Hi , Have some behaviour change with FREEBSD compared to LINUX .
1. When sending the Same TCP packet once again [ Retranmission of TCP packet ] Whether the Same Identification field [ IP packet]used or not . but when seeing that thru packet capture, Free BSD sending the differnt one [ increases sequentially IP Identification] 2.Retranmission Time is not increasing Linearly with Respect to BSD. not keeping more time interval . AS per RFC expecting Retransmission timeout should increase Linearly. Issue is not seen with Linux Setup 3. Active SYN open state in FREE BSD setup , Does not reach Syn-received State. When Sending syn packet to DUT but for that FreeBSD is not sending back SYN/ACK . Issue is with Free BSD Setup.Linux works fine, 4.When checking the State - TIME-WAIT Sending FIN and expecting the ACK ;Getting the ACK properly. Sending Data Segment and Expecting the RST signal not getting the RST ; Instead DUT is sending the Last TCP packet. Issue seen only in Free BSD. Same issue in FIN-WAIT2 & FIN-WAIT1 State also . Sending FIN and Expect the ACK : Getting the ACK Sending Data segment with Data : Expecting the RST signal from DUT ; but got Last transmitted TCP packet[ FIN -ACK] Any idea about the above scenario would be helpful Thanks, Saravanan. _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
