Arborescence web inaccessible

[Le_Farfadet_Spatial]

Salut à tous !

J’ai une vraie catastrophe sur mon serveur. J’ai l’arborescence suivante :

$ ls /var/www/yoann/
repos

Et dans le répertoire « repos » se trouve plusieurs dépôts Darcs :

$ ls /var/www/yoann/repos/
livre-C++  MIT-2010

Malheureusement, si le domaine reste accessible (vous pouvez le vérifier en allant sur http://le-bars.net/), il n’est désormais plus possible d’accéder à http://le-bars.net/yoann/, ni à ses sous-répertoires – essayez, vous allez voir.

Je bricole pas mal en ce moment pour essayer d’installer OBM, du coup j’ai sans doute cassé quelque chose, mais je ne sais pas quoi et je ne sais pas comment faire un diagnostic. En plus, j’ai des échéances prochaines, j’ai vraiment besoin que ces dépôts soient accessibles.

En tout cas, Apache est toujours installé :

$ dpkg -l | grep apache
ii  apache2                              2.2.9-10+lenny8            Apache HTTP Server metapackage
ii  apache2-doc                          2.2.9-10+lenny8            Apache HTTP Server documentation

ii  apache2-utils                        2.2.9-10+lenny8            utility programs for webservers
ii  apache2.2-common                     2.2.9-10+lenny8            Apache HTTP Server common files
ii  libapache2-mod-perl2                 2.0.4-5+lenny1             Integration of perl with the Apache2 web server
ii  libapache2-mod-php5                  5.2.6.dfsg.1-1+lenny8      server-side, HTML-embedded scripting language (Apache 2 module
ii  libapache2-mod-python                3.3.1-7                    Python-embedding module for Apache 2

Donc, pour le coup, j’ai un vrai appel au-secours : quelqu’un a-t-il une idée, parce qu’il faut que je règle ce problème de toute urgence et je n’ai pas le moindre début de piste sur ce que je dois faire.

À bientôt.

Et la config d’apache au niveau des vhosts et hosts ca donne quoi ?

[Le_Farfadet_Spatial]

Salut à tous !

Je dois dire que c’est le premier serveur Apache que je gère, je suis encore un peu hésitant.

Et la config d’apache au niveau des vhosts et hosts ca donne quoi ?

Je ne sais pas bien, que penses-tu de ça :

$ cat /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>

#
# 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

#
# 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

#
# 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 "%v:%p %h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" vhost_combined
LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined

LogFormat "%{User-agent}i" agent

#
# Define an access log for VirtualHosts that don't define their own logfile
CustomLog /var/log/apache2/other_vhosts_access.log vhost_combined

#
# 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.

Salut à tous !

Non, ce qu’on me demande, c’est ce qui se trouve dans le répertoire « /etc/apache2/sites-available/ » :

N’y-aurait-il pas comme une incompatibilité entre les deux ? En tout cas, il manque « default » dans « /etc/apache2/sites-enabled/ » :

$ sudo /etc/init.d/apache2 restart
Restarting web server: apache2[Wed Aug 04 00:22:57 2010] [warn] _default_ VirtualHost overlap on port 80, the first has precedence

[Wed Aug 04 00:22:57 2010] [warn] _default_ VirtualHost overlap on port 80, the first has precedence
[Wed Aug 04 00:22:57 2010] [warn] NameVirtualHost *:443 has no VirtualHosts
 failed!

Bon sang ! C’est bien là le problème : l’un gène l’autre. Bon, maintenant, la question : comment puis-je régler ce problème ? Je tente :

$ sudo a2dissite obm 
Site obm disabled.
Run '/etc/init.d/apache2 reload' to activate new configuration!
$ sudo a2ensite default
Enabling site default.
Run '/etc/init.d/apache2 reload' to activate new configuration!
$ sudo /etc/init.d/apache2 reload
Reloading web server config: apache2

Cependant, aucun effet : la partie « le-bars.net/yoann/ » est toujours inaccessible. Pour l’instant, je sèche.

Si quelqu’un a une idée, surtout qu’il n’hésite pas, parce que j’ai une très forte pression pour réparer tout cela très vite (de toute urgence pour avant hier) et je suis complètement dans le flou.

À bientôt.

Salut à tous !

Je commence à avoir des doutes concernant le fournisseur d’accès, qui pourrait bien bloquer le trafic.

Je me pose maintenant les questions suivantes : est-ce que quelqu’un connaît une méthode pour déterminer si le fournisseur d’accès bloque les protocoles HTTP, HTTPS, FTP, SFTP et NEWS en sortie ? Que donne le domaine le-bars.dyndns.org chez vous – ping, HTTP, ce qui vous passe par la tête ?

À bientôt.

Le Farfadet Spatial

[Mimoza]

Quel est ton FAI/hébergeur ?
De mon coté ton site ou dydns ne fonctionne pas.

[Le_Farfadet_Spatial]

Salut à tous !

Je pense qu’il n’y a plus guère de doute : je crois bien que le fournisseur d’accès effectue un blocage :

$ nmap le-bars.net

Starting Nmap 5.00 ( http://nmap.org ) at 2010-08-05 08:27 CEST
Note: Host seems down. If it is really up, but blocking our ping probes, try -PN
Nmap done: 1 IP address (0 hosts up) scanned in 3.14 seconds

$ nmap le-bars.dyndns.org

Starting Nmap 5.00 ( http://nmap.org ) at 2010-08-05 08:27 CEST
Interesting ports on ip-215.net-81-220-100.nantes.rev.numericable.fr (81.220.100.215):
Not shown: 995 filtered ports
PORT    STATE  SERVICE
21/tcp  closed ftp
22/tcp  open   ssh
80/tcp  closed http
144/tcp closed news
443/tcp closed https

Nmap done: 1 IP address (1 host up) scanned in 5.94 seconds

Donc, en dépit du fait que je fais exécuter DynHost toutes les heures par Cron, actuellement le-bars.net ne pointe plus sur une IP valide. De plus, personnellement, je n’ai pas fermé les ports indiqués. Je suis en train de voir pour changer de fournisseur d’accès.

À bientôt.
