Question

[TANK_IST]

Есть сайт site.net.
Нужно создать копию сайта на dev.site.net.

pachectl -S
VirtualHost configuration:
*:80                   is a NameVirtualHost
         default server dev.locations-vacances-particuliers.com (/etc/apache2/sites-enabled/devlocationsvacancesparticuliers.conf:1)
         port 80 namevhost dev.locations-vacances-particuliers.com (/etc/apache2/sites-enabled/devlocationsvacancesparticuliers.conf:1)
                 alias www.dev.locations-vacances-particuliers.com
         port 80 namevhost lemoulinvollach.com (/etc/apache2/sites-enabled/lemoulinvollach.conf:1)
                 alias www.lemoulinvollach.com
         port 80 namevhost locations-vacances-particuliers.com (/etc/apache2/sites-enabled/locationsvacancesparticuliers.conf:1)
                 alias www.locations-vacances-particuliers.com
         port 80 namevhost location-vacances-vista.com (/etc/apache2/sites-enabled/locationvacancesvista.conf:1)
                 alias www.location-vacances-vista.com
         port 80 namevhost villamenerbellec.com (/etc/apache2/sites-enabled/villamenerbellec.conf:1)
                 alias www.villamenerbellec.com

host dev.locations-vacances-particuliers.com
Host dev.locations-vacances-particuliers.com not found: 3(NXDOMAIN)

Конфиг в /etc/apache2/site-enabled прописал.

Спасибо!
