2. ManageEngine OpManager – FREE TRIAL
“An infrastructure monitor that covers network device and server statuses”
While many monitoring systems separate network performance monitoring and server monitoring out into two separate packages, OpManager combines the two in one purchase. This tool also covers some key applications, such as virtualizations.
Key Features:
- Monitors networks and servers
- Uses SNMP
- Alerts for device faults
- Can run on AWS or Azure
Why do we recommend it?
ManageEngine OpManager implements performance monitoring for networks and servers. The service implements continuous network discovery that generates an inventory and network topology map. This system is based around the simple Network Management Protocol and it receives regular status reports from network devices, warning of potential faults.
OpManager uses a threshold system to identify when performance is likely to get impaired. There are many little problems that can soon stack up to bring performance to a level of impairment that users will notice. Catching these problems when they first arise gives you a chance to take action to head off disaster.
If a performance threshold gets crossed, the OpManager system generates an alert. This is shown in the service’s dashboard but it can also be forwarded to key personnel by SMS message or email.
OpManager is available in a free version. This has all of the functionality of the paid edition, but it is limited to monitoring only three devices. Those interested in the paid version have three choices of plans: Standard, Professional, and Enterprise. All versions are available for installation on Windows Server and Linux.
Who is it recommended for?
This package has a Free edition but it is limited to monitoring just three devices. The minimum coverage by the paid editions is for 25 devices. There is also an edition for managed service providers that includes a multi-tenant architecture.
Pros:
- Can monitor bandwidth consumption as well as alert to configuration changes that could impact network performance
- Can monitor bandwidth and resource consumption on the application level, and even drill down to identify specific users consuming the most resources
- Supports email, SMS, and webhook for numerous alerting channels
- Integrates well in the ManageEngine ecosystem with their other products
Cons:
- Takes time to fully explore all the options available in the ManageEngine software suite

3. Kiwi Syslog Server – FREE TOOL
“View and archive Syslog messages and SNMP traps from five sources in real-time”
Again, if I’m troubleshooting a particular network, site or node, I rely on a logging mechanism to audit and aid in troubleshooting. With Kiwi Syslog Server Free Edition you can collect, view and archive up to 5 sources including routers, computers or other devices. Logs may also be written to disk—either in one large file or split up by day or priority.
It’s easy to use, and absolutely free for small, focused logging engagements. You can view logs in real-time, gather stats, and even setup warnings and alerts. It’s not just Syslog messages, but also SNMP traps you can collect and analyze with Kiwi.
Key Features:
- Collects Syslog messages
- Catches SNMP traps
- Files Syslog messages
- Log forwarding
Why do we recommend it?
Kiwi Syslog Server helps you to centralize the gathering and storage of Sylog messages. What you do with those messages after that is up to you. However, remember that Sylog is a major source of data for SIEM systems. SNMP trap collection can be used to raise alerts over device component failure.
Who is it recommended for?
This tool is useful for any business. However, if you already have a log server as part of a SIEM system, you are probably already collecting Syslog messages and won’t need the Kiwi Syslog Server. This tool is not free forever but you can get it on a 14-day free trial.
Pros:
- Offers a freeware version for smaller networks
- Captures both syslog and SNMP traps, ensuring nothing is missed
- Interface is easy to use, and allows for quick filtering based on application, location, or custom grouping

4. Nagios
Nagios is a networking monitoring software solution. In fact, it’s a suite of solutions for monitoring network availability, analyzing data flows and security, as well as collecting logs for auditing. It’s completely open source and has a vibrant community of like-minded developers and administrators.
Key Features:
- Free and paid versions
- Runs on Linux or Docker
- Full stack monitoring
Why do we recommend it?
Look to Nagios Core for a free network monitoring system. This package won’t give you network traffic monitoring but it is a very competent network performance monitor. The tool will discover all of your devices and constantly monitor their statuses. The tool also monitors servers and applications.
With Nagios XI you can monitor everything from infrastructure to applications with granular detail. With Nagios Log Server, you can quickly sift through a central repository of audit logs, or setup triggers to alert you to critical events such as threats. And with Nagios Network Analyzer, dig deep into the health and integrity of your systems and network. Analyze flows, validate intent and troubleshoot with the lights on.
Who is it recommended for?
The Nagios Core package is very widely used and it is customizable. Businesses that need professional support packages for their software should look at the paid version, which is called Nagios XI. One problem is that neither version includes traffic analysis – that’s a separate package.
Pros:
- Open-source transparent tool
- Simple, yet informative interface
- Flexible alerting options support SMS and email
- Robust API backend makes it a great option for developers who want to integrate their own custom applications
- Very generous two-month trial period
Cons:
- Open-source version lacks quality support found
What I like most about Nagios is their straightforward approach to monitoring. They have multiple ways to represent data visually, which is another key interest of mine. Lastly, the built-in failover is wickedly cool if you start monitoring larger environments.
5. NTOPNG
“High-Speed Web-based Traffic Analysis and Flow Collection.”
Named after the popular top command in Unix, ntop shows network usage similarly to how top shows system usage. Ntopng, based on libpcap, is the next generation version of the original ntop. It was written in a portable manner, which gives it the flexibility to run on numerous platforms: Linux, Mac OSX, and Windows.
Key Features:
- Packet sniffer
- Protocol analyzer
- NetFlow analysis
Why do we recommend it?
NtopNG is a free package that can be used just to extract packets from a network or you can use its full capabilities to read in NetFlow data from network devices and produce graphs, charts, and alerts from it. The system has two paid versions for companies with money.
Web-based, ntopng allows you to view traffic data and gather reports regarding network status. You can use numerous criterion for sorting, including IP address, ports, Layer 7 protocols, BGP AS, and so on. You can even do long-term reports to collect metrics such as throughput over time.
Who is it recommended for?
This free package is suitable for any network manager and is particularly useful for those who want to perform packet-level analysis. It can also be used to aggregate traffic data for alert creation. The service is available in two higher paid editions, called Pro and Enterprise.
Pros:
- Open-source project with full transparency
- Free version available alongside the enterprise version
- Special licensing options for nonprofits and educational institutions
Cons:
- User interface is easy to use, but could be improved upon
I personally use this tool to generate detailed host-based reports showing applications latency, RTT, TCP statistics like retransmissions, out-of-orders, and zero windows.
6. SolarWinds TFTP Server – FREE TOOL
At some point in your day-to-day as a network administrator, you’ll have to transfer a configuration file or image file to a router.
TFTP has been the easy go-to for this task for many years, and although alternative protocols are out there, good chances are you’ll still run into the case where TFTP is just easier.
This is the reason why I always have a TFTP server app loaded on my laptop.
My personal choice for this software is SolarWinds TFTP Server.
Key Features:
- Suitable for network file transfers
- Lightweight
- Use for configuration management
Why do we recommend it?
SolarWinds TFTP Server is a lightweight tool, as any TFTP server should be by the very nature of the Trivial File Transfer Protocol. The tool is useful only for internal network use because TFTP doesn’t include any security measures. The tool shouldn’t be used to transfer files across the internet.
We’ve written about it in the past and it still holds its rank. It’s a multi-threaded, reliable and works like a champ. Best of all, it’s free.
As a bonus little feature, you can actually authorize specific IPs or ranges to limit sending and receiving directly to the server for advanced security.
And if you’re doing this regularly or from a central server, run it as a service for 24×7 availability. Get the 100% free tool.
Who is it recommended for?
Any network manager will find a use for this tool. TFTP is regularly used to move configuration images from network devices to storage and back again in case of configuration tampering. Thus, you would use this system as part of a network configuration management strategy. This software runs on Windows Server.
Pros:
- Completely free
- Simple interface, no clutter, fluff, or advertisements
- Available as a Windows service, allowing tasks to be scheduled
- Can authorize single IP addresses, or an entire range
- Lightweight install, uses minimal resources
Cons:
- Like all TFTP servers, you will still need technical experience to set the service up properly
Download: https://www.solarwinds.com/free-tools/free-tftp-server
7. SolarWinds SFTP/SCP Server – FREE TOOL
Those alternative protocols I mentioned before? SFTP and SCP are two of them.
If you have the capability to use the secure protocols instead of TFTP, do it, just make sure you have trusted software like SolarWinds SFTP/SCP Server.
Like the TFTP Server software, SolarWinds SFTP/SCP Server is multi-threaded and commonly used to upload and download executable images and back-up configurations for routers and switches.
Key Features:
- Secure file movements
- Runs on Windows
- IP address blocking
Why do we recommend it?
The free SolarWinds SFTP/SCP Server is a handy tool that can be used for a range of purposes. For example, it is safe for use to move files across the internet as well as around the network. It would also be possible to let end users get access to the tool for regular file transfer tasks.
Who is it recommended for?
This is a useful tool for any business. The network administrator can restrict the IP addresses that the tool can send files to, which is a useful security measure if the tool is going to be given to end users for regular file movement tasks. It can also be used for network administration tasks.
