The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Free software firewall
Hi all,
I am helping a friend to configure a network for an educative institution.
He want to provide internet access for all the 500 students.
main access point is through a low cost router/firewall since it is a pure-client network. What he want to do is to operate some kind of firewall or web content control to avoid students to access undesired webpages.
I have seen some commercial products but them offer a renovable software for about $6000/yr for 500 clients.
Is there a free, highly reliable alternative for this, like mySQL is for databases or Apache for web servers?
Windows Operating system.
Thanks in advance,
Jaime.

Linux will demand a long learning curve. The institution works just with windows in all levels.
Thanks,
Jaime.

Naomi is an client based solution, i dont know if there is an free alternative which runs at server basis

You need SafeSquid, it's a free proxy server doing just the thing you need and lot more.

http://www.safesquid.com/

I just checked, and there was some maintenance going on, so you can download it from here also:

and here's wikipedia entry if you want to read more:

safesquid is a linux product, as I stated earlier, I am looking for a Windows product.
Thanks,
Jaime
 
04.22.2008 at 01:33AM PDT, ID: 21409021
Safesquid is avalaible for both linux and windows.

.. and heres a link to the windows download directory:

hmm, it is interesting how hard is to find Operating System requirements for SafeSquid.
Also pricing is not explicit for licenses on 200+ users, but still is an option.
I will wait for other suggestions.
 
04.22.2008 at 03:15AM PDT, ID: 21409447
I would say, that if you want to stick with windows, it will be impossible to find totally free and even decent proxy for that many users. I'm sure that if you mail squid and tell them you want to order it for school, you will get discount:

here's some other software, although i have no experience on it, and it's again only free for few users.. but schools get 30% off so version for unlimited users will cost about 200$ i guess.

I would like to add, that linux has many easy "firewall" or "proxy" distributions, some of them even work straight from CD, so you should really consider linux if you are looking for free solution. There will be not much configuration if you pick distro that is designed for this exact purpose.

Quick googling brought these, amongst many others:

http://www.sentryfirewall.com/
http://www.untangle.com/
http://www.redwall-firewall.com/
http://www.smoothwall.org/

Atleast sentry and redwall can be used straight from CD, so you can try them without any risks.  
Sad but true, words "server" and "free" have always been quite unknown to windows world. Atleast when you try to combine them with "good", "working" or "stable".
