hello, By adding iptable rule iptable -A OUTPUT -j LOG I am able to check log of each outgoing packets. But i want to know who is actually calling ipt_log_target function defined in ipt_LOG.c as static unsigned int ipt_log_target(struct sk_buff **pskb, unsigned int hooknum, const struct net_device *in, const struct net_device *out, const void *targinfo, void *userinfo) I want to know which file in source code has pointer to call ipt_log_target function? I want instance/copy of const struct net_device *out to my function in kernel to know that eth0 or eth1 is transmitting packet. Thanks in advance. regards, cranium __________________________________ Do you Yahoo!? Make Yahoo! your home page http://www.yahoo.com/r/hs
