Installed it according to directions. Seems to be working. Not sure how long it will continue to work as the Help Menu says it requires activation and asks for a Registration Code #.

For those who want to uninstall it and can't find it, in your program list it is called: Intrusion Detection System Sax-2.0. It doesn't start with the name, so beware!

For this to perfom the functions described in the promo it needs to be installed on a windows server acting as router to the WAN (internet) that is the only way bar installing a hub and running all networked computers off that for seeing all packets arriving and leaving a network. It is of limited use on a workstation and potetially of no use if that workstation is a rootkit infected part of a botnet. Not too many non-comercial users have a windows server OS acting as router for their domestic ADSL plus it doesn't seem to supply packet contents or a way to examine a potentially rogue streams data to confirm its nature. It also wrongly diagnoses my completly functional routers UPNP notify packets as malformed, suggesting that its rules are a little too narrow in scope.

I don't think changing the voting system will change anything.

I've noticed a lot of people here click on Thumbs down and No to good comments simply because they don't like the software being given.
As the comments get higher, people vote more on No or Yes (Depending) as other folks don't go so far and hope they're say will be seen.

It's human nature to be awkward but Freedom of Speech is even better!

There are a lot of good comments today specifically been clicked *No* simply because the thumbs down voters did'nt like the software.

I ddoubt a multi-voting system would change that!

Fact is this software is only useful IF it finds all computers/connections on your network and of course can find a users wireless adaptor.

The program didn't want to work with XP SP3. After a little while I realized that it does, however, work by setting it to run in any compatibility mode (I don't know if this will have any effect on performance...).

Looks like an interesting program, hard to say more than that atm.

PS. On a really weird side note, try entering random numbers/letters into the registration key box. The message it returns is "you enter the activation of the information is incorrect, please re-enter after make sure that!". Bad grammar scares me. Especially in a program that oversees internet connections.

When you get the error "The application has failed to start because MFC71U.DLL was not found. Re-installing the application may fix this problem." It is because Windows Vista is putting the .dll file in the windows folder instead of the windows/system folder. Just copy or cut the .dll file from the windows folder and paste it into the windows/system folder. To find this file in the windows folder. Press the start button and go to "Computer". Scroll down untill you get to the "Windows" folder. In the upper right hand corner where it says "search" type "MFC71U.DLL". Right click the file, click copy. Then click on the windows folder, right click on the system/windows folder and press paste. This works I promise!!

I have no idea whether the company exploit or exhibit some user info but one thing is sure they need a better marketing plan.Because the nature of the application it is on the bleeding edge of the security and needs build much more user trust than any other type of software.

Unable to run the program as it's requesting a registration code. 77 comments with many requesting an answer to the same problem, but no responses with a solution as yet! I thought this forum was for discussion about the program itself ~ pros, cons and solutions so that everyone can benefit?

In my experience, nothing network-related works in Vista Home or Home Premium, and for the same reason.
They're useless operating systems.

I work for a software vendor and we won't even program for Home.
We've already moved on to Windows 7 and only support Vista Business, Vista Enterprise and unofficially, Vista Ultimate.

Why bring this up? Because this application ROCKS and I'd hate to see it spoiled in the process of making it work on what will soon be an orphaned operating system.

I agree that Wireshark is excellent, too, though buggy. It has enormous potential.

If you are a single computer user, you don’t need this… (from the FAQs):

What can I do through Sax2?

You are quite wrong about there being no use for this program if one has a single computer.

This is a packet sniffer. It captures and records the data streams on a network. When a single computer user connects to the "World Wide Web" his computer joins a network. His computer connects with other computers using the Internet. Note the last three letters in "InterNET. Sax2 captures all packets of information and instruction and presents the packets for interpretation.


If a person does not have the slightest knowledge of interpretation of packets a start might be an illustration of two computers (the web page shows how to determine the "address" of computers in communication with one another and a data packet. http://www.securityfocus.com/infocus/1822 .

Interesting software. Installs fine Xp Sp3, no issue or conflicts
with Avast or Comodo.

I really like the fact that it does not put any extra services running
in the background on startup. I think it's great that you can simply turn it off and exit it when you don't need it. So many of these types
of software leave bits and pieces running in the background after you
have shut it down. This does not.

Excellent tool for those wanting to see what is happening under the
hood of their network.

DO not download this product. You cannot remove it simply by uninstalling it. Also, When I closed it and tried using the program again it stated that a previous version is installed and it will restore now.

I will not download this to try the product again. And I WILL NOT be purchasing this garbage product. Wireshark works great and is still the best protocol analyzer/sniffer out there.

even without any license yet, the software works very well, providing a lot of useful information on what's going on. One feature it appears to NOT have though, but that would have been extremely useful, would have been WHOIS lookup capabilities so that you could look up information on suspicious ip addresses.

I do hope GAOTD is able to provide license before the giveaway expires, coz this is a cool prog and works well on my xp machine and worked well on the vista machine when I had it connected and was testing the program on it.

Virus total report for this showed all clean except Panda which said "suspicious file". However, Panda is the one engine in Virus Totals group of engines that is almost always giving false positives.

