Why would getnameinfo(NI_NUMERICHOST) fail here? The code in ikev2_msg.c is: --8<-- log_info("%s: %s %s from %s to %s msgid %u, %ld bytes%s", __func__, print_map(exchange, ikev2_exchange_map), (flags & IKEV2_FLAG_RESPONSE) ? "response" : "request", print_host((struct sockaddr *)&msg->msg_local, NULL, 0), print_host((struct sockaddr *)&msg->msg_peer, NULL, 0), betoh32(hdr->ike_msgid), ibuf_length(buf), isnatt ? ", NAT-T" : ""); -->8-- Maybe msg->msg_local is corrupt? -- jca | PGP : 0x1524E7EE / 5135 92C1 AD36 5293 2BDF DDCC 0DFA 74AE 1524 E7EE
