How to ping sweep a subnet?

There’s a lot of ways to ping the whole subnet or do a sweep ping to the whole network, of course download any free software that can do this, or just manually ping the whole network by manually changing the IP address.

Or do an old school method, using a batch file. This link shows how to ping the whole subnet via command line.

Since PowerShell is readily available from Windows 7 up to the newer versions of Windows. Then PowerShell is the perfect choice to do this task.

Open PowerShell ISE or the PowerShell command line, then type or copy the commands below:

$ping = New-Object System.Net.Networkinformation.Ping
1..254 | % { $ping.send(“192.168.1.$_”) | select address, status | ft -auto }

Change the IP Address (192.168.X.X) to the IP address range of your network.

What the script does, is to Ping the whole network starting from 1 to 254, basically the whole network host address range. The output will be filtered to show only the IP Address and the Status of that address.

Sample output:

Address                           Status
-------                           ------                      Success DestinationHostUnreachable                      Success                      Success DestinationHostUnreachable DestinationHostUnreachable                      Success

Basically, if it shows success then the host or the IP Address is in use, other than the it means that the device is offline or the IP Address is not assign to any device.

That’s it a simple code, and you can use it to check your network which IP Address is being used or whether the device assign with a specific IP Address is online or not.

Of course, the script is useful provided that the computer, server or the network device is configured to response ICMP request or ping request. If the device is not configured to response to a Ping request then I guess other methods can be used or manually checking whether computer is online or not.

There’s always a trade-off, security paranoia or enabling settings that make life easier.

Till next time. Cheers!

Copy a single file using robocopy

Copy a single file using robocopy from a local folder to a shared folder on the network.
A simple rule of thumb before any disaster strike, don't interchange the source and the destination.

If source and destination is mistakenly reverse, files might get overwritten. To avoid any loss of data do a test with a dummy file to ensure things work perfectly.
Robocopy [source][destination]   [file to be copied]
robocopy c:\local_c_folder  \\PC_network\shared_folder   file_to_be_copied_xx.txt
The command will be completed successfully provided the network access right has no issues.

Robocopy works quite good on large files. A simple copy or xcopy command will also work but the speed might vary.

Robocopy is free it can be accessed from command line. No need to install the resource kit tool if the operating system is Windows 7 or newer version.

Copy files with selected file extension using PowerShell and Robocopy:

$extension = ('.pdf', '.jpg', '.txt')
gci d:\WorkFolde…

WMIC get computer name

WMIC get computer model, manufacturer, computer name and  username.
WMIC is a command-line tool and that can generate information about computer model, its manufacturer, its username and other informations depending on the parameters provided.
Why would you need a command line tool if there’s a GUI to check?
If you have 20 or 100 computers, or even more. It’s quite a big task just checking the GUI to check the computer model and username.
If you have remote computers, you need to delegate someone in the remote office or location to check.
Or you can just write a batch file or script to automate the task.
Here’s the code below on how get computer model, manufacturer and the username.
Open an elevated command prompt and type:
wmic computersystem get "Model","Manufacturer", "Name", "UserName"
Just copy and paste the code above, the word “computersystem” does not need to be change to a computer name.
