inet addr:10.10.8.95 Bcast:10.10.11.255 Mask:255.255.252.0
По кабеля имеется интернет eth0:
inet addr:10.10.8.146 Bcast:10.10.11.255 Mask:255.255.252.0
На удаленной машине запускаю пинг на WiFi:
ping 10.10.8.95
64 bytes from 10.10.8.95: icmp_seq=799 ttl=64 time=0.396 ms
64 bytes from 10.10.8.95: icmp_seq=800 ttl=64 time=0.409 ms
64 bytes from 10.10.8.95: icmp_seq=801 ttl=64 time=0.375 ms
Вроде все на ура проходит.
Однако сниффер на тестируемой линукс машине выдает:
10:11:37.970058 d4:ae:52:69:1c:04 > fc:c2:3d:00:d7:89, ethertype IPv4 (0x0800), length 98: 10.10.8.41 > 10.10.8.95: ICMP echo request, id 22853, seq 508, length 64
МАК адреса:
Удаленная машина eth0:
d4:ae:52:69:1c:04
Тестируемая машина eth0:
fc:c2:3d:00:d7:89
mlan0:
00:06:c6:48:4b:69
Получается что показывая пинг 10.10.8.41 > 10.10.8.95, на самом деле пинг идет через МАК интерфейс fc:c2:3d:00:d7:89 (eth0).
Что за хрень?
Помогите советом пожалуйста.
