Setting Your Computer's Home Page
Whatever browser you are using, whether it be Explorer, Netscape or Opera, you can load your own home page settings. Your home page is simply the Internet site that your browser is set to go to when you start it up. Your home page may be set to www.pccompany.co.nz, or it may be set to load the Actrix page on start up. Whatever it is set to, it is easy to change, and there may be good reason to consider doing it yourself.
Is there a web site you check daily, or one that you go to often? Perhaps it would be a good idea for that to be set as your home page. There are plenty of sites that are specifically designed to function this way. One excellent New Zealand site for this purpose would be NZCity (http://home.nzcity.co.nz/). This site has fresh news articles every day as well as your horoscope, weather reports for your city, a tv guide (channels 1-4), a New Zealand search feature and web directory, lotto numbers and a whole lot more. The page can be customised so that it loads your particular desired settings: your horoscope, your city's weather and so forth. Starting the day with NZ City is a little like starting each day with your favourite newspaper.
Stuff is a similarly suitable site, though perhaps it's a little more news oriented. Another similar one would be NZoom (http://www.nzoom.com). Large Dot Com companies such as Microsoft and Netscape have customisable pages you can set as your home page, as do the major search engines such as Yahoo and Google. If you use Hotmail regularly, then perhaps setting that as your homepage would save you time each day. Maybe you run a small business and do banking on a daily basis. Setting your bank's web site as your home page might be an idea if so. Below are some links you might like to use:
The site that I use personally is the NASA picture of the day site: http://antwrp.gsfc.nasa.gov/apod/astropix.html. This site shows a different picture from outer space each day, and provides a simple explanation for it. One side value of this is that the pictures make great wallpaper, which means I can vary the appearance of my desk top regularly and with ease.
If you know how to write basic html code (see Norrie the Nerd's home page) then one idea is to make a page of your own, perhaps containing links to a variety of your favourite sites. This could be uploaded to your Actrix free home page space, and then set as your browser's home page.
To set your home page in Internet Explorer:
You're done, simple as that. Close down Explorer and open it up afresh to test whether you typed the address in correctly.
If you're using Explorer on a Macintosh try Edit/Preferences/Browser Display....
To set your home page in Netscape Navigator 4.7:
You're done, simple as that. Close down Navigator and open it up afresh to test whether you typed the address in correctly.
If you're using Navigator on a Macintosh try Edit and then Preferences. Select Navigator in the category field to the left, and enter the home page address into the home page location field.
Opera 5.01 allows you to set two types of home pages, one for the window you're currently in (temporary), and one "global home page." To set either of these home pages using Opera, simply click Navigation on the toolbar, and then click on Set Home Page.
The Actrix Services Section
Are you fully aware of the services available to Actrix customers under the Services section of our web site? If not, it might be a good idea to surf on over and have a look. Just go to our home page and click the Services link.
With Actrix Web Mail you can access whatever mail is in your mail box using the web instead of your e-mail program. It's not as efficient or handy as using and e-mail program, but it is designed to be there for you should you ever need to get to your mail from someone else's computer. You can read, delete, reply to and forward e-mail from the web mail page.
With the Online Help Desk you can send an e-mail directly to our support team requesting assistance.
With the Online Payment Form you can enter your credit card details securely to pay your Actrix invoices.
The Add a Mailbox Link takes you to a page where you can add another e-mail address to your account. It explains how many you're entitled to, how to create them on the Actrix server, and how to configure Outlook Express to be able to use them.
With View Account Details you can find out all sorts of things about your account, including your usage over the last few months, outstanding invoices, block time remaining (One Cent Per Minute Accounts) and much much more.
There are a number of other features there to such as help with Internet Content Control, and a vacation e-mail answering service. Just a hint, though, don't try the Monthly Volume Statistics link unless you are on an account type that pays for traffic rather than time. If you're unsure about this, you can assume you do not pay for traffic, so the link will be no good to you.
Cyberspace News Snippets
Americans Support E-mail Monitoring: A survey released recently finds Americans are worried about criminal activity on the Internet and willing to let law enforcement agencies intercept suspects email despite misgivings about privacy protections. The survey by the Pew Internet & American Life Project found 73 percent of those surveyed were worried about criminals using the Internet to plan and carry out crimes, with 43 percent very concerned.

