NAME

       pfc - active precompiled filters generator

SYNOPSIS

       pfc <expression> >/etc/ppp/your.active.filter

DESCRIPTION

       This manual page documents briefly the pfc command.

       pfc  is the Precompiled Filter Compiler - a tool to generate "active precompiled filters".  If your pppd supports this feature, you can use
       this utility to generate the filter files.  The Active Filter allows a connect on demand pppd to determine what is  'interesting'  traffic,
       and then initiate the PPP session.  The tool allows you to create the filters, in libpcap format, for use by pppd.  Common filters are used
       to ignore traffic (ie: ntp, various protocol keepalives, etc...) so PPP sessions are not initiated until 'real' traffic requires them.

       Note that the generated compiled filter expression is specific to point-to-point links, and differs from the format  generated  by  tcpdump
       -ddd.

       (specify precompiled-active-filter=/etc/ppp/your.active.filter in the ppp options file)

EXAMPLE

       /usr/bin/pfc ntp and ldap > /etc/ppp/your.active.filter
