icmpinfo

Looks at the icmp messages received by the host

ICMPINFO: icmpinfo is a tool for looking at the ICMP messages received on the running host. The source code comes from an heavily modified BSD ping source. USAGE: icmpinfo o Gives info about weird packets only [mainly icmp_unreachable]. icmpinfo -v o Gives info about all ICMP packets [that includes your own traceroutes...] except pings (icmp_echo_reply). icmpinfo -vv o To see pings too. icmpinfo -vvv o Will add an ascci/hexa dump of the packet. icmpinfo -n o Avoids name queries (faster, lighter). icmpinfo -p o Avoids port number to service name queries (faster, lighter). icmpinfo -s o Also decode the ip_src field which is the address of the interface receiving the packet. This option is not usefull for hosts with a single network interface. icmpinfo -l o Run like a daemon (forks) and output to SYSLOG. (It now checks that you are root for that)
