			<content:encoded><![CDATA[<p>I&#8217;ve been waiting for prices to drop on the dual-band wireless routers and today the price was right for a <a href="http://www.vizio.com/xwr100.html">Vizio XWR100 Dual-Band HD Video and Wireless Internet Router</a>.  At Sams Club it was selling for US$69.98, which was less than half the price of the Cisco 3000 I had been eyeballing.  Granted the XWR100 has 4-10/100MB ports, whereas the 3000 has 10/100/1000MB ports, but then I have a separate managed Gigabit switch for my servers.  I&#8217;ll keep the old WRT54G with DD-WRT for a spare and test this Vizio unit at home for a bit.  Setup was brainless, the unit only comes with a power adapter, a 1.5&#8242; Ethernet cable, and a two page setup guide, which is mostly pictures anyway.  It has a USB 2.0 port for external storage that I have yet to test.  Time will tell how this device performs, but for the price I couldn&#8217;t leave the store without one.</p>
<p>UPDATE_20101203:  So far, so good.  The routers USB port works and presents an external hard drive as a share.  Connectivity to the connected hard drive isn&#8217;t as fast as to my server, but it would work as a central storage location for a small network.  The 5.8GHz network is being used for streaming video from my server to a couple rooms and that is also working fine, whereas before a room to room video stream was disrupted when an internet download was started.  Overall, I&#8217;m happy with this router and feel that it was a good purchase.</p>

			<content:encoded><![CDATA[<p>After fixing the gas trimmer motor last night I needed a geek fix.  So, I installed <a href="http://www.rockbox.org/" title="Rockbox - Open Source Jukebox Firmware">Rockbox</a> on an older 5th generation iPod that was laying around.  It was a painless experience with the graphical installer that took only a few minutes.  I even uninstalled the program and reverted to the Apple firmware just to be sure.  </p>
<p>The added <a href="http://www.rockbox.org/twiki/bin/view/Main/FeatureComparison" title="RockBox feature comparison with original manufacturer firmware">features </a> over the original Apple firmware are what make Rockbox shine.   Some of these features include:  support for over 15 Sound Codecs, including OGG and FLAC, themes, tagging, plugins, and a spoken inteface.  Oh, do I need to mention that it&#8217;s Open Source with constant improvement?  Rockbox has breathed some new life into my 5th generation iPod and I want to extend my thanks to the <a href="http://www.rockbox.org/mail/" title="how to contact the Rockbox crew">the Rockbox crew</a>.</p>

			<content:encoded><![CDATA[<p>After running the <a href="http://www.microsoft.com/windows/products/winfamily/windowshomeserver/default.mspx">Windows Home Server</a> (WHS) for about three weeks, I have now started testing the <a href="http://www.amahi.org/">Amahi Linux Home Server</a>.  Obviously, the WHS is very Windows centric and it&#8217;s also very easy to use.  However, the Amahi Linux Home server is different in many areas, not good or bad, just different.  I&#8217;ll need some more time to work with the Amahi project and already have some feedback for the developers.  While I have a preference for the open source projects, I also understand that some people are just going to want a Microsoft Windows solution.  And I want to be able to provide the right solution to my clients.  </p>

			<content:encoded><![CDATA[<p>The topic of safe computer practices is brought up on a regular basis with members of my family and friends network.   Almost all of them use a version of the Microsoft Windows operating system.  So, this post may seem slightly focused on one particular operating system with some of the recommendations because a majority of the computer users do use Microsoft Windows.  I will not get into the fact that there are other operating systems available and their level of security, all operating systems have vulnerabilities.  One of which is the computer user.  Some of the sites that I reference later on actually have additional information specific to Linux and Mac users.  I am broadly addressing the fact that my family and friends have computers and need to practice safe computing when on the internet.  So, back to my conversations with my family and friends.  </p>
<p>It usually starts with a comment like &#8220;my computer is running REALLY slow&#8221; or &#8220;I keep getting windows popping up on my computer&#8221;.  These comments are only two of the many that inevitably arises during a conversation.  They all know that I&#8217;m an IT professional and work with &#8220;computers&#8221; and I am disturbed some of these people are getting advice that is definitely incorrect or grossly misinterpreted.  I feel that it&#8217;s inexcusable when bad advice exposes people to computer viruses or identity theft.  So, I am using this post as an opportunity to provide information showing that my recommendations or suggestions are in line with industry best practices and are recommended by well known computer experts.</p>
<p>I am also going to provide links to web sites that anyone can visit to see what other computer experts are saying about home computer and internet security.  There are additional steps that everyone should take if you run a business out of your home or are mobile (laptop or intelligent phone), but those topics are for later discussions.</p>
<p>For starters, <a href="http://www.getsafeonline.org" title="Get Safe Online">Get Safe Online</a> has a 10 minute internet safety guide.  The 10 minutes to read the information and then a little more time to make some changes could save you hours of recovery later on; not to mention the cost of the services by the &#8220;geek team&#8221; or whatever support service you employ.  You should also consider the cost of potentially losing all of your computer data because your hard drive failed or is destroyed or <a href="http://blog.washingtonpost.com/securityfix/2006/05/ransomware_rising_1.html" title="Article online from the Washington Post">held rasom</a> by evil computer software.  </p>
<p><a href="http://www.cert.org/meet_cert/" title="About CERT">CERT</a> and their web page for &#8220;<a href="http://www.cert.org/homeusers/" title="CERT's home computer security recommendations">New and Home Users</a>&#8221;  is another great location for information related to computer security.</p>
<p>And don&#8217;t forget your internet service provider or ISP.  In my area the three major high-speed internet service providers are AT&#038;T, Comcast, and Charter Communications.  All of these companies provide free information to their customers on safe computing and internet use.  They also provide computer security software programs for free as part of their internet  service offerings (at the time of this post).  Charter offers a High-Speed Security Suite that is free with certain internet access packages and Comcast has a <a href="http://security.comcast.net/" title="Comcast computer security webpage">Comcast.net Security site</a> where they offer the McAfee Security Suite for free to all with a Comcast High-Speed Internet subscription. As Comcast promotes, it&#8217;s &#8220;No strings attached.&#8221;  <a href="http://security.comcast.net/" title="Comcast computer security webpage">Comcast&#8217;s security site</a> has some valuable information that any computer user can use.  I will take this opportunity to mention one link in particular from the Comcast.net Security page, which is the &#8220;<a href="http://security.comcast.net/get-smart/security-trends/best-practices_print.aspx" title="Print these top 10 tips to secure your computer online for reference">Top 10 ways that you can protect yourself and your computer online</a>.&#8221;  I discovered that AT&#038;T has <a href="www.corp.att.com/safety/">security information related to it&#8217;s services</a>.  And checking the features of the AT&#038;T basic DSL package revealed that they also include solutions for computer security.  Astute users will notice that these recommendations are repeated across most of the computer security web sites.  </p>
<p>There is little excuse for someone not use one of these free offers if your a customer and you can&#8217;t afford or are just unwilling to buy computer security software.  Also, I am fully aware that there are free computer security programs that I intentionally omitted from this post.  My experience is that most people will not update their computer programs by themselves, especially when it involves 3, 4, 5 or more programs.  So, I almost always recommend solutions that are easy to use, include as many of the security features as possible and have the ability to update, or check for updates, automatically.  I recommend that customers ask their ISP customer support if there is a similar offering when it&#8217;s not clearly apparent.</p>
<p>So, just like wearing your seatbelt in a car is common sense, you should develop a computer security common sense that includes the 10 most common computer security recommendations.  </p>

