Conclusion

These are the less popular, yet important Linux administration tools. They can help user in their day to day activities. In our upcoming articles, we will try to bring some more Admin/user tools.

Have fun!

The post 10 Useful Utilities For Linux Users appeared first on Unixmen.

We have tested many versions of Fedora Linux. Yet they have always remained in desktop format. I have been involved with Fedora usage dating right back to the days of Fedora Core 5.

For the release of Fedora 23, we are taking a look at both the Desktop and Server versions. The latter of which admittedly, we will be giving more focus in this Review.

Cockpit

The Fedora 23 package comes with the state-of-the-art Cockpit. It is a web-based management console which is accessed through a web browser and aims to make the server status and monitoring tasks much simpler.

Fedora Server aims to provide a solid, server focused operating system within the Fedora line-up and also competes with Ubuntu Server. Whilst the latter remains a console-based operating system, Fedora combined with Cockpit does feel like it has filled the void and taken it one step further by including a web-based server management tool by default.

Web server

Once Fedora 23 Server is installed, the Cockpit console can be accessed from a web browser. Once accessed, you can login to the server via the Regular User (with or without administrative privileges) or the Server Administrator account. This will really depend how it has been configured upon installation.

Once you log in to Cockpit, you will be presented with the following interface. This presents a Summary of the system specifications and the Fedora software system details.

You can click on Services to view all running System Services and also change using the displayed buttons, which can modify which Services you see displayed.

The Storage component of Cockpit can be very useful. We only have a simple setup running and configured inside Oracle VM VirtualBox. But when running in full server mode with multiple or many drives operational, the Storage component and management tool is critical.

The Networking component is pretty self explanatory. It’s your usual network monitoring tool which displays relevant networking details.

Again, we are running a very simple setup, so our own example details are bare at best. But it’s enough to display Sending/Receive packet data, list the network device and any relevant Logs.

The Administrator Accounts component simply lists the users who are registered to login to the server. On our server, we have an account for myself and the Root account. My personal account is set for limited role, therefore any proper administrative tasks must be carried out by the Root account to allow for full system access. As we stated earlier in the Review, this will depend on how the server is configured in the early stage of Anaconda.

The Terminal component is probably going to be a place of comfort for seasoned Administrators who like to have absolute access to the very core of their system. Usually, this means by having access to a Terminal shell. Cockpit has this covered of course, all accessible from within the Cockpit console and through the web browser interface.

But note, what actions you perform from the Terminal essentially depends on what access the account has that you have logged into Cockpit with. Unless you gain root privileges, of course. We really shouldn’t have to delve into this in great detail, as its behavior is exactly the same as what it is running directly on desktop Linux, only this time its running within the web browser interface of the Cockpit console.

For system monitoring information and data, you can simply enter the Dashboard tab.

Here you will find a set of system monitoring tabs – CPU, Memory (RAM), Network and Disk I/O. This can be useful to have them all in separate tabs, away from the distractions of all the other Cockpit components if you want to specifically focus your monitoring task on one specific area.

CPU monitor:

Memory (RAM) monitor:

Network monitor:

Disk I/O monitor:

For simple server testing, we attempted to install Apache and did experience some trouble with getting the service to start properly. After several failed attempts, we did decide to drop Apache and give Lighttpd a shot. It worked on first attempt and we were able to get the server directly delivering web files in just minutes.

When you have finished your tasks within Cockpit, the user can easily log out of the interface much like the Desktop version, by using the Username options in the top-right corner.

Anaconda – Graphical installer for Server

The installer uses the same Anaconda package as the Desktop version of Fedora. This is excellent. Despite our initial gripes we’ve raised in the past about the new Anaconda package, we reckon it has matured very much and is ready to redeem itself as one of the best Linux installers available.

It is interesting tho note that Fedora has chosen to build the Server installation around the Anaconda package and use a graphical installer for a server-based Linux operating system. But like we pointed out earlier, it’s as though the Fedora Developers have looked at Ubuntu Server and taken a more user-friendly approach and direction for a server-based operating system. This is a good thing and the extra attention given, does show.

Desktop

To complement this Review, we decided to additionally run the Desktop version of Fedora 23. This was also installed inside Oracle VM VirtualBox.

