IP Haiku

Every computer on the Internet is assigned its own, unique identification number. These numbers are referred to as your Internet Protocol (IP) address. They are important because they allow computers to locate and recognize each other. IP addresses are made up of four number sets, between zero and 255, and are separated by periods.

Six dot one dot one

One dot zero zero five,

Hi, y’all FBI!

The inspiration for this haiku was a similar poem written for a contest sponsored by Think Geek.

Peace, Doc

Mozilla Firefox 3, Final Release: Download Day.

The new Firefox 3 web browser is to be released on the official Mozilla Download Day, Tuesday, June 17, 2008. An informative article about this release and Microsoft’s rapid effort to catch-up using IE-8 was recently published by PC World. I strongly suggest that you download Firefox 3 directly from a Mozilla site. As I write, this site is still devoted to the download of Firefox 2.0.0.14, however.

The good people on the Firefox 3 project are trying to set a Guinness World Record for downloading software in a single day. My best guess is that they will achieve this, because there is currently no such record in existence.

More importantly, I recently tried to download Release Candidate 3 of Firefox from other sites, and while beginning to install, they displayed instructions in a language which I did not recognize. These were reputable sites, but something was clearly going awry.


While you are downloading this excellent browser, I would also suggest looking over more of
Mozilla’s software and other offerings.

A Field Guide to Foxfire 3 by Debra Lyn Richardson is available at her
WordPress site and should definitely be referred to for many technical details, feature descriptions, and links.

Air Force Aims For Full Control Of Any And All Computers

Initially, this post was written for a different audience, but I believe it is something that should be of interest to mental health professionals. Although I have a love for computers, I also have a great distrust that anything transmitted from them is secure or private. We need to think of HIPAA requirements, electronic billing, chats with clients online or on the telephone, the elecronic medical record, and so on. Everything on the internet is forever, stored in memory somewhere, and accessible from more and more sources, legal or not A post on this topic geared specifically to the purpose of this blog will be done soon.


Does that read too much like a scare headline from the Far Left? It isn't. Wired News online reports that the US Air Force itself has made it. In an April 13, 2008 article by Noah Schachtman, it is stated that:

The Air Force wants a suite of hacker tools, to give it "access" to -- and "full control" of -- any kind of computer there is. And once the info warriors are in, the Air Force wants them to keep tabs on their "adversaries' information infrastructure completely undetected."

The US Air Force Cyber Command is already being developed. Its website has many articles, pictures, FAQ's, and a countdown timer to "phase one stand up" on October 1, 2008.

I have included links to both the Wired article and to the Air Force website to allow readers to judge for themselves where we are headed. Most of my regular readers know that I border on the paranoid in my responses to be watched by recording cameras at stoplights, at toll road transponder lanes, and on our streets and intersections. I strongly object to being listened to, phone tapped, having my mail read, or just generally being observed in any manner unless someone has reason to believe I am committing a crime or am planning one.

On the other side of this topic, I want my government to protect me - from criminals, from street muggers to multi-national corporate muggers, from enemies foreign and domestic, to preserve our constitution, and defend our land. I appreciate the brave people in the military services and in the public sectors who serve us and take care of us so well and who we too often take for granted.

At a deeply frightened level, I know that a current "World War III" would be fought like no other. China has demonstrated to us their ability to blind and disorient our spy and navigation satellites by shooting down one of their own. In turn, our "accidental" transport of six W80-1 variable yield live nuclear warheads From Minot AFB in ND to Barksdale AFB in LA was given much more publicity than I would expect any military organization to allow the media. I do not see these incidents as unique, or even highly significant in the bigger picture, of which the public sees only tiny fragments through a glass, darkly. If an enemy had unfettered access to any of the Internets or grids that control our distribution of electricity, natural gas, vehicle fuel, traffic and transportation flow, food and water distribution, public and military communications, financial tractions (commercial, investment, and banking,) ... well, you get the picture. Our nation would be brought to its knees in a grinding, chaotic halt. In a much more localized manner, the electromagnetic pulse (EMP) of a conventional atomic weapon or an "E-Bomb" destroys MOSFETs, FETs, transistors, and the like if not Faraday shielded, thus disabling electronic devices in the area of the explosion. The government and Military knows this in infinitely greater detail than do I.

