re-activate dockstar (5 replies)

Hi there.
I am trying to re-activate a dockstar
So i followed this instruction:
http://archlinuxarm.org/forum/viewtopic.php?t=1323

everything seems to work.
But: Now I don't know how to log in over ssh (user? pw?)
the dockstar is reachable over ethernet and ssh is responding

Whats the best way now to proceed?
Is there any other image which i can install over tftp and where i get a better manual?

thanks in advance!
Kind regards
