    Hi
    I want to config MPD5 in such a way it uses external script for
    authentication in L2TP service, so I added these lines to mpd.conf
    Code:

    startup:
    set user admin 1234 admin
    set web self 127.0.0.1 5006
    set web open
    set console self 127.0.0.1 5005
    set console open

    default:
    load l2tp_server

    l2tp_server:
    set ippool add pool2 192.168.11.236 192.168.11.250
    create bundle template D
    set iface enable proxy-arp
    set iface enable on-demand
    set iface idle 1800
    set iface enable tcpmssfix
    set ipcp yes vjcomp
    set ipcp ranges 192.168.11.2/32 ippool pool2
    set ipcp dns 8.8.8.8
    set bundle enable compression
    set ccp yes mppc
    set mppc yes e40
    set mppc yes e128
    set mppc yes stateless
    create link template D-L l2tp
    set link action bundle D
    set link enable multilink
    set link yes acfcomp protocomp
    set link no pap chap
    set link enable chap
    set link keep-alive 0
    set link mtu 1460
    set l2tp self 0.0.0.0 1701
    set link enable incoming
    set auth disable internal
    set auth enable ext-auth
    set auth extauth-script /root/CODE/test/fu.sh

    According to this http://mpd.sourceforge.net/doc5/mpd31.html#extauth my
    script should work in this way:

    On invocation extauth/extacct scripts receive on stdin set of request
    attribute:value pairs terminated by empty line and must generate response
    in same format on stdout.
    Click to expand...

    So for test my fu.sh I just added to it these lines:
    Code:

    !/usr/local/bin/bash

    echo "AUTH_TYPE:"
    echo ""

    But in mpd.log file I got "undefine attribute "AUTH_TYPE" ". So I decided
    to test other attribute but always get same result as before [image: :(]

    Can anybody help me and say me how exactly I should use fu.sh?

    i found my mistake :D . AUTH_TYPE is request attribute not response :D . but now i have other problem . how use external script for authentication i mean with stdin i can get some attribute from MPD and i have users and their passwords in text file but i don't know how i should response to MPD and check a username and password is valid or not for login ?????????????????

    Have you read this: http://mpd.sourceforge.net/doc5/mpd31.html#31 ? It may be short, but informative. For detailed description of those attributes you may look into RADIUS RFC, since most of them were taken from there. For the beginning I recommend you to just save and analyze all arguments submitted to script.

      let's clear my situation : on my FreeBSD system i have a service that it using MPD . this service have its users and passwords . now i should add to this system an L2TP service and i want to use MPD too . but older service is using mpd.secret for authentication so i decided to use external script but can't do it . also for some reason i can't use RADIUS . i saw that link you mentioned but still i don't no how write that script ??????? can you give me another start point ( or example )?
      Is there another way so that this different service can work alongside together ( some solution that doesn't use RADIUS or external authentication ) ?
