Hi, I'm a newbie on Linux IP network, there are some problems that confuse me a lot. I sincerely need you help. In Linux IP network, when a packet is going to be sent out. Would you please tell me which one of the following items is right for the packet (Let's suppose struct sock *sk; struct socket *skt): 1), The packet has a sock (i.e. sk!=NULL), but doesn't has a socket (i.e. skt=NULL) corresponding to the packet? 2), The packet has a socket (i.e. skt!=NULL), but doesn't has a sock (i.e. sk=NULL) corresponding to the packet? 3), The packet doesn't has the both (i.e. sk=NULL and skt=NULL)? And, If some of them are right, Would you please also give me some examples of them? Thank you very much. ===== Best Regards, Park Lee __________________________________ Do you Yahoo!?
