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