I had the same mfc71u.dll error, but I downloaded it & put it in \windows\system, and it works now. I noticed an odd issue; when I maximize the application, it oddly enough puts the top of the window about an inch lower than the top, and the bottom an inch lower than the bottom of the screen. So instead, I just resized the window to about full screen, since the maximize command for that program isn't working.

I guess this program could be helpful, even on single-computer networks, for those who go online, as it shows what is coming in and going out of your computer.

Software isn't activated (as others have said). This is nothing more then a 30 day trial. The price tag used with the web site shows:

Single User License 30 Day Subscription $69

So after 30 days, the software will most likely no longer function.

For those interested, a tracker was used here (as I was confused when the software still wanted an activation key) to see if the GAOTD install even used the registry or placed any files on the system to signify a registration. No action was done by the installer from GAOTD. Based on this, we only received a 30 day (licensed) version of the software, and not the normal licensed version usually provided.

Actually I think that the FREEWARE WIRESHARK can do a better job than this:

Anyway I was wondering who can use these kinds of SW apart from NETWORK and SECURITY MANAGERS.

Thanks Fubar! (comment #21) I was thinking I'd install this, but it looks like I don't need it after all, having both of the other items you mentioned installed already. In particular I don't like it running as admin and connecting to the 'net while monitoring - seems untenable for a product touted as security software. Wireshark does this without either of those requirements, or I should say the precursor, Ethereal, works that way. The advantage I see to Sax2 is it monitors continually where I don't have Ethereal loaded until I need it.

Since I'm not installing this a vote would be pretty irrelevant. Just because it doesn't fit my needs doesn't mean it's bad - or good. (grin)

Excellent offering though, GOATD! Keep up the good work!

65 Pete, I also live in Asia. I do use Chinese sites often because they provide a lot of usefull surces at little or no cost. I know very well that my activity is monitered by the government computers. I am not concerned though because I am not using the sites for any harm to anyone.
China is becoming the place to pay attention to. I enjoy going to China more than any other nation in Asia. If a person shows a little respect for them and their ways then there is no problem at all. The Chinese value education very highly and many are in the top ranks. Too many people is their real problem and they are trying to do something about that.

Yeah, I'm working on my CCNA right now. I will be DLn and passing this allong to my classmates.

If you dont understand packets and what this would be used for, go to "You Tube" and search for networking videos or security.

I'm using wireshark to track my kids browser, there are three and six.

Although I have their browser pointed at noggin and disney. everynow and then they get pop ups they should not be getting. As I detect them, I will be notifing my Internet provider and adding the source into my firewall.

I hope this program is as good or better then what I have now.

Great that you got it on here GTGO

It seems to be a good software, but looking on their website I am in doubts about the future of it. It will expiere between 3 and 12 months? Check it out if you don´t believe it. Giveaway normally gives us free software. Ok, it seems this one is free, but what will happen if the time limit is over? We need to pay for continue using it? Maybe I am wrong and it´s free forever? I don´t know. So, the reason I write all this is: Please somebody who knows more of thies program please answer my doubts. It also would be great if somebody of the companies who are giving us away thier pieces reads our comments and answer our questions. Most of us aren´t professionals and it´s very easy to download everything but later our pc´s are full of software which maybe only the half of us understand to use it. If my post get many "yes"-cicks, maybe the owners of Giveaway will read it too and working on giving us all a better service. Anyway if some worker of the software companies will show up here and help us out would be even good for them because they could sell more because of a good service. What do you think? Have a great day all of you and sorry of my English, because English isn´t my mother language.

What a great site! Most of the downloads I can't use, but a lot I wish I could! Although a lot of the reviews tend to be negative, I've found these to be from ungrateful, Iwantitnow,IwantitthewayIwantit, & Iwantitfree-type people. Posts from people who've taken the time to actually explore the programs are most helpful in deciding if I want this download. W/O these informative posts I'd have a lot of junk on my computer. Thanks GAOTD and the posters who aren't snide.

#28 said, "so no one spies on u." I ask, "What about the company that wrote this software?"

#32 said, "Looks like an interesting product, but my big concern is that the origin of this software is China…" I say, "Me too!"

The insecurity I feel towards this product up to this point is keeping me from downloading it. Will one be giving control of their computer to an unknown entity in China? I will check back later to see if anyone cares to alleviate my fears.

My concern is the one raised by #21:
"There are security issues with installing a product like Sax2. It monitors your network traffic, and it maintains an HTTP connection with an Internet site (necalli.lunarmania.com). It’s from a Chinese company, but they don’t try to hide their location or contact information."
This reminds me of Skype's recent problem where the secure chatting service was compromised by giving a backdoor to the Chinese government who had data available on a server that others could access. I work in Central Asia, and government information monitoring is better than their handling of information. I'd like to use this product, but I'd also like to know what information the program communicates to the Chinese internet site named above. Any thoughts?

I'd like to have tried this but on installing it did'nt detect my wireless adaptor and when running, I switched on my wireless laptop and connected to my network...Again the program did'nt detect any computer coming onto my network :-(

I can't really see the point of keeping this installed if it's going to detect nothing.

It would have been great if it COULD detect someone trying to connect to your wireless network.

I thought this would have been the reason to have something like this installed?

It looks like a great software for Network Admin's but very little use for "strictly private" like the agreement says. I don't see why a private person would have a large enough network to take full advantage of this software. I'm not going to give this one a try.
