9 All layer 4 packets and ICMP packets will change these counters, but
33 ICMP and so on. If no one listens on a raw socket, only kernel
127 ICMP counters
137 would be increased even if the ICMP packet has an invalid type. The
138 ICMP output path will check the header of a raw socket, so the
142 * ICMP named types
144 | These counters include most of common ICMP types, they are:
192 Every ICMP type has two counters: 'In' and 'Out'. E.g., for the ICMP
197 * ICMP numeric types
200 ICMP type number. These counters track all kinds of ICMP packets. The
201 ICMP type number definition could be found in the `ICMP parameters`_
206 For example, if the Linux kernel sends an ICMP Echo packet, the
207 IcmpMsgOutType8 would increase 1. And if kernel gets an ICMP Echo Reply
212 This counter indicates the checksum of the ICMP packet is
224 When an error occurs in the ICMP packet handler path, these two
229 relationship of the ICMP counters
234 receives an ICMP packet, kernel follows below logic:
1063 The Linux server sent an ICMP Echo packet, so IpOutRequests,
1065 server got ICMP Echo Reply from 8.8.8.8, so IpInReceives, IcmpInMsgs,
1066 IcmpInEchoReps and IcmpMsgInType0 were increased 1. The ICMP Echo Reply
1067 was passed to the ICMP layer via IP layer, so IpInDelivers was
1068 increased 1. The default ping data size is 48, so an ICMP Echo packet
1073 * 16 bytes ICMP header
1568 to server B. When server B receives such packet, it might send a ICMP
1629 8.8.8.8, so server B increase IpExtInNoRoutes and sent the "ICMP
