Hello, I am trying to use exec to check if a user in valid in a custom PHP script, what I would like is to get multiple attributes returned. I created a module as: ======================================================================= exec checkuser { wait = yes input_pairs = request output_pairs = reply program = "/etc/raddb/check-user.php -log -debug '%{User-Name}' '%{User-Password}'" shell_escape = yes } ======================================================================= and then activated it in the "authorize" section. The check-user.php script I would like to output the following: ======================================================================= <?php echo "Access-Accept = Accept"; // I used also commas.. same error echo "Mikrotik-Group = student"; echo "Mikrotik-Rate-Limit = 1564k/6400k"; So howevery I am echo-ing these I just get: "Exec format error" ======================================================================== [checkuser] expand: '%{User-Name}' -> 'AC:81:F3:63:7D:07' [checkuser] expand: '%{User-Password}' -> '' Exec-Program output: Exec-Program: FAILED to execute /etc/raddb/check-user.php: Exec format error Exec-Program-Wait: plaintext: Exec-Program: FAILED to execute /etc/raddb/check-user.php: Exec format error Exec-Program: returned: 1 ++[checkuser] returns reject ====================================================================== What is the correct way to return multiple attributes in PHP All help is appreciated, that you.
