Databases, Systems & Networks

When a group of employees collaborate on a project, there is need for handling all aspects and complexities of the project from start to finish, such as task assignment, scheduling, budget management, communication, documentation, and so on. Thus a good project management tool is a necessity for any kinds of businesses or organizations which are involved in a lot of collaborative projects.

Especially web-based online project management tools are the top choice for such environments as different project members can access and share the online tools wherever they are. If your organization requires good web-based project management software, you will find ONLYOFFICE a viable candidate.

ONLYOFFICE is a free and open source office suite that enables seamless project collaboration in the web-based environment. It offers different management tools for documents, emails, events, tasks and client relations. Using ONLYOFFICE, a project manager can schedule the workflow, lead discussions, monitor and coordinate the project progress using Gantt Chart and reports.

In this tutorial, I will describe the main project management features offered by ONLYOFFICE and give some tips to use them more efficiently.

Installing ONLYOFFICE using Docker on Linux

The easiest way to install ONLYOFFICE is by using Docker. The tutorial presented here covers the Docker-based installation instructions for the whole ONLYOFFICE system with online editors integrated for real-time document collaboration.

If you want to install ONLYOFFICE without editors (called « community server »), simply execute the following command:

The above command will download the official ONLYOFFICE Docker image with all dependencies needed for its correct work. For more installation and configuration tips, please refer to the ONLYOFFICE official documentation.

Running a Self-Hosted Web Office

To open your web office, enter in the address bar of your browser localhost (http://IP-Address/) on which the docker is running. The Welcome page will open:

Enter a password and specify the email address you will use to access your office the next time.

Getting Started with a New Project

First, click the Projects link to open the project management tool. To start a new project, click on the Create New…button in the upper left corner and select the Project option from the drop-down list. Fill out the form: specify your project Title and enter a short Description. If necessary, assign a Project Manager and create a project Team.

To restrict access to the newly created project, check the Save this project as private box. Review the project settings and click on the Save button.

Note: to create a new portal, the full privilege administrator or projects management administrator rights are required.

Setting up Your Project Hierarchy

Once the project is started, the next step is to create the project hierarchy which involves the following:

• Set up project key points with milestones
• Distribute the whole amount of work among the team members using tasks
• Link tasks to determine the order in which they need to be performed
• Divide a task into subtasks if it requires several persons to perform several steps

Organize Project Documentation

Keep all the documentation related to your project in one place to access it anytime anywhere. Switch to theDocuments tab on your project page to:

• Upload documents from your hard disk drive
• Download an existing document to your hard disk drive
• Filter and sort documents to facilitate the search
• Copy or move documents to another folder
• Create a new document, spreadsheet or presentation, open and edit the existing ones if the online editorsare installed
• Attach documents to the related tasks

Managing Access Rights

Being a project manager you can manage the project team, tasks, milestones, discussions, comments inside your project; change project status, edit its settings, and also set access rights to project team members for a private project.

By default, each member of your project team can add tasks, assign them to himself or other team members and manage them; start new discussions; add and remove documents; view all content inside your project: milestones, tasks, documents, discussions and contacts.

To restrict the access to an item, switch to the Team tab on your project page, select the team member you wish to set access rights for, and click on one of the links to the right: Discussions, Documents, All Tasks, Milestones,Contacts.

Note: you can set the access rights for each team member unless he/she does not have full privilege administrator or projects management administrator rights.

Monitoring Project using Gantt Chart

Making changes to your project once it is underway is both indispensable and inevitable part of its life cycle. The simplest way to do it with ONLYOFFICE, especially when you manage multiple related projects, is to use Gantt Chart, a bar chart used to illustrate a project schedule.

To open Gantt Chart, click on the Gantt Chart link on the left side panel, or click on the Gantt Chart button in the upper right corner of your project page.

Gantt Chart gives you a panoramic view of all your project activities and allows you to:

• Select one or several projects you wish to coordinate
• View and change the project activity status: open/closed, active/overdue
• Manage the project milestones and tasks: create, edit, close, reopen, delete, etc.
• Link the tasks within your project to show the task dependencies

Useful Tips

1. Leading discussions

To find a solution of problems occurred, you can start a project-related discussion and discuss the issue with your project team within the Discussion tab.

