[RADIATOR] Executing an external script from Radiator

[M P]

 Hello all, How am I able to read the value of the User-Password attribute and pass it to a variable from an (AuthBy) EXTERNAL BASH script? Also, how am I able to send back the result to the user either successful (Access-Accept) or failed (Access-Reject)? Below is a snippet of my Radiator configuration: - - - < s n i p > - - -<Realm DEFAULT>
    <AuthBy EXTERNAL>
        DecryptPassword
        Command /usr/local/sbin/testauth.sh
        Fork
        RejectEmptyPassword
    </AuthBy>        AcctLogFileName %L/accounting/detail-%Y%m%d.log
</Realm>- - - < s n i p > - - - Below is my BASH script: - - - < s n i p > - - -#!/bin/bashUSERNAME=$(grep -i User-Name | awk -F'61|@' '{print $2}')
PASSWORD=$(grep -i User-Password | awk -F'= ' '{print $2}')
HOST=192.168.1.101
HTTP_PORT=80
URL="http://$HOST/credentials.php?command=password_retrieve&phonenumber=$USERNAME"
RETVAL=0set -xfunction die()
{
    echo -e "$@" >> /var/log/messages
    exit 1
}if echo "" | telnet $HOST $HTTP_PORT 2>&1 | grep -i Connected ; then    if [ $PASSWORD == $(wget -c -O - $URL | cut -d\| -f 1) ] ; then
    #    Make an Access-Accept reply to the user.
    else
    #    Make an Access-Reject reply to the user.
    fielse
    die "ERROR: The $HOST is down or unreachable on $(date)."
fiexit ${RETVAL}- - - < s n i p > - - - Lastly, I am getting the below line in my radiusd.log file: Tue Jun 28 13:53:01 2011 476732: ERR: Bad attribute=value pair: Connected to 192.168.1.201. Please advice. Thank you in advance. Regards, MP From: antmtp at hotmail.com

Hello all,
 
Thank you for all who responded to my e-mail.
 
Now, I have a problem though. First, I am just going to write the script in BASH as I don't know Perl. Second, there is no database here to verify the User-Name and User-Password. Everytime there is an Access-Request that is received by the Radiator, it should execute the BASH script to (maybe) wget or curl with an input parameter of the User-Name from an HTTP or HTTPS URL and will receive the output with the User-Name and User-Password to verify and then reply back with an Access-Accept. If during the wget or curl from the URL and the output is other than what I expect (the User-Name and User-Password), then Radiator should respond with an Access-Reject.

Hello all,
 
How am I going to execute an external script when Radiator receives an Access-Request? This script will actually do an HTTP API request from an external HTTP server to get the userid then once the script have it on the same server as where the Radiator is running, Radiator will now respond an Access-Accept.
 
Please advice. Thank you in advance.
