Ping-Cli

A simple ICMP Echo implementation, based on golang.org/x/net/icmp.

Feature:

• IPv4 and IPv6 support
• Arguement to set TTL and see Time Limit Excedded Messages

It sends ICMP packet(s) and waits for a response. When it's finished, it prints the summary based of packet sent, received and lost.

Usage:

Installation

For installing you only need three external libraries:

• "golang.org/x/net/icmp"
• "golang.org/x/net/ipv4"
• "golang.org/x/net/ipv6"

You can download these using go get $name_of_library$

Building

./ping hostname or sudo ./ping hostname

This command will create a binary executable file: Using this cli is very easy:

Arguements

Usage:

ping [-i interval] [-T TTL Limit][--p] host

example pinging to cloudflare.com:
./ping www.cloudflare.com

# For privelage use "--p" flag:
sudo ./ping --p www.cloudflare.com

# For Interval use "-p" flag:
sudo ./ping -i 500ms www.cloudflare.com

## For TTL use "-T" flag:
sudo ./ping -T 10 www.cloudflare.com

Note: Default TTL is set to 50, if IMCP Time Limit Exceeded Message is Received, it will be printed and TTL will be increased by 1 until first Echo Request is received.

# By default interval is set = 1ms

Troubleshoot:

As the net packages is sending an "unprivileged" ping via UDP, it is recommended to have root privelages "sudo ./ping cloudflare.com"
