I thought this was kind of interesting, and I wanted to see what others thought of it.
I have two NICs in my Slack 9 box. I do't think it matters much, but I'll give the info anyway:
- eth0: RealTek 8139
- eth1: Netgear MA311 Wireless
Both cards worked flawlessly.
Anyway, I installed Slack 9.1 and all went well. Then booting the first time I noticed that I was pulling the DHCP for my internet connection. All the correct modules were loaded, and lspci
showed both of the cards as should be. What I figured out by running iwconfig
that my new OS switched the two cards, eth1 was now eth0, and vice versa.
I pulled the wireless card out and rebooted, letting it pick up the first card, and then put it back in and now everything is back to normal.
My question is this: What during the boot process determines the eth0/1 designation? Is it just a fluke and whichever card the kernel finds first gets the first device designation? Has anyone else run across this?
I just thought it was interesting.......
