gdomap is the service that GNUstep uses for distributed objects.
gdnc is the service that GNUstep uses for distributed (broadcast) notifications.

They are both started on demand.  If they're running in your jail, then it most 
likely means that something inside your jail has started them.

Both gdomap and gdnc are intended to allow messaging between computers on the 
local network and so will bind to a public IP.  Given that neither of them has 
had any kind of serious security auditing (or even anyone trying to fuzz their 
parsers), I'd strongly recommend firewalling them off from the outside world.
