We need a Whois server on a Linux Box to respond to outside queries for domain names. We currently run it in Windows but it is not very stable. The Whois server needs to get data from a MS SQL database. - We need to be able to set a limit to the number of queries per minute. - We also need to be able to black list or white list certain IP addresses. - We need to be able to show output text - easy to change or modify it.
