Apache, default website

I found out that many has problems gettin default website to work when using virtualmin.

I found that the default website is workin for 127.0.0.1 but not for any other IP adress that you have to the box... is there anybody that has found out how to make this work?

you need to provide more information, such as OS and virtualmin versions, domain name etc
how did you install ?

I would suspect its an installation issue somehow, or perhaps DNS problem ?

this problem I have had for all versions of virtualmin (GPL).
and all versions of SuSE (from 9.x until 11.1 that is now the newest) I have tried.

MY DNS is working. the problem is ther when I ask for anything else than the requested domains it always replies with the first webserver defined in virtualmin. unless I type in adress 127.0.0.1 localy on the server, if I request the interface (eth0) I always get the first defined domain

and the error wasn't there before I set up the first virtual domain on virtualmin.

That may be because the default VirtualHost setup in your distro us setup using something like this:

[code:1]<VirtualHost *>[/code:1]

Rather than this:

[code:1]VirtualHost x.y.z.q:80[/code:1]

Where x.y.z.q is your servers IP address.

If there's a * in there, it will really confuse things and cause the behaviour you've been seeing.

That's part of the Apache config -- I'm not sure where Suse stores it, but perhaps something like /etc/httpd/conf/httpd.conf.

Joe, that was the place I checked, and it didn't tell me how to fix it

Apache does not have a "default" website when in virtual hosting mode. You're expecting behavior that doesn't exist. Labeling something "default" doesn't make it a "default".

When Apache is in virtual hosting mode, it serves the first-best match for the request. You can make a site be more "first" by moving it to the top of the list of VirtualHost sections.

And, if you have any * VirtualHost sections, they will make the behavior so hard to predict as to be pointless to try to figure out (if you think really long and hard about it, you might come to understand how Apache is making decisions, but I don't think it's worth the effort).

I don't see any errors mentioned in this thread. If you see an error and don't tell us what it is and what you see in the logs, how can we possibly help?

why does the default reply when I use adress 127.0.0.1?

I've already explained that in virtual hosting mode, Apache serves the first-best match. A "default", as you have configured, is never the best match when you have virtual hosts on the public IP addresses, so something else will always suck up the requests.

This is Apache behaving exactly as documented.

mmoxnes

that doesn't explain why it works on 127.0.0.1 but not for 192.168.1.2

is there any difference in those 2? as far as I understand from what you say I should get the same response for both ipadresses.. or am I mistaking

There is no difference in those two IP addresses to Apache. But you're still not grasping what I'm trying to explain to you.

Apache, when in virtual hosting mode, serves the first best match based on name and IP. One 192.168.1.2, you have other first-best matches. One 127.0.0.1, you have no first best match, so it falls all the way through to the "default".

If you'll just stop expecting "default" to have any meaning in a virtual hosting Apache configuration, you will find your life is a lot simpler. Once you have a virtual host on an IP address, "default" has <i>no meaning</i> to Apache (at least no useful meaning).

Re-read everything I've already written. I'm running out of ways to say the same thing. You're expecting Apache to work in ways that it does not, and is not documented to work.

To repeat myself (even more):

If you want a "default" site, you need to create a VirtualHost, and make sure it is first in the list of virtual servers.

You cannot expect your non-VirtualHost configured "default" site to ever be the first-best match when there are VirtualHosts on the same IP. It just isn't and never will be. That's not the way Apache works.

Thanks now I got it, and actually I understand what you meant this time.
so again thanks for being patient with me :)

thx for the answer.
the configfil for default server is:

#
# The directives in this section set up the values used by the 'main'

### Virtual server configuration ############################################
#
# VirtualHost: If you want to maintain multiple domains/hostnames on your
# machine you can setup VirtualHost containers for them. Most configurations
# use only name-based virtual hosts so the server doesn't need to worry about
# IP addresses. This is indicated by the asterisks in the directives below.
#
# Please see the documentation at
# <URL:http://httpd.apache.org/docs-2.2/vhosts/>
# for further details before you try to setup virtual hosts.
#
# You may use the command line option '-S' to verify your virtual host
# configuration.
#
Include /etc/apache2/vhosts.d/*.conf

# Note: instead of adding your own configuration here, consider
# adding it in your own file (/etc/apache2/httpd.conf.local)
# putting its name into APACHE_CONF_INCLUDE_FILES in
# /etc/sysconfig/apache2 -- this will make system updates
# easier :)
