hello every1 !
i m trying to set a webserver with virtualhost support , i used many tutorials as example to do this , but finally nothing successful
here are the steps i followed :

1) i created a new subdomaine called : web.wilaw.com
and link it to the apache machin's IP
2) install apache/php/SQLserver ( with apt-get )
i changed this lines on /etc/apache/httpd.conf :
*** LoadModules vhost_alias_module
*** NameVirtualHost 82.23.102.33 ( public IP)

here is my complete httpd.conf

after restarting apache , i was able to get the main /var/www/index.htm when using the server's IP in a browser , but when taping
subdomaine.mydomaine.net , nothing happen even if i see at the bottom of the page the IP of this server ( the DNS works )
###############################################
can someone help me on this please !

get rid off the http:// in your servername and try it again.
After edit the httpd.conf file restart apache with /etc/init.d/apache restart or apachectl graceful

Good Luck

i did this => no success anymore
well i remarque that when trying to open the remote site ftom the dns server which already ping ip i got :

Looking up web.wilaw.com first
Looking up web.wilaw.com
web.wilaw.com
Making HTTP connection web.wilaw.com
Alert!: Unable to connect to remote host.
soubds like the machine is down !
no i got an idea i ll try to look around : Listen
lynx: Can't access startfile http://web.wilaw.com/

ToBeContinued();

is apache running and if so look at its log files the one from your virtual host and the one from the basic apache ?

Can you telnet to the machine on port 80
# telnet ipadres 80
if so then
# telnet hostname 80

is there a index.html file in /var/www/test/ and is it readable for the apache user or group, www-data in your case

I found the pb finaly
was so stupide from my self , i just used a wrong IP addresse for the subdomaine , that's all !!!!
anyway ,, thank u for all ur answers
