PS:如果要讓proftpd不使用unicode,可把unix系統設為big5後才編譯,也記得在configure時不要加--enable-nls
修改/etc/sysconfig/i18n
將LANG="zh_TW.UTF-8"
改成LANG="zh_TW.BIG5"再重開機
編譯完就可以改回來了 XD
PS:改成BIG5以後,能夠不再改就不要改,因為,有遇過客戶端軟體造成的怪異問題
這個對於只會用IE開FTP的人有用.(說穿了,就是全部統一使用非Unicode,就算你用Smartftp或是FileZilla來連也一樣,雖然FileZilla會嘗試用UTF8處理...)
或者是
在proftpd.conf裡設定UseUTF8 off
新版的proftpd.conf(1.3.2rc1)是設UseEncoding off 或 UseEncoding cp950 cp950
(在1.3.2正式版上未測試)

ftp utf-8 big5

xp的下的檔案總管不支援ftp utf-8的檔案名，只能用big 5

所以pureftpd.conf必須要配合調整一下。

compile --with-rfc2640

FileSystemCharset big5

ClientCharset big5

vista底下的ftp就support utf8 filename

pureftpd anonymous delete resume rename file

os:freebsd 6.1

使用pure-ftpd想要開啟anonymous delete resume rename file

必須在configure前就要 setenv

setenv CPPFLAGS "-DANON_CAN_DELETE -DANON_CAN_RENAME"

cd /usr/ports/ftp/pure-ftpd

make install clean

就可以了

setenv CFLAGS not work。

Hi again.

What follows is something extremely confidential, private, undocumented
and top secret. But as you subscribed to the shiny pureftpd-users
mailing-list, you need to know. Maybe this is dangerous. Maybe if
someone knows that you've read this, special agents will murder you.
So you're free to delete this message without any further reading now.

Still here? Are you sure?

Well...

Ok.

Apart from ./configure and run-time options, there are some
undocumented switches in Pure-FTPd. They are undocumented because they
were only designed for testing/debugging, or because they are uncommon
needs.

But if you are strong, you can play with these undocumented switches.

To enable them, you have to recompile pure-ftpd with something like
that :

env CFLAGS="$CFLAGS -DSTRICT_REST -DLOG_ANON_EMAIL" ./configure
make install-strip

Add as many -D as you want here.

Here's a list of these top secret features :

* ALWAYS_RESOLVE_IDS :
Always try to get full user names, even once chrooted. If you define
this, you can put a fake etc/passwd file (or similar, like pwd.db) in
a chrooted environment to get user names.

* ANON_CAN_CHANGE_PERMS :
Allow anonymous users to chmod files.

* ANON_CAN_DELETE :
Allow anonymous users to delete files.

* ANON_CAN_RENAME :
Allow anonymous users to rename files.

* ANON_CAN_RESUME :
Allow anonymous users to resume uploads.

* AUTORENAME_REVERSE_ORDER :
When autorename is enabled, put the unique id at the beginning of
file names, not at the end. Useful if you want to keep extensions.

* DEFAULT_TO_BINARY_TYPE :
Default to binary transfers even if 'bin' ('TYPE I') hasn't been
issued by the client.

* DISABLE_MKD_RMD :
People can't create/delete directories any more.

* DO_AUTHD_TIMEOUT :
Send an ALRM signal to an authentication module after 60 seconds.

* FANCY_LS_DIRECTORY_HEADERS :
Display 'ls' with multiple directories with lovely headers. This is how
the good old first releases of pure-ftpd were displaying things.
Unfortunately, it breaks parsing with some clients (like ncftp with a
recursive get) . But I really feel nostalgic when I see these headers
again.

* LOG_ANON_EMAIL :
Log what anonymous users have entered in the 'password' field.
Except for SPAM, I don't see any reason why people would enable this.
So no, no, no, don't ask, it won't become a standard feature.

* NON_BLOCKING_DATA_SOCKET :
Create transfers socket with O_NONBLOCK.

* RFC_CONFORMANT_LINES :
Assumes that all clients will end their command lines with \r\n as
expected. Unfortunately, in the real life, this is not always the case.

* RFC_CONFORMANT_PARSER :
Allows control characters and other horrible stuff in commands and
file names.

* SAVE_DESCRIPTORS :
Save file descriptors by closing/reopening the log after/before
every logged message. Slow, painful, and not chroot-friendly.

* SKIP_COMMAND_TRAILING_SPACES :
Trim spaces after commands, so that 'STOR xyz' is the same as 'STOR
xyz' . For brain damaged clients.

* SNPRINTF_IS_NOT_BUGGY :
Asserts that your snprintf() function works the ISO C99 way. Never
enable this on binary packages.

* STRICT_REST :
Disallow REST commands in ASCII mode (or at least : reply with an
error code) .

