Infor required to use the exec_program

[Shankar Ganesh C]

Hi ,

I am trying to use the mod exec command to pass the request list parameters
to an external program when there is a accounting request start is recived.

The below steps  i have followed.

1) in the Acct_users files below statement are given.

DEFAULT Acct-Status-Type == Start
        Exec-Program = "/usr/bin/exec-program-wait"

2) In the radiusd.conf file

exec exec-program-wait {
                 wait = yes
                program = "exec-program-wait %{WaterCove-Bearer-Type}"
                input_pairs = request
                output_pairs = reply

        }

3) in the instantiate section  called the below module

        instantiate {

        exec exec-program-wait

4) Ensured the script is available in /usr/bin/exec-program-wait

5) Below is the script definition

#  For 'acct_users':
#
DEFAULT Acct-Status-Type == Start
        Exec-Program="/home/shankarganesh/freeradius-1.1.2/scripts/exec-prog
ram-wait"
DEFAULT Acct-Status-Type == Stop
        Exec-Program="/home/shankarganesh/freeradius-1.1.2/scripts/exec-prog
ram-wait"

printenv > /tmp/exec-program-wait
echo "Reply-Message += \"Hello, %u\","
echo "Reply-Message += \"PATH=$PATH\","
echo Framed-IP-Address = 255.255.255.255
echo "The prameter list of $* "
WaterCove-Bearer-Type = WATERCOVE_BEARER_TYPE
exit 0

6) When i try to run the server  below error message is logged in the server
, which could not find the environment variables .
