DC++ - Connecting to a known Hub not possible

Hey,
I have been trying out our DC++ support today for the first time. The problem is the Hub I'd like to connect to is not listed within a DC++ Hub list file, but I know only its IP (it's a Hub in a private intranet filesharing network at my universiy). However if I use the connect to dialog, a chat connection is opened to the Hub instead of a server connection. Maybe the connect to dialog should give a choice whether to establish a chat connection or a server connection...
BTW, I couldn't find any way to manually add an IP to the Host Cache, which should be possible IMHO.
EDIT: How can I use a username and PW on a DC++ server?
