Dear David,

I think the the sctpdlib is written in a way that te sctp_daemon runs locally.
It 'replaces' a kernel implementation, which would run locally. So why do
you want to run it remotely?

Neverless, it should technically be possible to run the daemon remotely, the
communication uses UDP. But it doesn't have flow control and that stuff.
Some comments from the sctpd developers?

Best regards
Michael

Hi,

If I start SCTP daemon on a remote machine and try to connect with
sctp_test_app, I'll get the output below. I noticed that if another SCTP
daemon is running locally, sctp_test_app will automatically connect to it
with source address 127.0.0.1.

Is there a way I can test a remote SCTP connection with the example tools
provided in the distribution?

Thank you,
