Configuring mutt to work with GMAIL

Mutt is a mail client , that you can configure easier in Linux , i will start with explaining the installation and the configuration of the tool , and some example to send a simple email :

• sudo apt-get update         #It's always a good idea to update your sources list before you start with installing any thing new .
• sudo apt-get install mutt         #This command will install the client for you .
• cd         #This will take you to your home dir , and there you will find a dir called .mutt
• cd .mutt
• vi muttrc         # Edit the file like the below example :

Ex :

hdr_order Date From To Cc

ignore "Authentication-Results:"

ignore "DKIM-Signature:"

ignore "DomainKey-Signature:"

set certificate_file="~/.mutt/certificates"

set editor='nano'

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

set from="YourEmail@gmail.com"

set header_cache="~/.mutt/cache/headers"

set imap_check_subscribed

set imap_keepalive=300

set imap_pass="YourPassword"

set imap_user="set imap_user="YourEmail@gmail.com"

set markers=no

set message_cachedir="~/.mutt/cache/bodies"

set move=no

set postponed="imaps://imap.gmail.com/[Gmail]/Drafts"

set realname="YourName"

set smtp_pass="YourPassword"

set smtp_url="smtp://YourEmail@smtp.gmail.com:587/"

set sort_aux='last-date-received'

set sort='reverse-threads'

set spoolfile=imaps://imap.gmail.com:993/INBOX

unset imap_passive

You have new mail in /var/mail/root

* Please replace YourName , YourEmail , YourPassword .

And this is an example for sending email with mutt :

Ex :

      echo -e "Hloo \nThis is my body email" | mutt -s "This is my subject" ToEmail@koko.com

How to connect WiFi from Linux command line : WPA/WPA2-PSK

First of all we will have to check that we are working with the wpa configuration file ,

Be sure that you have this section in /etc/network/interfaces :

•    sudo su 
•    vi /etc/network/interfaces
•    And add the following section : , you can figure out what is your interface name with the             command ifconfig , usually it's wlan0 or 1 ..

          auto wlan0
          iface wlan0 inet dhcp
          wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

•   To generate the network block use the command : wpa_passphrase essid_name supersecretpassword

   
     and this will create something like the bellow , and then all you have to do is to add this block to
     /etc/wpa_supplicant/wpa_supplicant.conf

•    So vi /etc/wpa_supplicant/wpa_supplicant.conf , and add this :

     network={ 
          ssid="MyAP111" 
          #psk="MyPassword" 
          psk=cc2499f98beb4dc374d206e56786686cfea3bbb741ac173dbd2a2514e461230a
