Examples under windows (again) about usrsctp HOT 7 CLOSED

Regarding your first question: I'm not sure if 127.0.0.1 works on Windows.
Regarding your second question: Are you running this with root privileges? Are you behind a NAT? That might a problem with native SCTP. You might want to use Wireshark to capture the traffic. That might provide some more information.
@weinrank Can you test the above on a Windows system?

@pravic
I assume from the logfile that you already run the examples with administrative privileges - good.
The native SCTP mode needs administrative privileges while udp-encaps doesn't.

discard server and client
Don't use 127.0.0.1 - it doesn't work with Windows. Try using the IP of your local NIC and it should work.

http_client
The SCTP connection seems to be established: timer type 5 is the heartbeat timer.
As Michael Tüxen mentioned obove a wireshark tracefile would be helpful.

What happens if you disable IPv6 support in USRSCTP?
Are you using CMAKE?

from usrsctp.

Yea, cmake. I'll try without ipv6

I took it from manual. Whats difference between Linux and Windows with 127.0.0.1?

Are you running this with root privileges? Are you behind a NAT?

Yes. Yes.

@weinrank

Try using the IP of your local NIC and it should work.

It works. The local servers (like echo) works both with and without encapsulation.

What happens if you disable IPv6 support in USRSCTP?

Nothing good: "usrsctp_socket: Unknown error", because all examples uses AF_INET6.

The manual states that you can use 127.0.0.1 on Unix like OSes and not on Windows. Regarding the difference of 127.0.0.1 between Windows and Linux: On Unix like OSes there is an loopback interface
and an address. On Windows this seems to be different. I don't know why. (I don't know much about Windows).
Running native SCTP through NATs most likely is an issue. That is why we use UDP encapsulation there.

SCTP does not use/support NAT traversal?

Well, thanks for explanation.

from usrsctp.

NATs must support SCTP, one way of doing this is specified in https://tools.ietf.org/html/draft-ietf-tsvwg-natsupp-09. It is supported, as far as I know, in FreeBSD.
For legacy NAT traversal use UDP encapsulation.
