Find/Display your MAC Address Linux/UNIX

How to find/display your MAC Address:Unix/Linux


Linux

  • As the root user (or user with appropriate permissions)
  • Type "ifconfig -a"
  • From the displayed information, find eth0 (this is the default first Ethernet adapter)
  • Locate the number next to the HWaddr. This is your MAC address
The MAC Address will be displayed in the form of00:08:C7:1B:8C:02.
Example "ifconfig -a" output:
eth0      Link encap:Ethernet HWaddr 00:08:C7:1B:8C:02
          inet addr:192.168.111.20  Bcast:192.168.111.255  Mask:255.255.255.0

...additional output removed...

Solaris/SunOS

  • As the root user (or user with appropriate permissions)
  • Type "/sbin/ifconfig -a"
  • From the displayed information, find the Ethernet adapter (it will probably be called le0 or ie0)
  • Locate the number next to ether. This is your MAC address
The MAC Address will be displayed in the form of 0:3:ba:26:1:b0-- leading zeros are removed. For this example, the actual MAC Address would be 00:03:ba:26:01:b0.
Example "ifconfig -a" output:
le0: flags=863 mtu 1500
     inet 192.168.111.30 netmask ffffff00 broadcast 192.168.111.255
     ether 0:3:ba:26:1:b0

FreeBSD/NetBSD

  • As the root user (or user with appropriate permissions)
  • Type "ifconfig -a"
  • From the displayed information, find the Ethernet adapter (the name changes based on the Ethernet card installed)
  • Locate the number next to the HWaddr. This is your MAC address
The MAC Address will be displayed in the form of00:08:C7:1B:8C:02.
(Using the command"dmesg"will also display the MAC address -- along with a lot of other information)
Example "ifconfig -a" output:
    ed0: flags=8843 mtu 1500
         inet 192.168.111.40 netmask 0xffffff00 broadcast 192.168.111.255
         ether 00:08:C7:1B:8C:02

OpenBSD

  • As the root user (or user with appropriate permissions)
  • Type "netstat -in"
  • From the displayed information, find the Ethernet adapter (the name changes based on the Ethernet card installed)
  • Locate the number below Address. This is your MAC address
The MAC Address will be displayed in the form of00:08:c7:1b:8c:02.
Example "netstat -in" output:
Name  Mtu  Network  Address           Ipkts    Ierrs Opkts   Oerrs Colls
fxp0  1500 <Link>   00:08:c7:1b:8c:02 4112773  0     224501  0     0

Caldera/SCO UnixWare/OpenUNIX

  • As the root user (or user with appropriate permissions)
  • Type "ndstat"
  • From the displayed information, find net0 (this is the default first Ethernet adapter)
  • Locate the number below MAC Address in use. This is your MAC address
The MAC Address will be displayed in the form of00:00:c0:88:0a:2e.
Example "ndstat" output:
   Device       MAC address in use    Factory MAC Address
   ------       ------------------    -------------------
   /dev/net0    00:00:c0:88:0a:2e     00:00:c0:88:0a:2e

HP-UX (HP UNIX)

  • As the root user (or user with appropriate permissions)
  • Type "/usr/sbin/lanscan"
  • From the displayed information, find lan0 (this is the default first Ethernet adapter)
  • Locate the number below Address. This is your MAC address
The MAC Address will be displayed in the form of0x000E7F0D81D6 -- the leading hexadecimal indicator should be removed. For this example, the actual MAC Address would be00:0E:7F:0D:81:D6.
Example "lanscan" output:
Hardware Station        Dev Hardware Net-Interface   NM  Encapsulation      Mjr
Path     Address        lu  State    NameUnit State  ID  Methods            Num

Interpreting the output of lspci

On Linux, the lspci command lists all PCI devices connected to a host (a computer). Modern computers and PCI devices communicate with each other via PCI Express buses instead of the older Conventional PCI and PCI-X buses since the former buses offer many advantages such as higher throughput rates, smaller physical footprint and native hot plugging functionality. The high performance of the PCI Express bus has also led it to take over the role of other buses such as AGP ; it is also expected that SATA buses too will be replaced by PCI Express buses in the future as solid-state drives become faster and therefore demand higher throughputs from the bus they are attached to (see this article for more on this topic). As a first step, open a terminal and run lspci without any flags (note: lspci may show more information if executed with root privileges): lspci   This is the output I get on my laptop: 00:00.0 Host bridge: Intel Corporation Haswell-ULT DRA...

How to Remove a Storage Device (LUN)

Before removing access to the storage device itself, it is advisable to back up data from the device first. Afterwards, flush I/O and remove all operating system references to the device. Stop all access to the device that has to be removed. Unmount the device. Remove the device from any md and LVM volume that is using it. If a multipath device is being removed, run  multipath -l  and take note of all the paths to the device. When this has been done, remove the multipath device: # multipath -f device   Use the following command to flush any outstanding I/O to all paths to the device: # blockdev –flushbufs device   Remove any reference to the device's path-based name, like  /dev/sd  or  /dev/disk/by-path  or the major:minor number, in applications, scripts, or utilities on the system. This is important to ensure that a different device, when added in the future, will not be mistaken for the current device. The fi...
