List all IP Addresses of a server




Multi-homed server, a server with multi-services and is set with different IPs is quite common if there is a budget constraint. It is always good to have a dedicated server do a single function provided there is enough luxury to do it.

So if you just inherited the network and all the servers in your environment have documentation which is poor to nothing, then pray hard that nothing will happen until you have it under control by proper documentation and familiarization.

It's quite tough to troubleshoot when a problem arises if no proper documentation to depend on and there will be a lot of surprises as the work journey goes on.

Listing or getting the IP Addresses on your entire server and having a proper documentation will definitely help and ease the tension during some issues.

It’s also easy to troubleshoot during a network outage or other circumstances that may arise.

Listing the IP Address of a server can be done in different ways.

Doing it remotely is quite convenient and of course with the help of PowerShell that makes life easier for Sys Ads.

PowerShell script below will get or list the IP Addresses configured on a server.

To use the script, the input parameter can either be a hostname or a single IP Address on the server.

If you only know a single IP Address configured on the server but don't know the hostname or other IP Addresses set on the server, the script below just need one IP and will list other IPs set on the server.

Here's the script:

#$ip - can either be hostname or IP Address

#$ip="192.168.100.1"

$ip="D_Free_Server"

$result = [System.Net.Dns]::gethostentry($ip) | Foreach-Object { write-host $_.AddressList }

Run the script on PowerShell ISE to test, if the queried IP Address or hostname has multiple IP addresses set on the NICs all IPs will be displayed.

Script above can also be written like this script below:

#$ip - can either be hostname or IP Address

#$ip="192.168.100.1"

$ip="D_Free_Server"

$result = [System.Net.Dns]::gethostentry($ip) |select-Object { $_.AddressList }

$result

The issue with the above script the result is truncated and ellipsis is shown, therefore the data is incomplete.

As a workaround for this scenario, use write-host as used on the first script above.

Example script above can also get the hostname by querying the IP Address of the server.

Here's the PowerShell script:

$ip="192.168.100.1"

$result = [System.Net.Dns]::gethostentry($ip) |select-Object { $_.HostName }

$result  #<

PowerShell script above gets the hostname of the server by querying the IP Address.

That's it guys till next time.

Hope the example above will boil your motivation to get your hands wet to learn PowerShell.

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

Notepad++ is an awesome text editing tool, it can accept regex to process the text data. 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. Press Ctrl+H, and  on "Find what" type: [\r\n]+ and on "Replace with" type with: , (white space) --white space is needed if need to have a space in between the data. See image below, "Regular Expression" must be se...

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. ...
