Show interfaces via command line




Using netsh.exe will list network interfaces that are connected to the windows machine.

netsh interface ipv4 show interfaces
netsh interface ipv6 show interfaces

If the device is connected or disconnected the command line output will show the state of the interface.

But if the network interface device is disabled the interface will not be included on the output list.

Sample output of the command:

netsh interface ipv4 show interfaces

Idx     Met         MTU          State                Name
---  ----------  ----------  ------------  ---------------------------
  1          50  4294967295  connected     Loopback Pseudo-Interface 1
 12          10        1500  disconnected  Local
 23          20        1500  connected     VirtualBox Host-Only Network
 16          20        1500  connected     VMware Network Adapter VMnet1


Route print command in windows is quite handy also to check the gateway, the mac address of the interface and also the IP Address.

Sample output:
c:\Windows\System32>route print
===========================================================================
Interface List
 12...mac Address like: 00 bc ad 77 88 ......Intel(R) 82579LM Gigabit Network Connection
 17...mac Address ......VMware Virtual Ethernet Adapter for VMnet8
  1...........................Software Loopback Interface 1
===========================================================================
IPv4 Route Table
===========================================================================
Active Routes:
Network Destination        Netmask          Gateway       Interface  Metric
          0.0.0.0          0.0.0.0  192.168.19.254   192.168.19.50     10


In Linux world, "ifconfig -a" or "ip addr show" will also give the list of interfaces and the interface state whether down or up.

ifconfig -a and ip addr show will include both IPV4 and IPV6 addresses.

"route -n" will show whether gateway is configured on the Linux box.

If the gateway is not configured, then the Linux box or either a Windows box will not be able to connect to the internet.

If the computer or server is behind a firewall and everything is configured properly Gateway, IP Address and DNS settings are set but no internet connection check the router or firewall if NAT translation is enabled or a Public IP (such as 1 to 1 mapping of IP Address) is needed to connect to the internet.

On a Cisco router, NAT translation has to be enabled on the router for the private IPs to be able to connect to the internet. If the device or a machine is behind a firewall, such as Juniper firewall NAT translation and a policy has to be define.

If the machine is on DMZ mapping of NAT'ed IPs to  Public IP has to be configured for the  device on the DMZ to be able to communicate with the internet.


Cheers!!1 Hope it helps and give some ideas...

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.

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. ...
