The BF contributed $40 million dollars to local non-profits in its first 38 years and $4.6 million to UAB employees through the Employee Emergency Assistance Program. In its first 5 years, Blazer Kitchen received $517,000.

Netstat (Network Statistics) is a command-line tool for monitoring and troubleshooting computer network issues. This tool shows you all your device’s connections in as much detail as you need.

With Netstat, you can view all your connections and their ports and stats. This information is valuable when setting up or fixing your connectivity. This article will introduce you to the Netstat command and the main parameters for filtering information displayed about your connections.

We’ll explore the following syllabus in this section:

1. How to use the Netstat command.
2. Use netstat parameters to filter connection information.
3. Combining Netstat parameters.

Join me as we go through the above syllabus to help you better understand this tool and learn how to use it to troubleshoot your network issues.

1] How to use the netstat command

Click on the Start button and search for Command Prompt. Open Command Prompt with elevated privileges by right-clicking on it and selecting the Run as administrator option.

You can open Netstat by typing the following command and pressing ENTER:

netstat

You may not understand what the columns mean if you’re new to networking.

• Proto: The network protocol. It could be either TCP or UDP.
• Local Address: The IP addresses and ports of your computer’s network interfaces for the given connections.
• Foreign Address: The IP addresses and port names of the remote devices.
• State: Indicates the state of the connection. For example, find out active and closed connections.

The netstat command shows you your active connections and their details. However, you’d notice that the foreign address column prints the IP address and port names.

To show the connections’ port numbers instead of the port names next to the IP addresses, use the following command:

netstat -n

Further, the system can disconnect or connect to networks, and the network details can change at intervals. Hence, we can use the following command to refresh the netstat network details at intervals using this command:

netstat -n 5

To stop the refreshing, press the CTRL + C key combination.

NOTE: The 5 in the command above refreshes the command every 5 seconds. If you wish to increase or shorten the interval, you can modify this value.

2] Use netstat parameters to filter connection information

The netstat command is a powerful command that can show you every detail about your device’s connections. Explore the most commonly used netstat parameters to find specific network details.

• Display active and inactive connections

Show the networks that are active or inactive.

netstat -a

• Display applications information

List all applications that are associated with the connections.

netstat -b

• View network adapter stats

Show statistics on incoming and outgoing network packets.

netstat -e

• Display foreign addresses’ fully qualified domain name (FQDNS)

If you don’t want to see the port numbers or names, the following netstat parameter will show your foreign addresses’ fully qualified domain names.

netstat -f

• Show port numbers instead of names

Change the foreign address port names to port numbers.

netstat -n

Similar to netstat, and it has an extra column for every connection’s Process ID (PID).

netstat -o

• Filter connections by protocol

Display the connections for the protocol you specify – UDP, TCP, tcpv6, or udpv6.

netstat -p udp

NOTE: You should change the udp part to the protocol whose connections you want to view.

• View non-listening and listing port

Show connections and their listening and bound non-listening ports.

netstat -q

Categorize networks by available protocols – UDP, TCP, ICMP, IPv4, and IPv6.

netstat -s

Show the routing table of your current network. It lists every route to the destination and matrix available on your system. Similar to the route print command.

netstat -r

• Display offload state connections

Show a list of connection offload states of your current connection.

netstat -t

• See NetworkDirect connections

Shows all NetworkDirect connections.

netstat -x

• Display connection Templates

Show your networks’ TCP connection templates.

netstat -y

3] Combining Netstat parameters

You can further filter the Netstat parameters to show you information about your connections any way you want. From the above commands, you only have to add a second parameter to show a combined view.

For instance, you can combine the -s and -e parameters to view the statistics for every protocol. This way, you can combine other parameters to get the desired results.

When mixing multiple Netstat parameters, you don’t need to include two dashes (-). You can use one dash (-) and append the parameter letters without a second one.

For example, instead of typing the following command:

netstat -s -e

You can write it as:

netstat - se

If you forget the parameters, a quick way to remember them is by asking netstat to help. Simply run the following command:

netstat /?

