freebsd - SCTP INIT failed -


i have 2 virtual machine, both installed freebsd 10 / i386 / generic kernel (the host centos 6.5 x86-64 kvm)

the first virtual machine named freetest0 , second freetest1

freetest0 = freebsd 10 / i386 / if vtnet2 192.168.6.100 freetest1 = freebsd 10 / i386 / if vtnet2 192.168.6.110

i want test speed between freetest(s) if. but, problem cannot connected sctp. tcp , udp well.

whatever use iperf3 (with sctp support) , netperfmeter, cannot connected sctp.
