...e other dhcp clients (be it DISCOVER or REQUEST) and from that point on, receive nothing else. Now, looking at the code (under usr/kinit/ipconfig for those following at home): packet.c: packet_recv() | ? | if (udp->source != htons(cfg_remote_port) || | udp->dest != htons(cfg_local_port)) | goto free_pkt; | ? | free_pkt: | free(ip); | return 0; | ? Which means in case of source/dest mismatch (which is the case when a message from another client is received), 0 is returned. Now, looking at the callers: bootp_proto.c: bootp_recv_reply() & dhcp_p...
