I'm still struggling to discover my MAC address under Linux. If all else fails, you can always get Magma to tell you the MAC address. Of course, if you have a local sysadmin they can probably determine this information for you. If that does not work, it is possible that the output from running dmesg will include the MAC address (amongst a lot of other information). The XX:XX:XX:XX:XX:XX part from the above is the MAC ing some other operating system?įor UNIX systems, try running ifconfig as described in the Linux instructions.

(Note: some fields may have only one digit in them. The relevant line(s) will look like this: foo (xx.xx.xx.xx) at XX:XX:XX:XX:XX:XX permanent published where each X is a hexadecimal digit ( 0 to 9 or A to F). Type the following command: arp `hostname` This command will print address resolution information for the machine. If your machine's network interface is currently up (i.e., it is connected to a network) you may be able to use arp instead. This is OK.)Unfortunately, the previous approach does not work without superuser access (all information except the MAC address is displayed in that case). The relevant line(s) will look like this: ether XX:XX:XX:XX:XX:XX where each X is a hexadecimal digit ( 0 to 9 or A to F). If you have superuser access to the machine, run su to become the superuser and type the following command: /usr/sbin/ifconfig -a This will print information on all networks in the system. To determine the MAC address of a machine running Solaris, begin by creating a shell or terminal window, if you do not already have one. The XX:XX:XX:XX:XX:XX part from the above is the MAC ing Solaris? The relevant line(s) will look like this: eth0 Link encap:Ethernet HWaddr XX:XX:XX:XX:XX:XX where each X is a hexadecimal digit ( 0 to 9 or A to F). In the shell, type the following: /sbin/ifconfig -a This command will print information on all networks in the system. The other likely location is in the Applications menu, possibly in the System Tools submenu. If using a desktop environment such as Gnome or KDE, this can usually be found as an option in the right mouse button menu (common choices of name are “Terminal”, “Konsole”, or “Shell”). To determine the MAC address of a machine running Linux, begin by creating a shell or terminal window, if you do not already have one. The XX:XX:XX:XX:XX:XX part from the above is the MAC ing Linux? To determine the MAC address of a machine running Windows Vista or Windows 7, click on the Start menu, type “cmd.exe” in the “Search programs and files” box, and press Enter. How do I determine my MAC ing Windows Vista or Windows 7?

The MAC address is used to generate the magmapassfile, so that Magma will run on the appropriate machine.

A MAC address consists of 48 bits, usually represented as a string of 12 hexadecimal digits ( 0 to 9, a to f, or A to F) these are often grouped into pairs separated by colons or dashes. It is an abbreviation of “Media Access Control” and is supported by all modern computer hardware.Ī MAC address is an essentially unique number associated with a network card in a machine it serves as a convenient way to distinguish between two different computers. What should I do?įirst note that a MAC address has nothing to do with Mac OS X or Macintosh computers.

I replaced or upgraded my hardware, and now my MAC address is different.
