Using Webui...

edit

The problem I was encountering was due to admin privilege's associated with the ubuntu group user. I also have come to find out thanks to a helpful friend of mine ,Thanx Jay... that the apache server is some what secured and that admin privaleges are not given to non-local users. So we did some research and found a helpful command that sets the user {www-data} to admin status. Thus allowing me to launch apps from an external ip. I also understand that this may compromise my security on the server which is why it isnt a default setting to begin with. So to correct my initial issue.. First run roscore, webui.launch and type in terminal 'sudo adduser www-data admin ' then restart the server and possibly roscore and that should do the trick. Im not sure how this may or may not work for others using different versions of ubuntu but I'm using 10.10 and worked like a charm.
