Art By Annette at Lorenz Gallery

Annette was born on March 26th 1949 and sadly passed away at the age of 64 during the summer of 2013. She always loved art, and found it to be a wonderful way of expressing her feelings. Drawing was the easiest way to do this.

She came from a family of 3, and was a truly loving daughter, supporting and caring for her mother until the end. She had a very close relationship with all of her family and was greatly loved by her nieces and nephews. In return Annette offered her time generously without thought for herself.

She lived her whole life in London, preferring city life to that of any other. London afforded Annette the luxury of access to the most modern and exciting trends.

Delete All base on filename extension in folder and subfolders

Using Terminal and Find command.

This command starts in the current directory, recursing through the entire subtree, looking for files only that end with ‘.jpg’. It will delete any such files.

Also adding an -delete it should do the same.

How to send mails in POSTFIX through external SMTP

Postfix Mail

Postfix Mail

This short guide shows how you can set up Postfix to relay emails through another mailserver. This can be useful if you run a Postfix mailserver in your local network and have a dynamic IP address because most dynamic IP addresses are blacklisted today. By relaying your emails through another mailserver that is hosted on a static IP address in a data center (e.g. your ISP’s mailserver) you can prevent your emails from being categorized as spam.

First step, you will need to make changes in your configuration file (in standard postfix configuration it would be /etc/postfix/main.cf). You need to add at the end of configuration file following lines:

Backup & Restoring Tips for Large Files in Plesk 11.0.9

When it comes to Plesk Backup Manger there are few things that you might need to configure in order to backup large files successfully.

UFW – Uncomplicated Firewall

The default firewall configuration tool for Ubuntu is ufw. Developed to ease iptables firewall configuration, ufw provides a user friendly way to create an IPv4 or IPv6 host-based firewall. By default UFW is disabled.

Gufw is a GUI that is available as a frontend.

Basic Syntax and Examples

Default rules are fine for the average home user

When you turn UFW on, it uses a default set of rules (profile) that should be fine for the average home user. That’s at least the goal of the Ubuntu developers. In short, all ‘incoming’ is being denied, with some exceptions to make things easier for home users.

Enable and Disable

Enable UFW

To turn UFW on with the default set of rules:
