Dear freebsd-net all, I am a beginner of FreeBSD. I meet a problem in SCTP testing. I have two virtual machine, both installed FreeBSD 10 / i386 / with generic KERNEL (the host is CentOS 6.5 x86-64 with KVM) The first virtual machine named freetest0 and second is freetest1 freetest0 =3D freebsd 10 / i386 / the IF is vtnet2 192.168.6.100 freetest1 =3D freebsd 10 / i386 / the IF is vtnet2 192.168.6.110 I want to test the speed between to freetest(s) IF. But, the problem is they cannot get connected by SCTP. the TCP and UDP are well. Whatever I use iperf3 (with SCTP support) and netperfmeter, they cannot get connected by SCTP. #the server is freetest1 root@freetest1:~ # netstat -an -f inet Active Internet connections (including servers) Proto Recv-Q Send-Q Local Address Foreign Address (state) tcp46 0 0 *.9000 *.* LISTE= N tcp4 0 0 192.168.0.110.22 192.168.0.1.39754 ESTABLISHED tcp4 0 0 192.168.0.110.22 192.168.0.1.39752 ESTABLISHED tcp4 0 0 127.0.0.1.25 *.* LISTE= N tcp4 0 0 *.22 *.* LISTE= N udp46 0 0 *.9000 *.* udp4 0 0 *.514 *.* Active SCTP associations (including servers) Proto Type Local Address Foreign Address (state) sctp46 1to1 fe80::5054:ff:fe.9000 LISTEN 192.168.8.110.9000 fe80::5054:ff:fe.9000 192.168.6.110.9000 fe80::5054:ff:fe.9000 192.168.0.110.9000 127.0.0.1.9000 fe80::1.9000 ::1.9000 sctp46 1toN fe80::5054:ff:fe.9001 LISTEN 192.168.8.110.9001 fe80::5054:ff:fe.9001 192.168.6.110.9001 fe80::5054:ff:fe.9001 192.168.0.110.9001 127.0.0.1.9001 fe80::1.9001 ::1.9001 root@freetest0:~ # netperfmeter 192.168.6.110:9000 Network Performance Meter - Version 1.0 --------------------------------------- Active Mode: - Measurement ID =3D 4bc75bae - Remote Address =3D 192.168.6.110:9000 - Control Address =3D 192.168.6.110:9001 - connecting ... #<cannot get connected> root@freetest0:~ # tcpdump -i vtnet2 tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on vtnet2, link-type EN10MB (Ethernet), capture size 65535 bytes 14:11:03.839031 IP 192.168.6.100.55228 > 192.168.6.110.5201: Flags [S], seq 1318388212, win 65535, options [mss 1460,nop,wscale 6,sackOK,TS val 2652085 ecr 0], length 0 14:11:03.868787 IP 192.168.6.110.5201 > 192.168.6.100.55228: Flags [R.], seq 0, ack 1318388213, win 0, length 0 14:11:35.235362 IP 192.168.6.100.52018 > 192.168.6.110.9001: sctp (1) [INIT] [init tag: 3995201801] [rwnd: 1864135] [OS: 10] [MIS: 2048] [init TSN: 332259025] 14:11:38.256378 IP 192.168.6.100.52018 > 192.168.6.110.9001: sctp (1) [INIT] [init tag: 3995201801] [rwnd: 1864135] [OS: 10] [MIS: 2048] [init TSN: 332259025] 14:11:40.256418 IP 192.168.6.100.52018 > 192.168.6.110.9001: sctp (1) [INIT] [init tag: 3995201801] [rwnd: 1864135] [OS: 10] [MIS: 2048] [init TSN: 332259025] 14:11:44.256099 IP 192.168.6.100.52018 > 192.168.6.110.9001: sctp (1) [INIT] [init tag: 3995201801] [rwnd: 1864135] [OS: 10] [MIS: 2048] [init TSN: 332259025] 14:11:52.254442 IP 192.168.6.100.52018 > 192.168.6.110.9001: sctp (1) [INIT] [init tag: 3995201801] [rwnd: 1864135] [OS: 10] [MIS: 2048] [init TSN: 332259025] root@freetest1:~ # tcpdump -i vtnet2 tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on vtnet2, link-type EN10MB (Ethernet), capture size 65535 bytes 14:11:35.979349 IP 192.168.6.100.52018 > 192.168.6.110.9001: sctp (1) [INIT] [init tag: 3995201801] [rwnd: 1864135] [OS: 10] [MIS: 2048] [init TSN: 332259025] 14:11:39.000411 IP 192.168.6.100.52018 > 192.168.6.110.9001: sctp (1) [INIT] [init tag: 3995201801] [rwnd: 1864135] [OS: 10] [MIS: 2048] [init TSN: 332259025] 14:11:41.000495 IP 192.168.6.100.52018 > 192.168.6.110.9001: sctp (1) [INIT] [init tag: 3995201801] [rwnd: 1864135] [OS: 10] [MIS: 2048] [init TSN: 332259025] 14:11:45.000116 IP 192.168.6.100.52018 > 192.168.6.110.9001: sctp (1) [INIT] [init tag: 3995201801] [rwnd: 1864135] [OS: 10] [MIS: 2048] [init TSN: 332259025] 14:11:52.998491 IP 192.168.6.100.52018 > 192.168.6.110.9001: sctp (1) [INIT] [init tag: 3995201801] [rwnd: 1864135] [OS: 10] [MIS: 2048] [init TSN: 332259025] root@freetest0:~ # uname -a FreeBSD freetest0 10.0-RELEASE FreeBSD 10.0-RELEASE #0 r260789: Fri Jan 17 01:46:25 UTC 2014 root@snap.freebsd.org:/usr/obj/usr/src/sys/GENERIC i386 Could somebody help me?
