How to Install APF

[1] Download and Install APF <syntaxhighlight lang="bash"> cd /usr/src wget http://www.rfxnetworks.com/downloads/apf-current.tar.gz tar -xzf apf-current.tar.gz rm -f apf-current.tar.gz cd apf-* sh ./install.sh</syntaxhighlight>

[2] Open the APF configuration file in your favorite text editor.

/etc/apf/conf.apf

A few lines need to be edited, search your conf.apf file for the appropriate line and modify them to reflect the changes below:

<syntaxhighlight lang="bash"> DEVEL_MODE="0" </syntaxhighlight>

<syntaxhighlight lang="bash"> IG_TCP_CPORTS="20,21,22,25,53,80,110,143,443,465,587,993,995,1167,2082,2083,2086,2087,2095,2096,2719,3306,35000_36000,49152_49161" IG_UDP_CPORTS="21,53,465" </syntaxhighlight>

<syntaxhighlight lang="bash"> EGF="1" EG_TCP_CPORTS="20,21,22,25,37,43,53,80,113,443,465,873,2087,2089,2719,3306,20001" EG_UDP_CPORTS="21,53,465,873" </syntaxhighlight>

<syntaxhighlight lang="bash"> DLIST_PHP="1" </syntaxhighlight>

<syntaxhighlight lang="bash"> DLIST_DSHIELD="1" </syntaxhighlight>

<syntaxhighlight lang="bash"> DLIST_RESERVED="0" </syntaxhighlight>

[3] Make sure that passive ports are open and that the FTP server is configured to use passive ports: <syntaxhighlight lang="bash"> pico /etc/pure-ftpd.conf</syntaxhighlight>

Change the following line: <syntaxhighlight lang="bash">

1. PassivePortRange 30000 50000</syntaxhighlight>

to:

<syntaxhighlight lang="bash"> PassivePortRange 35000 36000</syntaxhighlight>

[4] Restart FTP <syntaxhighlight lang="bash"> service pure-ftpd restart</syntaxhighlight>

[5] Restart APF <syntaxhighlight lang="bash"> service apf restart</syntaxhighlight>
