Suppose you are installing Ubuntu on a bunch of identical computers, and you already know the answers to certain questions (what country and time zone you’re in, what keyboard you have, how the network should be configured, how you want to partition the hard disk, etc). You can “preseed” the answers to these questions in a very simple configuration file.

This may present some messaging problems for the big commercial Linux vendors, by the way: if the distribution underneath becomes less important, then Red Hat Enterprise Linux RHEL and SUSE Enterprise Linux Server may soon have a serious fight on their hands. In the past, one of the big differentiators has been that these “big” distros provide solid infrastructures in which business applications can be developed. If this Linux-is-Linux-is-Linux idea takes root, that will undercut a big marketing tool for Red Hat and SUSE Linux.

But I don’t think that’s going to last. The Linux community may be cocky now, but let’s think through this Linux-is-everywhere scenario a bit. If the operating system becomes just a background component that runs more web than native apps and app development for the platform itself becomes de-emphasized, then the obvious question then becomes: what does it matter it it’s Linux running on the operating system layer?
You still need a reliable OS to run the web servers which is the space RHEL and SUSE enterprise sell into.

Pyramid is binary linux distro for use on x86 embedded platforms. It is primarily focused on wireless applications however people have found many great uses for it. We primarily develop and test Pyramid for Metrix Kits, but it works well on other x86 based hardware as well. Check the WorkingHardware page for more info or add to it if you find hardware not listed that works with Pyramid.
This Linux tutorial covers TCP/IP networking, network administration and system configuration basics. Linux can support multiple network devices. The device names are numbered and begin at zero and count upwards. For example, a computer running two ethernet cards will have two devices labeled /dev/eth0 and /dev/eth1. Linux network configuration, management, monitoring and system tools are covered in this tutorial.
According to Carsten Eiram, the chief security specialist at vulnerability research firm Secunia, the flaw was introduced in the Linux kernel code in March 2011 and affects versions 2.6.39 and above. “Any Linux distributions providing these kernel versions should be vulnerable,” Eiram said.
Fedora 14 is stuck on 2.6.35 something. This shouldn’t affect CentOS builds either. Sometimes it’s beneficial not to upgrade the OS!

Zeroshell is a Linux distribution for servers and embedded devices aimed at providing the main network services a LAN requires. It is available in the form of Live CD or Compact Flash image and you can configure and administer it using your web browser.

Linux: The hole trick to bypass firewall restriction.
As long as remote is behaving itself, it will send back a “port unreachable” response via ICMP – however this is of no consequence. On the second attempt
remote# echo "hello" | nc -p 53 -u local-fw 14141
The netcat listener on console local/1 then coughs up a “hello” – the UDP packet from outside has passed through the firewall and arrived at the computer behind it.
Quagga Software Routing Suite.
Quagga is a routing software suite, providing implementations of OSPFv2, OSPFv3, RIP v1 and v2, RIPng and BGP-4 for Unix platforms, particularly FreeBSD, Linux, Solaris and NetBSD. Quagga is a fork of GNU Zebra which was developed by Kunihiro Ishiguro. The Quagga tree aims to build a more involved community around Quagga than the current centralised model of GNU Zebra.
I’m not sure I want to support this. This is what Cisco et al. do and they do this very well. As a science project maybe but why would a small or medium biz need to do OSPF or RIP? I need to think about that question for awhile.
