Error during command authentication.

Error - unable to initiate communication with LISTSERV (errno=10061, phase=CONNECT, target=127.0.0.1:2306). The server is probably not started. LISTSERV - MACSCRPT Archives - LISTSERV.DARTMOUTH.EDU

How can I get the state of another Mac machine on the network? I.e.,  
It's in SLEEP or it's OFF?

Regards,

Chuck
