I use a web hosting company with a Windows / SQLServer package. The SQLServer and the webserver are on different boxes on the same subnet. The company also has Linux hosting plans, and I assume that at least some of the Linux boxes are on the same subnet.

Should I be worried that someone could run a packet sniffer and listen to port 1433 for my clear text SQLServer username and password? Is there an alternative secure port that I should use? What are my options?

I am currently connecting from my webserver to my SQLServer box via "DSNless Connection."
