Hai All, I am implementing SMTP packet filter.I have made one blacklist using "link list" containg the ip addreses of whose packets have to be blocked.This blacklist is done in kernel module(kernel space).I want to give an option to modify the linklist contents from the user(Command line inteerface).How can it be done? Plz. bail me out from this problem. Thanks in advance for reply, Regards, shahnawaz __________________________________ Do you Yahoo!? Yahoo!
