Hello,

Just to see if anoyone of you knows a solution for the problem described in threads http://forums.gentoo.org/viewtopic-p-3061274-highlight-.html#3061274 and http://forums.gentoo.org/viewtopic-t-427207.html. To make a short summary, the problem is that Gentoo only recognizes one MAC hardware address, but I have two NICs installed, even from Gentoo Minimal Install Disk. I have already enabled OpenBoot variable local-mac-address and it works on FreeBSD, but I have powerful performance reasons to use Gentoo.

I need to find a solution before tuesday, because the next week after that there will be some experiments on the lab. In case I can't solve it I'll have to switch to some UNIX. The project is a cluster for academic research and part of my intentions is to show linux performance advantages (Gentoo by excelence), if it has success the project will be founded for all public universities on that open source strategy. Also, I've been working on a cluster installed baed in Gentoo. The project can be accessed in http://sourceforge.net/projects/beowulf-cenat (we are starting)

Thanks for your time and any suggestion is valuable.

A quick and easy fix for this is to use net-analyzer/macchanger in combination with the configurable options for it documented in /etc/conf.d/net.example

I configured macchange according to net.example this way:

Quote:

# Change mac address
mac_eth0="random-ending"

# Use dhcp
config_eth0=("dhcp")

# Use second nic for internal network
config_eth1=("10.0.1.100 netmask 255.255.255.0 brd 10.0.1.255")


Up to now I have the dhcpd server running on eth1 and it works neatly. Also, I've been able to mount NFS's /home and /usr/portage (to avoid excessive downloads).

The problem with eth0 remains. Card's address is effectively changed. dhcpcd just dies without message, but dhclient says there is no dhcpoffer service. It is false (already checked that eth0 were up), I wouldn't be browsing otherwise.

At least I have the internal LAN, but I need internet access.
