Hi, I'm new to Open vswitch and I'm trying to setup an SCTP connection between two VM, but for some reason the SCTP INIT packet got dropped in the veth pair, anyone has some suggestion what that could be? System setup:2 Ubuntu 14.04 VMs running on two different Linux hosts, and it's deployed with OpenStack Open vSwith version:ovs-vsctl (Open vSwitch) 2.3.1 Compiled Jun 24 2015 18:40:03 DB Schema 7.6.2
Test:I use sctp_test script to setup server in one VM and client in the other.When checking the tcpdump, I can see the INIT message is sent out from the VM, passing the Linux bridge, then it's lost. But the ping went through OK. So any idea? -------------------------------------------------------------------------------------------- tcpdump -i qbrf2abf66d-09 host 10.241.1.201 -ne -vvv 15:09:52.607256 bb:aa:3e:fa:11:c8 > bb:aa:3e:72:11:66, ethertype IPv4 (0x0800), length 82: (tos 0x2,ECT(0), ttl 64, id 0, offset 0, flags [DF], proto SCTP (132), length 68) 10.241.1.202.36000 > 10.241.1.201.36001: sctp 1) [INIT] [init tag: 1545368510] [rwnd: 81920] [OS: 10] [MIS: 65535] [init TSN: 1218271067] tcpdump -i qvbf2abf66d-09 host 10.241.1.201 -ne -vvv (nothing, except ICMP or ARP packets) -------------------------------------------------------------------------------------------- Regards,Tonny