Fedora 22 was an excellent release. We were so impressed we would declare it our favorite release of Linux to date. Although we missed out on the deadline to publish a review of Fedora 22, we have loved every minute of it and it’s an awesome display of modern Linux, running the very best of everything. It was also one of the first Linux distributions to come through our Labs running the Linux 4.x kernel branch.

It’s a big claim, yes, we know. What does that mean for our thoughts on Fedora 23? Well it’s safe to say that not much has changed. This is nothing bad though as that’s just how good we believe Fedora 22 was. Fedora 23 has built upon that strength and robust reliability and delivered a new release which continues the trend of its predecessor.

Fedora 23 runs excellent. Our Desktop version was installed running a slightly older version of the Linux kernel than what we have installed on the Server version. But this is easily fixed by running a system-wide update using DNF. This will install the latest available kernel for Fedora 23, in addition to all other software packages on the system.

Our Desktop version contained the XFCE desktop-environment, which is nice to see has been updated to the latest package – 4.12.

There’s not much else different other than the usual available packages shipped with Fedora and XFCE, albeit updated versions.

Conclusion

Fedora 23 Server can be whatever you want it to be. We put it to work as a simple web server. You can really go full steam ahead and install an entire LAMP stack, but we opted for a limited Lighttpd configuration instead. You could simply leave it on your network as a file server with out-of-the-box SSH access configured. Or you could get more tricky and put it into a full server role which would require a lot more in-depth configuration and detail than what we can cover in this Review. That’s before we have even brushed on its potential for Cloud options. It’s worth noting that this is all deployed and supported completely free of any contract fees associated with Fedora, unlike its big commercial partner, Red Hat.

Fedora 23 is great for small business who are looking at options for cutting down on IT costs related to software. If Fedora doesn’t suit the task at hand, we remind our readers not to forget about CentOS 7.0. Sure, Ubuntu is also an equal potential option with solid and reliable performance. But it’s difficult to look past Fedora’s fine polish and overall friendly take on a server operating system. Additionally, the simple fact that Cockpit is so well equipped and installed by default with the core system, makes Fedora 23 that little bit more tempting.

Arch Linux is a simple, fast, powerfull distrobution and it always provides the last version of kernel and softwares so if you wanna have the latest version of PHP, Apache, MySQL and etc it’s really good and recommanded for web developing.

In this tutorial we ganna install Lamp on Arch Linux with the latest version of PHP (PHP7) from AUR, but you should know that installing Lamp with PHP7 may makes some problems because it’s in unofficial repositories, so you should take the risk by yourself !

1- Installation and runing services

First install PHP7 and it’s needs from AUR by the following command :

yaourt -S php7 php7-apache php7-mcrypt

Now install Apache and Mysql (mariaDB) :

sudo pacman -S apache mysql php-apache mariadb

Enable and start Apache service by this command :

sudeo systemctl enable httpd

sudo systemctl start httpd

See the status and make sure it’s okay :

systemctl status httpd

The last line output should be like this :

Started Apache Web Server

Start and enable MySQL now by this commands :

sudo systemctl enable mysqld

sudo systemctl start mysqld

Check the status :

systemctl status mysqld

If you get the following sentence in output your service is okay :

Started MariaDB database server.

If your status shows MySQL is not okay use following command and try again :

sudo mysql_install_db --user=mysql --basedir=/usr --datadir=/var/lib/mysql

2-MySQL Configuration

You should secure MySQL so use this command to start :

sudo mysql_secure_installation

Look at the following picture :

After the sentence ” Enter current password for root (enter for none): ” give your root password the then it will asks you few questions answer them all with yes.if you wanna use Jommla or WordPress as localhost on your Arch Linux you need to know how to create or remove database in MySQL but first you should enter to MySQL by this command :

mysql -u root -p

After you enterd, make a user in MySQL by following commands :

CREATE USER 'hossein'@'localhost' IDENTIFIED BY 'your_pass';
GRANT ALL PRIVILEGES ON mydb.* TO 'hossein'@'localhost';
FLUSH PRIVILEGES;
quit;

Don’t forget to put your own information in creating user commands. After you creat a user you can manage your databases for example for creating a database you can use this command :

CREATE DATABASE;

If you want to see your databes use following command :

SHOW DATABASES;

Or for removing a database you can “DROP” like this :

DROP DATABASE database_name;

For getting out of MySQL use this command :

quit;

For more information about MySQL command see here.

