The program also allows you to restart or shut down a remote computer, as well as install on it required programs or delete unnecessary ones.
This article will, to some extent, be devoted to security. I recently had an idea, how to check which applications are using the Internet connection, where traffic can flow, through which addresses the connection goes, and much more. There are users who also ask this question.
Suppose you have an access point to which only you are connected, but you notice that the connection speed is somehow low, call your provider, they note that everything is fine or something similar. What if someone is connected to your network? You can try using the methods in this article to find out which programs that require an Internet connection it uses. In general, you can use these methods as you please.
Well, let's analyze?
Netstat command to analyze network activity
This way without using any programs, we just need the command line. Windows has a special netstat utility which deals with network analysis, let's use it.
It is desirable that the command line be run as administrator. In Windows 10, you can click on the Start menu right click mouse and select the appropriate item.
At the command line, enter the netstat command and see a lot of interesting information:
We see connections, including their ports, addresses, active and pending connections. This is certainly cool, but this is not enough for us. We would like to find out which program is using the network, for this, together with the command netstat, you can use the –b parameter, then the command will look like this:
| netstat –b |
Now the utility that uses the Internet will be visible in square brackets.
This is not the only parameter in this command, for a complete list, enter the command netstat –h .
But, as practice shows, many utilities command line do not give the information that I would like to see, and it’s not so convenient. Alternatively we will use third party software - TCPView.
Monitoring network activity with TCPView
You can download the program from here. You don't even need to install it, you just unpack it and run the utility. It is also free, but does not support Russian, but this is not particularly necessary, from this article you will understand how to use it.
So, TCPView utility monitors networks and shows in the form of a list all programs connected to the network, ports, addresses and connections.
In principle, everything is very clear here, but I will explain some points of the program:
- Column Process, of course, shows the name of the program or process.
- Column PID indicates the identifier of the process connected to the network.
- Column Protocol indicates the protocol of the process.
- Column Local adress- the local address of the process on this computer.
- Column Local port- local port.
- Column Remote adress indicates the address to which the program is connected.
- Column State- indicates the status of the connection.
- Where indicated Sent Packets and Rcvd Packets indicates the number of packets sent and received, the same with columns Bytes.
Even with the help of the program, you can right-click on the process and end it, or see where it is.
Address names, as shown in the image below, can be converted to a local address by pressing the hotkeys Ctrl + R.
If you see the lines different color, for example, green, then this means the start of a new connection, if red appears, then the connection is completed.
That's all the basic settings of the program, there are also crayons parameters, such as setting the font and saving the connection list.
If you like this program, be sure to use it. Experienced Users they will definitely find for what purposes to apply it.

Network monitoring software- it irreplaceable helpers every system administrator. They allow you to quickly respond to abnormal activity within the local network, to be aware of all network processes and, thus, to automate part of the administrator's routine activities: first of all, those related to providing network security... Let's see which programs for monitoring a local network are the most relevant in 2019.
This top is opened by our own development TNM 2 is an extremely affordable and powerful software solution for network monitoring activity of server machines, which displays perfect balance between convenience (in most free solutions missing GUI) and extensive functionality. One of the main programmable components of Total Network Monitor 2 are monitors, which perform checks as often as you need. The list of available checks is impressive. They allow you to track almost any parameter, from the availability of servers on the network to checking the status of services.
It is noteworthy that these objects are capable of independently eliminating the primary consequences of problems (that is, all this happens without the direct participation of the system administrator) - for example, restarting individual services or custom devices, activate antivirus, add new entries to the event log, etc. - in general, everything that the system administrator initially did manually.
As for reporting, it stores all the information associated with each check that was carried out by the selected monitor. The cost for 1 copy of this application is only 5,000 rubles.
Observium
Observium application, which is based on using SNMP protocol, allows not only to investigate the state of a network of any scale in real time, but also to analyze the level of its performance. This solution integrates with equipment from Cisco, Windows, Linux, HP, Juniper, Dell, FreeBSD, Brocade, Netscaler, NetApp and other vendors. Thanks to the perfectly crafted graphical interface This software provides system administrators with a variety of configuration options, from auto-discovery ranges to SNMP data required to gather information about a network.
They also get access to data about technical characteristics all equipment that is currently connected to the network. Observium can present all reports that are generated by analyzing the event log in the form of diagrams and graphs, clearly demonstrating the "weak" sides of the network. You can use both the demo version (which, in our experience, has a limited set of features) or the paid license, which has a yearly cost of £ 200.
Nagios
Nagios is an advanced web-based monitoring solution. It is by no means easy to learn, however, thanks to its rather large Internet community and well-developed documentation, it can be mastered in a few weeks.
With the help of Nagios, system administrators can remotely regulate the amount of load on user or higher-level equipment in the network hierarchy (switches, routers, servers), monitor the degree of utilization of memory reserves in databases, monitor the physical indicators of parts of network equipment (for example, the temperature of the motherboard , the combustion of which is one of the most frequent breakdowns in this area), etc.
