Hello All, I am couple of questions on whether iptables can used to achieve my requirement. Test Setup Two Fedora core 9 ( kernel 2.6.25.6-55) systems running Intel 2 core duo processor as iSCSI initiator/target connected via Gig Ethernet switch IP Tables v 1.4.0 Requirement On the target system, I have to look for packets that have TOS bits set and in those packets, I have look beyond the TCP header i.e. into iSCSI header for specific values. In this case, i am looking for iSCSI read command( first byte) and notedown ITT value ( 4 bytes, from 16-19 ) I studied manual pages and I am not sure whetehr IP tables/u32/ulog can help me to achieve me this requirement. Questions 1. I just need to pull out few bytes out from the packet and log it. 2. Whether ulog can record only few bytes or interested bytes in the paylod ?? Thanks in advance for your suggestions Regards Padmanabhan -- To unsubscribe from this list: send the line "unsubscribe netfilter" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