3- Apache Configuration

Here we config Apache so enter following command :

sudo nano /etc/httpd/conf/httpd.conf

Now that text file is open add the following lines to bottom of it :

<IfModule dir_module>
	<IfModule php7_module>
		DirectoryIndex index.php index.html
		<FilesMatch "\.php$">
			SetHandler application/x-httpd-php
		</FilesMatch>
		<FilesMatch "\.phps$">
			SetHandler application/x-httpd-php-source
		</FilesMatch>
	</IfModule>
</IfModule

Restart Apache service :

sudo systemctl restart httpd

Apache is successfully configured now :))

4-PHP

For getting your php information first you should make a text file so do like following command :

sudo nano /srv/http/info.php

Add this lines to the file :

<?php
phpinfo();
?>

Save the file with ctrl + o and close it with ctrl +x then enter this command :

cd /srv/http

Let info.php to have excute permission :

sudo chmod u+x info.php

Run the file :

php info.php

If php7 were okay first of the output should be like this with other informations :

[hossein@hossein http]$ php info.php
phpinfo()
PHP Version => 7.0.0

If it is, Lamp is ready !!
( Thanks to my friend Saeed for contribute )
Enjoy

Create LVM

First Create physical volume, then Volume group followed by Logical volume:

root@user:/home/user# pvcreate /dev/sdb1
 Physical volume "/dev/sdb1" successfully created
root@user:/home/user# vgcreate um_vg /dev/sdb1
 Volume group "um_vg" successfully created
root@user:/home/user# lvcreate -L +1G -n xfs_lv um_vg   
 Logical volume "xfs_lv" created.

Now, create XFS file system, before that install xfs file system utilities in Ubuntu

# apt-get install xfsprogs

Create a directory where this xfs file system will be mounted

# mkdir /home/user/xfs

Create .xfs file system

# mkfs.xfs /dev/um_vg/xfs_lv

Sample output

Again have a look on mounted file system whether it got extended or not

#df -h /dev/um_vg/xfs_lv

Sample output

Filesystem                Size  Used Avail Use% Mounted on
/dev/mapper/um_vg-xfs_lv  1.1G   33M 1006M   4% /home/user/xfs

Now, compare with previous file size, you will notice that file system size got increased automatically as we are using XFS file system.

Have a nice day!!

Introduction

Advanced Policy Firewall or APF is iptable based firewall system which is a free distribution, this firewall is designed to meet today’s security based essential needs.The firewall is designed to be very informative and present the user with an easy to use follow process.

Features Highlight

The filters perfromed by APF can be catagourised in three parts

static rule based policy.

It define how firewall should handle certain traffic in specific conditions while giving access to certain port or adding some ip address as trusted one.

Connection based stateful policy

Firewall will identify valid/legitimated packets from the different types of connections and will allow only valid connections which are allowed in firewall rules and other will be rejected.

Sanity based policy

Can identify network attacks by screening or scrutinizing packets, it will discard and log any data which is considered as inappropriate.

Installation

It is recommended to have at least 2 LAN cards, 4 GB RAM, dual core processor and 1 GB free disk space to dedicate  your system as APF firewall.

Update Ubuntu 15.10

# apt-get update

Download package

# wget http://www.rfxn.com/downloads/apf-current.tar.gz

Extract package

# tar -xvf apf-current.tar.gz

Extract and install package

# cd apf-9.7-2/
# ./install.sh

Sample output

Installing APF 9.7-2: Completed.

Installation Details:
  Install path:         /etc/apf/
  Config path:          /etc/apf/conf.apf
  Executable path:      /usr/local/sbin/apf

Other Details:
  Listening TCP ports: 53,631
  Listening UDP ports: 53,68,631,5353,23566,47956
  Note: These ports are not auto-configured; they are simply presented for information purposes. You must manually configure all port options.

