Hi, I try to add the selection of the interfaces to serve on MHD. I was using MHD_USE_EPOLL and was managing to include the epoll in the external main loop with MHD_get_daemon_info(daemon, MHD_DAEMON_INFO_EPOLL_FD_LINUX_ONLY) -> listen_fd
But it appears that setting MHD_USE_EPOLL and MHD_USE_NO_LISTEN_SOCKET together is unsupported. So it doesn't work. listen_fd is -1 always. I think that my expectation is valuable. Do you agree? Best regards José Bollo
