icmpv6_send: no reply to icmp error 文心快码BaiduComate 针对你提出的“icmpv6_send: no reply to icmp error”问题,这通常表明在尝试使用ICMPv6协议向目标主机发送消息时,没有收到任何回复。以下是根据你的提示,分点进行的详细分析和建议: 检查网络连接状态: 确保你的设备已连接到IPv6网络。 使用ifconfig或...
最近在查看MT7621老毛子固件日志的时候发现莫名其妙出现 icmpv6_send: no reply to icmp error 的错误，也不知道具体出现这条bug信息原因 因为项目一直都是在正常使用IPv6的功能，所以只好把IPv6或相关的打印信息给关闭了，等后续时间允许再来详细研究下，先记录一下 Jul 18 16:26:38 crond[7964]: crond (busyb...
在ICMPv6 中,使用icmpv6_send()和icmpv6_echo_reply()发送消息,其中icmpv6_echo_reply只是回复消息用,主力还是icmpv6_send():发送一个ICMP消息作为对错误数据包的响应 voidicmp6_send(structsk_buff *skb, u8 type, u8 code, __u32 info,conststructin6_addr *force_saddr,conststructinet6_skb_parm *parm)...
ICMPv6是互联网控制消息协议第6版(Internet Control Message Protocol version 6)的缩写,它是IPv6协议族中的一个重要协议,与IPv4中的ICMPv4协议相对应。ICMPv6同样用于传递网络层的控制和错误信息,辅助IPv6协议完成高效、可靠的数据传输任务。 与ICMPv4类似,ICMPv6报文封装在IPv6数据报中进行传输。报文主要由报头和数...
Under normal circumstances, a device can send and receive ICMPv6 messages properly. However, when network traffic is heavy, host unreachable or port unreachable events frequently occur, leading to a surge in ICMPv6 messages, which burdens the network and degrades device performance. Network attackers...

If an IPv6 node cannot complete the processing of a packet because it has a problem identifying a field in the IPv6 header or in an Extension header, it must discard the packet, and it should send an ICMP Parameter Problem message back to the source of the problem packet. This type of...