To stop the netstat query process, press the CTRL + C key combination.

Can we check network connectivity using netstat?

We can check network connectivity using the netstat or network statistics command. This allows us to see active network connections and their status. The tool can view incoming and outgoing network connections, routing tables, port listening, and usage statistics. This command can be handy for network administrators when troubleshooting network issues. By understanding how to use this command, you can quickly and efficiently diagnose problems with your network.

How do I see network issues in Windows?

You can check your network connection status in Windows quickly and easily. Select the Start button to do so and type “settings” into the search bar. Once you’re in the Settings menu, select “Network & internet.” The status of your network connection will be displayed at the top of the page. If you’re having trouble connecting to the internet, this is a helpful first step in troubleshooting the issue. You also check quickly, and if you see the wifi icon missing, you have a network issue.

An test proctor will begin studying test instructions approximately 15 minutes before the test start time. Students must be in the test room with their test at this time. If taking the test on a laptop, it must be booted up and have passed the security check. Hand writers must not have a laptop with them in an test room, unless otherwise allowed according to the professor’s instructions. A student entering the test room after the proctor begins studying instructions will not receive additional time for booting up their laptop, passing the security check, and/or studying test instructions.

When instructed by the proctor, write your test number on the cover page of your exam, bluebooks, and any scratch paper you turn in as part of your exam. Handwritten test answers must be written in blue books in blue or black ink. Number the bluebooks you use (1 of 1, 1 of 2, 2 of 2, etc.). Proctors will allow time to read the professor’s instructions. Other than counting the number of pages of the exam, students are not permitted to turn the page of an test past the instructions page until the proctor instructs them to do so.

When taking a closed-book exam, no books, outlines, book bags, purses, or scratch paper (other than the scratch paper provided) may be at your seat during the exam. These items must be left outside of the test room or in the front or sides of the test room. Students may not begin to write anything, including on scratch paper, before the proctor begins a closed-book exam.

Students taking in-class exams are prohibited from having any electronic communication device, other than a laptop as allowed per the professor's instructions, during the exam. Cell phones and smart watches must be turned off during the test and placed in a bag or backpack. Violations of this rule may be considered an Honor Code violation. A clock in each test room will be the official timekeeper for the exam.

Non-alcoholic beverages are permitted in test rooms; however, the container must have a lid.

After the test instructions have been read and the test begins, the proctor will remain in the room. Any student who has a question or problem during an test should see the proctor.

Students may use the restroom or take a break during an exam. However, all test materials must be left in the test room and no additional time will be given. Students must sign in and out at the front of the room with the proctor.

A typical examination question in Mathematics will have several parts to it. Some parts (most usually at the beginning of the question) test your knowledge, by asking you to reproduce "bookwork", i.e. material presented in the lectures. Really, these parts test how well you've revised. Occasionally, especially in certain more advanced courses, there are entire questions that are bookwork. In some courses, some pieces of bookwork come up in the test almost every year. In other courses, hardly any bookwork is set explicitly.

Tip: Figure out which pieces of bookwork come up most frequently, and make sure you can answer those questions easily and quickly.

You would be surprised how many poor attempts at routine bookwork questions we see every year. These are the parts of the questions that we expect students to be able to do.

Other parts of examination questions involve a "problem". In a "Methods" course, this will typically involve you applying a known technique from the course, and again this is something we expect you to be able to do. In a Pure Mathematics course, you might be asked to prove a result, or to apply a result in a particular setting.

Tip: Sometimes (but certainly not always!), the first part of the question is intended as a big hint as to how you should approach the second part.

Many test questions, especially those that are otherwise very routine, have a last part (a "rider") which is more challenging than the rest of the question. This is quite deliberate, and the intention is to test whether you've really understood the material.

Tip: Do try all the riders (they're not always so hard after all!) but don't waste too much time on them in an test if there are other things you can tackle instead.

Students sometimes seem to be annoyed that they have to do something clever to get 100% on a question. Don't forget, in many other subjects it's practically impossible to score 100% on a question!

Tip: Make sure you've answered all the parts of the question. Sometimes you're asked to do seven or eight things, and it's easy to overlook one.

