Hi,
just looked through some ICMP code in icmp_socket.c and found a little bit weird TTL:
218 if (icmp_packet->version != COMPAT_VERSION) { 219 icmp_packet->msg_type = PARAMETER_PROBLEM; 220 icmp_packet->ttl = COMPAT_VERSION; 221 bat_socket_add_packet(socket_client, icmp_packet, packet_len); 222 goto free_skb; 223 }
It was introduced by dba95eb270ff9674326865a20d25921c69c04d6c. My guess is that TTL should be used.
Kind regards, Sven
