SCTP fails when multihoming is enabled #422

Open bozakov opened 6 years ago

bozakov commented 6 years ago

If the multihoming property is set SCTP (on Ubuntu 16.04) connection fails with 

[   0.494709][DBG] Failed to create he socket (family:2, type:1, prodocol:132)

To reproduce using tneat: Start a server:

./tneat -p 8888

On the client node create a property file test.prop containing the properties { "transport": { "value": "SCTP", "precedence": 1}, "multihoming": { "value": true, "precedence": 2} }. Then run:

./tneat 172.23.10.2 -p 8888 -P ./test.prop -v2 -n 100

BTW, using an MPTCP kernel I get a different error

[   0.849131][ERR] Failed to bindx fd XXX socket to IP. Error: Invalid argument

On MacOS (HighSierra 10.13.2) I get the same error as with the one mentioned about Ubuntu 16.04 on the client side. However on the server side, I get this error:

[ 0.003066][ERR] nt_listen_via_kernel: opening listening socket failed - Protocol not supported

Even though I have installed the usrsctp-neat and usrsctp support flag is enabled in CMakeList.txt.

On Ubuntu 16.04 LTS, with a similar setup as above, I get this error though:

usrsctp_sendv: No such file or directory

Can you tell me, which setup you used. Which examples did you start? What did you do on the client and on the server side. What does your property list look like?
