SSHFS using Realcrypt as a container.

The idea behind this approach is to create a volume container on the server (bud) and access it from a remote system via sshfs/fuse. This will allow remote file level access while encrypting the data on the server. The keys and decryption algos will only be know by the client user. If this works correctly, Truecrypt can be used on the client to access a realcrypt volume remotely.

Set up on bud.

1. Install Realcrypt for Suse. (See Log)
2. Add user to Realcrypt group moduser
3. Configure an empty container: see http://altoptions.wordpress.com/2008/01/16/realcrypt-howto-part-1/
4. Attempted to mount container, recieved an error: Error: fuse: device not found, try 'modprobe fuse' first
5. Googling indicates a reboot may be needed. Will check with the Sysadmin list first.
6. Mounted via sshsf to my home machine.
7. Mounted with truecrypt on windows. Worked!
8. Formatted as NTFS - worked!
9. Transferred a couple of files.
10. This appears to work.