Now have a look in /etc/apf/conf.apf

# The installation path of APF; this can be changed but it is not recommended.
INSTALL_PATH="/etc/apf"

# Untrusted Network interface(s); all traffic on defined interface will be
# subject to all firewall rules. This should be your internet exposed
# interfaces. Only one interface is accepted for each value.
IFACE_IN="eth0"
IFACE_OUT="eth0"

# Trusted Network interface(s); all traffic on defined interface(s) will by-pass
# ALL firewall rules, format is white space or comma separated list.
IFACE_TRUSTED="eth0"

# This option will allow for all status events to be displayed in real time on
# the console as you use the firewall. Typically, APF used to operate silent
# with all logging piped to $LOG_APF. The use of this option will not disable
# the standard log file displayed by apf --status but rather compliment it.
SET_VERBOSE="1"

Let us explain some of the important parameters which are important in this configuration file

IFACE_IN=”eth0″
IFACE_OUT=”eth0″

Interface in and interface out define which interface you will be using for firewall as inbound and outbound

DEVEL_MODE=”1″

Keep Developer mode as 1

IG_TCP_CPORTS

Define allowed TCP ports

IG_UDP_CPORTS

Define allowed UDP ports

Command Examples

To start firewall

# apf -s

To stop firewall

# apf -f

Output

apf(7480): {glob} flushing & zeroing chain policies
apf(7480): {glob} firewall offline

To restart firewall

# apf -r

To dump current status of firewall on terminal

# apf -st

To deny some host

# apf -a 192.168.1.1

It will add IP ADDR to trusted address  and entries goes to  /etc/apf/allow_hosts.rules

# apf -d 192.168.1.1

Above command will add IP ADDR to deny, entries goes to  /etc/apf/deny_hosts.rules

# apf -u 192.168.1.1

Remove entries either from trsuted or from deny hosts rules

Now your firewall is ready to work in an easy to use and deploy manner.

Have fun

Preface

Most of the IT or non-IT organization/companies generally possess hybrid environment .i.e. they have Linux based as well as Microsoft based desktops or servers.It becomes a challenge of IT/System administrators to ensure availability of all of the resources such as printer sharing, directory sharing, Internet sharing etc, especially when some organization is looking for some low cost solutions for such resource management. Although a lots of firewalls are available in open source but very rare dedicated OS are available which can act as complete All-in-One IT infrastructure management solution provider. Zentyal is one of such available application server, a article based on zentyal was published few months before refer following link to know more about zentyal http://www.unixmen.com/how-to-setup-zentyal-server-4-1/

On December 28, 2015, the free software world lost of one its smartest programmers and software engineers, Ian Murdock. Ian was most well known for his founding and creation of one of the most respected Linux distributions to date, Debian.

Through Ian’s creation of Debian, the Linux operating system has gained a reputation for being one of the most solid, reliable and versatile Linux operating systems for the server and desktop sectors.

Debian has provided the basis for many Linux based operating systems, including the world’s most popular Linux system, Ubuntu.

Debian development continues today through the volunteer efforts of thousands of software developers and engineers. Whilst Linus Torvalds is often considered the grandfather of Linux, Debian is equally considered the grandfather of Linux based operating systems.

The tireless work Ian Murdock put into Debian and other projects earned him the respect that he deserved.

In January 2006 Ian’s hard work led him to a role as Chief Technology Officer (CTO) with the Free Standards Group, which eventually evolved into the Linux Foundation. Ian continued his role as CTO until the following year of March 2007 where he was employed at Sun Microsystems to lead Project Indiana. When Sun Microsystems merged with software giant Oracle, Ian resigned from the company.

From 2011-2015 Ian was employed by Salesforce Marketing Cloud, until in November 2015 he joined Docker Inc. His role with Docker was short-lived, when on December 30, 2015, Docker announced his tragic passing.

Whilst specific circumstances surrounding his passing have not been officially released, there are indications that Ian Murdock had taken his own life. Absolutely tragic and deeply saddening for Ian’s family, friends, colleagues and all of the free and open-source software community.

It’s important to remember the legacy that Ian left behind, through his work as a free and open-source software developer and engineer. More specifically, Ian will always be remembered for the founding and creation of the world’s most loved and respected Linux operating systems, Debian. May you rest in peace Ian Murdock, you will be sorely missed.

As a sign of our respect to Ian, today we finish our tribute by publishing the Debian Manifesto written by Ian Murdock in 1994.

A.1 What is Debian Linux?

Debian Linux is a brand-new kind of Linux distribution. Rather than being developed by one isolated individual or group, as other distributions of Linux have been developed in the past, Debian is being developed openly in the spirit of Linux and GNU. The primary purpose of the Debian project is to finally create a distribution that lives up to the Linux name. Debian is being carefully and conscientiously put together and will be maintained and supported with similar care.

