byte cred
     AnonRatio billg@microsoft.com 1 0 1 0        # 1:1 ratio, no credits
     UserRatio * 5 5 5 50000                      # special default case
-----------------------------------------------------------------------------------

* To make it complete, here is my entire config file (/usr/local/etc/proftpd.conf)
