This is a basic implementation of the ping utility. IPv4 and IPv6 are both supported. Examples of usage include:
The following command pings 8.8.8.8 forever, with a one second interval between pings.
mini-ping 8.8.8.8
The following command pings google 10 times before stopping, again with a one second interval.
mini-ping -c 10 www.google.com
The following command pings the IPv6 address of google with a 64 byte payload (72 bytes overall) with an interval of 0.5 seconds.
mini-ping -s 64 -i 0.5 2001:4860:4860::8888
mini-ping [ -c count ] [ -i interval ] [ -s packetsize ] [ -t ttl ] [ -w deadline ] destination
-c count
: Stop after sending count packets.
-i interval
: Wait interval seconds between sending each packet. The default is to wait for one second between each packet normally
-s packetsize
: Specifies the number of data bytes to be sent. The default is 56, which translates into 64 ICMP data bytes when combined with the 8 bytes of ICMP header data.
-t ttl
: Set the IP Time to Live.
-w deadline
: Specify a timeout, in seconds, before ping exits regardless of how many packets have been sent or received.
To build this project, please ensure that you have installed Go. This project has been tested using Go v1.14.2 on Ubuntu. Additional packages necessary include the extra networking features, which may be installed using
go get golang.org/x/net/ipv4
go get golang.org/x/net/ipv6
go get golang.org/x/net/icmp
After this, you can build using
go build mini-ping.go
The reported values for TTL on Windows are currently inaccurate (they always report zero). This is due to the control flags in Go not being able to be set on Windows (since it has not been implemented for Windows in the Go library yet).
