tcp 0 0 server1.xxx:www *:* LISTEN 32034/apache
The hostname is server1.xxx.com
I've checked the apache error log, but there aren't errors related with this (just some "File does not exist: /var/www/sharedip/search.php", etc)
I've also checked apache config (httpd.conf), dind't found nothing strange (for example "ServerName localhost")
If it helps Apache is version 1.3.33 using ispconfig 2.2.13.