* WITHOUT_PAM_SESSION :
Do PAM authentication, but don't open PAM sessions.

Have fun...

ffdshow thumbnails rundll32 crash

vista 底下，使用k-lite codepack 5.0

不知道為什麼看某個錄製的mpq時，一直會有rundll32 dep crash的問題...

原來是因為檔案總管自動建立thumbnails的問題。

設定了資料夾的檢視方式，使用「 Always show icons, never thumbnails 」就正常了。

不過缺點是jpg檔，也不會有thumbnails，要用預覽，或是用xnview等軟體。

或是也可以用另一種方法，讓某些副檔名的檔案不要產生thumbnails。

You can disable auto creation of thumbnails in Windows Explorer for videos files pr extention.

Just delete the following registry key:

HKEY_CLASSES_ROOT\[Extention]\ShellEx\ BB2E617C-0920-11d1-9A0B-00C04FC2D6C1

Replace [Extention] with the extention of your choice like:

.avi

.vob

.mpg

.mov

.vmw

If you at one point want it back again, just create the key again and reboot. And Vista will again happily suck all the power out of your computer, when opening a folder with lots of video files...

FreeBSD 7.2 ipnat ipfilter

新的版本，基本上都不需要再重編kernel，為了一點效能，而整個重編kernel也很麻煩，而且現在cpu都太快了。

rc.conf:

ppp_enable="YES"

ppp_mode="ddial"

ppp_profile="pppoe"

ipfilter_enable="YES"

ipnat_enable="YES"

ipmon_enable="NO"

ipmon_flags="-Ds"

/etc/ipf.rules

FreeBSD 7.2+Apache22+PHP+mysql51

1. Fresh Install a FreeBSD 7.2-RELEASE

install from ftp6.tw.freebsd.org

2. portsnap fetch extract

3. mysql51-server (for a long time)

mkdir /usr/local/mysql

chown /usr/local/mysql user:mysql pw:mysql

用ln -s 於/var/db/mysql建link至/usr/local/mysql(可省略)

make WITH_CHARSET=utf8 WITH_XCHARSET=all WITH_COLLATION=utf8_general_ci BUILD_OPTIMIZED=yes BUILD_STATIC=yes install clean

cp /usr/local/share/mysql/my-huge.cnf /var/db/mysql/my.cnf

ee my.cnf

[mysqld]

skip-name-resolve

4. install apache22 (for a long time with perl)

make config

BerkleyDB(subversion) mod_proxy all

/etc/newsyslog.conf

#newsyslog

/var/log/httpd-access.log 644 3 1 @T00 Z

/var/log/httpd-error.log 644 3 1 @T00 Z /var/run/httpd.pid

modify apache22.conf

#kenny

AddType application/x-httpd-php .php

AddType application/x-httpd-php-source .phps

5. install php5

6. install pure-ftpd

7. http://blog.cheyingwu.tw/index.php/2007/05/04/freebsd-utf8-env/

FreeBSD UTF-8 環境

FreeBSD 5.x 以上，就已經支援 i18n，之前因為 ftp 日文檔名的問題，所以全面 utf-8 記錄一下整個過程

改 csh 的登入設定

#~/.cshrc setenv LC_ALL zh_TW.UTF-8

安裝 convmv 轉 big5 中文檔名

cd /usr/ports/converters/convmv make install clean;rehash

使用法

convmv -f big5 -t utf-8 -r --notest [檔名 or 目錄名]

檔案內容編碼用 iconv 轉

iconv -f big5 -t utf-8 檔名 > 檔名

重編 pure-ftpd 支援 RFC 2640，在 Makefile 裡面加上

--with-rfc2640

編完後編輯 pure-ftpd.conf

FileSystemCharset utf-8 ClientCharset big5

這樣一來就完成 FreeBSD UTF-8 化

vim + Ruby on rails

最近在 FreeBSD 上裝了 Ruby on Rails 因此把 Vim 裝起來 , 嗯 ~ 有了 Vim 之後看 Code 果然清楚多了 ~

1. 安裝 vim6+ruby , 不裝 X Windows 所以下 -DWITHOUT_X11。

#cd /usr/ports/editors/vim/
#make -DWITHOUT_X11 install clean

2. Copy Vim 設定檔 .vimrc 到使用者家目錄並且加入中文環境及自己所需要的設定。

#cp /usr/local/share/vim/vim64/vimrc_example.vim ~/.vimrc
#vi ~/.vimrc

set fileencoding=taiwan
set guifontset=8x16,kc15f,-*-16-*-big5-0
set cindent
set enc=taiwan
set fileencoding=taiwan
set hls
set nocompatible
set sw=2
set background=dark
set nomodeline
syntax on
highlight Comment ctermfg=darkcyan "更改Comment顏色
highlight Search term=reverse ctermbg=4 ctermfg=7

