加拿大华人论坛 德国留学移民签证想请教这里Linux高手一个问题
在加拿大
我在作DA,目前遇见个对我来说很棘手的问题,我想在Linux的Link Layer 下取得数据包发送成功后的ack. 请问高手,在哪可以获得?Tutor建议我在无线网卡驱动(orinoco)里找,我用了printf想显示结果,结果数据包发送成功,可我啥结果也没获得。
想请问,有谁也在作无线网吗?有没有在link layer下好的求FER的方法(我需要ack就是为了求FER),谢谢。
如果和谁作的课题差不多,我们也可以一起讨论讨论。

Sorry. For wireless channel, i don't know much. Is there really a ACK for a Request just like what happens in LAN?
Oh, a whitepaper about TCP ACK in wireless

10. Capturing packets on wireless LANs http://www.wireshark.org/faq.html#q10.1
Another option is, socket programming with PCAP library packet http://www.tcpdump.org/ They works perfectly in ethernet LAN but it is hard to say, anywhere special and different for WLAN.
