As far as I can see, it supports no method of actually asking "what is your PROM ethernet address" - the MAC address is read out during the "probe1" section of the module initialization, and stored away.
HOW TO FIND MAC ADDRESS IN LINUX DRIVERS
I had a quick look at the pcnet32.c drivers (because it's one of the models of network card that I have a rough idea how it works and where the different registers are, etc, so I can see what it does).
HOW TO FIND MAC ADDRESS IN LINUX SOFTWARE
Of course, there are cases where there isn't a hardware network card for that particular interface - virtual network drivers for virtualization and when using bridges and software switches for example.Īnd of course, the hardware may be such that you can't actually read the "original" MAC address when it has been overwritten by software, because there is only one set of registers for the MAC address itself. In addition to the virtual IP address, each interface is also associated with a hardware MAC address that it can be necessary to know.
HOW TO FIND MAC ADDRESS IN LINUX DRIVER
The only way to find the original MAC address is to use the same method the network card driver does - unfortunately, I don't believe there is a generic way to tell the driver to provide it's MAC address "as provided by the hardware". Finding the MAC Address of the Linux Box. Memcpy(mac, ifr.ifr_hwaddr.sa_data, IFHWADDRLEN) #include /* for the glibc version number */ ** below code gives my current MAC but not original MAC #include /* Standard I/O */
HOW TO FIND MAC ADDRESS IN LINUX HOW TO
but don't know how to do this in above case. Is there any utility for it or command for it? how do I find the original? There must be a way to find it, because it is still burned permanently into the card, but I can't find a tool to read the burned in address. 'ifconfig eth0 hw ether uu:vv:ww:yy:xx:zz',or I set "permanent" it using vi /etc/sysconfig/network-scripts/ifcfg-eth0.this file.I can successfully UP it in REBOOT also. I understand how to find the current MAC address using ifconfig, but if the address has been changed, say by using I'm trying to figure out how to find the original MAC address of an ethernet NIC on my linux box. Is this possible to read MAC address form NIC directly ? I have below code but it just read from above layer but not the card itself !!! Click the Windows Start button and select Run. The IP command is very strong and powerful.Os:REDHAT LINUX Linux manage: 2.6.18.8-1 # How can I find the IP address from a MAC address How to find an IP address when you have the MAC address of the device. The IP command replaces the ifconfig command, which is part of the net-tools package. This command will work on different Linux systems, such as Kali Linux, Arch Linux, Fedora, Ubuntu, etc.

The network parameters of Linux are useful to withdraw by using this command. Here, we will discuss the networking command IP in Linux. With the help of the IP command, you can find both the IP and MAC address of your network connection. Finding IP and MAC Address Using the Command-Line Next, we will show you how to find the IP and MAC addresses of a device with the help of the command-line in Linux. In the DLC layer, the other sublayer is a logical link control sublayer. For each type of device, there is a different MAC sublayer. In telecommunication protocols, the media access control, which is the sublayer of the data-link layer, uses the MAC address. The MAC address is the same as the Ethernet address on the Ethernet LAN.

When you are connected to the Internet as a host or your computer is connected to the Internet, the IP address of your computer is linked to the physical MAC address of the computer on a LAN. The MAC address, also known as Media Access Control address, is a unique and separate hardware number of a particular computer, especially in a LAN (Local area network) or in other networks.
