Command-line email client mutt has a well-deserved reputation as a powerhouse of an email client. It’s fast, flexible and, best of all, surprisingly easy to use.  In this guide we give you Step-By-Step instructions for setting up Mutt email client on Ubuntu using Gmail.

1. sudo apt-get install mutt

2. mkdir -p ~/.mutt/cache/headers mkdir ~/.mutt/cache/bodies touch ~/.mutt/certificates

3. Copy and paste configuration below into a new file, save it in your home directory, and rename it to .muttrc

# A basic .muttrc for use with Gmail

# Change the following six lines to match your Gmail account details

set imap_user = “YOUR.EMAIL@gmail.com”

set imap_pass = “PASSWORD”

set smtp_url = “smtp://YOUR.EMAIL@smtp.gmail.com:587/”

set smtp_pass = “PASSWORD”

set from = “YOUR.EMAIL@gmail.com”

set realname = “YOUR NAME”

# Change the following line to a different editor you prefer.

set editor = “nano”

# Basic config, you can leave this as is

set folder = “imaps://imap.gmail.com:993″

set spoolfile = “+INBOX”

set imap_check_subscribed

set hostname = gmail.com

set mail_check = 120

set timeout = 300

set imap_keepalive = 300

set postponed = “+[GMail]/Drafts”

set record = “+[GMail]/Sent Mail”

set header_cache=~/.mutt/cache/headers

set message_cachedir=~/.mutt/cache/bodies

set certificate_file=~/.mutt/certificates

set move = no

set include

set sort = ‘threads’

set sort_aux = ‘reverse-last-date-received’

set auto_tag = yes

ignore “Authentication-Results:”

ignore “DomainKey-Signature:”

ignore “DKIM-Signature:”

hdr_order Date From To Cc

alternative_order text/plain text/html *

auto_view text/html

bind editor <Tab> complete-query

bind editor ^T complete

bind editor <space> noop

# Gmail-style keyboard shortcuts

macro index,pager y “<enter-command>unset trash\n <delete-message>” “Gmail archive message”

macro index,pager d “<enter-command>set trash=\”imaps://imap.googlemail.com/[GMail]/Bin\”\n <delete-message>” “Gmail delete message”

macro index,pager gi “<change-folder>=INBOX<enter>” “Go to inbox”

macro index,pager ga “<change-folder>=[Gmail]/All Mail<enter>” “Go to all mail”

macro index,pager gs “<change-folder>=[Gmail]/Starred<enter>” “Go to starred messages”

macro index,pager gd “<change-folder>=[Gmail]/Drafts<enter>” “Go to drafts”

4. Open up the ~/.muttrc file in your favorite text editor, add your name, Gmail address and password—everything you’ll need to alter is in ALL CAPS—and save the file.

5. Run it from the command line by simply typing mutt. The first time you do this, you’ll be prompted to accept two SSL certificates from Google; press ‘a’ to always accept these certificates. You should now be greeted by your Gmail inbox

Ubuntu has announced an operating system for tablets dubbed ‘Ubuntu for Tablet’ that is says will work on tablets of any size.  The OS will work on both entry level tablets as well as high-end tablets with enterprise specifications, the operating system offers multitasking, safer sharing, instant launch of applications through the menu bar on the left, effortless switching between applications among other features.  Canonical has put out specifications of the tablets that would be required for an entry level consumer Ubuntu tablet experience as well as High-end Ubuntu enterprise tablet experience.

For entry level experience, Ubuntu for tablet requires a minimum of Dual Core Cortex A15 processor and 2GB of RAM. The tablet can be of any screen size from 7 to 10 inches and should have at least 8GB of storage.

For high-end tablet experience users need to go for a tablet that has at least a Quad-core A15 or Intel x86 processor and is loaded with 4GB of RAM. With 8GB minimum flash storage, the recommended screen size is anywhere between 10-12 inch.

The Ubuntu for tablet is loaded with both native as well as web applications. The operating system also supports cloud based applications for both consumer as well as enterprise users.

The Linux-based Ubuntu OS, specifically targeting those of the Nexus variety. The OS will be available for the Nexus 7 and Nexus 10.  Owners of the Nexus 4 and Galaxy Nexus smartphones will receive access to the OS on the same day and the OS will be featured at Mobile World Congress next week.

The FreeBSD project has sought $500,000 in donations by year end to allow it to continue to offer to fund, manage projects and sponsor FreeBSD events, developer summits and provide travel grants to FreeBSD developers. But with the end of this year fast approaching, it has raised just over $280,000, far short of its target.

As most people know Apple is BSD under the hood using Darwin as the core of Apple OS X.  Apple borrows FreeBSD’s virtual file system, network stack, and components of its userspace.  Much of FreeBSD now also forms the basis of Apple OS X and OS X Server.  Apple, the first major computer company to make Open Source development a key part of its software strategy and continues to use and release significant quantities of open source software.

I do think that BSD is struggling with funding cause of Linux popularity boom over last few years. Linux has taken great strides to become more commercial and get more support on server backed end with Dell, HP and IBM. I do not see BSD having big leaps like that plus they need a better PR rep. Every customer I go to ask for Linux because we are a Linux shop on our commercial side I very rarely see anyone ask for BSD support or do I see many BSD servers in use.

If you want to start the desktop from CLI console (not SSH session), use following command:

$ startx

First do a standard install of CentOS 6.  After the standard install IP all the network cards to the proper IP addresses before you install Packetfence.  After that follow these steps-by-step instructions to install packetfence.
