Installing and Configuring Postfix

Postfix — mail transfer agent (MTA) with open source.

Assume that the IP address of the server is configured with a domain name, from which the mail will be sent in the future.

I installed and configured Samba once on the next Ubuntu Server 14.04.5 LTS as described in this article Installing and Configuring Samba in Linux.

And after restarting the system, not everything was started, smbd and nmbd were started, if they can be restarted like this:

sudo restart smbd
sudo restart nmbd

But you can not connect to the disk and you still had to execute the command:

sudo service samba start

For samba to automatically start at system startup, execute the following command:

sudo update-rc.d samba defaults

Done.

Conky – system monitor.

The installation command in Ubuntu:

sudo apt-get install conky

In CentOS/Fedora:

sudo yum install conky

Start command:

conky

At the first start, I displayed this window:

The configuration files are located in the /etc/conky/.

To read the built-in documentation, you can run the following command:

man conky

Example of launching in a background with an update interval of 2 sec.:

conky -d -u 2

To stop, you can use the command:

pkill conky

Ostinato – program for network analysis and traffic generation.

The Ostinato installation command in Ubuntu:

sudo apt-get install ostinato

The launch is performed in a graphical mode by reference or by the command:

sudo ostinato

To remove Ostinato, you can run the following command:

sudo apt-get purge ostinato

Eclipse – the environment for developing modular cross-platform applications.

Cron — task scheduler in UNIX-like operating systems, used for periodic execution of tasks at a certain time.

dhcpdump – sniffer utility for analyzing DHCP packets.

To open the TFTP port in IPTables, we will run the rule:

On the test I will create a SWAP partition in Ubuntu Server.
So, we think what size of the paging file we need and create an empty file:
