Cmd For Mac

Posted on

To use a keyboard shortcut, press and hold one or more modifier keys and then press the last key of the shortcut. For example, to use Command-C (copy), press and hold the Command key, then the C key, then release both keys. Mac menus and keyboards often use symbols for certain keys, including modifier keys:


On keyboards made for Windows PCs, use the Alt key instead of Option, and the Windows logo key instead of Command.

  1. Hold down the “ Windows Key ” and press “ R “. Type “ cmd “, then press “ Enter “. Type “ ipconfig /all ” and press “ Enter “. The “ Physical Address ” is listed, that is the MAC Address of your network card.
  2. The MAC address is used by the network hardware such as routers, switches, etc. To send traffic from one device to another device on your network. Your computer uses a service called ARP (Address Resolution Protocol) to resolve and track the TCP/IP and MAC address of the remote devices that you're communicating with.
  3. This can be used to get mac address for remote computers also. Below are few examples on how to use this command. It works on XP, Vista, Windows 7, Server 2003 and Server 2008 operating systems. Get mac addresses from CMD. Just run the command getmac to get the mac addresses. Find an example below.

First, run the command prompt. Click on the Start button. Type 'cmd' without the quotation marks in the text box and then press Enter. This will open the DOS Command Prompt window. An alternative way to get to the command prompt is to click on Start, go to the Accessories folder and click on Command Prompt. Next, run the command. The command may work if the device utilizes NetBIOS over TCP/IP. I.e., you will likely see the MAC address in the output if the system uses that networking protocol, but, if it doesn't, which is likely if the system is a printer, then relying on nbtstat -a ipaddress to obtain the MAC address is not the best way to obtain that address. A command line prompt is a way of interacting with your computer without a graphical interface. While your modern Mac uses a graphical user interface, (GUI) older computers used only command prompts. The command line usually gives you more options than the GUI. A command line prompt is a way of interacting with your computer without a graphical interface.

Some keys on some Apple keyboards have special symbols and functions, such as for display brightness , keyboard brightness , Mission Control, and more. If these functions aren't available on your keyboard, you might be able to reproduce some of them by creating your own keyboard shortcuts. To use these keys as F1, F2, F3, or other standard function keys, combine them with the Fn key.

How to find an IP address when you have the MAC address of the device.

4 Steps total

Step 1: Open the command prompt

Click the Windows 'Start' button and select 'Run.' In the textbox, type 'cmd' and click the 'Ok' button. This opens a DOS prompt.

Step 2: Familiarize yourself with arp

Type 'arp' in the command prompt. This gives you a list of options to use with the arp command.

Step 3: List all MAC addresses

Type 'arp -a' in the command prompt. This lists a number of MAC addresses with the associated IP addresses. Since you have the MAC address, scroll down the list to find the associated IP address. The MAC address is shown in the 'Physical Address' column with the IP address in the 'Internet Address' column. An example of a table record is in Step 4.

Step 4: Evaluate results

The following is an example of ARP output. The first column is the IP address. The second column is the MAC address, and the third is the type of IP assigned--static or dynamic.

Internet address Physical Address Type

    You've forgotten about one little thing: arp keeps mac<>ip association of recently contacted peers, so it's quite often not to find the mac<>ip association we're looking for, of machine that exists in the network. Prior to using arp -a it's wise to ping the host first.

    I thought the aim of this exercise was to FIND an IP address. Doesn't using PING imply you already know the IP (or hostname) which makes ARP redundant? How do you PING a MAC?

    Assuming no IP or hostname info, I have used a portscanner (like LanSpy or Zenmap) to get MAC > IP info. Currently my preferred method if the device isn't listed in Spiceworks :-)

    There was a time when I was a baby admin and I didn't want to raise alarms by installing a scanner that I wrote a batch file (yes, that long ago) that PINGed every IP on a subnet, then immediately ran ARP redirecting output to a text file. But that depends on the device in question being set to respond to PING requests.

    This does not work for any host on the other side of a router. Any hosts on the other side of the router will show the routers MAC address.

