Changing the name of a network card

[Scormen]

Hi all,

I have 3 network cards in my computer (a server for dhcp, firewall, network bonding, etc - 1 NIC is on the motherbord, the other 2 are PCI's). How can I know what card is eth0, eth1 or eth2?

With a brand new installation with Ubuntu 8.04 (server edition) I'm having also a strange problem. After the installation, the names of my network cards are "eth0", "eth1" and "eth1_rename". Is there a way to rename that card with name "eth1_rename"?

Thanks,
Kris

This will tell you about your network cards:


sudo lshw -C network

I'm not sure if you can rename what the logical name of a NIC is, however it is theoretically possible.
I found a link on google you might find useful:

Hi!

Thanks for your answer.

I know lshw, but how do I now what "physical id" is the real peace of hardware in my server?

I'll gonna have a greater look at that document of your link, but the pahts for the program files are different, that file is quite not for Ubuntu/Debian ;)

Someone else maybe?

Thanks again,
Kris

Hi all,

I have found this howto: How to change network interface names in Ubuntu (click) (http://www.jusupov.com/2008/07/23/how-to-change-network-interface-names-in-ubuntu/)

In the file /etc/network/if-post-down.d/ifenslave I have this:

# PCI device 0x10ec:0x8169 (r8169)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:17:3f:9a:00:0e", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

# PCI device 0x10ec:0x8169 (r8169)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:17:3f:9a:00:0e", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"

# PCI device 0x10ec:0x8139 (8139too)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:10:dc:2d:9c:e7", ATTR{type}=="1", KERNEL=="eth*", NAME="eth2"

# PCI device 0x10ec:0x8169 (r8169)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:17:3f:9b:f2:e9", ATTR{type}=="1", KERNEL=="eth*", NAME="eth3"

Now, the name of the last interface is "eth3". When I restart the server the name is "eth1_rename". When I restart again, it is again "eth3", and so on...

I am using network bonding with ifenslave (packages.ubuntu.com/nl/hardy/ifenslave-2.6) (info here (http://www.linuxhorizon.ro/bonding.html)) because it is a bussy line...

"eth0" and "eth3" are bonded to "bond0". Here is my /etc/network/interfaces:

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth2
iface eth2 inet static
address 10.10.10.31
gateway 10.10.10.4
netmask 255.255.255.192

auto bond0
iface bond0 inet static
address 192.168.1.1
netmask 255.255.255.0
post-up ifenslave bond0 eth0 eth3


Here is my lshw -C Network:

Does anybody have a idea or a solution?

Many thanks,