On a personal, much less significant level, I have been affected wrongly by the same type of capabilities as are needed to defend our nation. I sold a car to a friend who ran through four "I-Pass" toll stops without paying. I received a ticket for four infractions, complete with a very clear picture of the back of the car with my plates still on it, and a statement that not being the driver was no excuse for not paying the tickets. In another incident, Medicare gave the Veterans Health Administration all of my personal and business information (including SSN, EIN, bank routing numbers, addresses, etc.) without any notification to me. I found this out when the VHA notified me that a portable hard drive with this information on it was missing. At least they had the decency to notify me and provide for one year of credit fraud alerts. I have no doubt that, despite the precautions I take personally, this type of information has been lost, discarded, or stolen far more times than I am aware. As a simple example of the laxity of transactions in the area of credit, I have written "Require Photo ID" on all my cards, along with my signature. It has been checked only once in approximately 10 years.

So what do we do and where do we go with this sort of information? I honestly do not know. The same technology that protects us can destroy us. The same types of devices that allow surveillance of criminals, terrorists, and enemy actions are easily able to be turned on a country's own law abiding citizens. It is, after all, so very much easier to listen in on our own cell phone conversations and take pictures of our own license plates than it is to definitely identify what is happening in an enemy's hardened military site or know if a satellite is armed and has military capabilities.

*sigh*

Firefox Is Back And I'm Gonna Have A Party!

Some things make me quite cranky and obsessive, indeed. One of those things happened on Monday. Somehow, I lost Firefox. The browser would load and display itself but would not connect to the Internet. Sometimes, like its owner, this computer becomes a little unstable and ... just does unexpected things. I would say I had no idea what caused this malfunction, but I really had about 20.

The first idea on my list was that Comcast might have done something "funny." Its toolbar will only install on IE7, so that's where I started. I switched to IE7 and was again in contact with the world, albeit at what seemed like a snail's pace. OK. I knew the computer could access the web sometimes. My next thought was that I had installed and removed several minor programs, any of which could conceivably have caused a problem. I also had done both a disk defrag and a registry defrag with software which came from a very reputable company, but I had no idea where the little 1's and 0's might have been placed. I did a sys restore to no effect other than moving a few icons on the desktop. I deleted several apps to DOD standards (seven overwrites of the data), but the problem remained. I ran every security program I have (at least 10) from rootkit searches to anti-virus scans to ad removers and spyware scans. I found nothing that I didn't already know was present. Even the low risk items were then quarantined or deleted, however. Still no Firefox.

At that point I decided to be tricky and try something different. I disconnected the cable service and plugged into dial-up. Everything else worked, but still no Firefox. Drat! There went my theories about the cable provider changing something. Somewhere during all this poking of keys and rebooting, I fell asleep. That was just as well, because I probably would have just continued to poke at things until I killed the computer. When I awoke, somewhat refreshed but crabby from a dream I had (which will be my next post,) I went back to work on the problem. I was at the point of downloading Opera or Safari to see if they would work, but I didn't want to do anything traumatic to the HP.

Trying to find Firefox help while using IE7 didn't work so well, and using what help Firefox could provide without being connected to the net was relative useless. It explained clearly what the acronym "URL" stood for and explained what the proxy - client relationship is. That is when I began semi-randomly poking keys and header tools. It is also when I solved the problem. I truly hate to admit how simple the solution was, once I stumbled upon it. It seemed reasonable to use the Firefox "tools" that were available. When I got down the list of options to "options," a screen opened with many, well ... options. I made my way through them until I hit upon "advanced options, network, connection." I proceeded to take the ultimate risk and poked "advanced network connection settings." Nothing blew up and I was given four choices. Although I felt that I was tempting fate to switch from the current setting to "Auto-detect proxy settings for this network," I did it. Firefox came online immediately.

I still have no idea what caused the problem to begin with, but I was absolutely thrilled to have solved the problem all by myself. This elation lasted just long enough for me to figure out that anyone who actually knew what they were doing would likely have tried this as a first or second choice in resolving the situation. I believe it was then that I uncovered another of those inconvenient, but basic truths of life. It is extremely difficult to feel elated and incompetent at the same time.