It is also an attempt to create a non-commercial distribution that will be able to effectively compete in the commercial market. It will eventually be distributed by The Free Software Foundation on CD-ROM, and The Debian Linux Association will offer the distribution on floppy disk and tape along with printed manuals, technical support and other end-user essentials. All of the above will be available at little more than cost, and the excess will be put toward further development of free software for all users. Such distribution is essential to the success of the Linux operating system in the commercial market, and it must be done by organizations in a position to successfully advance and advocate free software without the pressure of profits or returns.

A.2 Why is Debian being constructed?

Distributions are essential to the future of Linux. Essentially, they eliminate the need for the user to locate, download, compile, install and integrate a fairly large number of essential tools to assemble a working Linux system. Instead, the burden of system construction is placed on the distribution creator, whose work can be shared with thousands of other users. Almost all users of Linux will get their first taste of it through a distribution, and most users will continue to use a distribution for the sake of convenience even after they are familiar with the operating system. Thus, distributions play a very important role indeed.

Despite their obvious importance, distributions have attracted little attention from developers. There is a simple reason for this: they are neither easy nor glamorous to construct and require a great deal of ongoing effort from the creator to keep the distribution bug-free and up-to-date. It is one thing to put together a system from scratch; it is quite another to ensure that the system is easy for others to install, is installable and usable under a wide variety of hardware configurations, contains software that others will find useful, and is updated when the components themselves are improved.

Many distributions have started out as fairly good systems, but as time passes attention to maintaining the distribution becomes a secondary concern. A case-in-point is the Softlanding Linux System (better known as SLS). It is quite possibly the most bug-ridden and badly maintained Linux distribution available; unfortunately, it is also quite possibly the most popular. It is, without question, the distribution that attracts the most attention from the many commercial "distributors" of Linux that have surfaced to capitalize on the growing popularity of the operating system.

This is a bad combination indeed, as most people who obtain Linux from these "distributors" receive a bug-ridden and badly maintained Linux distribution. As if this wasn't bad enough, these "distributors" have a disturbing tendency to misleadingly advertise non-functional or extremely unstable "features" of their product. Combine this with the fact that the buyers will, of course, expect the product to live up to its advertisement and the fact that many may believe it to be a commercial operating system (there is also a tendency not to mention that Linux is free nor that it is distributed under the GNU General Public License). To top it all off, these "distributors" are actually making enough money from their effort to justify buying larger advertisements in more magazines; it is the classic example of unacceptable behavior being rewarded by those who simply do not know any better. Clearly something needs to be done to remedy the situation.

A.3 How will Debian attempt to put an end to these problems?

The Debian design process is open to ensure that the system is of the highest quality and that it reflects the needs of the user community. By involving others with a wide range of abilities and backgrounds, Debian is able to be developed in a modular fashion. Its components are of high quality because those with expertise in a certain area are given the opportunity to construct or maintain the individual components of Debian involving that area. Involving others also ensures that valuable suggestions for improvement can be incorporated into the distribution during its development; thus, a distribution is created based on the needs and wants of the users rather than the needs and wants of the constructor. It is very difficult for one individual or small group to anticipate these needs and wants in advance without direct input from others.

Debian Linux will also be distributed on physical media by the Free Software Foundation and the Debian Linux Association. This provides Debian to users without access to the Internet or FTP and additionally makes products and services such as printed manuals and technical support available to all users of the system. In this way, Debian may be used by many more individuals and organizations than is otherwise possible, the focus will be on providing a first-class product and not on profits or returns, and the margin from the products and services provided may be used to improve the software itself for all users whether they paid to obtain it or not.

The Free Software Foundation plays an extremely important role in the future of Debian. By the simple fact that they will be distributing it, a message is sent to the world that Linux is not a commercial product and that it never should be, but that this does not mean that Linux will never be able to compete commercially. For those of you who disagree, I challenge you to rationalize the success of GNU Emacs and GCC, which are not commercial software but which have had quite an impact on the commercial market regardless of that fact.

The time has come to concentrate on the future of Linux rather than on the destructive goal of enriching oneself at the expense of the entire Linux community and its future. The development and distribution of Debian may not be the answer to the problems that I have outlined in the Manifesto, but I hope that it will at least attract enough attention to these problems to allow them to be solved.
