Linux command to report hardware architecture (i386, x86_64)

Anyone knows the darwin equivalent?

mini mac - can't eject cd while trying to install ubuntu

I was trying to install x86_64 version of ubuntu 9.04 server on my mini mac. However, mac mini can't handle x86_64 and needs i686. But now I can't eject the cd and I am stuck. After some googling I found out that you need to keep the option key pressed while booting up. This brought up a menu allowing me to boot off the hard-disk. Phew!

I found this today (07/20/09) - while booting up press the mouse button to eject the media from your CDROM drive

X11 port forwarding in macosx

I am running KVM virtual machines on ubuntu server host (on a mini mac). To gain access to the VM console from my macosx client, I use ssh X11 port forwarding like below

$ ssh -Y myhost

From within this ssh session, I run
$ xvncviewer

The Y option from man pages brings up the following:

-Y Enables trusted X11 forwarding. Trusted X11 forwardings are not subjected to the X11 SECURITY extension controls.
