HI Guys,
I'm a Newbie to Linux Kernel Development. Need some Clarification in understanding Net-Filter Hooks.
Can I register only for the Necessary Packets [Ex: IPSEC etc...] from the Net-Filters?? AFAIK ; Net-Filter Module send the Packets to the Corresponding Module based on pre-defined HOOKS. Let us say; there are Many Packets reaching that Hooks; and if I am Interested only in some Packets from Net-Filter module; can I do that ???
something like: iptables [some rules] -j ULOG ? Check "man iptables" and see if that suits your need. FYI ULOG target uses netlink to deliver the packet to user space for further processing. -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com
