Ok, I did not mean to sound so pathetic, sorry guys.
I have connected to the Zaurus both by USB and LAN, and the Zaurus comes with SSH installed. I am able to copy items to and from the Zaurus over both connections, but I cannot seem to sync using ZmacSync.
I have checked the IP addresses on both the mac and the C1000 and they are correct.
Am I missing something obvious?
p.s. thanks Macus for responding
