Bad Gateway errors generally come from proxies... so I would guess that
your domain
is not yet visable by the proxy involved.. this would explain most of
your issues!!

Hi All,
    I am having a problem getting a website working on a server. I have
RTFMed, and this has shed no light on the problem and since this is the
first time I have tried to set up Apache, I need a little help.
Basically the problem goes like this:

    I have set up an IP alias on my system and given it the
IP address I want to use for this web site (ie. my server is
203.myIP.193 on eth0:0, and the alias is 203.myIP.250 on eth0:1). These
are correct, visible and pingable etc.

    I have set up DNS with my name servers for this IP
address and delegated the new domain and it is visible on
the net (ie www.mydomain and www.mynewdomain are visible
using DNS diagnostic tools Telstra provide with their DNS services).

I have a series of web pages set up and they are live on the net (ie I
can get people outside my network to see them).

    This is where the problem starts.

If I type in www.mydomain I get:

Bad Gateway
The following error occurred:

A DNS lookup error occurred. The host was not found.

This was working before I started this project.


If I type in www.mynewdomain I get:

Bad Gateway
The following error occurred:

A DNS lookup error occurred. The host was not found.

This is what I want to get working.


If I type in http://203.myIP.193 I get the index page for my site
www.mydomain

If I type in http://203.myIP.250 I get the index page for my site
www.mydomain


But here is another weird part -

The new web site hangs off the default html directory (which
is /var/www/html/) in a sub-directory that is visible by
typing in http://203.myIP.193/subdir/index.html (as you
would expect).

If I type in http://203.myIP.250/index.html I get the index page for my
site www.mynewdomain , which is in /var/www/html/subdir/index.html.

Here are the two things that are puzzling me:

1.Why does Apache think DNS isn't working when I can get it
to work manually using the normal tools (ping, nslookup, whois)? BTW my
mail and everything else on the server isn't broken.

2. Why does http://203.myIP.250 get the index page of the default html
directory just like http://203.myIP.193 (my server and this is the
behaviour I would expect) but if I type in
http://203.myIP.250/index.html gets the index page to the new website,
which is hanging off the default html directory in a sub-directory?
Logically these two pages are the same since the default html file is
/var/www/html/index.html.

O.K. here are a few diagnostic tidbits.

The server runs RH7.0 and Apache 1.3.13

The logs are a bit hard to interpret, but seem fine
(access_log and error_log and newaccess_log newerror_log)

httpd.conf
Has HostNameLookups On, but this doesn't seem to make any difference if
it is Off

Has two Virtual hosts set up
NameVirtualHost 203.myIP.193
NameVirtualHost 203.myIP.250
and
<VirtualHost 203.myIP.193>
  ServerName www.mydomain
  DocumentRoot /var/www/html/
</VirtualHost>

<VirtualHost 203.myIP.250>
  DocumentRoot /var/www/html/subdir/
  ServerName www.mynewdomain

  ErrorLog logs/newerror_log
  CustomLog logs/newaccess_log common
</VirtualHost>


What I want in the end to be able to do is type in
www.mydomain and get the index page for mydomain and type in
www.mynewdomain and get the index page for mynewdomain. This has been
annoying me for over a week now, and I am sure that it is a simple
problem to fix, but my limited experience with Apache is probably
blinding me to the answer. If anyone could assist that would be most
appreciated as I needed to get this site working a couple of weeks ago
and it still isn't. Thanks in advance.
    Cheers!
        Andrew.
