Hello RudiC,

Well the file comes from your sed command:

Code:
sed -n '/^ *hardware ethernet/ {s///; h; d;}; /^ *fixed-address / {s///; G; s/[;\n]//g; s/ / -p tcp -m multiport --dports 110,143,25,465,585,993,995,80,443 -m mac --mac-source /; s/^/iptables -I FORWARD -s /; s/$/ -j ACCEPT/; p;}' /etc/dhcp/dhcpd.conf >> forward.sh

Then i flushed all the uneeded letters from the forward.sh file in order to get a file with these two rows (ip & MAC)

Thanks RudiC for your interest , appreciated :-)

LIBRARY

SYNOPSIS

     #include <sys/mac.h>

     int
     mac_is_present(const char *policyname);

DESCRIPTION

     The mac_is_present() function determines whether the currently-running kernel supports MAC for a given policy or not.  If policyname is

     checked.

RETURN VALUES

     If the system supports the given MAC policy, the value 1 is returned.  If the specified MAC policy is not supported, the value 0 is returned.
     If an error occurs, the value -1 is returned.

ERRORS

     [EINVAL]		The value of policyname is not valid.

     [ENOMEM]		Insufficient memory was available to allocate internal storage.
