Rafael H. Schloming commented on PROTON-791: -------------------------------------------- The reactor code is just delegating to the existing API provided by proton/io.h. It passes "0.0.0.0" into the bind and uses "localhost" on the connect. It looks like somehow "localhost" is getting turned into "::1". I'm not sure exactly how to fix this or even where the bug is exactly. I would naively expect binding to "0.0.0.0" and connecting to "localhost" to just work, but I'm not super up to date on IPv6 stuff. > c-reactor-tests fails because it listens to an IPv4 socket but connects to an > IPv6 socket > ----------------------------------------------------------------------------------------- > > Key: PROTON-791 > URL: https://issues.apache.org/jira/browse/PROTON-791 > Project: Qpid Proton > Issue Type: Bug > Components: proton-c > Reporter: Andrew Stitcher > Assignee: Rafael H.
