Hardware Firewall

The best firewall is a hardware firewall that is completely separate from your operating system. It need not be a dedicated router, could be an old pentium box running Linux. Below I have found some sites that have How To's on setting up an outside hardware router using an old computer and using a little linux program that fits on a single floppy disk.

Brief Description:
floppyfw is a router with the advanced firewall-capabilities in Linux that fits on one single floppy disc.

Features:
Access lists, IP-masquerading (Network Address Translation), connection tracked packet filtering and (quite) advanced routing. Package for traffic shaping is also available.
Requires only a 386sx or better with two network interface cards, a 1.44MB floppy drive and 12MByte of RAM ( for less than 12M and no FPU, use the 1.0 series, which will stay maintained. )
Very simple packaging system. Is used for editors, PPP, VPN, traffic shaping and whatever comes up. (now this is looking even more like LRP (may it rest in peace) but floppyfw is not a fork.)
Logging through klogd/syslogd, both local and remote.
Serial support for console over serial port.
DHCP server and DNS cache for internal networks.

Sentry Firewall CD-ROM is a Linux-based bootable CDROM suitable for use as an inexpensive and easy to maintain firewall, server, or IDS(Intrusion Detection System) Node. The system is designed to be immediately configurable for a variety of different operating environments via a configuration file located on a floppy disk, a local hard drive, and/or a network via HTTP(S), FTP, SFTP, or SCP.

The Sentry Firewall CD is a complete Linux system that runs off of an initial ramdisk, much like a floppy-based system, and a CD. The default kernel is a current 2.4.x series kernel with various Netfilter patches applied. An OpenWall-patched current 2.2.x kernel is also available on the CD.

Booting from the CDROM is a fairly familiar process. The BIOS execs the bootloader(Syslinux) - which then displays a bootprompt and loads the kernel and ramdisk into memory. Once the kernel is running, the ramdisk is then mounted as root(/). At this point our configuration scripts are run(written in perl) that configure the rest of the system. It is the job of these configure scripts to put the various startup and system files into the proper location using either what is declared in the configuration file(sentry.conf) or the system defaults located in the /etc/default directory.

Most of the critical files used at boot time can be replaced with your own copy when declared in the configuration file. This is essentially how we allow the user to configure the system using his/her own configuration and init files.

All of the binaries, files, scripts, etc, used to create the CD-ROM are also available on the CD-ROM. So, with a little practice, you can easily build and customize your own bootable Sentry Firewall CD. Please see the HOWTO for more details.

Hard drive gone bad

Hard drive gone bad

The most common problems originate
from corruption of the master boot record, FAT, or directory.
Those are soft problems which can usually be taken care of
with a combination of tools like Fdisk /mbr to refresh the
master boot record followed by a reboot and Norton disk doctor
or Spinneret.

The most common hardware problems are a bad controller, a bad
drive motor, or a bad head mechanism.

1. Can the BIOS see and identify the hard drive correctly? If
it can't, then the hard drives onboard controller is bad.

2. Does the drive spin and maintain a constant velocity? If it
does, that's good news. The motor is functioning.

3. If the drive surges and dies, the most likely cause is a
bad controller (assuming the drive is cool). A gate allowing
the current to drive the motor may not be staying open. The
drive needs a new controller.

4. Do you hear a lot of head clatter when the machine is
turned on and initialized (but before the system attempts to
access the hard drive). Head clatter would indicate that the
spindle bearings are sloppy or worn badly. Maybe even lose and
flopping around inside.

5. There is always the possibility that the controller you are
using in the machine has gone south.

1. If the drive spins, try booting to the A> prompt, run Fdisk
and check to see if Fdisk can see a partition on the hard
drive. If Fdisk can see the partition, that means that it can
access the drive and that the controller electronics are
functioning correctly. If there is no head clatter, it may be
just a matter of disk corruption which commonly occurs when a
surge hits you machine and overwhelms the power supply voltage
regulator. It commonly over whelms the system electronics
allowing an EM pulse to wipe out the master boot record, file
allocations table, and primary directory. Fdisk can fix the
master boot record and Norton Disk Doctor can restore the FAT
and Directory from the secondaries.
2. The drive spins but Fdisk can't see it. Try the drive in
another system and repeat the test to confirm that Fdisk can't
read through the drives onboard controller. If it sees it in
another system, then your machines hard drive interface is
bad. You can try an upgraded or replacement controller card
like a Promise or CMD Technologies (there are others) in you
machine after disabling the integrated controller in the BIOS,
but if the integrated controller went south, it may just be
symptomatic of further failures and you'd be wise to replace
the motherboard. Trying the drive in another machine also
eliminates the variable that your machines 12 volt power
output being bad

3. If you get head clatter but a constant velocity on the
drive motor (no surging), you might try sticking the hard
drive in the freezer for about 12 hours. This is an old trick
from back in the days of the MFM/ESDI driver era. This can
cause the drive components to shrink enough to make the track
marker align with the tracks. We don't see that kind of
platter spindle wear much anymore, but back in the old days,
the balancing and bearings weren't as good. Still, under the
right circumstances, it might help. It would depend on how old
the drive is and how many hours of wear have occurred. You
have to be quick to get your info off the drive when it works.
Back then, the drives were much smaller, so there wasn't so
much to copy. So, go after the important data first.

4. The drive doesn't spin. Either the onboard controller is
bad or the motor is bad (assuming you did try the drive in
another machine). It's time to hit the net and local
independent shops to see if you can locate another drive of
the same make and model that's good. Since the drive is
probably an older drive and no longer in distribution, your
best bet is to find an identical used drive. If you know
someone with the same make and model, you might be wise to try
and persuade them to sell you their drive with an offer of
providing them with a free upgraded drive. If you can locate
an identical drive, start with the controller replacement ...
this is the simplest and least invasive. If swapping the
controller doesn't produce the desire result, you can tear
into the drive and swap the motors. While you have both drive
opened up to accomplish this, scrutinize the platters, heads
and armatures. You might even hook the drive up and power it
from a system with both drives attached. This way, you could
see anything that deviates between the actions of both drives
when they are initialized. Swapping patters is unlikely to
produce any positive result. They are a balanced system like
the tires on your car and I suspect that the balance will be
different for each drive as will other variables.

5. There's always Ontrack Corp. who will attempt to recoup
your info starting at $500 and going up from there. They don't
fix and return the drive either.

If the info is all that important to you, I would seek some
professional and experience technician in your locality who
makes his living from servicing and building computer systems
... not just selling them. If you have had much experience
salvaging information from bad hard drives, your likelihood of
success is low. In the case of soft corruption, all utilities
have their eccentricities. Often times, Norton Disk Doctor
will go too far (if you let it). It's wise to just let those
utilities small steps and then have a look at the drive and
see if you can copy it off. Norton will go so far as to rename
directories and files, and even delete them or break them up
into fragments which are useless.

Guide For Getting Free Stuff

Guide For Getting Free Stuff

Ok, if you are like me you have heard so much about the FreeIpods and FreeFlatScreens websites on different forums, blogs, IM's, etc, you are about to puke. So am I. But yet the draw of getting an Ipod for doing basically nothing is pretty strong. I dismissed all the "stories" of people getting their ipods as the marketing machine at work. However, when Kevin Rose published that not only did he receive his, but a few of his friends did as well, I figured I might take a chance and give it a go. Today I received proof that it does indeed work. Yep, I got my iPod.

Whats in it for them?
Step 1. Collect Names.
Step 2. Send those names items worth $200 or more
Step 3. ?????
Step 4. Profit

Before I signed up, I wanted to get to the bottom of the ?????. I didn't want any sweaty, filth pushing webmonkeys to have all my info, so I did my research. Gratis Internet, the parent company of the FreeIpods, FreeFlatscreens, etc. sites, recently did an interview with Wired Magazine.
In this article Gratis states that they are acting as Head Hunters for companies (more on that later) and are paid between $50-$90 per referral. Although this seems like a lot of money, this is nothing compared to what these companies spend for print advertising which does not guarentee ANY customers. So now we know what ?????? equals. ??????=$50-$90 for Gratis per guranteed customer (referral sites).

How Does it Work?
You sign-up on one (or more) of the following websites:

http://www.FreeMiniMacs.com/?r=14098976
This site gives away free Mini Macs. At the time of this writing only the 80gb MiniMac was available.

http://www.FreeDesktopPC.com/?r=13082204
This site gives away free flat screen monitors and TVs. At the time of this writing the following flat screens were available: Sony 19" LCD, Samsung 15" SyncMaster 510MP LCD TV, Samsung SyncMaster 710N LCD Monitor, Sony 27" FD Trinitron WEGA TV, or a 24" Toshiba TV/VCR/DVD combo

http://www.FreeGamingSystems.com/?r=12660654
This site gives away gaming systems. At the time of this writing the Slim PS2, Xbox, Nintendo Gamecube, and Nintendo DS were available.

http://www.FreeHandbags.com/?r=13950244
This site gives away high-end handbags. Might be a good surprise for your wife or girlfriend. =) At the time of this writing the following bags were available: Prada Mini-Hobo (black, Pink, Powder Blue), Burberry Novacheck Minisling, Coach Signature Demi Pouch (black, camel, purple), Kate Spade Pia Pochette (Black, Pink, Red)

http://www.mp3players4free.com/default.aspx?r=82419
This site gives out free mp3 players. You can get paypal $275, ipod, rio carbon, iriver, ipod mini.

http://www.dvrs4free.com/default.aspx?r=90581
This site gives away TiVo, Replay TV, and $275 paypal.

http://www.macminis4free.com/default.aspx?r=181183
Another mini mac site.

http://www.cameras4free.com/default.aspx?r=90773
This site is giving away high end digital cameras. At the the time of writing this, you follow cams are available: Canon Powershot S1 IS, Sony DSC-P100, Sony DSC-W1, Canon Powershot A95, $325 paypal.


Ok, so here is the tricky part. Once you sign up with one of these websites, you have to complete an "offer" from gratis's advertisers. There are numberous offers, some being better than others. Now remember the ???? = $50 - $90 equation? In order for you to receive your ipod/Flatscreen/Desktop PC/Handbag you have to refer 5, 8, or 10 of your friends, and they have to complete one of the offers as well. Then in order for them to receive theirs they need to refer others, and so on. So lets just look at why they are going to send an Ipod to you. (1(you) + 5(your friends)) x $90 = $540 - $250(ipod) = $290 profit for them just for you signing up. The advertisers are more than willing to pay, and FreeIpods is more than happy to send you your ipod. Works out for everyone.

What is the basic "lingo"?
"ref"/"referral" = The thing required to get your free items. These are your friends.
"green" = Status indicator that means your offer has been completed.
"yellow" = Status indicator that means your offer has yet to be completed or is in the process/pending.
"hold" = Means your account has been suspended or stopped. DON'T CHEAT.
"STV" = Means your product has been "Shipped To Vendor" You should recieve it in about 10 days time.

What process should you use to sign up (to ensure that you will get your item)
When signing up, it is recommended that you use Internet Explorer (sucks) some people have reported problems using other browsers (ex. Firefox, opera, etc.) Also make sure you have cookies accepted.

1. Click on one of the links above and enter a VALID US mailing address.

2. Complete the marketing survey - not your answers do not have any impact on you receiving your item. Just say no to them.

3. Once you have signed up, you should receive a verification email. If you did not receive one, go to the "My Account" page and click the link to have them resend it. If you still did not get it check your spam folder.

4. Sign-up with one of their partners and complete the offer. (see the section which offer should I choose) It can take up to 15 days for your offer to show completed. (A term that we freebie goers use for a "completed offer" is called "credit.") But usually they show completed after 24 hours. Be patient. If it doesn't show up as completed, you can email the site with proof and confirmation for signing up and they will give you credit.


Which offer should I choose?
Just so you know all offers require a credit card, **HOWEVER** not all of them cost anything! =) Here is a list of my recommended offers and I have not had any problems whatsover with doing these.

