Basically, the "real" answer is that you cant. And personally, I wouldnt want to be be sitting in the server room using the HMC for anything.

If you mean using X (e.g. exceed on your pc) to use the HMC, there is no need.

For scripting you setup ssh so that you can excute scripts from an AIX host and/or other remote system with ssh capability. For the GUI work you download the webclient.

The URL for this is: http://hmc.domain.me/remote_client.html

or just use:

wsm -host hmc.domain.me

from an AIX prompt in an exceed window.
