But why would you want to do that? One case is when you know exactly how long you want a process to run for. You might have a habit of setting processes running, minimizing the terminal window, and forgetting about them.

Some programs—even simple utilities—can generate network traffic at levels that can impede the performance of your network. Or they can tie up the resources on a target device, slowing down its performance.

After 15 seconds timeout terminates the ping session and we are returned to the command line prompt. Some data capture files can grow big very quickly. To prevent such files becoming unwieldy or even problematic in size, limit the amount of time the capture program is allowed to run.

On the test machines that this article was researched on, tcpdump was already installed in Ubuntu Linux and Fedora Linux. It had to be installed on Manjaro Linux and Arch Linux, with the following command:.

And 10 seconds comes and goes and tcpdump is still running, and capture. Checking the size of capture. That file was growing fast! This politely asks the program to terminate. When that happens, we need to tell timeout to be a little more forceful. To do this, we use the -k kill after option.

The -k option requires a time value as a parameter. Well-behaved programs pass a value back to the shell when they terminate. This is known as an exit code. Typically this is used to tell the shell—or whatever process launched the program— whether problems were encountered by the program as it ran.The ping command is a Command Prompt command used to test the ability of the source computer to reach a specified destination computer.

The ping command is usually used as a simple way verify that a computer can communicate over the network with another computer or network device. How many of those responses are returned, and how long it takes for them to return, are the two major pieces of information that the ping command provides.

If you execute the ping command without this option, four requests will be sent. Beginning in Windows 7, this option no longer functions but still exists for compatibility reasons.

The maximum value for count is 4 meaning that only the first four hops can be time stamped. Note: The -f, -v, -r, -s, -j, and -k options work when pinging IPv4 addresses only. The -R and-S options only work with IPv6. Other less commonly used switches for the ping command exist including [-j host-list] and [-khost-list]. Tip: Save all that ping command output to a file using a redirection operator. The -noption tells the ping command to send 5 ICMP Echo Requests instead of the default of 4 and the -l option sets the packet size for each request to bytes instead of the default of 32 bytes.

Ping statistics for Using the ping command to ping The IPv6 version of this test would be ping Pinging J3RTY22 [ Also, as you can see, the -6option produced IPv6 addresses. You can generate a table of Zone IDs matched with your network interface names by executing netsh interface ipv6 show interface.

Server Fault is a question and answer site for system and network administrators. It only takes a minute to sign up. I am trying to write a script that lists all the hosts on my LAN there a about 20 of them and writes the ping status next to each host. Unfortunately, when a host is offline, the ping takes a long time to timeout. I checked man pingthere seem to be two options to set the timeout delay: -w deadline and -W timeout. I think I'm interested in the latter.

But waiting one second per offline host is still too long. I tried to set it to below a second, but it does not seem to take the parameter into account at all:. I accepted the fping solution thanks for all the other answers. This command does exactly what I was looking for:. This command takes at most ms to complete, and gives me the ping status of all the hosts at once:.

It does the same thing but uses layer 2 arp packets to do the 'ping'.

You can use a combination of arpping and icmp ping, or in fact tcp ping, to gather what the failure is. EXample is a tcp stack crash, although rare these days, we could find if a machine tcp stack had crashed, as the machine would not respond to ping, however it would respond to arp which is a different piece of code on the host.

If you have managed ethernet switches you can get physical link data, revealing if the machine is actually switched on, or had been physically unplugged. We had a situation where machines clients in public rooms would be switched off, we gathered that data and the sent wake on lan packets, to power up the machines.

What ever solutions you build, if your network is busy, think about implementiing some kind of qosso that your monitoring packets take priority on the network, losing measurement packets due to network congestion can give false alarms. If do use qos for monitoring packets, then you'll need to think about gathering data about network utilisation. So, you can make your monitoring solution as complex or as easy as you like.

We find even the most elementary monitoring system is a step in the right direction, at least some administrator is keeping any eye on machines It's a quick way to check if machine responds at all, assuming it'll respond in time less then specified amount of seconds.

If you can scan your subnet or part of it without triggering security alarms, and don't mind a bit of extra data, Angry IP Scanner is fast, free, lets you click to sort by status, and can provide more detailed information.

Why not launch ping in the background, with output to a temporary file, in parallel for every host? Then sleep for one second, kill any ping processes that are still running, and read the files to collect the output.

The timeout is an integer value indicating how far and long the packet can be sent. Values below 1 are meaningless. A value of 1 indicates you are pinging immediate neighbors only.This document illustrates the use of the ping and traceroute commands.

For all the options about this command, see "Ping" under Troubleshooting Commands. Here is an output example showing the ping command after enabling the debug ip packet detail command:.

This may result in a severe performance degradation or a network outage. We recommend that you carefully read Use the Debug Command before issuing debug commands. Here are examples of unsuccessful ping attempts, determining the problem, and what to do to resolve the problem. Since no routing protocols are running on Router1, it does not know where to send its packet and we get an "unroutable" message.

Router1 is correctly sending its packets to Router2, but Router2 doesn't know how to access address This is slightly better. Router1 is sending packets to Router4, but is not getting any answer from Router4.

Router4 receives the ICMP packets, and tries to answer to This is a situation where the interface stops working. In the example below, we try to ping Router4 from Router Since the routing is fine, we will do the troubleshooting step-by-step.

First, let us try to ping Router From the above, we see that the problem lies between Router2 and Router3. One possibility is that the serial interface on Router3 has been shut down:.See the ping definition for a full description.

The command above does not send information over the network, but can indicate if the card can respond. Ping supports the ability to ping an Internet address. In the example above, we pinged "computerhope. If we couldn't reach the server or the server was blocking our request, we would have lost all four packets. If you do not get a reply, or get lost packets, you have a problem with your network, which is a cable issues, network card issues, driversrouterswitchor other network problems.

To get the IPv4 IP address, use the following command. The hostname can be any computer and the -4 forces the address to be shown as an IPv4 address. Availability Ping syntax Ping examples Related questions. Windows Vista, 7, and 8 syntaxes.

You can save the ping command output to a file using a redirection operator. In this example, the ping command is used to ping the hostname www. The -n option tells the ping command to send 5 ICMP Echo Requests instead of the default of 4, and the -l option sets the packet size for each request to bytes instead of the default of 32 bytes. This means that, as far as this network connection goes, it can communicate with Google's website just fine.

In the above example, we're pinging Using the ping command to ping The IPv6 version of this test would be ping In this example, we're asking the ping command to find the hostname assigned to the The command might resolve the IP address, Similar to the ping command examples above, this one is used to see if your computer can reach your router.
