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.

My connection goes down every now and then (totally randomly -sometimes twice in a minute, sometimes once every half-hour) and my linux box goes "mute". It can't be pinged, nor can it ping out. XP works fine for hours (dual-booting on the same machine). So I'm sure its Linux, not hardware or my network infrastructure here. Other PC's using XP on the same LAN and the same router to get to the internet have no problems.
What causes dropped packets? How can I fix it so none are dropped?
NIC as indicated by lspci. I'm running the RealTek Linux driver for this card.
I further also massively increased certain buffersizes that were autotuned by the kernel. I've not tested if the queue length was the deciding factor (it works, so I want to leave it as it is!) but I also did this:
Ok, I'm giving up trying to get this card to work in Linux.
It seems the r1000v5.tgz driver from Realtek is buggy for the 8168B/8111 Gigabit Ethernet adapter on the GA-945PL-S3 motherboard. The problems kept persisting, and the NIC is unusable so regularly under 22.214.171.124 it just as well could be absent from the system.
I disabled it in the BIOS and put in a Realtek RTL-8139 card in an open PCI slot and I'm now using that with the 126.96.36.199 kernel on my GA-945PL-S3 motherboard. Everything's fine now.
It seems like the Realtek RTL-8168B/8111 Gigabit LAN adapter is unusable with 188.8.131.52 with the Realtek r1000v5.tgz driver, at least until Realtek maybe releases a new version that will fix the ENOBUFS bug on the current driver for the RTL-8168B/8111 provided by Realtek.
