I can't capture any package sent from my computer; I didn't set any filter and I'm sure the interface captured was right. For example, I ping another IP from my PC, a REPLY package can be captured, but the REQUEST package sent from my PC cannot be captured.Any packages sent from my PC cannot be captured,such as ICMP,TCP,HTTP, and so on. Look forward to your reply soon. Thanks a lot! asked 29 Apr '15, 12:28  ncu1121zhb |
One Answer:
How do you capture, wireless or wired? When wireless, you can't capture your outgoing packets with the same WiFi card because it can either send or receive (=capture). If wired, check/disable your local firewall/security software which may omit packets from the capture process. answered 29 Apr '15, 12:56  Jasper ♦♦ |
It sounds like you have more than one interface to the outside world and for whatever reason you are capturing on the one that the reply is returning on. If it were me, I would first capture on the "any" interface to see if there is some asymmetric signaling going on.
