USB to Ethernet NICs

**peanut99** · August 31st, 2013

Hi All. I'm studying for my CCIE and decided to use Ubuntu over Windows for various reasons. I purchased multiple USB-to-ethernet NICs (JP1082 NO: 030818) and when I plug them in together, I have some weird issues. All of the USB to Ethernet NICs seem to receive the same mac-address. When I plug them into a Windows box, they all receive different mac addresses. Also, only the first USB-to-Ethernet adapter will receive a standard "eth#" name and the rest are named "rename#". Anytime I reboot, the "rename#" will change. Is there a way to permanently change the name of each USB to Ethernet NIC to a standard "eth#"? Also, is there a reason that all of my NICs get the same mac address? I've attached a screen shot of my issue. Notice eth3's mac address is the same as the "rename#" mac address. I'm using Ubuntu 12.04. Any assistance is greatly appreciated. Thanks!

Hay,

After you plugged them in, please supply the output of the following for more information on what ubuntu is doing:

Code:

lsusb -v
lsusb -t
lsmod
dmesg | tail -n 100

This should show us how ubuntu is addressing the devices and where the issue might sneak in.

Cheers

Let me know if you need any additional output. Thanks!

Hay,

Yea just as I expected, it is a driver issue. I'll look around on how to fix that just now.

First, try and shift one of the two (from the output I only see 2 additional controlers?) controlers to another USB port (Move it to a USB 3 port just to be sure it gets moved off of the same root hub).

See if this fixes the issue, also why do you need 3 ethernet interfaces?

If the above does not solve the issue you can start by:

Code:

#Make a backup of the file:
cp /etc/udev/rules.d/70-persistent-net.rules ~/70-persistent-net.rules.bak
#Open file as sudo for editing
sudo nano /etc/udev/rules.d/70-persistent-net.rules

Now in there you can rename the devices as you wish. Also please post the output of:

Code:

cat /etc/udev/rules.d/70-persistent-net.rules

I have no idea why your 2 devices has the same MAC address. I think this is because the driver is loaded only once:

dm9601 13579 0
usbnet 26212 1 dm9601

It is hard for me to explain in detail what to edit since I can by no means duplicate your set up. But I will try my best if you supply the file above and have already tried changing the names appropriately.

Cheers and good luck

Thanks again for the assistance. I actually need 12 of these USB to ethernet adapters to bridge my physical hardware (Cisco Switches) into GNS3. I'll mess around with the file you mentioned. Here's the output:

Hay,

I see all different mac's in that post. Maybe you can try this to change the macs if it gives issues (as in the original post's screenshot)

http://www.ubuntugeek.com/macchanger...i-utility.html

Hmm interesting concept on bridging them all (12 over USB? wow)

I wish I could duplicate the setup to give more clean cut answers.

**houstonbofh** · September 1st, 2013

USB makes all of this much more complex than it needs to be, especially with 12 of them. The thing is Ubuntu can never know which one will "answer first" and so the order is based on mac address... If that fails, everything behind it fails. I would consider trying with some Intel dual port pci-e nics. They go for $20 on eBay.
