I set up SFTP instead. I don’t have the computer hooked up to a monitor, keyboard, or mouse. I use it to backup our laptops as well as for file transfers.

I use thatip.com for dynamic DNS services. It’s the cheapest service that has all the features I want. I have a cron job that updates my IP address every few minutes, although my IP (99.172.173.172 at the time of this posting) hasn’t changed since I started the web server over 2 months ago.

So did you bother setting up FTP access for yourself, or do you just do everything on the actual machine?

And how are you dealing with the dynamic IP address, out of curiosity?
