Witam, mam problem, z AP-ekiem GN-AP01G 54Mbps AirCruiser G Access Point Gigabyta. Na wstępie prosze nie udzielac odpowiedzi RTFM i "google odpowie". Sprawdzałem i odpowiedzi nie znalazlem. Otóż lacze tego AP w WDS-ie z Tonziakiem na 2.4GHz. Wszystko dziala cycuś glancuś, ale rutynowa kontrola ruchu sieciowego wykazala cos ciekawego: root@SG:/# tcpdump -ln -i eth1 'host 85.14.100.190' tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on eth1, link-type EN10MB (Ethernet), capture size 96 bytes 21:20:32.982450 IP 85.14.100.190 > 85.14.103.187: icmp 36: 85.14.103.255 udp port 35072 unreachable 21:20:33.011286 IP 85.14.100.190 > 85.14.103.187: icmp 36: 85.14.103.255 udp port 35072 unreachable 21:20:33.047653 IP 85.14.100.190 > 85.14.102.234: icmp 36: 85.14.102.255 udp port 35072 unreachable 21:20:33.716489 IP 85.14.100.190 > 85.14.103.187: icmp 36: 85.14.103.255 udp port 35072 unreachable 21:20:33.757228 IP 85.14.100.190 > 85.14.102.177: icmp 36: 85.14.102.255 udp port 35328 unreachable Wyglada na skanowanie sieci . Pomyslalem sobie ktos sie pod niego podszywa. Wiec sprawdzam jego mac ( dla pewnosci spisalem go z urzadzenia a nie za pomoca arp ) i mam 00:16:E6:3A:6F:52. Robie: root@SG:/# tcpdump -i eth1 'host 85.14.100.190' -ln -e tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on eth1, link-type EN10MB (Ethernet), capture size 96 bytes 21:27:01.558905 00:16:e6:3a:6f:54 > 00:30:4f:3b:1b:bf, ethertype IPv4 (0x0800), length 70: IP 85.14.100.190 > 85.14.102.101: icmp 36: 85.14.102.255 udp port 35328 unreachable 21:27:01.559014 00:30:4f:3b:1b:bf > 00:e0:4c:32:26:59, ethertype IPv4 (0x0800), length 70: IP 85.14.100.190 > 85.14.102.101: icmp 36: 85.14.102.255 udp port 35328 unreachable 21:27:04.851755 00:16:e6:3a:6f:54 > 00:30:4f:3b:1b:bf, ethertype IPv4 (0x0800), length 70: IP 85.14.100.190 > 85.14.101.226: icmp 36: 85.14.101.255 udp port 35072 unreachable 21:27:04.853095 00:30:4f:3b:1b:bf > 00:0b:6a:ee:8c:86, ethertype IPv4 (0x0800), length 70: IP 85.14.100.190 > 85.14.101.226: icmp 36: 85.14.101.255 udp port 35072 unreachable 21:27:05.608356 00:16:e6:3a:6f:54 > 00:30:4f:3b:1b:bf, ethertype IPv4 (0x0800), length 70: IP 85.14.100.190 > 85.14.101.226: icmp 36: 85.14.101.255 udp port 35072 unreachable Gdzie 00:30:4f:3b:1b:bf to mac sieciowki na routerze ktory jest dla tego AP bramą. Skoro maki sie zgadzaja to wiadomo ze raczej nie mowy o podszyciu ( jakby ktos sie podszywal to albo bylby inny MAC albo nie daloby sie wejsc na AP ). Pytania brzmią: 1) What tha fuck is going on ? 2) Why ? 3) Jak to wyłączyc ? Wersja softu to: 1.10E pzdr. Armando
