Free Nas and a question

[FFE]

I'm a newby just looking for some quick help

How hard would it be to set up a Free Nas ( or any other linux distor) at a remote location and have it back up my pc's.

My parents want a computer to back up there laptop and desktop. So they want me to build a pc, no problem there. Since I'm setting up the PC for them they said I can use it to backup my files also. So my question how hard would it be to set up the system to back up my pc's(3 of them). I'm guessing I would have to set up port forwarding on my router and probley there router.

We both are using Lynksis WRT54G routers.

The 'getting it working' bit is easy, more of a concern is getting it secure if you are accessing it over the Internet. You realy should use a VPN. I have had some success with OpenVPN, so as far as I am aware. It's prety decent, just a bit hard to configure and setup, the how to on the OpenVPN site is prety helpful.

If you load some custom firmware for your WRT54G's, like the DD-WRT VPN build, you can setup a always on VPN between the 2 routers without the need for a seperate vpn server. Gonna be slow as hell over the public internet though.

would SSH provide a sucure enough form of transpher. The SSH client my school uses, has a file transphere option

SSH would, but it wouldn't be paticulaly conviniant. The best option is VPN.

If there isnt any sensitive information, no sense in encrypting it.

Yes there is, you don't want people brute forcing your NTLM passwords. If you have to connect to a VPN first, it makes brute forcing the NTLM password imposible befor brute forcing a 1024bit RSA key (for example).

that will be a little difficult to crack
