apache2 won't connect to localhost or 127.0.0.1


Well, the above says it all, with the following two additional comments:

1. I use a cable modem with a specific IP address & a router with port 80 forwarded to my home Linux development machine. From outside my house (e. g., from my office), I can connect no problem.

2. My home development machine is IP 192.168.1.20- if I use this address in the browser (on the home development machine) it connects. However, on the same machine, neither localhost nor 127.0.0.1 connect.

Nothing shows up in the regular log (even with logging set to "debug"), but this shows up in the error log for both localhost and 127.0.0.1:
Quote:
[Mon Mar 16 19:05:28 2009] [error] [client 127.0.0.1] File does not exist: /htdocs
This is particularly odd, since I have NO reference to htdocs in any of my configuration files. I have grep'd all over the place, and the only reference that shows up is in the apache2 binary.

When I do 192.168.1.20, I get this in the error log:
Quote:
[Mon Mar 16 19:10:24 2009] [error] [client 192.168.1.20] File does not exist: /var/www/localhost/scripts, referer: http://192.168.1.20/
Which should be OK, because in this initial, very immature test environment, I don't have the /scripts directory defined; I don't think it has anything to do with my problem. I get the web page.

My sites-enabled/000-default (appropriately linked per convention to a file in sites-available) has been completely stripped down. I have exactly the same situation with the default sites-* file. Here's the minimal version:
Code:
NameVirtualHost *
<VirtualHost *>
    ServerName localhost
    DocumentRoot /var/www/localhost

    ErrorLog /var/log/apache2/error.log

    # Possible values include: debug, info, notice, warn, error, crit,
    # alert, emerg.
    LogLevel debug

    CustomLog /var/log/apache2/access.log combined
</VirtualHost>
My apache2.conf (Debian's apache2 config file, as opposed to httpd.conf) probably isn't the cause of this, but here it is. It is also plain vanilla, except I had to cut it back per this forum to make no bigger than 25000 characters.

#
# which allows you to create your own set of files by starting with the

the ip settings

I don't think this is related to the Apache webserver itself. It seems that you don't have your lo device set correctly. I don't know how did you set up your machine or what distro you're using ( if any ;-) ) but let's try this:
Code:
ip addr show
that should show all network devices you have and their settings. (using ifconfig is not recommended on 2.4 and 2.6 kernels).
You should see something like this:
Code:
lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
    inet6 ::1/128 scope host
If you that command notices you that the state is DOWN, then you're on the good way. To set up your lo device type this:

Code:
ip addr add 127.0.0.1 dev lo
ip link set lo up
I hope the first line is correct. That should set up other variables automatically.
That should work it out.

My loopback reports just as you indicated it should. Also, I can telnet and ping to both 127.0.0.1 and localhost.

Thanks!

2. My home development machine is IP 192.168.1.20- if I use this address in the browser (on the home development machine) it connects. However, on the same machine, neither localhost nor 127.0.0.1 connect.

Nothing shows up in the regular log (even with logging set to "debug"), but this shows up in the error log for both localhost and 127.0.0.1:
Quote:
[Mon Mar 16 19:05:28 2009] [error] [client 127.0.0.1] File does not exist: /htdocs
Actually from the error_log it seems that you connect to localhost but cannot find /htdocs. I don't use Debian but I think that maybe you have to use a2ensite to enable the localhost vhost and create the appropriate symlinks.

Thanks, but the sym links are set up correctly. Yes, it appears it can't find /htdocs, but why is it even looking for htdocs? The term "htdocs" appears nowhere in my configuration files.

Run
Code:
httpd -S
to see how your vhosts are configured.

Hey, I didn't know this command line option existed. Here's the output:
Quote:
apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName
VirtualHost configuration:
127.0.0.1:* localhost (/etc/apache2/conf.d/mod_jk.auto:16)
wildcard NameVirtualHosts and _default_ servers:
*:* is a NameVirtualHost
default server localhost (/etc/apache2/sites-enabled/000-default:2)
port * namevhost localhost (/etc/apache2/sites-enabled/000-default:2)
Syntax OK
It says a lot about localhost, but doesn't accept it in the browser. Do you know how to interpret this?

Thanks!

You can add
Code:
ServerName localhost
in httpd.conf to avoid the warning, even though it's better to use a real hostname like www.domain.com.
I suggest you to create another vhost file in sites-enabled (name it locahost or something), enable it, disable 000-default and see if it works

My virtual host configuration file is in my original post. As you can see, it has "ServerName localhost" in it.

You can add the ServerName directive in the main httpd.conf to get rid of the warning.
Anyway did you try to replace 000-default with another file and see what happens?

I'm not sure what you mean by "add the ServerName directive in the mail httpd.conf". What's "mail httpd.conf"? Yes, I've tried both the minimized version that I posted, as well as the default one that came with it.

Sorry about the typo. I mean main (the apache conf file). In the link I gave you it says that you have to add the "ServerName ..." in /etc/apache2/conf.d/local. But that is for the initial warning.
For the localhost problem you must review the files in sites-available and enable them using the Debian method.

Ah! Yes, the /etc/apache2/apache2.conf is the main configuration file in Debian, and I've enable the sites according to the docs, i. e., putting a soft link from a file in sites-enable to sites-available.

Hey, do you mean this error?
Quote:

Since I have "ServerName localhost" in the VirtualHost section, I don't see why I'm getting this. And don't know why I can't connect to localhost.

Thanks!

BTW, the message I get in the browser is:
Quote:
The requested URL / was not found on this server.
Again, I don't get this message when I use 192.168.1.20