"Every one of you is making its history." Mr Peterschmidt highlighted what he claims are five essentials that will define going forward with the Internet. Click the link below for more:
Microsoft Outlook to Ban Attachments:
In a desperate move to counter the influx of email viruses springing up all over the
world, Microsoft's latest version of Outlook will ban more than 30 types of files from
being sent as attachments. Is the prevention a cure? Following a spate of high-profile
email virus attacks in recent years, Microsoft's Outlook 2002. Click the link below for
The Top Ten Words Submitted to Searchnz.co.nz in Order Are: Jobs, Sex, Cars, Real Estate, Employment, Maps, Cars, New Zealand, Genealogy, Personals. I imagine this probably provides a reasonable indication of New Zealanders and their net use. I am not sure, however, how the word "Cars" managed to fill both the number 3 and number 7 slots.
Dot On Forehead To Replace Computer Mouse, Says Entrepreneur: If technowhiz Jim Richardson has his way, the Naturalpoint TrackIR will soon be found on desktops throughout the world. Here's how it works: A user affixes a disposable dot to his forehead or glasses. A device containing four LEDs and a camera is plugged into his computer. The LEDs shine an invisible beam of light off the dot. As the user moves his head, the camera and the Tracker's software cause a pointer to travel across the computer's monitor, much like a mouse does. Now on sale for $99US.
Apple's OS X: Don't Bite Yet: What does Apple know that you don't? OS X (meaning 10) is the most extensive revision of Apple's core software since the Mac made its debut in 1984. Although it went on sale on Mar. 25, Apple won't ship new Macs with OS X loaded until sometime later this year. It turns out there's a good reason for this, and Mac owners are strongly urged to hold off. Click the link below for more:
Internet Nut Changes Name to .Com: An Israeli Internet enthusiast, Tomer Krrissi, has formally changed his name to Tomer .Com out of apparent love and respect for the World Wide Web. .Com, as his friends call him, reckons his unusual moniker is something of a babe-magnet. The 25-year-old is a computer programmer and software engineer from Ramat-Gan in Israel, whose motto is, "I know I will make it." Click the link below for more:
Chinese to Launch Hack the USA Campaign: The recent political stand-off between China and the USA over the spy plane incident is not over yet. Chinese and American crackers have vowed to continue waging a cyber war, with the Chinese set to launch a "Hack the USA" campaign beginning on May Day. While the politicians try to settle the dispute diplomatically, an Internet war between the two countries is brewing. Click the link below for more:
Bill Gates No Longer Richest Man on Planet: Bill Gates is no longer the richest man on the planet. Thanks to the DoJ and the recent fall in tech stocks, poor ole Bill will have to make do with £37.5 billion. He had lead the world for three years thanks to his huge share holding in Microsoft but now new king of the castle is publicity-shy head of Wal-Mart S Robson Walton - worth a staggering £45.3 billion. The figures come courtesy of the Sunday Times Rich List, which lists the 1,000 richest folk in the UK. Aside from Bill's "downfall" though, the list makes depressing reading for some folk in IT...

Hacking 101.5 - Firewalls and Packets
by Dean Moor
I am again grateful to Dean Moor for this next article in his series on hacking and security. To many it is a fascinating topic. It really would be a good idea for those interested but new to computers or the net to read over Dean's articles in previous newsletters. -Editor
Hi Folks, well, so far we have discussed what the "Bad Guys" of the internet can do to your machine, and how they do it. How about for the next couple of months, we discuss what you can do to protect yourself.
This time I'd like to talk about firewalls. Firewalls (such as Zone Alarm, Black Ice etc) are programs you can load onto your computer to make you more secure from incoming nasties.
Before I get into the basics of a firewall, however, I must explain what packets are.
When you send information to others, your computer first takes the data you are ready to move across the Internet (such as an e-mail or web page request) and breaks it into smaller pieces, called packets. These packets are each numbered, and are stamped with information concerning who the packet is from, where it is going, and how many packets there are in total.
Then your computer sends this information to the Internet. Your computer examines each packet, finds the 'TO' address, and asks nearby computers on the Internet to see which are not busy, and if that computer can forward the packet.
When a computer responds, the packet is sent to that machine, which makes similar contact with other machines and where this process is repeated until your data reaches its destination.
It is important to note that the same computer(s) probably will not handle all of the outgoing packets. Some of the computers that 'volunteer' may actually be out of the way, depending on how busy the internet is at the time.
Therefore it is possible that many of the last packets sent will actually arrive at the destination before some of the first packets, depending on which computers handled what packets. However, the difference is often measured in milliseconds, and is not noticed.
At the receiving host computer (the one you sent your information to) the message is reassembled. The receiving host then checks that all data has arrived, and ensures that the packets are complete and undamaged, much like a warehouse would with new stock. Should any packets be missing or damaged replacement packets are requested from the sending machine. Once the packets are all accounted for, they are reassembled and processed. As seen in the demo below.

(You may want to click this a couple of times in order to follow it fully.)
