How can I do a ping every 500 ms?

Question

By default the time delay between two pings is equal to 1 second. My need is to reduce the delay between two pings to 500 ms (0.5 seconds). Is there any way to do this?

Answer 1

You can take the System.Net.NetworkInformation.Ping class and wrap it in a PowerShell function. I kept it very easy, you can tinker with it to get the output you want.

Here's the function:

• Computername accepts internal + external IP Adresses, ComputerNames, URLs etc.
• Count = How many ping packets to send
• Timeout specifies the maximum number of milliseconds (after sending the echo message) to wait for the ICMP echo reply message.
• Interval = How many milliseconds to wait before next ping.

.

Function New-IntervalPing {

    [Alias("iping")]
    Param(
        [string]$ComputerName,
        [int]$Count = 4,
        [int]$TimeOut = 100,
        [int]$Interval = 500
    )

    1..$Count | ForEach-Object {
        $Ping = [System.Net.NetworkInformation.Ping]::New()
        $Ping.Send($ComputerName,$TimeOut)
        start-sleep -Milliseconds $Interval
    }
}

usage:

PS C:\Users\SimonS> iping google.com -count 2 -interval 300


Status        : Success
Address       : 172.217.168.14
RoundtripTime : 6
Options       : System.Net.NetworkInformation.PingOptions
Buffer        : {97, 98, 99, 100...}

Status        : Success
Address       : 172.217.168.14
RoundtripTime : 4
Options       : System.Net.NetworkInformation.PingOptions
Buffer        : {97, 98, 99, 100...}

Answer 2

On Linux it is possible (recently minimum time was changed to 200ms = 0.2):

ping -i 0.2 server.com

Root can issue shorter time:

ping -i 0.01 server.com

Answer 3

You can do this with nping (from the makers of nmap)

1. First download and install the nmap package which includes nping.
2. In a command prompt change the directory to C:\Program Files (x86)\Nmap
3. Now run the following command: nping --delay 500ms --count 0 <target ip address>
   (the --count 0 option sets it to a continuous ping)

....from Nping Reference Guide:

Usage: nping [Probe mode] [Options] {target specification}
....
....
TIMING AND PERFORMANCE:
  Options which take <time> are in seconds, or append 'ms' (milliseconds),
  's' (seconds), 'm' (minutes), or 'h' (hours) to the value (e.g. 30m, 0.25h).
  --delay <time>                   : Adjust delay between probes.
  --rate  <rate>                   : Send num packets per second.

• In PowerShell

$cnt=0; while ($cnt -le 9) {$cnt++; Start-Sleep -MilliSeconds 500; Test-Connection 1.1.1.1 -Count 1}

• One option using aliases:

$cnt=0;while($cnt -le 9){$cnt++;Test-Connection 1.1.1.1  -Cou 1; sleep -M 500} 

Super golfed version from @wasif-hasan comment suggestion:

0..9|%{test-Connection 1.1.1.1 -cou 1;sleep -m 500}

• Some further reading for PowerShell:

  [√] While | $cnt+

  [√] Test-Connection

  [√] Start-Sleep | Sleep

  [√] Remove-Variable | Rv

• In Bat/CMD:

@echo off 

:loop
pathping 127.1 -n -q 1 -p 500 >nul 2>nul 
ping 151.101.193.69 -n 1 -4 & goto=:loop

• Or with a predefined ping/loop limit:

@echo off & setlocal

:loop
pathping 127.1 -n -q 1 -p 500 >nul 2>nul
ping 1.1.1.1 -n 1 -4 & set /a "_cnt+=1+0"
if %_cnt% leq 10 (goto:loop)else goto:eof

Use pathping from Microsoft and comes with Windows

C:\Users\ecker>where pathping
C:\Windows\System32\PATHPING.EXE

---

C:\Users\ecker>PATHPING.EXE /?
Usage: pathping [-g host-list] [-h maximum_hops] [-i address] [-n]
                [-p period] [-q num_queries] [-w timeout]
                [-4] [-6] target_name

Options:
    -g host-list     Loose source route along host-list.
    -h maximum_hops  Maximum number of hops to search for target.
    -i address       Use the specified source address.
    -n               Do not resolve addresses to hostnames.
    -p period        Wait period milliseconds between pings.
    -q num_queries   Number of queries per hop.
    -w timeout       Wait timeout milliseconds for each reply.
    -4               Force using IPv4.
    -6               Force using IPv6.

---

Obs.: When -p is specified, pings are sent individually to each intermediate hop. When -w is specified, multiple pings can be sent in parallel. It is therefore possible to choose a Timeout parameter that is less than the wait Period * Number of hops.

Answer 5

You can't change the time between each ping request in the Windows command line. You'll need a 3rd party tool like fping or TruePing

Also see https://serverfault.com/questions/200468/how-can-i-set-a-short-timeout-with-the-ping-command

Answer 6

A very simple way to do this is simply to run two pings each in their own window. (Not strictly 1 every 500ms, but it would be 2 per second.)

This gets cumbersome fast, but something like 5 at once is possible.

Answer 7

Thanks to @SimonS for accepted answer
I rewrite & improve it for personally usage

• flood mode
• wait for server response
• but dont wait betweens
• result just in one line
• different colors usage
• resize window too

Function New-IntervalPing {

    [Alias("fping")]
    Param(
        [string]$Target,
        [int]$TimeOut = 200
    )

    mode 20,64
    while(1) {
        $Ping = [System.Net.NetworkInformation.Ping]::New()
        $Res = $Ping.Send($Target,$TimeOut,[byte[]]::new(1))
        Write-Host -NoNewline $Target ">  "
        $color = if($Res.RoundtripTime -eq "0"){"red"}else{"green"}
        Write-Host -ForegroundColor $color $Res.RoundtripTime
    }
}

Usage

fping 1.0.0.1

if you dont like window size changes, can comment it like # mode 20,64
