pppoe server howto

I have spent all of my working day to setup rp-pppoe server on Linux PC for test pppoe client.
so, I though it should be recoded to, for easy setup in the next time.

Mandrake 10.1
o ppp-2.4.2.
o ra-pppoe for plugin, which including pppoe-server.

[root@localhost ppp]# cat pppoe-server-options
# PPP options for the PPPoE server

# LIC: GPL
require-pap
login
lcp-echo-interval 10
lcp-echo-failure 2
plugin rp-pppoe.so

[root@localhost ppp]# cat chap-secrets
# Secrets for authentication using CHAP
# client server secret IP addresses
vincent * 1234 *

below message from debug.

however, It seems could not dailin from windowsXP pppoe.
pppoe-server always complain source MAC should be 00:00:00:00:00:00 then
terminate with PADT.

不易使用的apt source.list

用apt-get來update or install 是很方便，但一但萬一有mirror site有問題時就另人頭大了
每次用來update source.list就花我一兩小時…因為我不熟^^，和我的mandrade的urpm一樣…
我也不熟它們的機制。

看一下裡面的檔案架構大概是這樣

cvs vs svn

最近要用cvs
所以比較了一下和svn的不同

工作效率低落

在一家公司"混"久了就會有這樣的情況
發現看起來很"忙"
可是捫心自問 - 自已真的是一天八小時有在為公司做事嗎?
相信很多人都和我一樣吧!
尤其是早上時間~大概是我最混的時段~~~

工作這麼久了，最近才在開始找方法來改善效率問題，
主要是工作量漸漸的增加後，一天在公司八小時實在是不夠，
例如上來個meeting，下午來個電話，然後再解個bug好了，剩下的時間就不多了，
如何利用一些片段的時間再處理小事情就變得很重要了，ex:
處理一封簡單的mail
了解一下其他members的進度
or如何利用早上的時段對我也很重要

NFS client

這個sample mesages說不能mount remote dir，一般來說kernel有support nfsclient，設定應該也沒錯，我check一下…exportfs -arv就ok了
另一個可能是kernel 沒built-in "nfsclient root" options,
