Observability or Security Solution Unmatched Network Packet Data for Zero Downtime Businesses Packets, Precision and Performanceare the Keys to resolving the unknown, unknown network issues Packets Every bit of every packet can be delivered, captured and analyzed, across the entire hybrid-network. ...
此函数用于解析交给它的packets。packet数据放在名为tvb的特殊缓存中。对此随着我们对协议细节了解的深入将会变得非常熟悉。packet_info结构包含有关协议的一般数据,我们应该在此更新信息。tree参数是细节解析发生的地方。 现在我们进行最小化的实现。第1行我们设置我们协议的文本,以示用户可以看到协议被识别了。另外唯一...
Libpcap is a packet capture library which can be used to sniff packets or network traffic over a network interface. Pcap Documentation gives a description of the methods and data structures available in the libpcap library. To install libpcap on your linux distro you can either download the so...
IFPDT/1/CRCRATIOEXCEED:OID [OID] The ratio of incoming CRC packets on the interface exceeds the threshold. (InterfaceIndex=[INTEGER], InterfaceName=[OCTET], Threshold=[OCTET], StatisticsInterval=[INTEGER], CRCPackets=[COUNTER64], TotalInPackets=[COUNTER64]) The percentage of received CRC packet...
cPacket's packet capture and analytics performance is a key differentiation compared to the competition. Packet Capture's high CTD rate enables it to write packets to storage as fast as they come over the network, while at the same time indexing for fast retrieval and analytics. Lossless Captur...

-- somebody's printing up packets:接收到ECHO-REPLY报文的数目大于发送ECHO-REQUEST报文的数目。 round-trip min/avg/max:响应时间的最小值、平均值、最大值,单位为ms(对于IPv4网络ping失败的时候不会打印该信息;对于IPv6网络ping失败的时候会打印round-trip min/avg/max = 0/0/0 ms)。
如果没有数据,且用户也允许等待,则将调用wait_for_more_packets()执行等待操作,它加入会让用户进程进入睡眠状态。 //file: net/ipv4/af_inet.c int inet_recvmsg(struct kiocb *iocb, struct socket *sock, struct msghdr *msg, size_t size, int flags){ ... err = sk->sk_prot->recvmsg(iocb, sk,...
