  • Securing the D-Link DIR-628 Wireless Router

    Securing the D-Link DIR-628 Wireless Router

    I have written a few guides about securing a wireless router. All the guides in the past were for 802.11g routers, so the routers have been around for many years, and are quite common. This guide will concentrate on a newer router, with many more options.

    The 802.11n proposed standard is becoming much more commonly supported in various networking devices, and has been for the last few years. This post will provide step-by-step instructions for securing an 802.11n device: the D-Link DIR-628 wireless router.

  • Securing the Linksys WRT54GL Wireless-G Router

    Securing the Linksys WRT54GL Wireless-G Router

    Two of the most popular posts on Technically Easy has to do with securing the Linksys WRT54G and D-Link DI-524 wireless routers. With many people using wireless routers at home, it becomes more important to secure the connection to the router form a computer. When I turn on my laptop at home, I can see at least five wireless networks (all secured).

    I decided to write another “how to secure a wireless router” guide, to help those who may not have one of the two routers listed above. This guide will describe the steps you need to take to secure the Linksys WRT54GL Wireless-G router. The steps required are very similar to the WRT54G, but to avoid any confusion, I created this guide.

  • My New UPS: APC Back-UPS RS 1300VA

    My New UPS: APC Back-UPS RS 1300VA

    I have written many posts about security and archiving. Mostly I talked about backing up data, and securing a router. Today I’m going to talk about my new toy: a UPS.

    I have discussed UPSs in my post titled What is a UPS?, but in this post I will talk about the one that I recently purchased. This UPS will protect my computer, and data, from the effects of “dirty” power and power outages that can occur on a regular basis during violent storms.

    My New UPS: APC Back-UPS RS 1300VA

    UPS: Protection for Your System

    How many of you have had the experience of losing all your data when the power has gone out? Have you had your system or hard drive crash when a spike in electricity came down the power lines and into your home?

    The above two problems can be quite common to some folks, and can be really frustrating, but they are preventable. Protecting your computer and data is more than just securing your Internet connection, or making backups, it is also about shielding your computer from the elements. This is where a UPS comes in.

    A UPS is simply a box that is connected between the main power from an outlet to your computer. It contains a large battery, that when fully charged, can provide your computer with several minutes of power during a blackout so you can safely shutdown your computer normally.

    A UPS will also protect your computer from the changes in electricity coming to your home from your power company. It will provide “clean” electricity to any equipment connected to it to avoid any electrical damage to the equipment.

    Recently, I purchased the APC Back-UPS RS 1300VA to protect my desktop computer, cable modem, router, and monitor.

    The Unit

    The UPS I purchased provides 780W/1300VA of power, which is more than enough for the equipment I have connected to it. It is important to choose a UPS that can provide enough power to all the equipment you wish to connect.

    The UPS isn’t large (h: 8.74 in, w: 5.23 in, h: 14.01 in), and weighs about 30 lbs. Much of the weight is from the battery. The small size allows me to place it under the desk without taking up too much room.

    There is a red LCD on the front of the unit that displays various status information about the system, including the current load, the estimated amount of time that can be run off the battery, and the battery charge. You need to cycle through some of the information to display what you are looking for.

    All equipment is connected to the back of the UPS. There are two outlets that provide surge protection only (does not run off the battery), and six connections that provide battery backup. When the UPS is turned off, no power is provded through the battery backup connections, but the surge protection outlets continue to provide power.

    There are also other connections on the back. Two phone jack connections to provide protection to your phone/modem/fax, and protection for your cable line. A third connection, called the data port, allows you to connect the UPS to your computer so you can monitor the UPS using the provided software. I have yet to use the software, but from what I have seen elsewhere, it looks very useful.

    The UPS definitely has everything you need to protect not only your computer, but also your cable and phone line, and monitor it all from your computer. Let’s see what it is like to use.

    Easy-to-Use

    Using the UPS was really easy, and it came with a large poster-size instructions that consisted of diagrams on using the UPS. The instructions are similar to the ones you get with a printer.

    I connected the battery, which was inside the UPS but not connected, and then plugged it into the wall outlet. The instructions stated that it would take 16 hours to fully charge the battery.

    After it was charged, I turned on the system, and was happy to see the LCD light up and tell me that the the battery was fully charged. I then connected the equipment to the unit.

    I connected the monitor and computer to the battery backup outlets. I then connected the cable modem and router to another outlet (they were also connected to a power bar). My external hard drive, and external DVD writer were each connected to two other outlets, which still left one outlet unused.

    I connected my printer to the surge protector outlet because you shouldn’t connect a printer to the battery.

    That was all that was needed to use the UPS. I turned on my computer, and everything started up fine. I took a look at the UPS and noticed that of the 780W of power, my system was using 111W, which means I have more than enough room for other equipment. It also stated that when my computer was on, I would have 28 minutes of power from the battery if I suddenly lost power.

    One of the main reasons I bought the UPS was to keep my cable modem and wireless router active during a power outage. When I turned off my computer and monitor, the UPS indicated that the cable modem and router was using 11W of power. At 11W of power usage, the battery will allow me to run my cable modem, and router for 280 minutes (almost 5 hours) during a power outage. I will be testing this by unplugging the UPS to simulate a power outage to see how long I have before I run out of battery power.

    My next step is to install the software so I can monitor my UPS from my desktop. One thing I like about the software is the ability to put a computer into hibernate state during certain situations.

    My Impression

    Overall I am pleased with my APC Back-UPS RS 1300VA. It was easy to use and well documented. It provides more than enough battery backup outlets for all my equipment, and includes the two additional surge protector outlets for printers and faxes. I’ll have to try the software next to see how it works.

