bellagio — Thu, 13 Nov 2008 00:32:19 GMT

Reference: SuppressDefaultFTPBanner Metabase Property (IIS 6.0)

By default, the FTP service sends a "220 Microsoft FTP Service" banner when clients connect to the server. The SuppressDefaultFTPBanner property allows you to disable the display of the default FTP banner.

When SuppressDefaultFTPBanner is set to true, the message sent to the client will only include the number "220", not the "Microsoft FTP Service" part of the banner name. ...

UTF-8과 Euc-kr 동시에 사용하기

우선 이 기술문서는 서버관리자(루트)의 권한에서 선행되어야 함을 알려드립니다. 또한 Apache 2.xx , MySQL 4.1 이상의 UTF-8 기본 환경에서의 인코딩 문제로 충돌을 일으키는 분들에 대한 팁입니다.

echo "AddDefaultCharset euc-kr"

이 처럼 해당 계정에 .htaccess 로 임의지정 하여 사용하셔도 되지만 핫엑세스를 적용하기 전 데이터가 날아가는 현상이 일어납니다. 또한 AddDefaultCharset 옵션은 아파치 옵션이므로 본 옵션으로 인해 열린 html 파일이나 php 파일의 데이터 처리과정까지 영향을 주지 않습니다.

MySQL 설정파일 my.cnf의 [mysqld] 항목에

init_connect=SET NAMES binary
default-character-set=utf8

위와 같은 옵션을 My-SQL에 적용시켜 주면 기본 캐릭터셋은 UTF-8 이지만, 바이너리 모드로 등록이 되어 있기에 UTF-8과 EUC-kr을 동시에 사용하실 수 있습니다. 또한 아파치 환경설정에서

AddDefaultCharset utf8

항목을

AddDefaultCharset off

로 해주시면 인코딩과 상관없이 자동설정이 되게 하실 수 있습니다. 이와 같은 설정이 활성화 되면 제로보드4의 경우 UTF-8로 인코딩 작업을 하실 필요가 없어집니다.

Apache http : Protect Server Files by Default

To forbid default access to filesystem locations, add the following,

Order Deny,Allow Deny from all

And, add appropriate directorys to allow access only in those areas you wish.

For example,

Order Deny,Allow Allow from all Order Deny,Allow Allow from all
