Hi,

could you try the following patch?

diff --git a/src/skins/posix/rtdm.c b/src/skins/posix/rtdm.c
index aa23737..c6326f0 100644

 	if (ret >= 0)
 		ret += __pse51_rtdm_fd_start;
-	else if (ret == -EAFNOSUPPORT || ret == -ENOSYS) {
+	else if (ret == -EAFNOSUPPORT || ret == -EPROTONOSUPPORT || ret == -ENOSYS) {
 		ret = __real_socket(protocol_family, socket_type, protocol);
