Installing and configuring Postfix Ubuntu 10.04

Posted on by admin

Introduction

Postfix is the default Mail Transfer Agent (MTA) for Ubuntu. It is in Ubuntu’s main repository, which means that it receives security updates. This guide explains how to install and configure postfix and set it up as an SMTP server using a secure connection.

 

What is a Mail Transfer Agent

In other words, it’s a mail server not a mail client like Thunderbird, Evolution, Outlook, Eudora, or a web-based email service like Yahoo, GMail, Hotmail, Earthlink, Comcast, SBCGlobal.net, ATT.net etc…. If you worked for a company named Acme and owned acme.com, you could provide your employees with email addresses @acme.com. Employees could send and receive email through your computer, but not without your computer running all the time. If all your email addresses are at a domain (@gmail.com, @yahoo.com) you do not own (you don’t own Google) or do not host (acme.com) then you do not need this at all.

Enable SSI on Apache2 under Ubuntu

Posted on by admin

Tested on:
– Ubuntu Linux 10.10 Maverick Meerkat (2010-11-21)
– Ubuntu Linux 7.10 Gutsy Gibbon
– Ubuntu Linux 6.06 Dapper Drake
– Ubuntu Linux 5.10 Breezy Badger

 

1)  Optional: Install the Apache2 httpd server if not already installed.

sudo apt-get install apache2

2) Create the following symlink.
sudo ln -s /etc/apache2/mods-available/include.load /etc/apache2/mods-enabled

3) Open the /sites-available/default file and add the text with the yellow background.
sudo gedit /etc/apache2/sites-available/default

...
<Directory /var/www/>
Options Indexes FollowSymLinks MultiViews +Includes
AllowOverride None
Order allow,deny
allow from all
AddType text/html .shtml
AddOutputFilter INCLUDES .shtml
</Directory>
...

4) Restart Apache2 and create a SSI test file (ssi-test.shtml) and save it in the directory /var/www/.

sudo apache2ctl restart

sudo vim /var/www/ssi.shtml

<html>
<head>
<title>SSI Page</title>

</head>
<body>
<!--#echo var="DATE_LOCAL" -->
</body>
</html>

5) Test SSI in your web browser.
http://localhost/ssi.shtml

If your browser displays the local date (eg Monday, 29-Jul-2013 14:32:58 BST), SSI would be working.

Yeah !!

Recording a session for a user when he / she logs in ssh

Posted on by admin

 

To start recording each session add this to the users .profile file

DATE=$(date +”%Y%m%d%H%M”)
mkdir /log/$DATE
script -t 2>/log/$DATE/bashlogs.timing -aqf /log/$DATE/bashlogs.script

 

to playback go to

/log/<timestamp>

and run

scriptreplay  bashlogs.timing bashlogs.script 3

where the 3 is the speed up factor.
