A reason you might be trying to avoid fragmentation, is that it does increase the likelyhood that the packet will go missing in it's entirety. More packets, just due to the higher overhead, would mean greater likelyhood of failure, let alone that each packet (even a fragment) represents a...
为了只抓包头,在wireshark的options里定义“Limit each packet to”设置为80(偏大的数字),TCP层、网络层和数据链路层的信息都可包括在内。 或者用tcpdump -s可以达到相同效果。 #为操作打标记,可以每一步完成ping (IP) -n 1 -l (number) wireshark的提示: (1)Packet size limited during capture 说明标记...
Just by increasing the UDP packet size from 512 to 1472 bytes. So if we increase the UDP packet size the number of call "recivefrom" minimize. and processor have enough time to handel the receive packets. now can any one tell me what is the maximum limit for udp packet size for ...
首先,可以通过netstat -st进行丢包情况确认:可以看到xxx packet receive errors和xxx receive buffer errors的数值一直在增长。 从错误信息的字面含义可知: packet receive errors一直增长,说明系统在收 UDP 包时,由于“一些原因”报错,导致丢包 receive buffer errors一直增长,说明 UDP接收缓冲区存在溢出报错,导致丢包 值...
程序可以通过填写 struct in_pktinfo 变量中的字段来指定要在 packet 上使用的源地址。如果程序是监听多个 IP 地址的服务端程序,那这是一个很有用的选项。在这种情况下,服务端可能想使用客户端连接服务端的那个 IP 地址来回复客户端, IP_PKTINFO 非常适合这种场景。

all import * # 创建UDP数据包 packet = IP(dst="目标IP地址")/UDP(dport=目标端口号)/Raw(load="数据包负载") # 发送UDP数据包 send(packet) 在这个示例中,我们可以通过调整load参数的内容来控制数据包的大小。通过增加或减少load参数的内容,可以发送不同大小的UDP数据包。 Scapy还提供了其他功能,如数据...
将多播设备(device)的索引(index)设置为发送(写)这个 packet 的设备索引,并且 packet 的源地址将设置为 multicast 源地址 如果目标地址不是一个组播地址,则发送 packet 的设备制定为inet->uc_index(单播), 除非用户使用IP_PKTINFO辅助消息覆盖了它。

Your packet size seems a little strange. If you aren't using jumbo frames, your packets are likely to be fragmented for transmission on the network. This may be the cause of your issue. Spitting the frames into parts of 1472 bytes or less would be more appropriate for an ethe...
