Subject: Qualys scanner fails to detect rst.b trojan?

Hi

I recently had an infection on one of my machines with the linux rst.b trojan. 
Qualys has a more or less detailed analysis of the code, and provides a 
remote detection tool here. 
https://www.qualys.com/forms/remoteshellb.html
But even though I saw the running trojan process, knew the port of it and it 
was listening for incoming connections, Qualys' remote detection tool told me 
my host was clean. Did anyone run over the same behaviour? Is there a working 
remote detection utility?
