pxe 網路開機
最近突想做pc的網路開機,整整再google找了兩,三天,總算有幾篇教導利用 pxelinux 做開機的方式,我的做法如下
- 主機 fedora5
- 安裝 tftp-server => 修改 /etc/xinetd.d/tftp =>將 disable = no
- 安裝 dhcp => 修改 dhcpd.conf 如下
server-identifier 10.0.0.254; #在多張網路卡的時候可以加上﹐可不設
allow booting; #將 dhcp 提供 bootp;
allow bootp; #將 dhcp 提供 bootp;
option domain-name "fhsh.tp.edu.tw";
option domain-name-servers 168.95.1.1,168.95.192.1,10.0.0.254;
default-lease-time 3600;
max-lease-time 7200;
authoritative;
ddns-update-style none;
log-facility local7; #加這三行
server-name "PXE Server";
server-identifier 10.0.0.254;
subnet 10.0.0.0 netmask 255.255.0.0 {
range 10.0.0.50 10.0.0.250;
range 10.0.1.50 10.0.1.250;
option routers 10.0.0.254;
option broadcast-address 10.0.255.255;
filename "pxelinux.0"; #從 tftp 下載執行檔
next-server 10.0.0.254; # tftp 的 ip 位置
} - 抓下pxelinux工具 http://syslinux.zytor.com/download.php
主要是用到裡面的pxelinux.0、memdisk和menu.c32，將這些檔案放到tftp的根目錄下 - * 修改 tftp目錄下的 pxelinux.cfg/default,第一次需先建立目錄與檔案，範例如下
DEFAULT menu.c32 '預設以menu.c32這個核心來啟動，即出現選單
PROMPT 0 '不要用prompt的方式，即啟用選單
ALLOWOPTIONS 0 '不要該使用者有選擇權，例如更改啟動參數或直接離開選單
TIMEOUT 50 '選單的提示時間，50好像是指5秒
MENU TITLE PXELinux Menu '選單的標題
LABEL freebsd54 '名稱
MENU LABEL BSD '選單上的標題
kernel memdisk '用來啟動影像檔的核心，pxelinux提供
append initrd=fbsd54.img c=812 h=255 s=63 '要載入的影像檔及參數，此例為將bsd的bootonlyCD所做成的PXE影像檔
LABEL local
MENU DEFAULT LOCAL ' MENU DEFAULT 是預設選單指向
LOCALBOOT 0 ' 直接以硬碟開機
LABEL dos
MENU LABEL DOS
kernel memdisk
append initrd=dos.img ' 將磁片做成影像檔後，直接放進來就可以用了，不用加參數，下面的也都是直接用磁片所做成的影像檔
LABEL ghost2003
MENU LABEL ghost2003
kernel memdisk
append initrd=ghost2003.img - 我喜歡這種方式,可以依照自己喜歡增加開機選單,利用 gohot 做開機檔,再利用 linux 的 dd 指令,做成 img ,真方便
dd if=/dev/fd0 of=ghost2003.img - 如果 dhcp 用 windows 只要將它設定 bootp與dhcp都提供,再增加 66,67兩項選項的設定
在 dhcp =>內容=>進階=>勾選 只有BOOTP 或 兩者都可以
在 dhcp=>伺服器選項=>設定選項=>66 填入 tftp 主機 ip =>67 填入tftp給 pc 的啟動檔,這裹是 pxelinux.0 - 以後採購電腦一定要求網卡有支援 pxe 網路開機功能才方便

Cultivated for industrial and industrial functions, Cannabis Sativa, more extensively-known as Hemp, is
known for its versatility. It can be used for fuel, food,
cleaning soap, cosmetics, building supplies, paper, and clothing.
Although Canada grows this plant mainly for seeds, its use as a
wearable garment is now increasing in popularity. Consequently, hemp production on this nation has greater than doubled within the final decade.In 1999,
Canada allotted 2,four hundred hectares
specifically for hemp production. In 2009, the acreage was increased to
five,600 hectares. These new type of clothes commands a gradual improve in demand.
This has finally led Canadian farmers to point out a growing curiosity in the development of hemp and its uses.
Hemp generates a better revenue per hectare than that of cotton's.Clothing materials made out
of this beneficial plant is often blended with cotton to make the top-product softer as opposed to
its pure attribute which is tough and coarse.
While cotton usually consumes more resources, the Canadian National Useful resource Council or NRC was partly capable of patent a ground-breaking
enzyme course of that transforms industrial hemp into white, smooth,
Canadian cotton. This cloth is now popularly referred to as
Crailar. This development has stirred and prospered the Canada trend industry.Local garment retailers, naturally displaying their aggressive edge, have appealed
to the eco-friendly society and emphasized truthful commerce
ethics of Canadian-made garments, so there have been drawbacks that the Canada hemp clothing business had to face.
First, its affiliation with marijuana had led to the belief that the supplies used for
this material have been produced illegally. Hemp products have been then mistaken to have been favoured only
by hippies and made it look inappropriate to use as commonplace apparel.

Hi! This is kind of off topic but I need some help from an established blog.
Is it tough to set up your own blog? I'm not very techincal but I can figure
things out pretty quick. I'm thinking about setting up my own but I'm not sure where to begin. Do you have
any points or suggestions? Thank you
