Routers - Uses And Various Types

Written by oneself on 3:04 PM

By: Pencil Writer

Router is a hardware which is used for sharing internet access through sharing networks within local area. These routers have designed with the potential to transfer signals from a single point to the multiple exact destinations. It is essential to get a router for sharing your application and internet within your LAN. While you choose a router, it is better to keep certain considerations like modems, types and the budget.

Types of Routers

Cords are used for getting connectivity. The wiring process and maintenance of cords are not easy. Routers can be classified in to two namely cable routers and wireless routers. When you use routers for sharing internet from a server to multiple client systems, it is essential to consider about the usage of cords.

Corded Routers

When the necessary cords are already placed properly with the systems, there is no need of buying wireless routers. Corded routers can offer high quality data transmission. If the cords are placed very close to each other, you can save the length of the cable as well as money. Before using the corded routers, it is essential to check the specifications. Therefore you can make sure the ability to share web access in your office or home.

Wireless Routers

As these routers do not use cords to connect system with each other to interact or share data. It is easy to get internet access for all your computers without using a single wire by using these wireless routers. You can be free from wiring problems. These types of wire-free routers have functioned with the support of radio waves. It uses aerials for transmitting signals. These kinds of routers offer high speed internet connection. These wireless routers are also known as wire-free routers.

What is the advantage of routers?

Modem is a main hardware used for getting internet access. But most of the users prefer routers in stead of modem. It has featured with an added advantage of getting access by using a single modem to all the computers. When you use modem, you have to use one modem for every single system. Suppose you have 7 systems, then you have to get 7 modems to get internet access. But when you choose router, there is no need to buy each one for all the systems in your local network.

Remote Desktop Protocol (RDP) Port Forwarding

Written by oneself on 4:25 AM

By Jason Fortner

One thing that I love about all news windows products is the remote desktop features. I previously used PCAnywhere but I find that remote desktop is now almost as good, would like to see a file transfer like PCAnywhere has, but remote desktop is free so that is a plus for it.

One of the tasks that I face with my network setup is forwarding ports through my router. There are two issues that I came across when dealing with the RDP forwarding. The first was what is the port number of RDP. With a quick search on Google I found that the standard RDP port is 3389.

Now that you have the port number you can simply go into your router and forward that port through and after enabling your remote desktop feature it will work from outside your network as long as you either know your IP address or have a dynamic dns service like I use. To enable remote desktop in Windows XP and Windows 2003 go to the start menu, find the my computer icon and right click on it. Select the properties option in the drop down list and then click on the remote tag in the window that appears. There you will see the two check boxes, check the second box, and then click on the remote user button. Make sure that the users you want to have access are in the list and then click ok until you have exitted all of the windows. RDP is now enabled on your machine.

So this simple setup would have worked for my network but the issue then became I have several servers that I want access to along with my desktop. Now I could just remote to my desktop and then remote to the other machines from there since they are all on the local network. This would create a lot of data that needed to be transferred though, with limited upstream speeds on your broadband connection you don't want this, and will cause performance issues with RDP. So I had two options, I could change the registry entry like was stated in the article. I will paste that fix here just in case that page has an issue at some point:

***** WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

You can use the Remote Desktop feature in Windows XP Professional to connect to your computer from another, remote computer. WARNING: The Remote Assistance feature in Windows XP may not work properly if you change the listening port. To change the port that Remote Desktop listens on:

Start Registry Editor (Regedt32.exe).

Locate the following key in the registry:

HKEY_LOCAL_MACHINESystemCurrentControlSetControlTerminalServerWinStationsRDP-TcpPortNumber

On the Edit menu, click Modify, click Decimal, type the new port number, and then click OK. Quit Registry Editor.

NOTE: When you try to connect to this computer by using the Remote Desktop connection, you must type the new port.

Keywords: kbhowto kbnetwork KB306759

Technology: kbrdcMac100 kbrdcsearch kbrdcWin100 kbWinXPPro kbWinXPPro64bit kbWinXPProSearch kbWinXPSearch kbZNotKeyword

*****

The other option I had was to go into my router and specify another external port number and then point that port to the 3398 on the IP address of the machine I wanted to go to. I chose this second option as it was less time consuming and did the trick for me. One appealing thing about the ability to change the port number of RDP is security. If you leave the standard port number then anyone will know to check that port to see if you have Remote Desktop enabled and potentially compromise your network. Let me know if there are any issues with the registry fix though and if there are I will just remove it from this article.

Top 5 Tips For Protecting Your Computer

Top 5 Tips For Protecting Your Computer

Do you ever feel like you know just enough about PC Security to be dangerous? Let's see if we can fill in some of the gaps with the latest info from PC Security experts.

Today, more and more people are using their computers for everything from communication to online banking and investing, to internet shopping.

As we do these things on a more regular basis, we unknowingly open ourselves up to a multitude of online threats to our PC's security. These include but are not limited to potential hackers, attackers and crackers. In addition there are pieces of software, malware, adware and scripts containing Trojans and other such virus like nasties that are all intent on soliciting some form of information about us which may already be contained in personal files on our PC systems.

1. Get a Router. If your broadband connection is through some form of modem (normally USB or cable) supplied to you by your ISP (Internet Service Provider), make sure you attach this to a Router and then attach that Router to your PC. Many people just attach the modem to their PC and then rely on Anti-Virus software to protect them. This is simply not enough nowadays, and they will surely have a problem somewhere down the line.

2. Make regular Backups of your data and important information and keep it in a safe place that is separate from your computer. Nowadays there are a lot of different ways to achieve this, especially with the advent of DVD writers and low cost hard disks which enable a lot of data to be backed up and stored "offline".

3. Keep your operating system, web browser and software updated frequently. If you have a Windows operating system, start by going to www.windowsupdate.microsoft.com and running the update wizard. This program will help you find the latest patches for your Windows computer. Also go to www.officeupdate.microsoft.com and locate possible patches for your Office programs. If you have Windows XP service pack2 installed (and it is recommended that you do, because it contains inbuilt security fixes) you can use the Security Center from the Control Panel to turn "Automatic Updates" on. This will keep your system updated with all the latest patches and fixes that Microsoft releases.

4. Make sure you install a firewall. Without a good firewall, viruses, worms, Trojans, malware and adware can all easily access your computer from the Internet. Consideration should be given to the benefits and differences between hardware and software based firewall programs. Of course, if you use a router (which is recommended) this will already have a firewall built into it, and this can work in addition to any software firewall you choose to install on your PC.

5. Check your internet browser and email client settings for optimum security. Why should you do this? Active-X and JavaScript are often used by hackers to plant malicious programs into your computers. While cookies are relatively harmless in terms of security concerns, they do still track your movements on the Internet to build a profile of you. At a minimum set your security setting for the "Internet zone" to High, and your "trusted sites zone" to Medium Low.

I hope that reading the above information was both enjoyable and educational for you. Your learning process should be ongoing--the more you understand about any subject, the more you will be able to share with others.
