Hello:
As I continue dealing with iptables, another issue has come up that I
can't tell is a mis-understanding on my part or a potential problem
I have three F16 machines, one x86_64 and two i383/686. If I run
/sbin/ifconfig on them, I get (short summary of):
x86_64: eth0
i686: em1
Just to add fuel to the fire:
Soon more and more systems will have UEFI as well as, or instead of the
old BIOS. On most newer sever class systems, the traditional BIOS is
*emulated* in the EUFI.
The EUFI, and, therefore, newer BIOS, can provide much more information
to the OS than before.
Linux kernels are attempting to be more 'aware' of the new information.
It will provide much better control and flexibility with devices.
That being said, you can avoid it all for now, by adding 'biosdevname=0'
to the kernel command line in grub, or upon boot. Already defined
devices will not change, but if you include that argument during
installs, or on LiveCDs, you will get the old consistent device names,
ie: eth0, every time.
The fact that two fresh installs got one old (eth0) and one new (em1)
device definition, shows the difference in the two versions of BIOS, NOT
anything to do with 64 bit vs 32 bit.
Good Luck!
