Enable ICMP or Ping request on Windows


If you ping a remote computer but fails, it could be that the firewall does not allow ICMP protocol.

Enabling ICMP or ping requests is quite useful for troubleshooting purposes but it could be also a security issue.

To enable ping or ICMP in Windows Firewall with Advance security, can be done via command line or using the graphical interface.

Command line is quite useful if the setting has to be done repeatedly or it has to be done on multiple machines.

Command line will also be helpful if a setting has to be enabled or disabled at times. Graphical interface is of course the easiest method if it has to be done one time but if the setting has to be done a couple of times then command line or scripting is definitely a good choice unless the person loves to click and click.

Enable Ping response using command line:
netsh advfirewall firewall add rule name="ICMP Allow incoming V4 echo request" protocol=icmpv4:8,any dir=in action=allow

Disable Ping response using command line:
netsh advfirewall firewall add rule name="ICMP Allow incoming V4 echo request" protocol=icmpv4:8,any dir=in action=block

If ping or icmp echo request is disable on the firewall and some program or any icmp or ping request to a specific device will always show "Request time out" as a response to the ping request.

If ping or icmp echo request is allowed or not block, then the device will response depending on its current state. For example, if the device is online then it will response or reply to the ping request.

Commands above should be run at an elevated command prompt.

The command prompt will show a message like: The requested operation requires elevation (Run as administrator).



Cheers..Till next time..

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.

Notepad++ convert multiple lines to a single line and vice versa

If the data is in a “.csv” format or comma separated values which is basically just a text file that can either be opened using a text editor, excel or even word. Notepad++ can process the contents of the file using regex. Example if the data has multiple rows or lines, and what is needed is to convert the whole lines of data into a single line. Notepad++ can easily do it using regex. However, if the data is on a single line and it needs to be converted into multiple lines or rows then regex can also be used for this case. Here’s an example on how to convert multiple rows or lines into a single line. Example data: Multiple rows, just a sample data.

Print error 016-799 - Fuji Film Xerox

016-799 Fuji Xerox or Fuji Film print error code. That shows a description error as “Print instruction Fail detected in decomposer.” The error code and error description are alien languages for users and even system administrators who are not familiar with Fuji Xerox error code. The error code is quite simple and easy to fix, if the job print goes to the printer but print out doesn’t come out. So, basically the print job was received by the printer, but the printer just doesn’t know what type of paper or what size to use or which tray to utilize for the print out. In some instances, this is just a paper mismatch but the error description; if using Windows 10 to print does not exactly points to what is the issue. First thing to check, is the paper size selected by the user to print. Example, if the printer configuration is A3 and A4 sizes only. But then the person printing the file accidentally chooses “A4 Cover” then this error 016-799 will occur. ...