Calculate How Much Life Insurance You Need

A no-exam life insurance policy may not be able to provide the full coverage amount you need, especially if you’re looking to cover many working years or the years of raising a family.

Before you start getting life insurance quotes, calculate how much life insurance you need. A no-exam policy alone may not be able to provide sufficient coverage.

Assess Your Chances Before You Apply

Getting life insurance without a long application process is appealing, but don’t jump into a no-exam life insurance application without understanding your chances of getting approved. Many no-exam policies require very good or excellent health for approval. A denial goes on your insurance record and could hinder future applications.

Don’t be surprised if you end up doing a more traditional application process, including a life insurance medical exam if you’ve had some health issues.

Look Beyond the Cost

Of course you don’t want to overpay for life insurance, but research more than cost. There are coverage options that can be very valuable long after you buy the policy, such as the option to convert term life to permanent life insurance. Also, look at whether there’s an accelerated death benefit, which gives you access to money from your own death benefit if you become terminally ill.

Be Truthful On the Application

No matter what type of life insurance you’re applying for, be thorough and truthful on the application.

“Pay attention to each question carefully and be ready to respond with information around specific medical conditions you have. Giving more detailed information will help streamline the process as well as get a more accurate underwriting decision,” says Tavan of Legal & General America.

Intentional misrepresentations can lead to application denials or, worse, denial of a claim after you pass away. Life insurance companies have many ways to verify application information. Technology on the backend allows them to verify data from additional sources.

Have a Plan in Case of a Rejection

If the company rejects you for no-exam life insurance because of your health, don’t give up your life insurance search. If you need life insurance, you likely have other routes.

• Be prepared to go through a more traditional underwriting process that involves a life insurance medical exam.
• Work with an experienced life insurance agent who can identify insurers known to be more friendly to your specific health conditions.
• An experienced life insurance agent can shop around your application anonymously so that you don’t risk another rejection.

Those with children of school-going age will know that November is filled with exam stress and deadline pressures. Creating a quiet, distraction-free space in the home can not only help them through this stressful season, but it could also add value to the home.    

Home tips for test time  

“Homes with a study space are in high demand following the pandemic. Whether the space is used for those who work remotely or for their children as a dedicated homework station and study space, having a secluded room in the home can be a good value addition to any home,” says Regional Director and CEO of RE/MAX of Southern Africa, Adrian Goslett.

To help homeowners prepare their homes for test season, RE/MAX of Southern Africa shares the following tips…

Dedicate a room to studying

Research shows that one’s bedroom should be a place for sleeping and nothing more to promote good sleeping habits. A lack of sleep leads to lowered concentration and a reduced ability to retain information, so a child’s ability to study can Improve simply by giving them their own study space in the home. If budget allows, add a room or renovate an existing space to form a dedicated study at home, or look for homes with a separate designated study area if you are in the market to buy.

Fix lighting & ventilation

Air quality, ventilation, and lighting of the space can all contribute towards a better studying environment. Poorly lit rooms can cause strain on the eyes when reading, which could cause a child to grow tired quickly. The brain uses about three times as much oxygen as muscles in the body do, which is why rooms without good ventilation can reduce a child’s learning capacity. Trim back big trees or bushes that might be blocking natural light or ventilation to the study. Replace small windows or faulty windows that can no longer open. Also, upgrade the lighting fixtures to ensure the room has adequate lighting.

Minimise distractions

Think about how many distractions the room in question might have and do your best to manage these. If the room is too close to the noisiest rooms in the home, then it might be worth sound-proofing the room or upgrading the room’s insulation by adding rugs and other sound-dampening décor.

As a final piece of advice, Goslett suggests that homeowners speak to a local RE/MAX Office if they are hoping to find a home with its own study or if they are hoping to upgrade their home to add on a study.

“As experts in their local markets, real estate professionals are best equipped to provide expert advice on what renovations will add the most value and what buyers are willing to pay for a home with these features. They can also provide guidance as to what other homes with these features are selling for in the area,” Goslett concludes.