Pros:
- Can support large volumes of file transfers
- Free to use
- Has an advanced user interface, helpful for managing multiple file transfer locations or partners
- Can automatically sync files, helping keep both parties updated
- Built for business use, EDI, backups, etc

8. Network Configuration Manager – FREE TRIAL
Assuming you need one of these tools, it’s likely you’re transferring config or images files to/from network devices.
If you’ve never checked it out, I highly recommend giving SolarWinds Network Configuration Manager a whirl.
It’s Free to try but does have a cost associated past the trial period.
Key Features:
- Backup network device configurations
- Scan for changes
- Restore authorized configurations
Why do we recommend it?
The Network Configuration Manager is a useful tool for network device security. You can use it to standardize the settings of your switches by setting up one, taking an image and then applying that image to all devices. Store an image for backup and the tool will scan for unauthorized changes, reapplying the definitive settings if a change is detected.
Who is it recommended for?
This is not a free tool but you can use it for 30 days for free during the trial period. The system is most likely to appeal to large businesses that have many network devices to manage. The software package runs on Windows Server.

Download: https://www.solarwinds.com/free-tools/port-scanner
10. Wireshark / Tshark
This is a no-brainer for most but needs to be mentioned for integrity’s sake.
Wireshark is an unparalleled network protocol analyzer, and honestly, one of the best free network tools ever made.
When you’re troubleshooting an issue and actually need to get into the weeds to find out what’s going on – this is your microscope. Never leave home without it!
Key Features:
- Packet capture
- Packet type color coding
- Filters and query language
Why do we recommend it?
Wireshark is a great package analysis tool. It can be used for performance analysis and security scanning, and it is also frequently used by hackers and penetration testers. This is a free tool and it has its own query language, so the tool has a highly skilled and extensive user community of network technicians.
Who is it recommended for?
All network managers should get this tool. If you have done a network management or cybersecurity course, you have probably already been taught how to use Wireshark and you probably already have it. The proprietary filtering and query language takes a lot of time to learn.
Pros:
- Massive open-source community keeps the software updated and new features are added periodically
- Built by network professionals, for network professionals
- Can save captured packet data for further analysis or archival purposes
Cons:
- Collects massive amounts of data by default – must be sorted and filtered
If you’re looking for some command-line capturing, or maybe you want to programmatically trigger packet captures, don’t forget to check out TShark. It’s included with Wireshark, and totally awesome.
11. iPerf / JPerf
Between any two nodes is a network – be it vast or small.
A simple ping between the two nodes is only good for general reachability and understanding the round-trip time for the small packets.
If you want to measure actually achievable bandwidth, you need another tool such as iPerf.
Key Features:
- Notes total capacity and usage per link
- Identifies capacity problems
- Helps with capacity planning
Why do we recommend it?
iPerf gives you a traffic sampling service and JPerf is a GUI version of the tool. You can check on bandwidth availability with this tool, letting it run tests on capacity utilization periodically. This is a useful service that you can set up to run in the background and trigger alerts.
iPerf3 is the latest iteration of this tool. You run the client on two ends of a network, configuring the parameters needed to measure performance. It supports tuning of many parameters related to timing, buffers, and protocols (TCP, UDP, SCTP with IPv4 and IPv6). Upon execution, it actively measures and reports on bandwidth, loss, latency, jitter, and so on. You can initiate multiple simultaneous connections to truly simulate load across the network. Very handy tool!
Who is it recommended for?
This is a rudimentary traffic capacity checker and it would be suitable for a small business network. The tool essentially checks on a path to a destination, which means that you would have to launch a lot of queries to get all paths across your network test simultaneously.
If you’re more of a GUI person, check out Jperf. It’s up there in age but still works like a champ.
12. Nmap / Zenmap
I personally use Nmap at least once a week. Almost verbatim from their website: Nmap (Network Mapper) is a security scanner used to discover hosts and services on a computer network, thus creating a “map” of the network. To accomplish its goal, Nmap sends specially crafted packets to the target host and then analyzes the responses.
Key Features:
- Powerful command line tool
- GUI with Zenmap
- Probe a network
Why do we recommend it?
Nmap is a command line tool for network exploration. It is a little dated but it is still one of the main tools use by network technicians for network investigations. It is a single command but it can perform a lot of different queries depending on which options you implement with it.
Nmap provides an incredible number of features for probing networks, including host discovery, service discovery and operating system detection. These features are extensible by scripts that provide more advanced service detection, vulnerability detection, and other features. In fact, Nmap is used in the backend for various security assessment tools such as Nexpose.
Who is it recommended for?
