A simple ICMP Echo implementation, based on golang.org/x/net/icmp.
- 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.
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 $name_of_library$
./ping hostname or sudo ./ping hostname
This command will create a binary executable file: Using this cli is very easy:
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
As the net packages is sending an "unprivileged" ping via UDP, it is recommended to have root privelages "sudo ./ping cloudflare.com"