2. Using templates

To easily start a new project, you can use the previously created templates (click on the Create New… button and select the Project Template option to create one).

3. Reporting

To keep up with what each team member is doing, make use of the Reports system. Click on the corresponding link on the left-side panel and generate a report or set up needed parameters once and regularly receive automatic reports by email on certain date and time.

When disaster strikes (and it will), you can put the pieces back together if you’ve got a solid backup solution in place.

function minWord($content)
{
	global $post;
	$content = $post->post_content;
	if (str_word_count($content) < 100 ) //set this to the minimum number of words
	wp_die( __('Error: your post is below the minimum word count. It needs to be longer than 100 words.') );
}
add_action('publish_post', 'minWord');

In the post “What is Network Virtualization?” I described a model where the application’s complete L2-L7 virtual network is decoupled from hardware and moved into a software abstraction layer for the express purpose of automation and business agility. In this post I’ll focus on network security, and describe an imminent firewall form factor enabled by Network Virtualization — the Distributed Firewall.

When you are tasked with monitoring network traffic on the local network, you can consider many different options to do it, depending on the scale/traffic of the local network, monitoring platforms/interface, types of backend database, etc.

ntopng is an open-source (GPLv3) network traffic analyzer which provides a web interface for real-time network traffic monitoring. It runs on multiple platforms including Linux and MacOS X. ntopng comes with a simple RMON-like agent with built-in web server capability, and uses Redis-backed key-value server to store time series statistics. You can install ntopng network traffic analyzer on any designated monitoring server connected to your network, and use a web browser to access real-time traffic reports available on the server.

In this tutorial, I will describe how to set up a web-based network traffic monitoring system on Linux by using ntopng.

Features of ntopng

• Flow-level, protocol-level real-time analysis of local network traffic.
• Domain, AS (Autonomous System), VLAN level statistics.
• Geolocation of IP addresses.
• Deep packet inspection (DPI) based service discovery (e.g., Google, Facebook).
• Historical traffic analysis (e.g., hourly, daily, weekly, monthly, yearly).
• Support for sFlow, NetFlow (v5/v9) and IPFIX through nProbe.
• Network traffic matrix (who’s talking to who?).
• IPv6 support.

Install ntopng on Linux

The official website offers binary packages for Ubuntu and CentOS. So if you use either platform, you can install these packages.

If you want to build the latest ntopng from its source, follow the instructions below. (Update: these instructions are valid for ntopng 1.0. For ntopng 1.1 and higher, see the updated instructions).

To build ntopng on Debian, Ubuntu or Linux Mint:

$ sudo apt-get install libpcap-dev libglib2.0-dev libgeoip-dev redis-server wget libxml2-dev
$ tar xzf ntopng-1.0.tar.gz -C ~
$ cd ~/ntopng-1.0/
$ ./configure
$ make geoip
$ make

In the above steps, « make geoip » will automatically download a free version of GeoIP databases with wget from maxmind.com. So make sure that your system is connected to the network.

To build ntopng on Fedora:

$ sudo yum install libpcap-devel glib2-devel GeoIP-devel libxml2-devel libxml2-devel redis wget
$ tar xzf ntopng-1.0.tar.gz -C ~
$ cd ~/ntopng-1.0/
$ ./configure
$ make geoip
$ make

To install ntopng on CentOS or RHEL, first set up EPEL repository, and then follow the same instructions as in Fedora above.

Configure ntopng on Linux

After building ntopng, create a configuration directory for ntopng, and prepare default configuration files as follows. I assume that « 192.168.1.0/24 » is the CIDR address prefix of your local network.

$ sudo mkir /etc/ntopng -p
$ sudo -e /etc/ntopng/ntopng.start

--local-networks "192.168.1.0/24"
--interface 1

$ sudo -e /etc/ntopng/ntopng.conf

-G=/var/run/ntopng.pid
