"Premature end of script headers" bugging me

im running apache on red hat 9 and im trying to run a few scripits through PHP but im getting errors

when i run the script from a browser i get a internal 500 error and the error log tells me that i have "Premature end of script headers"
i presume this is an error regrading the structure of my script so ill post it here


# change: this script read the ip address of the user accessing the web page and matches it with it's MAC address.

#This MAC address is then sent a script called add, which allows it onto the network

read ip_address


sudo arp > /root/lankfordu/apache/logs/users.txt

sudo awk '{if ($1 == "'"$ip_address"'") print $3}'

/root/lankfordu/apache/logs/users.txt | /root/lankfordu/apache/cgi-bin/add

sudo $IPTABLES -t nat -A POSTROUTING -s $ip_address -j MASQUERADE

when i run the scripts from the command line i get ": bad interpreter: No such file or directory"

so anyideas!!? hope i gave enough info and i have the default test-cgi working so i dont think its anything to do with my httpd.conf file

also what is the best way to call this script from php

at the moment i have echo "'$REMOTE_ADDR' | /root/lankfordu/apache/cgi-bin/change";

but i dont think that will work

bad interpreter msg tell that you are missing /bin/sh, which I doubt.
Perhaps is your file using the DOS CR/LF line ending vs unix LF, so the system is looking for /bin/sh^M ...
