With the default Linksys firmware, if the NSLU2 has only FAT or NFS drives attached to it, the default password for admin cannot be changed.
In addition its only possible to have one share and there cannot be any access privileges set from the nsul2 for the share.
On the local subnet, the share is open for anyone to read or write. Care must be taken not to expose the nslu2 to the web
in this mode as data can be compromised.
