Networking with computers outside of LAN
I am looking to do something like a Samba share, but over the internet so any computer can access the file files (read/write) on my computer (in a specified folder) with the correct user name and password. I am aware that occasionally my IP will change, as I have not registered a static one with my ISP, but this is not a problem for me, as on the rare occasion it changes, I can deal with it. Whats more it seems to change once about every year or so, give or take about 9 months :p
Back to the question: How would I setup a folder on my computer to be viewed anywhere by anyone with a username/password in read/write format? Something path they can just enter in their location bar in Nautilus or Firefox or Konqueror... etc.
