View Full Version : [ubuntu] [SOLVED] Server setup and configuration issues

Hello,
Sorry for my initial ignorance, I am never setup a website before. I am attempting to use apache2 on ubuntu to host a website.
I have installed everything, and signed up at dyndns.org (I can SSH using dyndns.org fine).
On my server, I can access my default page by using any of the following:
http://localhost/
http://127.0.1.1/
http://192.168.0.2/ (its permanent IP on my network).

However I cannot access http://192.168.0.2 from the browser of any other computer on my network. I will get a "The server at 192.168.0.2 is taking too long to respond" error. I have forwarded port 80 in my router.
Here are the contents of my configuration files.
Any help would be appreciated, I'm sure its an easy fix for someone who knows what they are doing.
Thanks.

/etc/apache2/ports.conf

Listen 80

<IfModule mod_ssl.c>
Listen 443
</IfModule>

/etc/apache2/httpd.conf is empty

/etc/apache2/conf.d/fqdn

ServerName localhost


/etc/apache2/apache2.conf

#
# Based upon the NCSA server configuration files originally by Rob McCool.
#
# This is the main Apache server configuration file. It contains the
# configuration directives that give the server its instructions.
# See http://httpd.apache.org/docs/2.2/ for detailed information about
# the directives.
#
# Do NOT simply read the instructions in here without understanding
# what they do. They're here only as hints or reminders. If you are unsure
# consult the online docs. You have been warned.
#
# The configuration directives are grouped into three basic sections:
# 1. Directives that control the operation of the Apache server process as a
# whole (the 'global environment').
# 2. Directives that define the parameters of the 'main' or 'default' server,
# which responds to requests that aren't handled by a virtual host.
# These directives also provide default values for the settings
# of all virtual hosts.
# 3. Settings for virtual hosts, which allow Web requests to be sent to
# different IP addresses or hostnames and have them handled by the
# same Apache server process.
#
# Configuration and logfile names: If the filenames you specify for many
# of the server's control files begin with "/" (or "drive:/" for Win32), the
# server will use that explicit path. If the filenames do *not* begin
# with "/", the value of ServerRoot is prepended -- so "/var/log/apache2/foo.log"
# with ServerRoot set to "" will be interpreted by the
# server as "//var/log/apache2/foo.log".
#

### Section 1: Global Environment
#
# The directives in this section affect the overall operation of Apache,
# such as the number of concurrent requests it can handle or where it
# can find its configuration files.
#

#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# NOTE! If you intend to place this on an NFS (or otherwise network)
# mounted filesystem then please read the LockFile documentation (available
# at <URL:http://httpd.apache.org/docs-2.1/mod/mpm_common.html#lockfile>);
# you will save yourself a lot of trouble.
#
# Do NOT add a slash at the end of the directory path.
#
ServerRoot "/etc/apache2"

#
# The accept serialization lock file MUST BE STORED ON A LOCAL DISK.
#
#<IfModule !mpm_winnt.c>
#<IfModule !mpm_netware.c>
LockFile /var/lock/apache2/accept.lock
#</IfModule>
#</IfModule>

#
# PidFile: The file in which the server should record its process
# identification number when it starts.
# This needs to be set in /etc/apache2/envvars
#
PidFile ${APACHE_PID_FILE}

#
# Timeout: The number of seconds before receives and sends time out.
#
Timeout 300

#
# KeepAlive: Whether or not to allow persistent connections (more than
# one request per connection). Set to "Off" to deactivate.
#
KeepAlive On

#
# MaxKeepAliveRequests: The maximum number of requests to allow
# during a persistent connection. Set to 0 to allow an unlimited amount.
# We recommend you leave this number high, for maximum performance.
#
MaxKeepAliveRequests 100

#
# KeepAliveTimeout: Number of seconds to wait for the next request from the
# same client on the same connection.
#
KeepAliveTimeout 15

# prefork MPM
# StartServers: number of server processes to start
# MinSpareServers: minimum number of server processes which are kept spare
# MaxSpareServers: maximum number of server processes which are kept spare

#
# AccessFileName: The name of the file to look for in each directory
# for additional configuration directives. See also the AllowOverride
# directive.

# The following lines prevent .htaccess and .htpasswd files from being
# viewed by Web clients.

</Files>

#
# DefaultType is the default MIME type the server will use for a document
# if it cannot otherwise determine one, such as from filename extensions.
# If your server contains mostly text or HTML documents, "text/plain" is
# a good value. If most of your content is binary, such as applications
# or images, you may want to use "application/octet-stream" instead to
# keep browsers from trying to display binary files as though they are
# text.
#
DefaultType text/plain


#
# HostnameLookups: Log the names of clients or just their IP addresses
# e.g., www.apache.org (on) or 204.62.129.132 (off).
# The default is off because it'd be overall better for the net if people
# had to knowingly turn this feature on, since enabling it means that
# each client request will result in AT LEAST one lookup request to the
# nameserver.
#
HostnameLookups Off

