/diy/ - Do It Yourself

Hey Han/diy/men,

I'm trying the /diy/ fileserver and it's my first time working with Linux, a fileserver/ftp, and ssh. I need some help though, I'm using the guide I found here and I've got some questions.

1. I have mixed ram. Three 1GB DDR2 sticks, all different speeds/brands. Normally I've kept all the sizes/speed/brand the same in my rigs. Is it alright to mix and match?

2. I have a 80gb hdd I want to add to the 120gb hdd I've got already. How can I work with this for the fileserver, if I wanted to make the max space 400gb (Can I do raid 0 with two different sized hard drives?)

3. I'm inexperienced with SSH. What program's got the most user-friendly UI when it comes to accessing the server? I downloaded Putty just because the guide said so.

4. If I follow the guide, doesn't it mean everyone has access to my FTP? Is there a way I can password protect it? (Back in my Counter-Strike days, I remember accessing the FTP via browser and it had a log-in. Do want.)

Thanks bros.
