Ok I'm really new at this . Not the old DOS I'm used to. I'm trying to setup my home server using Ubuntu 12.0.4, I've had no success. I have an actual raid sever I'm using. Loaded first HD with Ubuntu 12.0.4, now trying to setup so I can access from anywhere. Remember I'm a newbie so try and keep it simple until I learn Linux. I have my router setup for port forward using 192.168.100 port 21. everything I looked at so far is pretty complicated for a new user. Any help would be great.

Not entirely clear what you're trying to do or what you mean trying to set the server up to access from anywhere.

For the FTP, you'll first need an FTP service. Run:
Find the following by scrolling down the screen:
Delete the # character from that line then press Ctrl+X > Y > enter, then run:
Once it runs you'll be able to log into the FTPd using your Ubuntu server user account.

Once you've done that you'll want to make sure your router is pointing your port forward setting to the right IP. You can confirm the correct IP with ifconfig:
You'll be shown something like the following.
Don't worry about all of it; just look at the interface (eth0, eth1, wlan0 etc) that appears to be the busiest. You're looking for the inet addr. That's your machine's network IP given by the router. Make sure your port forward is set to forward to this IP. The port should remain the same.

Once you've done all of that and it works have a look online for a guide to configuring proftpd to use SFTP (secure).
