NAME - RADIUS authentication plugin for pppd(8)


       pppd [ options ] plugin


       The  RADIUS  plugin for pppd permits pppd to perform PAP, CHAP, MS-CHAP
       and MS-CHAPv2 authentication against a RADIUS  server  instead  of  the
       usual /etc/ppp/pap-secrets and /etc/ppp/chap-secrets files.

       The  RADIUS  plugin is built on a library called radiusclient which has
       its own configuration files  (usually  in  /etc/radiusclient),  consult
       those files for more information on configuring the RADIUS plugin


       The RADIUS plugin introduces one additional pppd option:

       radius-config-file filename
              The  file  filename  is  taken as the radiusclient configuration
              file.  If  this  option  is  not  used,  then  the  plugin  uses
              /etc/radiusclient/radiusclient.conf as the configuration file.

       avpair attribute=value
              Adds  an  Attribute-Value  pair  to  be  passed on to the RADIUS
              server on each request.

              Sets Radius NAS-Port attribute to number equal to interface name

              Sets Radius NAS-Port attribute value via libradiusclient library


       To use the plugin, simply supply the plugin option  to  pppd,
       and edit /etc/radiusclient/radiusclient.conf appropriately.  If you use
       the RADIUS plugin,  the  normal  pppd  authentication  schemes  (login,
       checking  the /etc/ppp/*-secrets files) are skipped.  The RADIUS server
       should assign an IP address to the peer  using  the  RADIUS  Framed-IP-
       Address attribute.
