Hi, Peter.
GW-77.93.52.9/29 <---------> 77.93.52.10/29-MyServer
00:1b:21:45:da:b8
I have change LAN and not it is:
GW-77.93.52.9/29 <---------> 77.93.52.10/29-MyServer
00:30:67:5a:44:72
ping 77.93.52.9
^C
--- 77.93.52.9 ping statistics ---
3 packets transmitted, 0 packets received, 100.0% packet loss
tcpdump -n -i re0 arp
15:39:46.540277 ARP, Request who-has 77.93.52.10 (00:1b:21:45:da:b8) tell 77.93.52.9, length 46
0x0000: 001b 2145 dab8 0006 d602 e0c0 0806 0001 ..!E............
0x0010: 0800 0604 0001 0006 d602 e0c0 4d5d 3409 ............M]4.
0x0020: 001b 2145 dab8 4d5d 340a 0000 0000 0000 ..!E..M]4.......
0x0030: 0000 0000 0000 0000 0000 0000 ............
77.93.52.9 thinks that 77.93.52.10 have old MAC 00:1b:21:45:da:b8
Why freebsd do not answer for 'who-has' packet?
