Ubuntu Unity Nonsense

Just upgraded the ubuntu to 11.04 (Natty Narwhal) and what a surprise! I got MacOS look and feel.

Doing some research and I can’t believe Gnome3 has the same STUPID look as MacOS OMG!!!

What innovation  you see at copying the same OS from MAC. I remember the days when the Linux desktop looks innovating and it was pleasure to work with so many options. Now everything is going the Apple way.

I felt depressed is there around at least one windows manager which is not influenced from Apple?

I hate Dock launchers –  looks not innovating – it looks clumsy and old. Everything which is copied clumsy!

Gnome3 – you are going on the same path as Unity!

Windows7 – is 100 times better because it has its OWN LOOK AND FEEL – I’d rather work with windows7 than on a Gnome3/Unity. Blah!

The solution?

Xfce desktop is now closes to what Gnome was

Relaying Postfix SMTP via smtp.gmail.com

This article is from ubuntu-tutorials.com

I’ve got a few servers in different places around the country and try to monitor them using the logwatch utility.  One problem that I’ve run into however is that a few of these servers are not able to send their logwatch emails to me, based on email restrictions by the ISPs.  I spent some time this afternoon researching what was required to have my servers authenticate to my gmail account and send me the mail that way.  This setup assumes Ubuntu 8.04 (or later) and Postfix.

Install the required packages

sudo aptitude install postfix libsasl2 ca-certificate libsasl2-modules

Configure Postfix

This tutorial will not outline how to configure your postfix server, but we’ll jump directly to the relayhost section.  You’ll want to add the following lines to your /etc/postfix/main.cf file:

relayhost = [smtp.gmail.com]:587
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_sasl_security_options = noanonymous
smtp_tls_CAfile = /etc/postfix/cacert.pem
smtp_use_tls = yes

The above lines are telling Postfix that you want to relay mail through gmail on a specific port, telling it to authenticate, and where to find the username and password.  The last three lines specify the authentication types supported, where the certificate authority file is and that it should use tls.

Define Username and Password

Next we’ll need to populate the sasl_passwd file.  Create the file /etc/postfix/sasl_passwd with the following contents:

[smtp.gmail.com]:587    user.name@gmail.com:password

This file should have restrictive permissions and then needs to be translated into a .db that Postfix will read.

sudo chmod 400 /etc/postfix/sasl_passwd
sudo postmap /etc/postfix/sasl_passwd

At this point you can restart Postfix and it should work, however it will complain about not being able to authenticate the certificate.  To take care of this issue we’ll use the ca-certificate package we installed and tell it where it can validate the certificate.

cat /etc/ssl/certs/Thawte_Premium_Server_CA.pem | sudo tee -a /etc/postfix/cacert.pem

Go ahead and reload postfix (sudo /etc/init.d/postfix reload) and you should be set.

X Windows for MS Windows

The one I use is Xming but it is rare. Most often I prefer the integrated in Gnome VNC.

The reason I am posting this link is that sometimes I really need and want to connect to my desktop machine in this way but I cant find good software. So I decide that my blog is the perfect place to note this.
