Alright, basic information first. At college, they won't give me the WEP key to the wireless system just as a 'precaution' or something like that... A little irritating, but I get by and use a local network which is unprotected for the internet. There is often a machine on the network called echo1, which I suspect to be the owner of the network's computer. Then I just forget it's there. Now today. I'm at home, and I'm in the Finder, and I notice in the sidebar underneath Shared there is a machine named echo1. I cannot access the machine, and I'm not sure what's going on here. However if I click on Network, the machine doesn't show up. Is there some way I can identify the machine, it's IP address, how it's accessing the network or any information about what it's doing in my shared area? Is it just some malfunction of my computer or the Finder? Thanks for the help.