3. 原本的 vi 還是存在 , 若要使用 Vim 只要使用 vim 開啟檔便可。

放置rails.vim於/home/user/.vim/plugin/下

ports用portsnap較快

對於Release版的security patch可以用freebsd-update來做更新
http://ohaha.ks.edu.tw/post/1/32
The freebsd-update(8) utility supports binary upgrades of i386 and amd64 systems running earlier FreeBSD releases. Systems running 7.0-RELEASE, 7.1-BETA, 7.1-BETA2, 7.1-RC1, or 7.1-RC2 can upgrade as follows:
# freebsd-update upgrade -r 7.1-RELEASE
During this process, FreeBSD Update may ask the user to help by merging some configuration files or by confirming that the automatically performed merging was done correctly.
# freebsd-update install
The system must be rebooted with the newly installed kernel before continuing.
# shutdown -r now
After rebooting, freebsd-update needs to be run again to install the new userland components, and the system needs to be rebooted again:
# freebsd-update install
# shutdown -r now
自動安裝官方已經compile好的binary

cisco nat note

基本上在Cisco Router上的NAT有三種，但透過這三種NAT，又可以變化出LoadBalance等數種技巧基本的三種NAT方式：

Static NAT：靜態NAT轉址，直接指定每個內部Private IP其對外Public IP，固定為1對1的方式。但這種方法，依然需要大量的外部真實IP供給內部IP連線使用，沒有達到節省IP的目的，已少人使用。

Dynamic NAT：動態NAT轉址，訂定一到數個NAT Pool，指定可用來做為NAT轉址所用的Public IP之集合，供給內部Private IP動態轉址使用。每一次Private IP的連線，Router會輪流分派一個Public IP對外連線使用。

PAT(Port Address Translation):埠號地址轉換，是NAT的另一種加強型的技術，它可以允許許多個內部Private IP轉換到單一的Public IP。

也可以用interface ip overload。

Private IP的可用位址：RFC1918設定了三塊區域的私人IP位址，一般都是以這三個區塊當作NAT轉址的內部IP。這些IP並不會在Internet的路由間繞送。

Addr Range IP & mask

10.0.0.0 - 10.255.255.255 10.0.0.0/255.0.0.0 1個Class A

172.16.0.0 - 172.31.255.255 172.16.0.0/255.240.0.0 12個Class B

192.168.0.0 - 192.168.255.255 192.168.0.0/255.255.255.0 16個Class C

設定範例：

1.Static NAT，一個簡單的範例，將內部192.168.1.100 /24 的IP轉址成外部200.1.1.1 /24

Router1#conf t

Router1(config)#int S 0/0/0

Router1(config-if)#ip address 200.1.1.1 255.255.255.0

Router1(config-if)#ip nat outside

Router1(config-if)#no shutdown

Router1(config-if)#exit

Router1(config)#int fa 0/1

Router1(config-if)#ip address 192.168.1.254 255.255.255.0

Router1(config-if)#ip nat inside

Router1(config-if)#no shutdown

Router1(config-if)#exit

Router1(config)#ip nat inside source static 192.168.1.100 200.1.1.1

2.Dynamic NAT，定義一個連線集合(200.1.1.1~200.1.1.10)/24給內部192.168.1.1/24連線使用

Router1#conf t

Router1(config)#int S 0/0/0

Router1(config-if)#ip address 200.1.1.1 255.255.255.0

Router1(config-if)#ip nat outside

Router1(config-if)#no shutdown

Router1(config-if)#exit

Router1(config)#int fa 0/1

Router1(config-if)#ip address 192.168.1.254 255.255.255.0

Router1(config-if)#ip nat inside

Router1(config-if)#no shutdown

Router1(config-if)#exit

Router1(config)#ip nat pool nat1 200.1.1.1 200.1.1.10 netmask 255.255.255.0

Router1(config)#access-list 1 permit 10.1.1.0 0.0.0.255

Router1(config)#ip nat inside source list 1 pool nat1

Router1(config)#exit

3.PAT(Overload)，只定義一個IP提供NAT連線(200.1.1.1)/24給內部192.168.1.1/24連線使用

Router1#conf t

Router1(config)#int S 0/0/0

Router1(config-if)#ip address 200.1.1.1 255.255.255.0

Router1(config-if)#ip nat outside

Router1(config-if)#no shutdown

Router1(config-if)#exit

Router1(config)#int fa 0/1

Router1(config-if)#ip address 192.168.1.254 255.255.255.0

Router1(config-if)#ip nat inside

Router1(config-if)#no shutdown

Router1(config-if)#exit

Router1(config)#ip nat pool nat1 200.1.1.1 200.1.1.1 netmask 255.255.255.0

Router1(config)#access-list 1 permit 10.1.1.0 0.0.0.255

Router1(config)#ip nat inside source list 1 pool nat1 overload

Router1(config)#exit
