I have a fedora live USB stick that I want to be able to boot in a co-worker's laptop so they can run a Linux app on their Windows system. The app talks to an embedded device through wired ethernet, so I need to set a static IP address of the wired ethernet device. Is there a way to do this since the wired hardware device will be different on different computers? On one co-worker's system, wired ethernet came up as eth0. On another, it came up as eth2. We don't have a DHCP server in the embedded device, so I have to assign a static address.
Thanks,

The easy way:
Say that the ethernet device came up a eth2, then edit or create the file /etc/sysconfig/network-scripts/ifcfg-eth2. In the file put something like this:
DEVICE=eth2 BOOTPROTO=static BROADCAST=1111.2222.3333.4444 HWADDR=00:07:F5:3E:A7:6A IPADDR= 5555.6666.7777.8888 NETMASK=255.255.254.0 NETWORK=143.119.40.0 ONBOOT=yes
The DEVICE and HWADDR labels identify the NIC.
Thanks for the response...
If I understand this easy way, it requires that I know what eth device the wired ethernet will come up as. I've tested it on two laptops and one came up as eth0 and one came up as eth2. But I don't know that it won't come up as eth1 or eth3 on another system. I was hoping there was a way to configure the wired ethernet device rather than a specific eth# so I could give a USB stick to a random co-worker and expect the wired ethernet to come up with the desired IP (without knowing their eth# or hwaddr).
Thanks,
David
