I think your problem is mDNS is failing. See thread
http://www.chiefdelphi.com/forums/sh...d.php?t=132597 where this is discussed at some length.
The root cause appears to be your PC and the RoboRIO deciding they want to use IPv6 instead of IPv4 -- the mDNS lookup is returning a v6 address instead of v4. This unfortunately doesn't work for the Eclipse ANT script I think or for the DS.
The solution we found was to disable IPv6 on the Laptop/PC (or Mac presumably) for that interface. Couldn't figure out how to disable it on the DLink. Presumably you could kill it on the RoboRIO in Linux config but I don't know offhand how to do that.