  • Router Settings to Secure a Wireless Network

    Two of the most popular posts on Technically Easy has to do with securing two different wireless routers: the Linksys WRT54G Wireless-G router and the D-link DI-524 Wireless router. At this time I only have those two guides available on securing wireless routers.

    For those with other wireless routers, I decided to outline some of the security settings you can enable, if available, on your wireless router to make it secure.

  • Four Months of Using Mozy

    Four Months of Using Mozy

    I have written several posts regarding backing up your data. I have mentioned many different forms of media that you can use to keep your data safe. Over the past four months I have been using an online backup solution called Mozy.

    While I have written about Mozy in the past, I will sum up my experiences thus far with using the online solution, including the pros and cons of using Mozy.

  • Is Your Data Safe?

    I have been scanning and archiving old family photos in order to help preserve them for the future. The first set of photos are the only copy of each photo available so they were chosen first for archiving.

    It is important that when you archive photos that you create a system for backing up your files so you won’t lose them. I have created my own system that should ensure I will always have a copy of each file I archive.

  • My Introduction to Online Backups

    Recently I have begun to think more about my data, and how it should be backed up. Currently I back it up to an external 250GB Western Digital hard drive, and also to multiple Taiyo Yuden DVD+R discs. One copy of the DVDs are stored offsite for disaster recovery reasons. I wanted to include another backup means in the mix.

    I went online and and began to search for various online backup solutions. There are many online companies that offer backup solutions, and each one has its good and bad points. I quickly gave two of the most popular sites a try, and this post will discuss my findings.

    Backup Requirements

    When I thought about backing up my data online, I had specific requirements that needed to be met. Some requirements came about after trying out certain solutions, and I eventually added them to the list. The requirements are listed below:

    • Must be affordable. Unfortunately, I am not made of money so I can’t spend a fortune on backing up my data. I currently have 100GB of data, and that will grow very quickly.
    • Must be able to back up from an external hard drive. This is very imporant as all of my data is on an external hard drive.
    • Must run silently in the background. If an application is to be installed, it must run quietly and efficiently in the background. It must not use a large amount of the CPU and Internet bandwidth when the machine is in use.
    • Must transfer the data securely. The data that is sent from my computer must be encrypted first, and then travel over the Internet securely.
    • Must be quick to upload and download. I have a broadband connection (10Mbps down and 640kbps up) so it must make good use of the connection to reduce the transfer time.

    The above requirements can change as I think of others, but the ones listed are a good start to what I am looking for in a service.

    Carbonite

    Carbonite was the first service I tried, and is one of the popular online backup solutions available. They are quite affordable at $49.95 for one year, or $89.95 for two years for unlimited storage. The unlimited storage is a great option for me considering the amount of data that I need to backup.

    I downloaded and installed their software without any problems. But once I installed the software, I then ran into a rather big issue for me – the software can’t backup from an external hard drive. Hoping that this wasn’t a deal breaker, I quickly did a search online to get around this problem, and did find one simple solution – mounting the external hard drive as a folder on my computer.

    For those that don’t know, when you connect an external hard drive in Windows it will automatically mount to the next available drive letter. Besides a drive letter, you can also mount the drive to a folder on your computer. When you then click on the folder you will see the contents of the external hard drive.

    When I did do this I was able to backup my data, although not very efficiently. I marked my data to be backed up by selecting a folder, and then left the computer running over night. When I checked the backup status the next morning I noticed that it didn’t back up anything. When I indicated that it should backup some folders right away it worked fine. Unfortunately, I have many folders so this is very inefficent.

    The problem could be that the folder is pointing to an external hard drive. I uninstalled the software indicating the lack of external hard drive support as the reason. If they do start supporting external hard drives, then maybe I’ll have another look at Carbonite.

    For this test, I signed up for the 30-day trial.

    Mozy

    Along with Carbonite, Mozy is the other popular choice for online back ups. Mozy is cheap at only $4.95 per month, $54.45 for one year, or $103.95 for two years for unlimited storage, which as mentioned earlier is great for me and my 100GB of data.

    When you use Mozy you need to install a piece of software that will run in the background, similar to Carbonite. Mozy’s software, however, has many more options that you can configure. I downloaded and installed the software without any problems, and began to select my data to backup. I was quite happy to see that Mozy can read and backup my external hard drive.

    I signed up for the free account which gives me 2GB of storage space for free. This allows me to test out the system indefinitely, albiet, on a very small level. I selected 1GB of my data to be backed up and began the process.

    When the backup began a little window popup window showed the current status for encrypting and preparing the data, as well as the status of the transfer. The 1GB of data was backed up in about 6 hours, which means an upload speed of roughly 46KB/s. There is some transfer room here as my max upload speed is 80KB/s.

    The one thing that I don’t like about Mozy is the fact that each computer you would like to use with the service requires you to pay more. I sent an e-mail to Mozy about changing computers, such as when you buy a new one and would like to use that for your backups. About 24 hours later I received a response stating that for a new computer, I should install the software on the new computer, where I will get an error when I run a backup. I should then send an e-mail back to Mozy where they can then send me a file to make things good again. No re-uploading of all my data, which is great.

    Overall, I didn’t have any trouble with backing up my data with Mozy as everything went smoothly.

    Summary

    I have been looking into backing up my data online. With 100GB of data, I needed a service that won’t break the bank and is easy to use. I tried two of the most popular – Carbonite and Mozy, and it appears that Mozy has been able to meet my requirements.

    As with all online services, there are people that have had good and bad experiences with both, as well as other backup services. I would be curious to know your opinion, or have another service that I can try. I have yet to purchase any but will be looking to do it in the near future.
