NSLU2 problems with NTFS permissions

    I am on my second NSLU2 (first one was replaced with this one because of apparent problems).

    I am using it with two Win XP Pro laptops through a Linksys wired/wireless router. I have connected a Maxtor OneTouch II 200GB disk which I used to use a lot, and it is NTFS formatted.

    If I enable guest logins and set the failed logins to default to 'guest' option, I am able to map drive and view all folders and files. As soon as I disable guest logins, I am unable to even connect to the device/drive.

    From what I understand, if I have no EXT3 disk, I cannot do much with users and groups. Is that correct?

    Also, if I want to secure the drive, what is the best way to do it? What I want to avoid is 'guest' and 'everyone' being able to access my hard drive.

    Any help is appreciated. I can provide more details if you need to.

    Yes, that is correct. To use shares/groups/users and your own ID/PW, you must format the drive to ext3 (which of course erases everything on it).

    You can put a second drive on the NSLU2 formatted to ext3 and the one you have now in NTFS. The NTFS drive will still be open to everyone. Plus you won't be able to do a drive back up from the ext3 to NTFS drive because it isn't ext3. Also the NTFS implementation is buggy. You will probably see disconnections or interrupted transfers if you are trying to back up large files or folders to the NTFS drive from your computer.

    So the bottom line is don't use NTFS if you really want to use the full capabilities of the NSLU2. Maybe (hopefully) Linksys will post a new firmware that fixes these problems and have NTFS drives working properly. Before R63, there wasn't even this buggy NTFS capability.

    Thanks for the info/tip.

    So at best, if I want to keep NTFS, I will have to live with the 'guest' and 'everyone' groups that come out of the box with the NSLU2?

    Actually, once I map network drive, I can (through windows) remove 'everyone' as an allowed user. Would that make it any secure?

    Also, I changed the 'guest' password through the web config utility.

    And just fyi, I am not trying to make it secure within the home network, since it is only my wife and I. I am more concerned with someone from outside the network somehow hacking into the nslu2 and being able to access the data.

    Anyone that can reach the NSLU2's GUI will be able to see all the data on the NTFS drive because it will all be public access.

    As long as you have a router that is protecting your LAN from outside access, there would be no problem with an NTFS drive's lack of private access. It is only when you start allowing visitors from outside your LAN or when you are trying to allocate separate file areas for users on your LAN is there a concern about shares/groups/users.

    There is one other problem with using NTFS drives. The writes to them simply aren't reliable when large transfers are attempted. If we knew what the transfer size limit was when it fails, then you could restrict your usage to smaller file transfers, but we don't.
