[lug] NSLU2 as backup device

[Bear Giles]

A related followup - I've set up user-space NFS and an Apache server for 
static content.  I haven't done performance tests but it appears to be 
fine.  I haven't reinstalled SAMBA.  I know it's used in the production 
system, but you lose that when you unslung it to run Debian.

Encrypted file systems (since the slug uses an easily stolen USB 
drive):  I haven't been able to figure out how to modify an embedded 
kernel so I haven't tried kernel-based encryption.

I know that CFS installed but I need to do more research on it.  I'll 
almost certainly want to run the encryption on the client side.

(CFS is a encrypting variant of NFS.  It written by one of the heavy 
hitters in the crypto world (Matt Blaze), so it's not some college 
student's class project.)

In any case the usual concerns with NFS partitions apply.  I'm sure 
everyone has a hardware firewall on their broadband connection, but LANs 
should still be considered suspect if you have a wireless hub.  I'm 
using WPA but still have the client IP addresses fully specified.

I also looked at SFS, but it looks like that doesn't encrypt the disk 
itself.
