go-ping-ttl

Utility library for sending ICMP pings to IPv4 or IPv6 destinations with TTL control.

Usage

1. Create an instance of the Pinger with pingttl.New()
2. Call .Ping() with a context and the address of the host you want to ping.

Your entire application should have a single instance of Pinger. Store it globally (🤢), or preferably, inject it as a dependency!

pinger := pingttl.New()

ip, err := net.ResolveIPAddr("ip4", "google.com")
if err != nil {
    return err
}

ctx, cancel := context.WithTimeout(context.Background(), time.Second * 5)
defer cancel()

// Providing 0 as a TTL will default to a sane value (64)
res, err := pinger.Ping(ctx, ip, 0)
if err != nil {
    return err
}

log.Printf("%s", res.Duration)
