Then, I can help you since I am using Mac (OS X) to remote into a server (happens to be a windows server, but the client config is the same)
1). Install the Aware OS X version on your client
2) . Go to Applications and Right click on your AwareIM application and select Show Package Contents
3). Navigate down to Resources / Java and copy the JAVA folder to a folder where you plan to run the aware client from (there is more stuff than you need, but this is easy)
4). Now, in that folder, edit the bin/startupOptions.props file to set the right IP address (like it tells you in the manual)
5) the bin folder has the ClientStarter.sh
You should be all set (assuming you have the appropriate ports open on your firewalls.)
Good luck
Bruce
