mod_geoip2 Apache module

The mod_geoip2 module embeds GeoIP database lookups into the Apache web server. It is only capable of looking up the IP of a client that connects to the web server, as opposed to looking up arbitrary addresses.

This module works with Apache 2. Please use mod_geoip with Apache 1.

Installation

You may download the latest release of mod_geoip2 or get the latest development version from GitHub. See the included INSTALL file in the tarball for installation details.

Overview

The mod_geoip2 module uses the libGeoIP library to look up geolocation information for a client as part of the http request process. This module is free software, and is licensed under the Apache license.

To compile and install this module, you must first install libGeoIP 1.4.3 or newer.

The mod_geoip2 module takes effect either during request header parsing phase or the post read request phase, depending on whether it is configured for server-wide use or for a specific location/directory.

When enabled, the module looks at the incoming IP address and sets some variables which provide geolocation information for that IP. The variables it set depend on the specific GeoIP database being used (Country, City, ISP, etc.). These variables can be set in either the request notes table, the environment or both depending on the server configuration.

ISPConfig 3 + Squeeze – SSL/TLS 465 SMTP Fail

15/10/2018 Categories: Logiciel Tags: , Aucun commentaire

ispconfigSource: howtoforge.com

Hi there.

New install of ISPConfig 3 on Debian Squeeze [previously on Lenny]

Created using: http://www.ispconfig.org/news/tutorial-the-perfect-server-debian-squeeze-debian-6-0-with-bind-courier-ispconfig-3/

Previous server used:

Port: 465
Connection security: SSL/TLS
Authentication method: normal password

If I try to use these setting on this fresh install [complete format with previous back up files stored on a seperate drive] I get the following error:

Sending of message failed.

The message could not be sent because connecting to SMTP server mail.myserver.com (changed from real name – error has correct name) failed. The server may be unavailable or is refusing SMTP connections. Please verify that your SMTP server settings are correct and try again, or contact the server administrator.

I can send using:

Port: 25
Connection security: STARTTLS
Authentication method: normal password

No errors appear in mail.log or mail.err

I’ve compared the master.cf pre/post [original/current]

Differing section appears to be:

Original

smtp inet n - - - - smtpd
submission inet n - - - - smtpd
-o smtpd_tls_security_level=encrypt
-o smtpd_sasl_auth_enable=yes
-o smtpd_client_restrictions=permit_sasl_authenticate d,reject
-o milter_macro_daemon_name=ORIGINATING
smtps inet n - - - - smtpd
-o smtpd_tls_wrappermode=yes
-o smtpd_sasl_auth_enable=yes
-o smtpd_client_restrictions=permit_sasl_authenticate d,reject
-o milter_macro_daemon_name=ORIGINATING

Current

smtp inet n - - - - smtpd
#submission inet n - - - - smtpd
# -o smtpd_tls_security_level=encrypt
# -o smtpd_sasl_auth_enable=yes
# -o smtpd_client_restrictions=permit_sasl_authenticate d,reject
# -o milter_macro_daemon_name=ORIGINATING
#smtps inet n - - - - smtpd
# -o smtpd_tls_wrappermode=yes
# -o smtpd_sasl_auth_enable=yes
# -o smtpd_client_restrictions=permit_sasl_authenticate d,reject
# -o milter_macro_daemon_name=ORIGINATING

main.cf has a couple of minor differences

Original

smtpd_tls_CAfile = /etc/postfix/cert.pem

*This line is missing in the current main.cf

Current

smtpd_sasl_type = dovecot
smtpd_sasl_path = private/auth

*These lines do not appear in the original main.cf

No firewall rules are set to block ports.

hopefully I’ve provided enough detail.

Sauvegarder ses données avec Rsync

En parcourant pas mal de forums, j’ai pu remarquer que pas mal de jeunes admins ne connaissaient pas Rync.

Rsync est un petit outil de sauvegarde extrêmement puissant. Grâce à cette outil j’ai pu sauvegarder des centaines de  giga-octet de données sans problèmes.

Source: Upwards with SBS

In earlier blog posts I’ve discussed other DNS records such as the TXT SPF record.  This is a new but very important record that you will want in place for your domain.

Here’s a list of great resources that describe this in detail and include guidance to manually create and publish the record to whomever is hosting your DNS records for the domain.

Récupérer le zoom dans OS X Mountain Lion

14/10/2018 Categories: Logiciel Tags: , Aucun commentaire

La dernière mouture en date d’OSX désactive une fonction assez pratique : le zoom.

Son utilisation est possible sur les versions précédentes en maintenant la touche CTRL + scroll.

Pour la réactiver sous OSX Mountain Lion, il suffit d’aller dans les préférences :

  1. Préférences système…
  2. Accessibilité
  3. Réduite/agrandir

Il suffit ensuite de cocher « Pour effectuer un zoom, utilisez le geste de défilement avec les touches de modification : »
