apache mod_access

我想用server-status
[url]http://xxx.twbbs.org/server-status[/url]
在status.conf

[code]
<Location /server-status>
SetHandler server-status
Order deny,allow
Deny from all
Allow from xxx.twbbs.org
</Location>
[/code]

可是我去連[url]http://xxx.twbbs.org/server-status[/url]
卻出現
[code]
Forbidden

You don't have permission to access /server-status on this server.
[/code]

但是將xxx.twbbs.org 改成 IP 就可以連的上
[code]
Allow from 123.123.123.123
[/code]

再去連[url]http://xxx.twbbs.org/server-status[/url]
就連的上
而xxx.twbbs.org 有對應到IP 123.123.123.123
因為 [COLOR="Blue"]ping xxx.twbbs.org[/COLOR]
[code]
PING xxx.twbbs.org (123.123.123.123)
64 bytes from.....
64 bytes from.....
64 bytes from.....
3 packets transmitted, 3 received, 0% packet loss, time 2007ms
[/code]

是Allow from 後面不能接domain name嗎
還是我那裡沒設好

[url]http://httpd.apache.org/docs/1.3/mod/mod_access.html#allow[/url]
[url]http://httpd.apache.org/docs/2.0/mod/mod_access.html#allow[/url]

[QUOTE=tvirus;1044287][url]http://httpd.apache.org/docs/1.3/mod/mod_access.html#allow[/url]
[url]http://httpd.apache.org/docs/2.0/mod/mod_access.html#allow[/url][/QUOTE]

有參考過了
不過還是不太明白哪裡出錯了...
能在多解釋一下嗎 ?
謝謝!!

HostnameLookups = Double

[COLOR="Blue"]你把123.123.123.123 xxx.twbbs.org 寫到/etc/hosts裡面試試看[/COLOR]
