Hi All, I read some of the documents about this but could not figure out exactly how to do this : Intercept every packet sent to TCP layer by IP layer and logging them in user space. If somebody could answer following question that will be a great help. 1: Does netfilter framework allows to intercept packet at this level directly.?? 2: Registering a hook with NF_IP_LOCAL_IN is what i need to do ?? 3: Can logging task be handled by ulogd . My module will sent data to a user app which will be developed using ulogd ?? Any help or just a pointer to links where i can find this info would also be of gr8 help. Regards, TellMeMore
