Icmp client

A very simplified IPv4 ping clone written in Golang for Linux systems.

How it works

• It implements the IPv4 protocol and the ECHO and ECHO REPLY message formats of the ICMP protocol.

• It accepts IPv4 addresses and domain names, such as google.com, microsoft.com, etc.

• It uses a default packet size of 84 bytes (IPv4 (20 bytes) + ICMP[headers (8 bytes) + [data + padding] (56 bytes)]).

• The data field contains a struct timeval with the current timestamp.

Build

To build this software, you will need root priviledges. The root priviledges are necessary because of the use of raw sockets that require a special capability called: CAP_NET_RAW.

In your terminal type: sudo make.

Input

Currently, the accepted parameters are:

• -domain=<ipv4 address|domain name address>

• -requests=<amount of requests>. Default is 2 requests
