Previously I couldn't even ping it; now it appears to respond to pings, but I can't SSH into it on the port you previously gave me. I assumed you were just AFK or something so I didn't want to bother you about it until now :) -- You received this message because you are subscribed to the Google Groups "sage-release" group.
