my machine is debian sarge 3.1
# uname -a
2.4.27-2-386

I would like to use virtual host in apache2,it is quiet diff w/ other version.

I did the following steps:-
-added my ip ...
-add ServerName...
-make a file /var/ww/dn1/index.html
-make symbolic link
-restart apache2

2)
/etc/apache2/sites-available# ls
default domain1
/etc/apache2/sites-available# cat domain1
----------
NameVirtualHost 203.x.x.x

ServerAdmin webmaster@localhost
ServerName www.domain1.com
DocumentRoot /var/www/dn1/

.
.
.

-----
cd /var/www/dn1# ls
index.html

-----
3) I make a file of domain1
dns:/etc/apache2/sites-available# ls
default domain1

4) create symbolic link
ln -s /etc/apache2/sites-available/domain1
/etc/apache2/sites-enabled/domain1.com

5)tail /var/log/apache2/error.log
[warn] NameVirtualHost 203.x.x.x. has no VirtualHosts

6) At client,
open a browser, and try to go http://www.domain1.com

Result:-
Not Found
The request URL / was not found on this server.

p.s. I have tried to find the answer in apache's manual for 2 weeks, but still couldn't find my need.

Thanks for any reply.
