The mac is a Two 2.26GHz Quad-Core Intel Xeon Mac Pro and the Linux Box is
Ubuntu Server Edition 9.04. The Mac has the ethernet interface to connect
to the network and the linux box connects via a wireless adapter (IOGEAR).
Please help me any way I can fix this issue. It really needs to work for
our project.
thanks in advance,
regards,
pallab
