【Unix-like】DNS-浮動IP申請
對於架主機的人來說
pppoe最頭疼的就是每次得到的IP都不相同，
這樣要怎麼從外面連到自已家的主機呢？
在WIN底下有DynDNS Updater這套軟體好用！
那…在FreeBSD、Linux/UNIX-like OS底下呢@@？
呵呵別擔心~當然也有啊！
=========================
【申請DynDNS 帳號】
首先我們先去申請一個免費的 host name
這邊提供一個本人自已在用的網站DynDNS
1. 點選『Create Account'連結
點選右上角的『Create Account' 申請帳號。
2. 填寫帳號資訊後，點按下方的『Create Account'按鈕
資料填完之後就是DynDNS的會員囉:3
3. 打開信箱，收取郵件
4. 點選帳號啟動連結
(網路上還有很多其他免費的動態DNS，有興趣的朋友可以自行去找找)
【設定Hostname】
接下來要申請一個動態的DNS(Dynamic DNS)
點選 
>>點選 
>>點選
>>點選 
>>點選 
>>設好喜歡的『Hostname』、選擇『Service Type』及填入目前的『IP Address』，最後按下右下方的『Add to Cart』 按鈕，這樣就申請完了^^！
再次登入，點選左方
圖示連結，進入下面畫面，並點選右下方『Next>>』按鍵。
進入下方的頁面，點選右下方『Activate Services>>』，令剛申請、設定的Hostname生效。
ddclient=============================
為了不想每次重開或斷線後就要上DynDNS去更新ip
我們要來安裝一個可以自動連上DynDNS更新IP的Update軟體
【Download ddclient】
DynDNS站上就能下載到這套軟體：ddclient
下載下來後解壓解包它 ddclient.tar.gz
# wget -c http://cdn.dyndns.com/
# tar -zxvf ddclient.tar.gz
解開後就看到這個ddclient-3.7.3 的目錄
安裝的方法可以cat 一下README
******************************
【INSTALLATION】
# sudo cp ddclient /usr/local/bin/
# sudo mkdir /etc/ddclient
# sudo mkdir /var/cache/ddclient
# sudo cp sample-etc_ddclient.conf /etc/ddclient/ddclient.conf
# touch /var/cache/ddclient/ddclient.cache
# sudo chown -R root:root /etc/ddclient
# sudo vi /etc/ddclient/ddclient.conf
-- and change hostnames, logins, and passwords appropriately
******************************
(for Ubuntu,Fedora,Linux/Unix-like)
【修改 /etc/ddclient/ddclient.conf 內容】
>use=if, if=ppp0
>login=jackiexie
>password=xxxxxxxxx
>server=members.dyndns.org
>protocol=dyndns2
>jackiexie.blogsite.org
>EOF
# cat /etc/ddclient/ddclient.conf
|
daemon=300 protocol=dyndns2 |
