Always listen port 80

Postby juampa » 06. September 2010 22:17

Hello, I've installed XAMPP today (xampp-linux-1.7.3a) on Ubuntu 8.10. I made some changes and still don't understand why apache listen on Port 80:

httpd.conf
Code: Select all
#Listen 80
Listen 8000
NameVirtualHost localhost:85
NameVirtualHost localhost:8000

<VirtualHost localhost:85>
   ServerName localhost1
   DocumentRoot "/opt/lampp/htdocs"
</VirtualHost>

<VirtualHost localhost:8000>
   ServerName localhost2
   DocumentRoot "/opt/lampp/htdocs/dominio-8000"
</VirtualHost>


I atach two images:
1) The first shows opened ports, you can see both 80 and 8000. Why 80?!! Of course port 85 wasn't opened because <VirtualHost localhost:85> doesn't tell Apache which port open (that instruction is given by Listen, yes/no?)
2) The second shows all ports related to XAMPP closed.

Is Port 80 always opened when XAMPP start Apache?
There exists another config file? OBS: I comment all lines of httpd-vhosts.conf too.

Thanks in advance and sorry my English please.

Two things:

A - read this carefully and you will see you missed soemthing -

http://httpd.apache.org/docs/current/mo ... tml#listen

B - 'Open' means 'free' or 'avaialable' - not 'active' in this sense. 'listen' means the port is 'active' (the port is lsitening for activity)

When the operating system reports a port is open, it really means that the port is currently available to be assigned. When a port is assigned to a program, the port said to be 'listening for activity'.

Software utility programmes for port checking report the services commonly associated to each port number for ease of reference. The fact a service is listed only means that is a 'well known port'

Cuando el sistema operativo informes un puerto está abierto, lo que realmente significa que el puerto está actualmente disponible para ser asignado. Cuando un puerto está asignado a un programa, el puerto se dice que «la escucha de actividad».

Programas informáticos de utilidad para el control de puertos informe de los servicios comúnmente asociadas a cada número de puerto para facilitar su consulta. El hecho está en la lista de un servicio sólo significa que es un "puerto conocido"

Buena suerte con su proyecto