* Video Professor: This requires a credit card and pay only $3 shipping for computer tutorial CDs. After you receive the CDs, just call customer support and cancel your membership. Return to sender the CDs and they will refund you the shipping costs.

* Complete Home: Instant verification. Sign up for their program for $1 two month trial. You get a FREE $20 Lowes Gift Card just for doing this offer. Cancel your subscription within the 2 month trial and pay NOTHING and keep the gift card!

* Buyer's Advantage: Instant verification. Sign up for their program for $1 two month trial. You get a FREE $20 Circuit City Gift Card just for doing this offer. Cancel your subscription within the 2 month trial and pay NOTHING and keep the gift card!

* Great Fun: Instant verification. Sign up for their program for $1 two month trial. You get a FREE Walkie Talkie just for doing this offer. Cancel your subscription within the 2 month trial and pay NOTHING and keep the gift card!

* Traveler's Advantage: Instant verification. Sign up for their program for $1 two month trial. You get a FREE Thin Digital Camera just for doing this offer. Cancel your subscription within the 2 month trial and pay NOTHING and keep the gift card!

* eFax Plus: Sign up for their fax service. You get a 30 day free trial. Upon receiving credit for doing the offer, simply cancel the service within the free trial and pay nothing! It usually take 1-3 days to receive credit for this offer.

* Blockbuster Online: Try a two week trial of Blockbuster's Netflix-like service. Cancel online within trial time and pay nothing.

*Zooba: If you are a book fan, sign up for this offer. You get a book for $10 with free shipping. Instant verification.

*Various Credit Card offers: Apply for a credit card and get approved. When it arrives, cut it up and toss it out. Nothing to cancel, nothing to pay, and free stuff to gain!

Many of these offers are big companies, so you do not have to question the legitimacy for signing up under them. In other words, you will be safe because you are giving your credit card information to aol, blockbuster, and general motors, and i highly doubt that they will sell this info.

These are free, as long as you cancel within the trial period. Some offer online cancellations while others require calling their support number. Just tell them that you dont find yourself using their services enough so you want to cancel and they'll cancel your membership without any problems.

Cheating
Many of these free sites take cheating very seriously. If you want your free gift and not have you account suspended, simply DON'T CHEAT! Don't refer yourself and do all the offers yourself. If you think you can cheat the system because you are a 1337 h4x0r and you can use proxies and IP spoofs to refer yourself, DON'T DO IT. When you are in the approval stage, they will intensely throughly examine your account and make sure that all your referrels are legit and unique. Trust me, I know many people who have gotten suspended for attempting to cheat.

Multiple Accounts
This goes under cheating. It is wise not to create multiple accounts under the same site because it is against the free site's TOS. They suspend you no matter what your reason is, even if it was an accident. This also includes referring family members. You can only create one account under one household, under one IP address per site. So you cannot refer mother, sister, or brother to do it unless they live in another household.

So you've ran out of offers to do. What do I do?
Ok, if you are a freebie freak, you will probably eventually run out of offers to do because of the fact that you signed up for so many free sites did all the easy free offers. What shoud you do? Remember that free sites give you credit for a unique signup for the offers. So if you signed up for blockbuster online offer at freeflatscreens, you cannot do it again for another free site such as freedesktoppc. But there is a trick to this. A unique signup = a unique credit card that you used to sign up. So if you have a another credit card, you can sign up for the offer again. Another method is to purchase a visa gift card from your mall, or go to www.webcertificate.com and purchase a virtual debit/credit card and do the offers with those.

If you followed all these steps correctly, your free gift will be delivered to your doorstep in no time.

Here are the steps:
1. Getting friends to sign up under you
2. Approval Stage: They will analyze your account for fraud. Takes 1 week.
3. Pending Stage: Your account have been approved. You are now processing. This will take 1-2 weeks.
4. STV: Sent to Vendor. Your product will arrive in 10 days.
5. Shipped: Congrats!

Most of these freebie sites are for U.S residents only.
