pinger
ICMP/UDP ping library for Go
Example
package main
import (
"github.com/arvinkulagin/pinger"
"log"
"os"
"fmt"
"time"
)
func main() {
if len(os.Args) < 2 {
fmt.Println("You must specify remote host address")
os.Exit(1)
}
raddr := os.Args[1]
p, err := pinger.NewPinger("udp", "0.0.0.0")
if err != nil {
log.Fatal(err)
}
for {
time.Sleep(1 * time.Second)
pong, err := p.Ping(raddr)
if err != nil {
log.Println(err)
continue
}
fmt.Printf("%d Bytes from %s: icmp_seq=%d time=%f\n", pong.Size, pong.Peer.String(), pong.Seq, pong.RTT.Seconds())
}
}

Types ¶
type ICMP4Pinger ¶
type ICMP4Pinger struct {
// contains filtered or unexported fields
}
func NewICMP4Pinger ¶
func NewICMP4Pinger(laddr string) (*ICMP4Pinger, error)
Returns new ICMP4Pinger. laddr is local ip address for listening.
func (*ICMP4Pinger) Ping ¶
func (i *ICMP4Pinger) Ping(raddr string) (Pong, error)
Send Echo-Request to remote host and wait Echo-Reply. raddr is an address of remote host.
func (*ICMP4Pinger) ResetCounter ¶
func (i *ICMP4Pinger) ResetCounter()
Sets ICMP4Pinger counter to 0. Counter increments with each Ping() call. Counter value is set to Seq field in Echo-Request.
func (*ICMP4Pinger) SetTimeout ¶
func (i *ICMP4Pinger) SetTimeout(d time.Duration)
Sets ICMP4Pinger timeout. Timeout is a waiting time for a Echo-Reply from a remote host.
type UDP4Pinger ¶
type UDP4Pinger struct {
// contains filtered or unexported fields
}
func NewUDP4Pinger ¶
func NewUDP4Pinger(laddr string) (*UDP4Pinger, error)
Returns new UDP4Pinger. laddr is local ip address for listening.
func (*UDP4Pinger) Ping ¶
func (i *UDP4Pinger) Ping(raddr string) (Pong, error)
Send Echo-Request to remote host and wait Echo-Reply. raddr is an address of remote host.
func (*UDP4Pinger) ResetCounter ¶
func (i *UDP4Pinger) ResetCounter()
Sets UDP4Pinger counter to 0. Counter increments with each Ping() call. Counter value is set to Seq field in Echo-Request.
func (*UDP4Pinger) SetTimeout ¶
func (i *UDP4Pinger) SetTimeout(d time.Duration)
Sets UDP4Pinger timeout. Timeout is a waiting time for a Echo-Reply from a remote host.
