To change the order of the accounts in Thunderbird simply edit
~/.thunderbird/<your profile>/prefs.js in GNU/Linux,C:\Documents and Settings\<your profile>\Application Data\Thunderbird\Profiles\****.default\prefs.js in Microsoft Windows XP,note: increasing PHP upload size is different from increasing PHP memory limit. You can learn to increase memory limit here.
Drupal’s limits on upload file size are determined by your server’s PHP settings (as well as Drupal specified settings that can be set at Admin > Site Configuration > File Upload). The default values for PHP will restrict you to a maximum 2 MB upload file size.
On the settings page for the upload module, Drupal calculates and displays the maximum file size that you can set based upon two PHP settings: ‘post_max_size’ and ‘upload_max_filesize’. Since ‘post_max_size’ is the limit for all the content of your post, many people choose ‘post_max_size’ to be a multiple of ‘upload_max_filesize’ to allow multiple files to be uploaded, but this is not essential. The upload module limits the size of a single attachment to be less than either post_max_size, or upload_max_filesize, whichever is smaller. The default PHP values are 2 MB for upload_max_filesize, and 8 MB for post_max_size.

Up until now i have been manually blocking ip’s that attack my server but by the time i see them the attacks have normally finished but after the last big attack on my email server (some 35,000 attempts) i decided to find a way to automate the blocking. After a bit of research i decided to setup Fail2ban and here’s how i did it.
As i use a 3rd party repostories – EPEL (how to add repositories) i can just use yum to install it
yum install fail2ban
once installed i just needed to change the configuration to my liking, the config files can be found at « /etc/fail2ban »
first i edit « /etc/fail2ban/fail2ban.conf » and ensure the « logtarget » is set correctly
logtarget = /var/log/fail2ban.log
The default behaviour of fail2ban is configured in the file « /etc/fail2ban/jail.conf ». There’s a [DEFAULT] section that applies to all other sections unless the default options are overridden in the other sections. Lire la suite…

Si vous cherchez un utilitaire et une bibliothèque pour vos projets qui permette d’afficher dans un terminal une image en utilisant du code ANSI, j’ai ce qu’il vous faut. Ça s’appelle Picture-tube et pour l’installer c’est très simple. Il vous faudra npm, donc sous ubuntu pour installer un petit npm, il faut taper :
sudo apt-get install npm
Ensuite pour installer la bibliothèque Picture-tube, il faut faire :
sudo npm install picture-tube
Si seul l’outil en ligne de commande vous intéresse, ajoutez le paramètre -g
sudo npm install -g picture-tube
Ensuite, pour convertir une image, un petit
picture-tube monimage.jpg
dans le terminal et taaadaaa
Après, pour utiliser la bibliothèque, voici un exemple de code :
var pictureTube = require('picture-tube')
var tube = pictureTube();
tube.pipe(process.stdout);
var fs = require('fs');
fs.createReadStream('robot.png').pipe(tube);Pour tout le reste, c’est par ici.

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.
