this looks useful, so i had a look for the linux equivalent. turns out there's a command line utility called nethogs that does something similar (it shows bandwidth per process, but not addresses). for opensuse you can get it here - http://software.opensuse.org/search?q=nethogs&baseprojec...
another command, iftop, shows connections, but not processes (that's in the standard opensuse repos).
