Hi all. I have a program I want to allow a couple of friends to get from my computer. I have several questions about this. 1. Since I am using an airport extreme with a wireless network, I assume I have to set up port forwarding. Is this correct? 2. I did set up a port forwarding scheme that works. However, I have a question about port numbers. Is the public port number one you make up and is the private port number one dependent on the protocol being used? If so, how do I determine what to use for the private port number? I know from my linux experience that 22 is the usual port for ssh but I don't know anything about port numbers with the Mac other than this. Also, the instructions I read indicated that when I set up the port mapping in Airport Utility I'd choose a service but I don't see any opportunity to do this. I do have file sharing on in system preferences > sharing. 3. I could put the programs I want to share in my Public folder. However, I have discontinued .mac/mobileme so I'm assuming that I can no longer have people access my public folder by finder > go > idisk > other user's public folder. Am I correct in this assumption and if so can this be done by goto server or is that still only for peopole within the network? 6. I also thought of allowing ftp downloads though I realize information isn't encrypted. If I went this route, how would I control what folders people are allowed to access? Is this taken care of in the sharing options or do I have to do more than this? 5. Miscelaneous: Any other information on safely having people copy or download from my computer--but obviously only what i want copied or downloaded!!!--would be appreciated.
