I'm running 4.3BSD on the SIMH VAX-11/780 emulator, and I'm having some issues with the emulated DEUNA Ethernet adapter. I'm using SIMH version 3.8 on Windows XP.<br><br>I've got two issues:<br><br>1. The Ethernet adapter does not appear to respond to broadcasts (i.e. destination address ff:ff:ff:ff:ff:ff), so the system does not answer ARP requests.<br>
<br>Here's an example tcpdump output. The client is at IP address <a href="http://192.168.1.57" target="_blank">192.168.1.57</a>, and the 4.3BSD machine is at <a href="http://192.168.1.70" target="_blank">192.168.1.70</a>:<br>
<br>18:27:03.623364 00:0c:29:01:67:5a > ff:ff:ff:ff:ff:ff, ethertype ARP (0x0806), length 42: arp who-has <a href="http://192.168.1.70" target="_blank">192.168.1.70</a> tell <a href="http://192.168.1.57" target="_blank">192.168.1.57</a><br>
18:27:03.725393 00:0c:29:01:67:5a > ff:ff:ff:ff:ff:ff, ethertype ARP (0x0806), length 42: arp who-has <a href="http://192.168.1.70" target="_blank">192.168.1.70</a> tell <a href="http://192.168.1.57" target="_blank">192.168.1.57</a><br>
<br>2. The Ethernet adapter responds to packets sent to its own address, but replies from seemingly random source addresses.<br><br>Here's an example of an ARP request sent to the SIMH system's MAC address of 08:00:2b:12:34:56. We see that it replies with the correct MAC address in the ARP packet, but the source address in the Ethernet frame is aa:fd:00:00:00:00<br>
<br>18:29:48.059696 00:0c:29:01:67:5a > 08:00:2b:12:34:56, ethertype ARP (0x0806), length 42: arp who-has <a href="http://192.168.1.70" target="_blank">192.168.1.70</a> tell <a href="http://192.168.1.57" target="_blank">192.168.1.57</a><br>
18:29:48.060160 aa:fd:00:00:00:00 > 00:0c:29:01:67:5a, ethertype ARP (0x0806), length 60: arp reply <a href="http://192.168.1.70" target="_blank">192.168.1.70</a> is-at 08:00:2b:12:34:56<br><br>Sending another directed ARP request gets a reply with a different source MAC address:<br>
<br>18:32:05.439533 00:0c:29:01:67:5a > 08:00:2b:12:34:56, ethertype ARP (0x0806), length 42: arp who-has <a href="http://192.168.1.70" target="_blank">192.168.1.70</a> tell <a href="http://192.168.1.57" target="_blank">192.168.1.57</a><br>
18:32:05.445380 ab:b1:00:00:00:00 > 00:0c:29:01:67:5a, ethertype ARP (0x0806), length 60: arp reply <a href="http://192.168.1.70" target="_blank">192.168.1.70</a> is-at 08:00:2b:12:34:56<br><br>If I put a static ARP mapping on the client, I can telnet to the SIMH system and login. The telnet session also uses random source addresses in the ethernet header, but surprisingly still works OK:<br>
