Hi: I noticed that the light on my cable modem are flashing constantly like my network is very busy. My FBSD box acts as a firewall and a gateway. Nothing is connected to the lan but a single, inactive, pc. I'm afraid I don't know much about networks or how to debug tcpdump, but I would appreciate if someone could glance over the following snippet and tell me if there is anything I need to be concerned about. Thanks tcpdump 19:25:59.974705 eeyore1.1692 > vdgh1.mia.xpc-mii.net.http: . ack 1 win 17520 (DF) 19:25:59.976092 eeyore1.1692 > vdgh1.mia.xpc-mii.net.http: P 1:370(369) ack 1 win 17520 (DF) 19:26:00.046297 vdgh1.mia.xpc-mii.net.http > eeyore1.1692: . ack 370 win 64240 (DF) 19:26:00.046794 vdgh1.mia.xpc-mii.net.http > eeyore1.1692: P 1:48(47) ack 370 win 64240 (DF) 19:26:00.047213 vdgh1.mia.xpc-mii.net.http > eeyore1.1692: P 48:87(39) ack 370 win 64240 (DF) 19:26:00.060552 eeyore1.1692 > vdgh1.mia.xpc-mii.net.http: F 370:370(0) ack 87 win 17520 (DF) 19:26:00.075043 arp who-has 65.8.166.182 tell 65.8.166.1 19:26:00.081904 arp who-has 65.8.166.75 tell 65.8.166.1 19:26:00.084998 arp who-has 65.8.166.12 tell 65.8.166.1 19:26:00.123547 vdgh1.mia.xpc-mii.net.http > eeyore1.1692: . ack 371 win 64240 (DF) 19:26:00.123994 vdgh1.mia.xpc-mii.net.http > eeyore1.1692: F 87:87(0) ack 371 win 64240 (DF) 19:26:00.124141 eeyore1.1692 > vdgh1.mia.xpc-mii.net.http: . ack 88 win 17520 (DF) 19:26:00.127217 arp who-has ci845718-h.lxintn1.ky.home.com tell 24.14.41.1 19:26:00.127786 arp who-has 65.8.166.109 tell 65.8.166.1 19:26:00.135566 arp who-has 24.178.230.210 tell 24.178.230.1 19:26:00.151353 eeyore1.3775 > dns1.domain: 42860+ (45) 19:26:00.286186 dns1.domain > eeyore1.3775: 42860 NXDomain* 0/1/0 (129) 19:26:00.291819 eeyore1.3776 > dns1.domain: 42861+ (42) 19:26:00.396765 arp who-has 65.8.166.105 tell 65.8.166.1 19:26:00.456239 arp who-has 24.178.230.144 tell 24.178.230.1 19:26:00.569802 dns1.domain > eeyore1.3776: 42861 NXDomain* 0/1/0 (124) 19:26:00.582390 eeyore1.3777 > dns1.domain: 42862+ (43) 19:26:00.610029 arp who-has 24.178.230.102 tell 24.178.230.1 19:26:00.627598 arp who-has 24.178.230.211 tell 24.178.230.1 19:26:00.681116 dns1.domain > eeyore1.3777: 42862* 1/2/2 (183) 19:26:00.688916 eeyore1.3778 > dns1.domain: 42863+ (43) 19:26:00.785364 dns1.domain > eeyore1.3778: 42863 NXDomain* 0/1/0 (125) 19:26:00.791320 eeyore1.3779 > dns1.domain: 42864+ (43) 19:26:00.794975 arp who-has ct28536-a.lxintn1.ky.home.com tell 24.14.41.1 19:26:00.818941 arp who-has 65.8.166.36 tell 65.8.166.1 19:26:00.898762 dns1.domain > eeyore1.3779: 42864* 1/2/2 (183) 19:26:00.902201 eeyore1.3780 > dns1.domain: 42865+ (42) eeyore1 is my machine.
