# The net/icmpinfo port

## icmpinfo-1.11 – look at the icmp messages received by the host

## Description

    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 useful
                     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)
