Same thing here. I've had some luck downgrading to ssh version 1 (i.e. use ssh -1 server), although this works only when connecting to the mac box from the linux one, but not vice versa. This problem went away after I set up my WiFi router to the linux box by default. Not sure about causality here. But upgrading the firmware on the router broke this again (Netgear MR814v2).
