iptables -m u32 --u32 "16=0xE0000001"
iptables v1.3.7: Couldn't load match `u32':/usr/local/lib/iptables/libipt_u32.so: cannot open shared object file: No such file or directory
Try `iptables -h' or 'iptables --help' for more information.
Actually I am trying to match MAC address from inside a DHCP message with some value and
then want to perform an action based on the result. For that I want to use U32 to do
a deep packet lookup using U32 option.
Any pointers ?
