RPM package is a powerful utility to manage the software in all major Linux distributions. RPMs can be used to,
- Install packages
- Remove packages
- Upgrade packages
- Verify packages
Here are some useful command to manage RPM packages,
1. Getting detailed information about the package httpd
rpm -qi httpd
/etc/net is a new way to configure networks. It is designed to let you use all modern Linux network technologies in a convenient way. The best way to learn /etc/net is to look at examples, which I will try to provide for most technologies mentioned at LinuxNet pages.
You can find more information at the project's home page and freshmeat page.
I created a bridge that include eth0 and the bridge in preparation to setup Qemu with a bridged interace to the network.
ifconfig eth0 0.0.0.0 promisc up
brctl addbr br
ifconfig br 172.16.2.1 netmask 255.255.255.0 up
I have echoed 1 in /proc/sys/net/ipv4/conf/eth0/proxy_arp
I finish setting this up and evrything is fine. I ping the default gateway of the machine in the network attached to the eth0 interface and I get excellent replies.
Here is the problem, I vnc to 172.16.2.1 and once I do that, I loose communication with 172.16.2.1.
Q: Why can I ping an IP address when the interface is down?
A: Linux uses a "host based" addressing model, IP addresses are owned by the host, not individual interfaces. So as long as the IP address is configured to some interface, we will accept packets destinated to that IP address as our's.
A collection of programs that form the base set of the NET-3 networking distribution for the Linux operating system. This package includes arp(8), hostname(1), ifconfig(8), ipmaddr, iptunnel, mii-tool(8), nameif(8), netstat(8), plipconfig(8), rarp(8), route(8) and slattach(8).
Please refer to the Ethernet page for more up to date information. This page is ancient and some love could be used to organize this information a little better under the ethernet section

The Spanning Tree Protocol (STP) is used to allow multiple bridges to work together. Each bridge communicates with other bridges to discover how they are interconnected. This information is then used to eliminate cycles, and provide optimal routing of packets. STP also provides fault tolerance, because it will recompute the topology if a bridge or port fails.
This page has heresay or limited information and may needs a more analytic basis
Provide a listing of motherboards and how well they are supported.
If work-arounds are needed, for example, disabling ACPI, or tweaking the BIOS, that information is welcome here.
