linux firewall in c
- by asha
i m implementing a firewall for linux,i want to block packets using loadable kernal module(lkm).
please help me how can i do it ?
i just know that it can be done by lkm by using some function in it,like init(),clean_up.
i want to know how to use DROP,ACCEPT in blocking function within lkm.
i want to do it without iptable command.
