Distributed builds not working?

All,

I'm struggling to get Distributed Builds working. Here was my initial setup:

Dual G5 (host)
IP of 10.0.1.1
Mac OS X 10.3.1
Xcode 1.0
Distri-builds preferences set to distribute builds to shared computers. In the list of shared computers I see two entries (one for each processor on my dual G4)
Max num of concurrent tasks set to "Best for this machine (2)"
This machine was also dialed into the internet via internal 56K modem.


Dual G4
IP of 10.0.1.2
Mac OS X 10.3
Xcode 1.0
Distri-builds preferences set to share this computer as a high priority
Max num of concurrent tasks set to "Best for this machine (2)"

The two machines are connected directly to each other via Gigabit Ethernet.


What I tried...

Compile up the AppearanceSample found in /Developer/Examples/Carbon.

At most, I only see two compile tasks in the Detailed Build Results window. I guess I expected to see up to four tasks taking place.

I've verified that File Sharing works a-ok between the two computers. Also, running /Applications/Utilities/Network Utility on both machines shows correct info for "Ethernet Interface (en0)":

IP Address(es) 10.0.1.1 (for G5) and 10.0.1.2 (for G4)
Link Speed: 1 Gb

My Transfer Stats are a bit strange...My Send Errors count and Collisions count are at 0, but my Recv Errors count is very high...currently, here's what my G5 is reporting:

Sent Packets: 4225
Send Errors: 0
Recv Packets: 3717
Recv Errors: 9269
Collisions: 0

As I've been typing the above paragraph, the Recv Errors count has been increasing slowly...it's now at 9276...maybe about 1 error every 2 seconds.

While doing a clean build, I never see the Sent/Recv Packets numbers change at all. The Recv Errors still increment about every 2 seconds.



What I've tried which didn't change anything:

* G5 - Disconnected modem and disabled the modem in my Network Port settings. Only port active was the Ethernet one.

* Had Xcode running on the G4
* Had Xcode not running on the G4
* Had File Sharing turned OFF on the G4
* Had File Sharing turned ON on the G4, but G5 not connected to it.
* Had File Sharing turned ON on the G4, and had the G5 connected to it.
* G5 - Played with max num of concurrent tasks...but the number of tasks that showed up in the detailed build window was always at most what I set it to.



Networking is definitely not my strong-point, so perhaps my network is not set up correctly? Or is Appearance Sample too small a project for Xcode to send out jobs to my shared G4?
