Unable to connect to Magma server

I'm on Mac OS X - running 2 VM's one for the server, one client.

Server is setup, initialized, seems happy-ish. I'm using latest dev image + magma server + BTree.

MagmaRepositoryController create: 'magma' root: BTree new (MagmaServerConsole new open: 'magma') processOn: 1010

Seems fine.

Second image I try:

| mySession | mySession := MagmaSession hostAddress: #(127 0 0 1) asByteArray port: 1010. mySession connectAs: 'magma'. mySession

and I get an error - connection timed out. Is there some kind of ping I can send the server via telnet to see if it really is alive?
