This will allow you to transfer files quite easily. With the help of FileZilla, you can easily setup FTP server. Thus, transferring the files is not much of a problem with the help of FileZilla.

Any OS which supports the FTP is compatible with FileZilla.

Thus, you will not have to worry about the compatibility of different machines. The advantage of the file transfer protocol is that it is a standard protocol. Update: This was the solution to the problem, but some personal help navigating the router port forwarding part was necessary.FileZilla is a software which allows you to transfer files between different computers. Ignore the section in this article on setting static IPs, as that was written for windows, and it's generally better to do that in your router, to avoid conflicts: The specific methods for each router and network setup vary a little, so use this as a guideline.

Here is a nice walkthrough on the basics of assigning a static IP to your server, and additional information on choosing IPs and why: Power outages, modem/router reboots, or expiration of the assignment can cause this to change, and you'll have to find out the new one and give it to your friend again. Note: Your public IP is liable to change, unless your ISP has given you a static IP. You can also use this IP yourself to test it. Assuming you correctly forward the ports needed, going to this public IP will work for them like your current method does for you. You will need to provide your friend with your public/WAN IP address, which can be found by going to a site such as on any computer on your network. The address you use to access the server (such as 192.168.1.101, for example) will not work since they are not in your local network. Assuming that your server is in your home on your home network, and not a VPS (Virtual Private Server, something you'd rent monthly), you need to forward port 22 (the SSH port) and port 80 (the HTTP port) in your router to your server.