Now, what does this have to do with a firewall? Simple; the firewall is generally placed in front of all other programs on you computer, between you and the Internet. All incoming packets must first pass through the firewall before they can be processed by your machine. This is where your rule-sets come into effect.
Say for example, you wish to allow all web pages from Actrix, but nowhere else. Your firewall will examine each WWW packet that approaches your computer to ensure that the sender's address in the packet header matches the one you set in your firewall rules. If the addresses match, the packet is let through, otherwise, it is rejected. The same process is followed for all packets that come in, regardless of the type or size. All must be accepted by the firewall to be processed by your machine.
The same process is followed for out bound packets (information you are sending) Each packet is examined by your firewall to ensure that the receiver's address is listed in the firewalls rule-set, and should any be denied, those packets simply will not go anywhere.
Your firewall can also block certain ports (electronic gates into and out of your computer) as well. Using the same methods as above with packet filtering, your firewall can see which port the information is leaving on, or coming into, and either allow or disallow the information, as seen in the diagram below.

Now, although the firewall appears to be all you need for the security of your computer, I urge you to reconsider. As you can see in the diagram above, a few ports are left open. This must be done to allow some traffic through, and as such, your computer, although safer, is still vulnerable to attack. Next month I will discuss further security applications that you can use to add to the features of a firewall.
Safe Browsing and Good Luck. Most of all Have Fun.
Error #1 Error: 691
By John Kontopos
691 - Access denied because username and/or password is invalid on the domain.
CAUSE - This error will occur if you use a bad user name
or password. Remember that passwords are case-sensitive; you may have a problem with
1. Verify that you have entered the correct password.
2. Check the Caps lock key to make sure it isn't accidentally on.
3. Try connecting again; if this doesn't solve the problem restart the machine and re-attempt the connection.
4. If all the above fails call the Actrix helpdesk (0800-228749).
Actrix and the ORBS
It has recently come to our attention that Actrix Networks has been included on a database of ISPs who encourage or allow Spam (unsolicited bulk-e-mailing) by allowing "open relay" on their servers. The database and related website is administrated by an organisation known as ORBS.
Despite its inclusion on the ORBS database, Actrix Networks does not allow "open relay" on its servers, and never has. Actrix does not, and never has, encouraged SPAM. Actrix Networks is taking steps to ensure its name is removed from the ORBS database.
Until Actrix's name is removed, however, a very small number of ISPs around the world might bounce e-mail that comes to them with an Actrix e-mail address. This is because if an ISP is a subscriber to ORBS, its mail servers will refuse to handle mail from any ISP that is on the ORBS database.
We apologise to customers for any inconvenience caused. Please be assured that we are seeking a speedy resolution to the situation.
Interesting Sites (Click the picture links to access the sites)
Please note: Actrix supplies links to these sites for your interest and possible use. We cannot endorse or take any responsibility for their contents.
This site examines the innovative lives of a variety of inventors. It looks at the inventions as well as at the types of innovative and therefore inspirational lives the inventors lived.
Trade Me - NZ Auction site
Trade Me gets great reviews by staff here at Actrix who have used it. Trade Me is New Zealand based, easy to use, and reasonably comprehensive in the stuff that it offers. You do have to register to participate, but this is simple to do. Good services are offered such as reliability reports on various traders.
How Stuff Works
An excellent site for the kids, or for anyone curious. There is no end to the amount of topics here, ranging from fuel gauges to missile systems, to Easter to dieting. If you've ever wanted to know how something works, and you've wanted it explained to you as simply as possible, then this is the site for you.
National Geographic for Kids
This looks like a fairly safe and worthwhile place to leave the kids, though, as Norrie recommends, you're best off taking the time to visit a site like this with them yourself. There are amazing facts, photo-tricks, challenges, videos and so forth. Bright and colourful enough to arouse and hold interest for a while.
Movies for Guys
Breaking News From Space
MonitorCamera.Com has some
fast but wacky technology that will actually take a picture of you right from your
computer monitor. It's really quite amazing and you should definitely give it a try.
Martindale's Reference Desk
Bringing It All Back Home
And so ends another newsletter. I really hope you found it enjoyable or useful.
Each month, content is always a struggle; not because there isn't a wealth of stuff to write about, but because of the wide range of reader interests and knowledge. I try to include material that is simple and basic as well as stuff that is a little more advanced. Striking a balance is not always easy. So, if you have suggestions, or if there is something that intrigues you, let me know and I'll see what I can find out or commission in the way of information. I have always been grateful for this sort of feedback, even from the grumpy ones who think the newsletter is way too hard or way too lightweight.
Regardless, your feedback is always welcome.
