Everyone,
Can anyone refer me to a tutorial as to how to rename the network cards, ie I have one that ended up being system-eth3, that I want to be system-eth1?
I am setting up a new CentOS 6.2 system that I plan to use as a gateway and e-mail server. The original machine had only one nic card, and to my surprise the vendor did not have a 1000/100/10 card that would fit in the pci-e slot. I ordered a pci-e network card, and while waiting for it to arrive I purchased a Sabrent usb 1000/100/10 to finish my development. I was able to get CentOS 6.2 to recognize the usb ethernet adapter which had been assigned system-eth1, but I could not get data to go through it (in or out).
The pci-e network card came in, and after it was installed, and upon the next boot it was assigned system-eth2. I tried to delete the usb eth1 and reassign the pci-e to eth1, but have managed to really mess things up. I deleted references to eth1 and eth2 in :
/etc/sysconfig/networking /etc/sysconfig/network-scripts
hoping that the next boot would reassign the pci-e network card as eth1, but now the system will not even recognize the new card.
Is there any way to reset the numbering sequences of network cards so that I can have the the desired names. I wish now I would have left it alone, and just changed references to eth1 to eth2 in my iptables firewall.
Thanks much,
Greg Ennis
