Description Bob Goodwin 2012-12-18 19:52:09 EST
Description of problem:
'udev' does not create an entry in /dev for my builtin motherboard ethernet device (em1).

The device is working correctly. 'ifconfig' command shows the device is up and running. QEMU allows full web browsing through this device (does not require a native /dev entry). Native linux internet apps won't run. I believe that this is because there is no /dev/em1 configuration. 

Version-Release number of selected component (if applicable):

How reproducible:
permanent condition. Internet apps cannot access the internet.

Steps to Reproduce:
1. unknown
Actual results:
Native Linux apps are unable to access the internet. Typical apps are Firefox, yum, date/time update, weather update, Lynx. 

There is no device configuration provided in the /dev/ directory.

Expected results:
'udev' needs to create a /dev/em1 (or other appropriate name) entry for this device.

Additional info:

Everything was working up until 12/15/12. Around that time, I received a fairly large list of software updates. I also used the GNOME 'firewall' gui app to enable samba.

According to the system log file, the kernel originally configures this device as 'eth0'. The device name is modified by biosdevname to 'em1'.

I am unable to find appropriate major/minor number info in any documentation online or I would create the /dev entry myself.

Hmm.. Linux does not have device nodes for network interfaces. I am sorry. :-)
