Hey hey, sounds good. How are you finding the dual core atom with FreeNAS? Any problems? I doubt you'll get any with performance, the single core version I've got heardly breaks a sweat with day-to-day file serving and proxying.
It's more than enough, and definitely overkill for basic file sharing like you said. The only time I see any benefit of the extra core is during PAR2 repair on incomplete usenet downloads, as that's the only job this box does that's limited by CPU rather than network/disk I/O.
Also that's one of the main reasons I opted for FreeNAS - the simplicity of adding packages with the added security of BSD was enough to win me over. Sure Windows software is easy to install, but having everything presented in a web page or on a command line is much nicer and better for my needs. Setting up torrents with an iPhone remotely etc.. Or logging in via SSH to start stuff up/shut stuff down. Again, do-able over the iPhone whereas a Windows setup would take a lot more jiggering or need VNC/TS running.
I'm a total noob to FreeBSD, but it's very similar to Linux (including the package management) so didn't take me long to feel at home with it. I'm really impressed with SABnzbd+ too. As a longtime Newsbin (Win32) user, I was concerned that I would find it lacking in some way, but as it turns out, it meets my needs perfectly.
I'll have to look into SSH via iphone. Only ever used VNC/RDP via my iphone in the past. What SSH client are you using?