Nmap is used by network technicians, hackers, and penetration testers. It is a very highly respected tool and you will be taught how to use it if you do a network management or cybersecurity course. Learn what all the options do to get the best out of the system.
Pros:
- Doubles as a security tool, allowing administrators to discover open ports, and applications communicating over ports that are suspicious
- Massive open-source community, is one of the most popular free security tools available
- Offers a GUI version, Zenmap, which lowers the barrier to entry for new users
- Syntax is straightforward and not difficult to learn for most users
Cons:
- Nmap can have a steep learning curve for new users
- Might be overkill for simpler troubleshooting tasks
Again, if you’re more a fan of GUIs, make sure the download the bundle with Zenmap.
13. Paessler SNMP Tester
SNMP can be hard. This is why you need a good tester. There are a few out there, but I’ve found great success with Paessler’s SNMP tester.
Key Features:
- Standalone utility
- Checks on SNMP
- Also tests network links
Why do we recommend it?
Paessler SNMP Tester is a useful tool for network managers who are setting up a monitoring system. If you want to check whether an SNMP device agent is turned on, you can use this tool. The tool is free to use and it runs on Windows.
Who is it recommended for?
An extra benefit of the tool is that you can check whether a device that you expect to be using a specific IP address is actually there. Paessler also offers PRTG, which is a much larger SNMP-based tool and that package will discover all of your SNMP-enabled devices.
Pros:
- Great tool for prepping devices for a SIEM implementation or other agent-based monitoring
- Super lightweight, doesn’t take up much space or system resources
- Works well in tandem with other PRTG sensors
Cons:
- PRTG is designed for network administrators and requires networking knowledge to fully utilize
The idea of this program is to have a tool that enables the user to debug SNMP activities in order to find communication and/or data problems in SNMP monitoring configurations. Are your devices configured properly? Are you using the correct keys? Use this tool to validate if your SNMP configuration will function with programs like PRTG Network Monitor.
14. Angry IP Scanner
Angry IP scanner is an open-source, multi-threaded IP address and port scanner. Similar to Nmap, and used by millions, it’s become a standard tool for network admins. Angry IP Scanner first rapidly pings, then checks port status, then starts resolving hostnames, gathering MAC addresses, OSs and whatever it can discern based on the data gathered. It can collect NetBIOS info like workgroup and domain names, as well as logged-in users if you happen to have to privileged rights to retrieve this information. Like Nmap, it’s extensible with plugins. Scanning results can be saved to CSV, TXT, XML or IP-Port list files.
Key Features:
- IP scanner
- Port checker
- Ping tester
Why do we recommend it?
Angry IP Scanner is a very popular free tool and it has been downloaded 30 million times. The utility will scan an IP address range and you can make the range wide enough so that the tool will discover all of the devices on your network. You can also choose to focus on just one device.
Who is it recommended for?
This tool is useful for anyone. It has a wide appeal because it will run on Windows, macOS, and Linux. The tool has a nice color-coded circle at the beginning of each line in its results that makes instant response status recognition possible. That rating refers to the results of a Ping test to that device.
Pros:
- One of the easiest tools to use on the market
- Great for small networks and home use
- Provides simple log outputs
- Lightweight tool – uses little system resources
Cons:
- Not ideal for continuous monitoring
- Lacks graphing capabilities
Runs on Windows, Mac, and Linux. Get it here.

15. Ansible
“No one likes repetitive tasks.”
Ansible is a simple and powerful automation engine with the goal of reducing repetition by automating tasks. It’s vendor agnostic, programmable and relatively easy to learn. The folks at Ansible believe that automation shouldn’t be more complex than the tasks it’s replacing.
Key Features:
- Task automation
- Flexible tool
- Time or event triggers
Why do we recommend it?
Red Hat Enterprise Ansible isn’t specifically a network management tool, it is a workload automation system that you can use to automate network administration tasks. The abilities of this tool extend to managing Active Directory, processing data with file movements, or data validation checks.
From a network perspective, I like this tool for generating configuration files based on my custom templates. I can quickly build “playbooks” for a large number of scenarios, ensuring that my configuration files are properly built based upon my standards and that my network devices are configured accordingly.
Who is it recommended for?
This system is able to implement processes on cloud platforms and different sites, not just on a single LAN. This makes it a very powerful tool for system designers as well as for network managers. The only problem is that you need to dedicate time to learning the tool in order to construct tools to save you time.