    I realize this is an old topic, but someone like myself may be looking for an answer. I became admin of a network with little over 200 devices, which none of the cabling was mapped. I was told I was responsible for the cabling, so I began looking for a way other than toning out all the cables. I was fortunate to have Cisco switches and Windows Server 2008. I was able to use the Cisco Network Assistant to grab MAC addresses and the port number, then in DHCP on the Server 2008 I could find the MAC and corresponding IP. Furthermore I could also get the computer name from DHCP and correlate that to which user was on the machine using PDQ inventory to see who was logged in to the machine. Most of this of course depends on the devices being in use. I've been able to create an accurate map of about 90% of my network without touching the cables.

    I am interested in this thread, hopefully someone can help. There are 4 types of arp message: arp request, arp reply, rarp request, rarp reply. So, that being said, is it possible to manually send a rarp request? Sort of a arp based ping?There is arping, but we need rarping.. if it exists. Of course, I understand that I can't arp outside my default gateway, but if there is a rarp request, how is it used inside the local network? Thanks to whatever guru can explain what we're missing.

    Great for finding an IP if you have the MAC address.

    My instance where I found this useful was after updating the firmware on a switch remotely via TFTP, the IP of the switch would change (making pinging redundant, obviously). Trying a network scan over Spiceworks or rescanning the single device would not update the IP and I needed an alternate way to find it.

    This method worked perfectly. Thank you. Hopefully this helps those trying to understand the purpose of this practice and how it was in-fact useful.

    I understand the issues in attempting to use a MAC address to locate a device from outside of its local network.
    What puzzles me is how Honeywell Total Connect does this with their WiFi connected thermostats. The hardware configuration is: a Honeywell WiFi thermostat that is WiFi connected to a Netgear N600 router which uses DHCP to assign an IP adddress. The router is connected to Comcast with a Motorola SB6120 modem. Comcast assigns a system wide (dynamic) IP. There is no static IP.
    On initial setup, a WiFi connection is first established between the thermostat and the router. The thermostat's MAC and CRC and a username and password are entered into the Total Connect software setup. It is then possible to read or set thermostat values using Total Connect Web pages.
    I know how to do this with a static IP or a DNS service that automatically tracks changes in dynamic IP addresses.
    Does anyone understand how this works with Total Connect?

    This post was extremely helpful, thanks itdownsouth :) I used show interface to find MAC addresses on our switches (reason for this is poor network documentation and mis-labeled switchports and wall jacks..). I took the MAC addresses that I could not locate the hosts or ip addresses for, ran arp -a to list the address<>mac list, then one by one, nbtstat -A for each IP address I matched a MAC to from the unlabeled ports. Tedious, but found 5 or 6 now (seeing hexadecimal thoughts now though..).

    By the way, the reason this is working great for me is the lack of routers -- all switches, so if you have only one subnet like we do, this will do -- otherwise, you will probably need to login to the router or switch on the other side of the router to find MAC address tables on the other networks. You may not be able to see them all on the local host, as far as arp -a on the local host, but looking up the arp or hosts tables on switches and routers could be a possible solution for those with multiple subnets.

    Use SuperScan to do a bulk ping of the entire network range. SuperScan 3 (I recommend) is a free tool by McAfee.

    Then use arp -a Find '5c-d9-98' to get for example all ping nodes with a manufacturer of Asus.

    There's also this:

    http://www.advanced-ip-scanner.com/

    It should be able to find most devices on the network. You can specify the range to scan and scan across subnets. I won't try to share all the features because quite frankly I don't know them all.

    @RobertRobinson I'm the lead designer and project manager on the Honeywell systems.

    I can tell you exactly how I designed it. It's actually quite simple. Nothing is sent back to the unit. The unit is allowed access to the Internet via your setup and the router. As long as the unit has permission to make an outbound connection it will work. What happens is the unit makes a report to the server. If it needs to make a request then it gives the server a unique key. The server puts any needed data in an xml (readable) and the thermostat (or quite a few other devices) hits that URL a few seconds later (the device told the server where it would pick up that info).

    All your device needs is a simple read-only connection to the outside world. No need to download anything.
    It's a VERY simple process that I developed back in 1992 when the Interwebs were still pretty new to most people. There were many processes built off of this simple idea (it was pretty cutting edge when I first designed it). Store and forward, offline browsing, push technology, etc. all are based on this simple technology.

    Am I rich? Not even close. I was working on my PhD at the time and was hired by Honeywell to implement my design. I literally gave it away to the general public as is right.

    I hope that clears it up for you. If not, feel free to contact me for more information.
