Hello,
My name is Manfred. I have to install a flexlm license server on a pc with centos 6.3 as operating system. This machine contains two network cards. An Ethernet card and a wifi card. For the Ethernet card centos generates a device called p3p2. For the wifi card centos generates a device called wlan0.
In this configuration the flexlm license program called lmgrd only got the mac address of wlan0. The vendor daemon got no mac address as host ID.
Yesterday I made one test. Therefore I edited /etc/udev/rules.d/70-peristant-net.rules. This file contains only one line. This line defines how to name the device for the wifi card. I changed the name Option from name="wlan0" to name="eth0". After rebooting centos generates a device called /dev/et0. Both lmgrd and vendor daemon found the host ID. But lmgrd and safetech can't communicate together.
As next I will try to rename /dev/p3p2 which is the device for the Ethernet card. I guess, if I can generate a device called /dev/eth0 for the Ethernet card the license server should work. But in /etc/udev/rules.d/70-persitant-net.rules is no rule for this device.
How can I configure centos to generate /dev/eth0 for the Ethernet card?
Mit freundlichen Grüßen / Best Regards / Cordialement,
Manfred

Check for a typo where you got the 'et0', that's not a normal name (emX, ethX, pXpY and wlanX are the usual).
As for a general comment/guide; make sure you've updated the /etc/sysconfig/network-scripts/ifcfg-X files (note the DEVICE="..." and HWADDR="..." lines).
Here's a general guide for renaming devices under EL6 (inc. CentOS 6.3, which I rename NICs under often without trouble).

Hi digimer,
Sorry, I made a mistake. "... After rebooting centos generates a device called /dev/et0. ..." should be "... After rebooting centos generates a device called /dev/eth0. ..."
CentOS made it. I got what I want.
Where is the general guide? I didn't understood what you mean.
