    This is a simple thing you've probably already thought about but you can only connect computers directly to each other if you use a "Cross" cable. (A cable with TX and RX pairs reversed).
    Macs are Auto MDI/MDIX - ie you can use either a 'cross' or 'straight' cable to connect between 2 of them.

    However, some hubs/switches may not be - so best to use 'straight' patch cables.

    Well, you're right. For some reason I was under the impression that G5 Macs were not Auto MDIX.

    Apparently since G4 Apple has chosen Auto MDIX ethernet ports.

    I have switches in my racks so I don't need cross cables but if you are not using a switch or hub, you will.

    Also, if no other computers are connected except the two you are using then you are also running into the fact there is no DHCP server. For this, just manually assign IP addressed to each machine.

    Example settings are 192.168.0.2 for first machine and 192.168.0.3 for second machine. Also set the subnet mask to 255.255.255.0 which shouldn't matter but okay to do anyway. Don't set a default gateway and don't set DNS servers. You won't need them.

    Once you do this, you should be able to connect.
    you dont need crossovers on macs for many years - they autodetect the ethernet connectivity-

    it can be more of a problem if you do use crossover cables -
    and it can be a problem if another device senses with a different delay. then the autonegotiate can get in the way - i suggest when using dumb artnet boxes always using a hub - with another mac- its not usually a problem.


    also - you dont have to have any ip address set up for syncing - it uses a broadcast protocol that is not sensitive to address ( as long as the mac has some address the actual address doesnt matter )

    Hey Richard, I am curious to some of your statements and would love it it you could clarify what you mean. I'm a little confused.

    What do you mean by senses with a different delay? Are you referring to issues with packet collisions?

    Are you referring to auto-negotiate in Catalyst or from a switch?

    Quote Originally Posted by samsc View Post

    Do you mean using a hub as opposed to a switch? Or do you mean using a hub as an intermediate step between the MAC and the Artnet device?

    A couple other questions...

    1. Is there a way to adapt the software where a user can choose which Ethernet port?
    2. How about a way to use Catalyst as a DHCP server?
    3. How about a way to narrow Catalyst Control so it's not a full subnet multicast?
