There is an implicit setting in Thunderbird. It will treat the attachment with "inline" in the attribute of "Content-Disposition", which will trigger the attachment be showed in mail body when viewing.
There is a way to turn it off.
In Thunderbird,
Tools -> Options -> Advanced -> General -> Config Editor
Set the value of "mail.content_disposition_type" to 1
Now, it works.
BTW, I read Aaron Toponce's article to get this useful solution and you can find the article here.

ssh-agent start up scritp
To activate ssh-agent when login, I put some scripts in my bash profile.
=> .bash_profile
=> .bash_logout
=> .bash_profile
#-------------------------------------------------------------------
SSH_ENV=${HOME}/.ssh/environment
function start_agent {
echo -n "Initialising new SSH agent..."
sleep 1
ssh-agent | sed 's/^echo/#echo/' > ${SSH_ENV}
echo "succeeded!"
source ${SSH_ENV}
ssh-add;
}
# Source SSH settings, if applicable
if [ -f "${SSH_ENV}" ]; then
source ${SSH_ENV}
#ps ${SSH_AGENT_PID} doesn't work under cygwin
( ps -ef | grep ${SSH_AGENT_PID} \
&& ps ux| grep ${SSH_AGENT_PID} ) \
> /dev/null || {
start_agent
}
else
start_agent
fi
=> .bash_logout
#-------------------------------------------------------------------
function quit_agent {
echo -n "Cleaning ssh-agent settins..."
sleep 1
ssh-add -D
ssh-agent -k > /dev/null 2>&1
unset SSH_AGENT_PID
unset SSH_AUTH_SOCK
echo "succeeded!"
sleep 1
}
if [ ${SSH_AGENT_PID+1} == 1 ]; then
echo -n "Quit ssh-agent? (No or Yes) "
while [ 1 ]; do
read ANS
case ${ANS} in
[Yy][Ee][Ss]|[Yy])

sleep 2

FreeBSD under VMware, the time is delay
I found out my freebsd6.2 was complained about time is delayed.
After google, I found this post is useful, FreeBSD detects time via APIC.
You can set following line in /boot/loader.conf
hint.apic.0.disabled=1
Then reboot your FreeBSD, things will go to be different.

C shell裡頭的&&, ||
在 C shell 裡頭有兩個condition commands, 分別是&&以及||
&&指的是
當第一個指令執行成功就繼續執行第二個指令
且第一個指令執行失敗則第二個指令就不執行
ex.
mkdir work && touch work/file
||指的是
當第一個指令執行成功就不執行第二個指令
而第一個指令執行失敗就繼續執行第二個指令
ex.
mkdir work || echo "Create directory fail"
&&指的是

ex.
mkdir work && touch work/file
||指的是
當第一個指令執行成功就不執行第二個指令

ex.
mkdir work || echo "Create directory fail"

awk的使用
目前需要寫幾個小東西, 之前看過awk的用法,想來很適合目前的工作
這邊有個找到的資料
希望派的上用場
AWK主要結構
Pattern { Actions }
Pattern: relational operation
>, <, >=, <=, ==, !=, ~, !~
Actions: I/O command, scenario control command
print, printf(), getline
if(...) {...} else {...}, while(...) {...}
if pattern is true, we do actions!
AWK欄位變數
$0 一字串,目前AWK讀入的資料列
$1 代表$0上第一個欄位的資料
$2 代表$0上第二個欄位的資料
$3 代表$0上第三個欄位的資料
... ...
AWK內建變數
NF 表$0上讀入的欄位數目
NR AWK已讀入的資料列數目
FILENAME AWK正在處理的資料檔名
UNIX命令列上, AWK的用法為
# awk '{print $1, $2, $3 * $4}' file.data
而符號 ' 是用來夾住pattern{actions}的, 另外, 若是程式太大需要寫在別的檔案裡頭,則
# awk -f program.awk file.data
AWK的Regular Expression
/... / 常用來包住Regexp
^ 表示該字串出現在字首 (ex. /^the/)
$ 表示該字串出現在字尾 (ex. /the$/)
. 表示為任一字元
* 表示為前字元出現重複次數的字元(ex. /a*/用來比對a不管有無出現或是出現多次的情況)
+ 表示為前字元出現一次以上的字元(ex. /a+/用來比對a至少出現一次以上)
? 表示為前字元不出現或是只出現一次(ex. /a?/用來比對a不出現或只出現一次)
\ 則為跳脫字元 (ex. /filename\.suf/)
[...] 表示為字元集合 (ex. [ab] 用來比對[a]或[b])
[..-..] 表示字元範圍 (ex. [0-5]用來比對[12345])
[^...] 表示字元的補集(ex. [^a]用來比對非[a]以外的字元)
(...) 用來括住一群字元成為一段字串(ex. /(ab)+/用來比對ab, abab, ababab等)
| 表示為判斷的或(ex. /os | apps/用來比對os, apps)

SSL Handshake Sequence
參考apache的圖
Phase 1
Establish protocol version, session id, cipher suite, compression method
Exchange random values
01. => ClientHello
02. <= ServerHello
Phase 2
Optionally send server certificate and request client certificate
03. <= ServerCertificate
04. <= CertificateRequest
05. <= ServerHelloDone
Phase 3
Send client certificate response if requested
06. => ClientCertificate
07. => CertificateVerify
Phase 4
Change CipherSuite and finish handshake
08. => ChangeCipherSpec
09. => Finished
10. <= ChangeCipherSpec
11. <= Finished

sendmail + dnsbl + spamassassin
大概算是這陣子才對這些東西比較熟悉吧
過一陣子再多加上些統計的資料
然後就把一大堆 services 上線吧
太忙了 =.=+
不過也應該是我動作太慢的緣故吧

Apache 的市佔率
Netcraft做了一份 200502 網頁伺服器市佔率的統計, 目前 apache 的 httpd 已經到達四千萬的數字, 市佔率達到69.95%, 感覺就很恐怖
同一時刻, Microsoft 的網頁伺服器市佔率也到達 22.68%
恩恩...看來我還是會繼續用 apache httpd
