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!

A question about Nmap scan results

Asked by snyperj in Linux Network Security, Miscellaneous Security, Network Management

I am having a problem connecting via odbc to a MySQL database on a remote host. The host said the problem is not on their end. I don't think the problem was on my end becuase I can connect to other MySQL databases using odbc on other hosts.

I downloaded a copy of NMap and rant it on both hosts. The problem host (HOST A) and the host where I CAN connect (HOST B). Port results are below.

Questions: I know MySQL listens on port 3306. As you can see, on Host B, 3306 is shown as OPEN where it is working fine. However 3306 does not even show on the HOST A results. DOes that mean it is definitely NOT open?

What makes a port display here or not display on this scan list. Both hosts have many ports (83 & 89) that are "Not Shown". What keeps them from being shown and if they are not shown, does that mean they are closed?

I am confused by that because on HOST A it does include some "closed" ports on their list.

Just trying to understand this... I already sent them an email that said I didn't think they had 3306 open... so I hope I didn't "jump the gun..."
