For granting access to the system, the 220 has the ability to create user accounts. Figure 8 shows the user creation screen.

Note that the created users can be designed as either a normal user or an administrator, who has access to the 220's configuration pages. Note that the creation of User Groups is not supported.
Once you have the disks configured, you can set up logical shares such as Music, Video, Backup, etc. within the disk and give your users access to those shares. Figure 9 shows the share creation screen.

The only network disk sharing protocol on the 220 is SMB. Although SMB is typically a Windows protocol, it's supported on nearly every operating system these days. But for better interoperability, It would be nice to see the use of NFS which is natively used on Linux and Mac OS X.
Under the "Applications" menu of the 220, you can find configuration pages for a number of protocols. Figure 10 shows the setup screen for FTP.

From this screen, you can see various parameters such as timeout values, maximum simultaneous users, character set, etc. Note that the default network port cannot be changed.
