This patch reverses the behavior. --- src/qperf.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/qperf.c b/src/qperf.c index 89fe5b8f2eeb..4de0cceeb10f 100644 --- a/src/qperf.c +++ b/src/qperf.c @@ -1418,7 +1418,7 @@ server_listen(void) AI *ai; AI hints ={ .ai_flags = AI_PASSIVE | AI_NUMERICSERV, - .ai_family = AF_INET6, + .ai_family = AF_UNSPEC, .ai_socktype = SOCK_STREAM }; AI *ailist = getaddrinfo_port(0, ListenPort, &hints); -- 2.39.2