Firefox 3, beta 4 is available for free download, but I'm not quite recovered enough from this trauma to install it yet. Another portable version of Firefox 3, beta 4 is available as a free download with the feature of being able to install it on your USB thumb drive and test it without affecting the operation of your current version of Firefox 2, whatever version. That isn't my usual quote, but is likely to prove much more valuable to those who are interested. I might actually attempt that, as it has been downloaded and the installation icon is just sitting there on the desktop mocking me.

Da Shredder Do Good

Sorry. That's a joke that only a few of my older readers will catch. Many years ago when "easy-open" beer bottles were not at all easy to open, one bottling company produced an advertisement making fun of that fact. It starred a "professional" wrestler opening a beer. When, after a great deal of grunting and sounds of great efforts being made, it was opened, he stated, "The Crusher do good!"

That does have a connection to today's topic, deleting and/or erasing files from one's computer drive. There are various degrees of deletion and erasure. The least secure is simply deleting a file by sending it to the Windows Recycle Bin and clicking on "Empty Recycle Bin." This action only erases the address (a few bits) of the file on the drive such that the computer no longer recognizes it as being present. The body of it remains. It can easily be found by someone with a little knowledge of computers and a program to view what is on the entire drive.

At the extreme opposite end of the security spectrum would be having a bit of thermite or a huge degausser installed in the computer set to destroy the entire hard drive if certain conditions are met. This method would be for serious hackers, intelligence agencies, those with child porn on their machines, or any of you who really don't want your high school nickname known, and are willing to have a lump of smoldering plastic and metal on your desk to prevent it.

In many cases, simply deleting a file is enough. If you don't care that there are retrievable remains of all your blog posts, emails to Aunt Edna, or grocery lists, fine. More sensitive information deserves more care, at least encryption and more complete deletion when you are done with it. At one time in the past, simple deletion was enough because people who wanted your data were not so common and ways to get it were not so sophisticated. Unfortunately, that has not been true for several years, so it is largely up to you to protect it.

A recent article by Linda Martin-Peoples on MakeUseOf.com reviews or mentions in the comments section, various free file, folder, and disk deletion programs. FileShredder seems to be a very useful free program. Another program mentioned in the article is a trial of a commercial program, not true freeware, and is not listed here. Data Shredder is available free from CBL Data Recovery Technology, LLC, a Canadian data recovery company. I highly recommend that you read the article on this link to their site which explains, in understandable terms, what the different levels and types of data destruction involve. There are many free file shredders available at various sites around the web. I use Eraser, parts of Crap Cleaner (which is again available at the linked site without the other software recently bundled with it,) and "other methods." There are some programs I have not listed because they are completely destructive of all data on a disk, and I don't believe any of my readers would need such an ability. If you are going to donate a computer to charity or dispose of one, contact me and I will send you the names and URLs.

Other caveats apply to this type of application. Be certain that you trust the source of any freeware you download. Open source sites with GNU licenses (like sourceforge.com, etc.,) large companies giving away a freebie to get you to buy other of their commercial software, and corporations giving away updates, add-ons, templates, etc., to their own commercial software are most often safe. The other "It seems too good to be true" sites frequently prove that old maxim to be true. The second caveat, specifically about file deletion software, is to know what you are doing! If you do, go ahead. If you have any doubt, don't do it. Ask someone first. When the files are gone, they really are gone unless you are willing to take the chance that a data retrieval company, charging $600 to $1000, might be able to get it back.

This article is presented for general educational purposes only, and does not constitute a recommendation or bad review of any particular company or bit of software. It is not all inclusive, and there are many other good and bad programs out there.

Peace, Doc

Eureka! A Server Mystery Has Been Solved!

Have you ever had a small mystery that nagged at you over time. The event only occurs in one circumstance, but you couldn't quite put the pieces together to get that "Aha!" finality? It is the kind of recurring puzzle that is of no real consequence to anyone, but it bugs the bejesus out of you that you can't find the answer. I am relatively certain that I am the only person on earth who would choose to be bothered by this particular mystery, but I did. In all likelihood it was not "solved" sooner because only a few other people in the world would have cared and they already knew the "answer." They made the puzzle. To an obsessive and inquisitive shrink, however, this became a "thing!"

