Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Distribution: Mandriva 2010 (cooker) with Bind9, Sendmail, Postgresql and Apache2 servers
2WIRE need bridge for static lan ips
I have managed to get myself in ever tightening circles over this one.
Have a server running Mandriva 2007.1. Run our own dns because we run our own mail server as well as others. The system has 3 nic cards. Formerly, we relied on a D-Link router which cashed in its chips 2 weeks ago. My isp provider replaced it with a 2WIRE 2700HG-E. Firewalling suddenly became a problem. Previously, we had relied totally on shorewall to limit port access.
I know at the software level I have to introduce split-dns and make some adjustments in sendmail. That's okay.
My problem is the 2WIRE hookup.
I first set up the 3 nic cards for dhcp. 2WIRE shows the devices as being 'present' but at this point it is the luck of the draw as to which is labeled 'active'. That's understandable for the moment. Not much to choose between, after all.
Then I enabled the bridge network because I think that is what I need to do from all the colvoluted reading I've done on this.
But I need 2 of these devices to be reassigned to static ips for the benefit of the local dns and mx hosts. I just cannot get my head around how this is to be done.
Hopefully, there is someone out there who has passed this way before and can give me a pointer or two. I must add that the isp provider's version of 2WIRE does not include the mdc (diagnostic) console, which might have allowed me to help myself a bit more.
I recently received a 2Wire 2701 from my ISP and I'm attempting a similar setup.
So far I've been able to use the "Public Proxied Subnet" setting to pass 1 public IP to a pfSense firewall behind the 2Wire. I've attempted to assign another public IP to a separate interface (also on the pfSense), but it seems like the 2Wire identifies the host by using the hostname. As a result, it will not allow me to assign a separate IP for the second interface because the hostname is the same for both. Why the 2Wire does not rely on MAC addresses to identify the host is anyone's guess.
Anyway, still working on the problem and I'll post any progress here. Sounds like we need someone with more experience with the 2Wire gateways as I have none.
lspci | grep net
dmesg | grep -i "net"
dmesg | grep -i "eth"
ip link show
Here follows a short summary of what these commands do.
show pci modules located, and search for "net"
show whether the kernel picked up a driver for these cards
show whether they have been assigned eth numbers
show the link status of ethernet devices
If you are haveing driver issues, you may want to lay your hands on realtec 8139 NICS
they are the most common, and unless i'm mistaken, the d-link cards also use the realtec 8139 modules
