Hi, I am trying to add a simple rule to INPUT chain using iptc_append_entry but it fails.It says invalid argument. I also tried sending the same ipt_entry structure which was returned by the iptc_first_rule API.In this case iptc_append _entry doesn't return an error but iptables -L doesn't display the rule in the list also. If somebody knows about the cause and solution please help me. thanks Babula __________________________________ Do you Yahoo!? Yahoo!
