1. Download exec-wrapper at http://code.google.com/p/exec-wrapper/downloads/detail?name=exec-wrapper-1.0.1.tar.bz2 or  http://hkvms.com/~alfred/exec-wrapper.tar.xz

Then you need to tweak the Perl scripts a little to avaoid warnings. If you are using the suidperl program you should replace #!/usr/bin/perl with the suidperl program (i.e. #!/usr/bin/suidperl) and use -U tag to execute unsafe commands.

#!/usr/bin/perl -wU

system(“/sbin/iptables”, “-L”);

And finally, you need to set the suid bit and change permissions of commands such as poff, pon, squid and cp to allow the CGI script to be executed as root.

# chown root:root <command name>
# chmod ug+s <command name>
# chmod a+x <command name>
