Re: banner grabbing

It's quite logical that you have to place the $sock->print() outside of the while loop for two reasons:

First you do the request, THEN you get an answer
<$sock> will not have anything before you do the print on $socj so the while (<$sock>) will exit immediately if you did not do the print before it.

Hi Jaap It's quite logical that you have to place the $sock->print() outside of the while loop If you try this, I think you'll see that banners will not be returned for ports 21 or 22. This was the basis for my original question, e.g. why I'm seeing different behavior on a port by port basis based on where I place the $sock->print() statement. Thanks for the feedback though. cheers, -semio	[reply]