I host a website with what used to be known as Microsoft's bCentral. At one point last March I had nothing better to blog about so I simply listed the names of the mail servers then in use for the email accounts on the site. I assumed that they had to be given some designation so that the rest of the network would recognize them, but the names were seemingly random and were probably assigned by whatever IT person installed and maintained them. I noted what they were, but gave no real thought to a pattern being there, as the names appeared whimsical and individual. They were:

freddie
io
monty
nudel
onyx
sparky
squeaky
sylvia

Since Microsoft outsourced its web hosting services to Concentric however, the names changed and became much more numerous. The more I saw, the harder I tried to find a pattern to their names. Some sounded like defenders of the realm, some seemed almost loving, some had an attitude, some seemed threatening, and I couldn't even pronounce one. Different subsets and arrangements were tried until one server name that I had not encountered before appeared. Click!! The names are listed below, along with a link to a list of which they are a subset:

adamant
albion
ardent
audacious
brilliant
dauntless
defiance
desperate
diligence
excellent
exertion
fervent
formidable
fortitude
hood
impregnable
indefatigable
indignant
inflexible
insolent
intrepid
invincible
iphigenia
irresistible
isis
nimble
resolution
retribution
safeguard
sentinel
strenuous
superb
tremendous
triumph
unicorn
vigilant
zealous

If you found the "giveaway" name, the derivation of the names won't come as too much of a surprise. If you didn't, it may. Give it a moment's thought before you click this link. I have to pull you into my obsession for at least a few seconds. There were four discrepancies from the list at that link, all of which I finally verified despite a slight difference in the spelling of one name, the fact that two were simply missing on that link, and that "safeguard" was included as something of a technicality.

*sigh*

I can find some of the most irrelevant things in the world to become enthralled with when I'm avoiding moving a huge bookcase. 'Twas a turrible fight, but the dreaded bookcase has now been moved.

NanoScan and TotalScan

There are a few good, free, web based applications out there amidst all the crapware. I used Panda Software's computer-based anti-virus program for a year some while back and found it to be satisfactory. Not perfect, but good. That was at a time when many of the viruses, trojans, and worms were coming from the area of the world in which Panda Software is located. My assumption at the time was that they would therefore be the first AV company to encounter many of the new threats "in the wild" and the first to develop new countermeasures. It seemed to be a good assumption. The only drawbacks I encountered at that time were a somewhat unappealing user interface and a very aggressive advertising program. Panda was one of the "other good commercial AV programs" to which I referred in a previous post on free AV protection.

When I evaluate a program for my own use I quickly head in the opposite direction from AV and other security programs that immediately do a scan, find 1,284 possible infections on my computer, and warn me of the grave consequences of not purchasing their software or services immediately. When I found and tried Panda's
nanoscan online scan it quickly had a look at my computer after I allowed it to install an ActiveX application. It reported that it found no viruses and that my other security programs were up to date. Hmm. Could it be true?

After one has scanned their computer with nanoscan, a pitch is made for totalscan. It is stated that this version can be used in either “brief” (about five minutes) or “full” (about an hour) modes. One has to sign up with an email address and a password for the free totalscan. I did so and allowed another ActiveX to run. This action started the download of a short program that literally took almost three hours to complete on a dial-up Internet connection. When this process was completed, totalscan found 10 cookies that I knew were present and showed a large red button labeled "disinfect." I hopefully pressed it. The next screen informed me that I must be a member of totalscanPRO for anything to actually happen. Technically, Panda delivered exactly what was promised, a scan. I am so freaking gullible that I must be a relative of Wily Coyote.

The purchase page even insisted that I was from the UK and wanted payment in pounds. I'm afraid I cannot recommend nanoscam, totalscam, or totalscamPRO. Some might want to take a look at Panda's
relatively non-technical descriptions of crimeware, hoaxes, rootkits, and the like. Otherwise, it did nothing that the previously listed freeware did not do except leave me with junk to clean out of the computer and two or three hours of subvocal swearing which I must attend to. Despite my current displeasure, I would still state that Panda's programs and services are probably in the class of "other satisfactory commercial security software." I'm glad I used a throwaway e-mail address, though.
