# The CPUTYPE variable controls which processor should be targeted for
# generated code. This controls processor-specific optimizations in
# certain code (currently only OpenSSL) as well as modifying the value
# of CFLAGS to contain the appropriate optimization directive to gcc.
# The automatic setting of CFLAGS may be overridden using the
# NO_CPU_CFLAGS variable below.
# Currently the following CPU types are recognized:
# Intel x86 architecture:
# (AMD CPUs) athlon-mp athlon-xp athlon-4 athlon-tbird athlon k6-3
# k6-2 k6 k5
# (Intel CPUs) p4 p3 p2 i686 i586/mmx i586 i486 i386
# Alpha/AXP architecture: ev67 ev6 pca56 ev56 ev5 ev45 ev4
# Intel ia64 architecture: itanium
#
# (?= allows to buildworld for a different CPUTYPE.)
#
CPUTYPE?=p3
#NO_CPU_CFLAGS= true # Don’t add -march= to CFLAGS automatically
#NO_CPU_COPTFLAGS=true # Don’t add -march= to COPTFLAGS automatically
#
# CFLAGS controls the compiler settings used when compiling C code.
# Note that optimization settings other than -O and -O2 are not recommended
# or supported for compiling the world or the kernel – please revert any
# nonstandard optimization settings to “-O” before submitting bug reports
# without patches to the developers.
# Note also that at this time the -O2 setting is known to expose bugs in
# libalias(3), and possibly other parts of the system.
#
# for ports
#CFLAGS= -O3 -pipe -fomit-frame-pointer
# for build world and kernel module
COPTFLAGS= -O2 -pipe -fomit-frame-pointer
CFLAGS+= -mfpmath=sse -mmmx -msse -m3dnow -maccumulate-outgoing-args
-minline-all-stringops

## -mfpmath=sse:
PentiumIII相容的CPU可以打開-mfpmath=sse代替傳統i386的浮點運算，加快速度。
## -mfpmath=pni: Pentium4
Prescott相容的CPU可以打開-mfpmath=pni代替傳統i38i的符點運算，加快速度。
## -mmmx:
打開mmx指令來增加code性能。適用于PentiumMMX相容CPU。
## -msse:
打開sse指令來增加code性能。適用于PentiumIII相容CPU。
## -msse2:
打開sse2指令來增加code性能。適用于Pentium4相容CPU。
## -m3dnow:
打開3DNow!指令來增加code性能。適用于K6、Athlon相容CPU。

## -maccumulate-outgoing-args -minline-all-stringops
通過减少某些動作來實現加速，比較穩定。

把這段加到你的/etc/make.conf裡………

建議更新 port tree 的話可以用 C 改寫的 csup (若使用是 FreeBSD 6.2-RELEASE 則已經進入 base system)，然後在 make.conf 內貼上

SUP_UPDATE=yes
SUP=/usr/bin/csup
SUPFLAGS=-L 2
SUPHOST=cvsup.tw.FreeBSD.org
PORTSSUPFILE=/usr/share/examples/cvsup/ports-supfile

然後 cd /usr/ports;make update 就可開始 update port tree 了~~

公司的垃圾信件常叫人頭痛,雖然已安裝MailScanner和SpamAssassin但還是常常會有 幾百封垃圾信,原因出在MailScanner只能處理進來主機以後的信件,沒辦法做到”境外決戰”,所以找了一套不錯的小軟體來安裝,看看是否真的如我 所要求的可以達到境外決戰的目的,如此一來可以降低網路流量, 也可以做到針對廣告信件來源持續長期封鎖的目的….

要安裝之前請先檢查環境是否有以下套件：

perl module Number::Format.
perl module HTTP::Date.
Perl module Net::DNS
Perl module Net::CIDR (should already be there – used by MailScanner)
Perl module GD::Graph (this requires the GD library)
Mailscanner.
Spamassassin.
GEOIP Database and perl module (optional).
perl module Mail::Sendmail

然後再到官方網站http://www.while.org.uk/mailstats/下載最新版本的Vispan(目前最新版本為2.1.0)。

整個安裝過程非常簡單,只要下兩行指令就搞定：
perl Makefile.PL
make install

接著編輯/etc/Vispan.conf，修改以下主要設定：

UseIPTables = 0
如果mail server沒有啟用iptables這段就設”0″,若有就選”1″,啟用iptables有個好處他會自動設定rule擋掉廣告信件主機IP,不過問 題來了,萬一有個數千筆垃圾信件IP,那iptables的rule就變數千條,會累死人的,所以建議不要啟用。

BlockTime = 7200 # 5 day
一開始因為廣告信件很多,如果將IP Block太久怕會影響Server效能,所以先用預設值觀察幾天看看,過幾個星期後再慢慢將Block時間調久一點。

HTMLDir = /var/www/html/www/vispan
設定報表頁面路徑。

Scanner = sophos
設定你的防毒軟體名稱,Vispan會統計病毒數量。

SMTPServer = mail.myhost.com
設定你的SMTP。

其他的就依個人需求逐一調整設定,小弟不在這裡贅述了。接下來看看Maillog的結果,如果出現以下訊息即代表已經在跑囉！
arg1=[125.243.83.26], arg2=125.243.83.26, relay=[125.243.83.26], reject=550 5.0.0 We do not accept junk mail
注意喔,他是reject不是discard….

報表頁面Demo

萬一遇到不小心被Block的IP怎麼辦?
先到/etc/mail/access刪除被擋的IP,然後將IP加到/etc/MailScanner/rules/spam.whitelist.rules裡就可以了。

原本採用舊的 Vmware player (1.x)，在同樣一台電腦上(P4 2.4G , 768M RAM, 18G SCSI H.D)，跑同樣的appliance ，速度很不錯，至少指令都可以即時回應。在 program files 底下可以發現安裝後的player 程式大約是5x MB。
昨天就偏偏手癢，去抓了新的player (2.0 beta)，安裝之後，哇塞，馬上”驚為天人”，這是哪門子的程式啊！同樣的virtual Machine ，開機不但變慢，而且光在login 畫面，就讓我連續發生兩次login timed out!
輸入指令起碼等上30秒才會看到有回應！！
所以乾脆放棄了，去找了workstation版本來安裝看看，希望會有好結果！

                      嘸蝦米隱藏功能                  

在嘸蝦米輸入法模式下輸入以下指令：

,,x  => 嘸蝦米解碼翻譯
,,j  => 切換成日文輸入模式 (前提是要會日文五十音)
,,t  => 切換成繁體中文模式輸式
,,c  => 切換成簡體中文輸入模式
,,ct => 切換成台式簡體輸入模式 (以【繁體中文模式輸式】解碼，即可得到【簡體中文】)

備註：
,,x 的使用方式，先輸入一串嘸蝦米解碼字，如：ix qm e neq yb jn bn ，
然後選起來，按右鍵選複製，在輸入 ,,x，就會變成 【我們一家都是人】，試試吧。