When it comes to detecting network anomalies, Nagios automatically sends alert notifications to the address preset by the sysadmin - whether it's an email address or a mobile operator's phone number. A free demo version will be available to you for 60 days.
PRTG Network Monitor
Software component PRTG is compatible with Windows-based devices for network monitoring. It is not free (only a 30-day trial period is free), it is used not only for scanning devices that are this moment connected to a local network, but can also serve as an excellent assistant in detecting network attacks.
Among the most useful network services of PRTG: packet inspection, analysis and saving of statistical data to the database, viewing the network map in real time (the ability to obtain historical information about network behavior is also available), collection technical parameters about devices connected to the network, as well as an analysis of the load level on network hardware... Note that it is very easy to use - first of all, thanks to the intuitive graphical interface that can be opened using any browser. If necessary, the system administrator can also get remote access to the application through the web server.
Kismet
Kismet is a useful open-source application for sysadmins that can comprehensively analyze network traffic, detect anomalies in it, prevent crashes, and can be used with * NIX / Windows / Cygwin / macOS-based systems. Kismet is often used specifically to analyze wireless LANs based on the 802.11 b standard (including even networks with a hidden SSID).
With its help, you can easily find incorrectly configured and even illegally operating access points (which cybercriminals use to intercept traffic) and others. hidden devices that could potentially be "harmful" to your network. For these purposes, the application has a very well-developed ability to detect different types network attacks - both at the network level and at the level of communication channels. As soon as one or more attacks are detected, the system administrator will receive an alert and can take action to eliminate the threat.
WireShark
Free open source WireShark traffic analyzer provides its users with incredibly advanced functionality and is rightfully recognized as the exemplary solution in the field of network diagnostics. It integrates perfectly with * NIX / Windows / macOS based systems.
Instead of web interfaces and CLIs, which are not very well understood for beginners, in which you need to enter requests on a special programming language, this solution uses the GUI (although if you need to upgrade the set standard features WireShark, you can easily program them in Lua).
By deploying and configuring it once on your server, you have a centralized element for monitoring the smallest changes in network performance and network protocols. This way, you can detect and identify problems in the network early on.
NeDi
NeDi is completely free software that scans the network by MAC addresses (also among the valid search criteria there are IP addresses and DNS) and builds its own database from them. For work this software uses a web interface.
Thus, you can online watch all physical devices and their location within your local network (in fact, you will gain the ability to retrieve data about any network node - from its firmware to its configuration).
Some professionals use NeDi to find devices that are being used illegally (for example, stolen). This software uses CDP / LLDP protocols to connect to switches or routers. This is a very useful solution, albeit a tricky one to learn.
Zabbix
The monitoring system Zabbix is one-stop solution for open source network monitoring, which can be configured for individual network models... Basically, it is intended for systems that have a multi-server architecture (in particular, Zabbix integrates with Linux / FreeBSD / Windows servers).
This application allows you to simultaneously manage hundreds of network nodes, which makes it extremely effective tool in organizing the work of sysadmins working in large-scale enterprises. To deploy Zabbix on your local network, you will either need to run software agents(daemons), or use SNMP-protocol (or another protocol for secure remote access); and to manage, you will have to master the web interface in PHP.
In addition, this software provides a comprehensive set of tools for monitoring the health of the network hardware. Note that in order to fully experience all the benefits of this decision, your system administrator will have to have at least basic knowledge languages Perl or Python (or any other languages that can be shared with Zabbix).
10-Strike: Network Monitor
Network Monitor is a Russian-language web-based software solution that fully automates all aspects of network security. With its help, system administrators can prevent the spread of virus software over the local network, as well as determine the cause of all kinds of technical malfunctions associated with broken cables or failure of individual units of the network infrastructure.
In addition, this software online monitors temperature, voltage, disk space and other parameters via SNMP and WMI. Among its shortcomings are a fairly heavy load on the CPU (which the developer himself honestly warns about) and a high price.
Network olympus
And our list is closed by another of our programs. Unlike TNM, Network Olympus operates as a service and has a web interface, which gives it much more flexibility and ease of use. main feature- a script builder that allows you to move away from performing primitive checks that do not allow taking into account certain circumstances of device operation. With its help, you can organize monitoring schemes of any complexity in order to accurately identify problems and malfunctions, as well as automate the process of their elimination.
The scenario is based on a sensor, from which you can build logical chains, which, depending on the success of the test, will generate different notifications and actions aimed at solving your problems. Each element of the chain can be edited at any time and will immediately apply to all devices to which the script is assigned. All network activity will be monitored using the activity log and special reports.
If you have small network, then you do not need to buy a license - the program will work in free mode.
How to choose a program for network monitoring: results
Unambiguously choose the winner and name the best program monitoring your local network is difficult. But we are of the opinion that our Network Olympus product has many advantages and a very low entry threshold, because it does not require special training in order to start working with it. In addition, it does not have the disadvantages of open-source solutions, such as lack of updates and poor compatibility (both with the OS and with TX devices). Thus, thanks to such a solution, you will be able to monitor all events occurring within your local network and respond to them in a timely manner.