# ErrorLog: The location of the error log file.
# If you do not specify an ErrorLog directive within a <VirtualHost>
# container, error messages relating to that virtual host will be
# logged here. If you *do* define an error logfile for a <VirtualHost>
# container, that host's errors will be logged there and not here.
#
ErrorLog /var/log/apache2/error.log

#
# LogLevel: Control the number of messages logged to the error_log.
# Possible values include: debug, info, notice, warn, error, crit,
# alert, emerg.
#
LogLevel warn

# Include module configuration:
Include /etc/apache2/mods-enabled/*.load
Include /etc/apache2/mods-enabled/*.conf

# Include all the user configurations:
Include /etc/apache2/httpd.conf

# Include ports listing
Include /etc/apache2/ports.conf

#
# The following directives define some format nicknames for use with
# a CustomLog directive (see below).
# If you are behind a reverse proxy, you might want to change %h into %{X-Forwarded-For}i
#
LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined
LogFormat "%h %l %u %t \"%r\" %>s %b" common
LogFormat "%{Referer}i -> %U" referer
LogFormat "%{User-agent}i" agent

#
# ServerTokens
# This directive configures what you return as the Server HTTP response
# Header. The default is 'Full' which sends information about the OS-Type
# and compiled in modules.
# Set to one of: Full | OS | Minor | Minimal | Major | Prod
# where Full conveys the most information, and Prod the least.
#
ServerTokens Full

#
# Optionally add a line containing the server version and virtual host
# name to server-generated pages (internal error documents, FTP directory
# listings, mod_status and mod_info output etc., but not CGI generated
# documents or custom error documents).
# Set to "EMail" to also include a mailto: link to the ServerAdmin.
# Set to one of: On | Off | EMail
#
ServerSignature On



#
# Customizable error responses come in three flavors:
# 1) plain text 2) local redirects 3) external redirects
#
# Some examples:
#ErrorDocument 500 "The server made a boo boo."
#ErrorDocument 404 /missing.html
#ErrorDocument 404 "/cgi-bin/missing_handler.pl"
#ErrorDocument 402 http://www.example.com/subscription_info.html
#

#
# Putting this all together, we can internationalize error responses.
#
# We use Alias to redirect any /error/HTTP_<error>.html.var response to
# our collection of by-error message multi-language collections. We use
# includes to substitute the appropriate text.
#
# You can modify the messages' appearance without changing any of the
# default HTTP_<error>.html.var files by adding the line:
#
# Alias /error/include/ "/your/include/path/"
#
# which allows you to create your own set of files by starting with the
# /usr/share/apache2/error/include/ files and copying them to /your/include/path/,
# even on a per-VirtualHost basis. The default include files will display
# your Apache version number and your ServerAdmin email address regardless
# of the setting of ServerSignature.
#
# The internationalized error documents require mod_alias, mod_include
# and mod_negotiation. To activate them, uncomment the following 30 lines.

# Alias /error/ "/usr/share/apache2/error/"
#
# <Directory "/usr/share/apache2/error">
# AllowOverride None
# Options IncludesNoExec

Change ServerName to 192.168.0.2
localhost is the same as 127.0.0.1 which is a loopback address and means Apache is not available from external computers.

Thanks, I have changed that now, but I still get "server took too long to respond" error from other computers on the network.

Any other suggestions?

Are you running any firewall?

Davit001
August 21st, 2008, 08:59 PM
I have no firewall on the ubuntu server, have the ports forwarded on the router, and the firewall on the computer attempting to connect disabled.
So I don't think there is any firewall left in the way.
Thanks for the suggestion, anything else jump to mind?

Can you post your /etc/hosts file?

Davit001

Here it is:

/etc$ cat hosts
127.0.0.1 localhost
127.0.1.1 davelaptop1

# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

Hmm. Can you try to telnet to it on port 80 from another machine?

telnet 192.168.0.2 80

If you can, type the following once it connects:

GET / HTTP/1.1
host: 192.168.0.2




(After the last line, hit return twice.)

You've probably already done this - clients can ping server?

telnet 192.168.0.2 80
Connecting To 192.168.0.2...Could not open connection to the host, on port 80: Connect failed

I can ping it fine (so its the right IP) and I can SSH in fine as well.

Ok, so it sounds like it's not a network problem. Did you make any custom configurations after the install, or is this just a default install?

I just installed apache2, php, and mysql. I haven't made any changes to the default config files, so everything is still default. I found other threads of people having trouble connecting from outside their network, but none having problems connecting inside the network as I am.
Thanks for your continued help.

Try changing 80 to 8080 in /etc/apache2/ports.conf then restart apache, then go to 192.168.0.2:8080 from another networked computer.

That got it, thank god.
Must have had an issue blocking port 80. I thought I had tried that earlier but apparently not!
Thanks for your time guywithcable and everyone else who helped.

Thanks again.

PS I thought I was the only one who remembered Sonic Underground :)
