Question : Interbase Server 7.5

Hi All,

I just started this new job and have been asked to rebuild a Interbase server 7.5 edition onto a new box. I have never seen Interbase.

Is this a free software? Where do I download it from? I have looked at some http sites and they are all broken links.

Is there an instruction manual that explains how to build and configure an interbase server?

Answer : Interbase Server 7.5

I see this question has gone into "neglected status."

The correct answer is still the CAPTCHA image, but you might be able to get away with a form token. It should prove more reliable than the IP address, but less reliable than CAPTCHA. Here is my teaching example of how to use a form token.

Best of luck with it, ~Ray
