Hi all, I am anyalysing tcp sequence no.s on single pc by running TCP socket program on ethernet card with ip 192.168.1.200. For that i added debug messages in tcp_v4_rcv and also in tcp_transmit_skb to check what seq. no. are used by kenrel 2.4.24. What results i found by doing dmesg on console is that -----------OUTPUT INTERFACE FOR TCP PACKET CONNECT---------- TCP_CONNECT After push tcp header in tcp_transmit_skb th->seq=-745717026 After push tcp header in tcp_transmit_skb th->ack_seq=0 After pull tcp header in tcp_v4_rcv th->seq=-745717026 After pull tcp header in tcp_v4_rcv th->ack_seq=0 But that is happening once in 10 times. Why am i got above -ve seq.no. results? regards, linux.lover - : send the line "unsubscribe linux-net" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