</a></p>
<p>The <a href="http://www.staysafeonline.info/about/index.html">National Cyber Security Alliance</a> (NCSA) has designated October 2007 as National Cyber Security Awareness Month.  I feel that information security is an ongoing process that is not limited to any single month, week, or day.  However, this is an opportunity for the cyber security savvy person to focus on educating their family and friends during National Cyber Security Awareness month 2007.  This is especially important with the <a href="http://en.wikipedia.org/wiki/Winter_holiday_season">holiday shopping season</a> approaching when many people purchase new computers, shop online, or add new gadgets to their computer network.  It&#8217;s also a time for &#8220;security&#8221; companies and organizations to hawk their own solutions.  So, get educated yourself or educate your family and friends.  And be sure to avoid any bogus security products by asking a technologically savvy friend for some advice before purchasing a computer security solution.</p>
<p>Another great resource for home computer security is the <a href="http://www.cert.org/homeusers/HomeComputerSecurity/">CERT Home Computer Security</a> web page.</p>

			<content:encoded><![CDATA[<p>The <a href="http://www.ipflow.utc.fr/index.php/Cisco_7200_Simulator">Dynamips Cisco router emulator</a> is a great tool to practice and test Cisco IOS configurations.  And part of the IOS configuration process is the security configuration.  Cisco offers a document on their website called <a href="http://www.cisco.com/warp/public/707/21.html"><em>Improving Security on Cisco Routers</em></a>.  Robert Thomas has written a &#8220;<a href="http://www.cymru.com/Documents/secure-ios-template.html">Secure IOS Template</a>&#8221; to help provide the Cisco router administrator with a place to start.  George Jones has written a tool, <a href="http://ncat.sourceforge.net">NCAT</a>, that will validate Cisco router configuration against a template to ensure that any router configuration follows the policies in the template, which allows an administrator to check many routers more quickly.  An organization can modify the default template for their particular security configuration policies, but the default template is enough to check for good practices settings for any configuration.  You can find NCAT through it&#8217;s development web page at <a href="http://ncat.sourceforge.net">ncat.sourceforge.net</a>.  <a href="http://www.cisecurity.org/">The Center for Internet Security</a> has tools to benchmark a routers security configuration and many other systems too, including Windows and Linux/Unix, Cisco PIX, and some applications.  It&#8217;s a good resource.</p>

			<content:encoded><![CDATA[<p>This <a href="http://www.duel-systemsadapters.com/">DuelAdapter</a> PCMCIA to ExpressCard adapter is not working with my HP notebook and 32-bit PCMCIA cards.  The Windows XP SP2 system event log entry is &#8220;The device &#8220;Generic CardBus Controller&#8221; has detected a CardBus card in its slot, but the firmware on this system is not configured to allow the CardBus controller to be run in CardBus mode. The operating system will currently accept only 16-bit (R2) pc-cards on this controller.&#8221; </p>
<p>Per duel-systemsadapters.com support: &#8220;<em>This is a known firmware issue with HP/Compaq notebooks. We are in the process of getting this issue resolved as soon as we can. When a solution is available you will be able to get information on it from the http://duel-systemsadapters.com/ web site.</em>&#8221;</p>
<p>I have successfully tested older 16-bit PCMCIA cards: Dell TrueMobile 1150, Orinoco Gold, Cisco 340, Linksys Ethernet. But my 32-bit cards are not recognized by the system. Time to call HP and see whats up.  Stay tuned.</p>