Pros:
- Simple minimalistic interface – makes it easy to view key metrics
- Leverages playbooks to automate device configuration and deployments
- Supports numerous vendors, with plenty of community-built template
- Completely open source and free
Cons:
- Is a full-service monitoring platform that can take time to fully explore all options available
- Open source tool that might not be the best fit for all network environments
If you want to get more with a GUI, check out Ansible Tower. Super clean.

Why do we recommend it?
Netmiko Is a library of tools, written in PHP that lets you set up a secure connection to one of your network devices. You can contact your own network devices across your network anyway, so this tool would only be of use to connect to devices on another site, or to your single site from your home.
Who is it recommended for?
Anyone can use this tool to test switches and run show commands to gather settings. The package doesn’t add much to the usual switch command line service other than creating a secure connection from a remote location.
Pros:
- Lightweight SHH-based tool
- Ideal for users who are looking for a CLI automation tool
- Features an extensive library of supported vendors
Cons:
- Not as beginner-friendly as other tools that offer both GUI and CLI options

- Code formatting
Why do we recommend it?
You are always going to need a lightweight editor to write scripts and programs and these three free options are worth looking into. Notepad++, UltraEdit, and Sublime Text don’t use much processor power, so you won’t drag down your CPU by having it open or even having multiple instances open simultaneously.
Who is it recommended for?
The tools are useful to have to hand. These are just three examples of text editors that are worth using. Take a look for others. For example, you might prefer a system that is based online or one that is portable that you can store on a memory stick.
Pros:
- Great for editing codes, PHP files, and configurations
- Can highlight syntax and help streamline edits
- Is aesthetically better than Notepad
Cons:
- Not a dedicated monitoring tool
We use Notepad++ Every single day – whether we’re editing PHP files, Nagios Configs, or Searching through Multiple files for a string or Text at the same time, Notepad++ is the best text-editor on the market!
19. Cygwin
If you’ve ever used Linux, you’ve become familiar with useful commands such as ‘grep’, ‘ls’, ‘top’, ‘df’, ‘pwd’ and so on. In the Windows world, we are missing some of these commands, and we have them, it’s written in some other non-intuitive syntax. Wouldn’t it be great to have Linux commands and applets in Window? Enter Cygwin.
Key Features:
- A collection of Linux tools
- For use on Windows
- Open source project
Why do we recommend it?
Cygwin is an ever-expanding source of utilities. Although the tool provides a way to run Linux commands on Windows it isn’t a virtual platform to run any Linux software on Windows. So, the package has limitations and isn’t quite as widely useful as many people think.
Who is it recommended for?
Cgywin provides Linux utilities for Windows. If you are used to working on Linux and now have to use Windows computers, you will miss the old commands that you regularly use. So, in this case, you would welcome the opportunity to get these familiar commands back.
Pros:
- Open-source transparent project
- Allows Linux applications to run inside Windows through recompling
- Is one of the only few backwards compatible options from Linux to Windows
Cons:
- Not as user-friendly as other options, has a steep learning curve
- Recompiling some applications from Linux to Windows doesn’t always work on the first attempt
Cygwin is a large collection of GNU and Open Source tools, which provide functionality similar to a Linux distribution on Windows. Not only can you run familiar commands, but also you can load (similar to apt-get or yum) various Linux tools. Some favorites of mine are wget and curl. If I’m running Windows, I’m running Cygwin.
20. Draw.io
I love Visio. It’s undoubtedly the best tool for designing network diagrams. However, it can be expensive, and it only runs on Windows. As a Mac user, I run a Windows VM just so I can use Microsoft Visio. While this does function, I’ve recently started using Draw.io, a browser-based diagramming application. It’s awesome!
Key Features:
- Online tool
- No account needed
- Store to your own location
Why do we recommend it?
Draw.io gives you a designer canvas to create any type of chart or diagram and that includes network maps. You can’t import automated discovery data into this tool, so you have to draw up your maps manually. You don’t need to set up an account and you can save your designs to your own cloud drive account.
Who is it recommended for?
Draw.io is one of the few free diagramming tools that you can access online. It doesn’t include storage space but you just save to your own account on Google Drive, OneDrive, Dropbox, GitLab, GitHub, or your own hard drive.
Pros:
- Cloud-based diagram creations
- Easy to use – even if you’re not great at design
- Offers hundreds of different icons
Cons:
- Not a live reflection of your network – better for planning and presentation
Whether you’re building an engineering diagram or a network diagram, Draw.io has tons of templates to get you started. It connects to online storage environments like Dropbox and Google Drive for real-time saving. No more losing data. Again, it’s absolutely free, and something you can rely on for cloud-based diagrams that are shareable and exportable.
