Hi,Tüxen I will provide more detail: The Topology is: --------1(192.168.1.20) computer A ---------------------------1 computer B(192.168.1.80) --------2(192.168.1.50) means computer has two wireless cards , I name them with A_1 and A_2, computer B has one wireless cards, and its name is B_1.
Now, A_1 init a association with B_1. Here, I provide message getting from wireshark , INIT： Internet Protocol, Src: 192.168.1.20 (192.168.1.20), Dst: 192.168.1.80 (192.168.1.80) Supported Extensions parameter (Supported types: ASCONF, ASCONF_ACK, FORWARD_TSN, PKTDROP, STREAM_RESET, AUTH) INIT ACK: Internet Protocol, Src: 192.168.1.80 (192.168.1.80), Dst: 192.168.1.20 (192.168.1.20) Supported Extensions parameter (Supported types: ASCONF, ASCONF_ACK, FORWARD_TSN, PKTDROP, STREAM_RESET, AUTH) Debug message: SCTP_SACK process cum_ack:45452434 num_seg:0 a_rwnd:1864135 Check for chunk output prw:1864135 tqe:1 tf=0 Send called addr:0xc591c980 send length 2 Calling ipv4 output routine from low level src addr:c0a80114 Destination is c0a80150 RTP route is 0xc5caaaf8 through IP output returns 0 m-c-o put out 1 Ok, we have put out 1 chunks USR Send complete qo:0 prw:1863859 unsent:18 tf:18 cooq:1 toqs:18 err:0 Ok laddr->ifa:0xc5baab00 is possible, asconf_queue_mgmt: inserted asconf ADD_IP_ADDRESS: IPv4 address: 192.168.1.50:0 m-c-o put out 0 Ok, we have put out 0 chunks sctp_input() length:28 iphlen:20 sctp_input(): Packet of length 48 received on wlan0 with csum_flags 0x0.

The result from wireshark and debug message have same results. -- View this message in context: http://freebsd.1045724.n5.nabble.com/SCTP-problems-in-sending-ASCONF-chunks-tp4929128p4931035.html Sent from the freebsd-net mailing list archive at Nabble.com. _______________________________________________ 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"
