    I'm having problems with security on the wireless network (WEP protected) I have with my flatmate's XP PC mainly that he is able to access all my files and place new files into the folders (no malicious intent, thankfully). I followed the guide here:

    http://forums.macrumors.com/showthread.php?t=54704&page=13&highlight=network

    As a result he knows the password to my Macbook account so is there a method to network that doesn't involve me giving him my password. What I want to be able to do is just share the folders I want NOT my entire Home directory :confused:. Any help would be greatly appreciated :)

    BTW my flatmate is the network admin.

    I don't think there is a simple way to share particular folders like you can do in Windows, unfortunately

    I'm surprised he can see you entire home folder, though. What do you have enabled in you "Sharing" system preferences? I was under the impression that when you enabled file sharing, only the files in your Public folder are openly accessible.

    Or maybe I'm confusing File Sharing with Web Sharing?

    Anyway, as a first step please list what Sharing you have enabled so far...

    Thanks for the reply, Imalave.

    Basically when
    I entered the WEP I could connect to the network and access the net, however I could not see any of the shared folders on his PC (Finder>Network) so I tried the method in the post above and now can access them, however, he can now access my whole home directory

    I've already changed my password and turned off ALL filesharing in Sharing...to no avail, he can still see all my files and create new files in my Home directory!:confused: BTW my firewall is supposedly off.

    Sorry he cannot access my whole Home directory rather he can see Music, Videos, Desktop, Public etc. and can also place new files into these folders (annoying as he can put files onto my desktop).

    Hi, there are many, many pages to that thread you linked to. Can you cut and paste the changes you made?

    How is he viewing and creating files in your home directory? Does it look like a regular Windows Share on his computer? Is he just able to right-click on your home foder and say "Create New Folder" or "Create New File"?

    Do you have *all* sharing turned off, including FTP and Web sharing? Even Internet Sharing? Just covering all the bases.

    Hmm...that is still very strange. I thought only Public was accessible.

    FYI, if you want to share other folders besides just the Public folder, I seem to recall that the way you can do that is by creating a shortcut to anything you want (be it a file or another folder) and putting it in the Public folder...

    All file sharing is off.

    Puzzling, that shouldn't be possible, is the firewall (System Preferences==>Sharing==>Firewall) on?

    EDIT: Disregard what I wrote...he can still see my computer and folders as I described above and insert new files.

    Eraserhead, the firewall is on with no boxes checked.

    Sounds very strange, almost as if you've been hacked which is worrying, if none of the boxes are checked and the firewall is on that should be basically impossible.

    Is everyone using XP or OS X? If so it is worth switching the Wireless network security to WPA (if possible) as WEP isn't actually secure and is only really a deterrent.

    A bit more info, I got confused earlier on...basically he can't access my computer via My Network Places anymore...he can still access my computer and folders through my IP though.

    There's just the 2 of us on the network, he's using XP Pro and obviously I'm on the Macbook.

    I don't know, I'd go for my WPA suggestion though if you can.

    Can you load up and screenshot Directory Access (/Applications/Utilities/Directory Access)? I believe you may still have some stuff open with that.

    Ok, so I read through the instructions that you followed. So did you follow all of these instructions? Which of the above steps did you undo? You unchecked "Windows Sharing", right?

    What about the "Directory Accesss" settings? I'm not familiar with those settings, but have you tried unchecking everything under "Directory Access"?

    Can you provide Screenshots of your Directory Access settings as well as your Sharing settings?

    Also, can you post screenshots of what your machine looks like on your roommates computer?

    WPA vs. WEP has nothing to do with file sharing, though. He and his roommate are both connected to the same wireless network, so they absolutely SHOULD be able to see each other's computers, even with WPA. The issue is the file access.

    So what is he typing in exactly? Does he just put something in like \\10.0.0.3\ in his Explorer window? What exactly is he doing? Or does he put something like file://10.0.0.3/ or ftp://10.0.0.3/?

    True, sorry it's not important right now, my feeling was that with this problem the fact that the wireless network isn't secure means others could get access too.

    All I've undone is uncheck all file sharing (plus untick my account from the "Accounts" button) and changed my workgroup back to the default "Workgroup".

    As requested:

    Will try to get a screenshot on my flatmate's side of things too.

    Try this, actually: turn all sharing settings ON and then turn them OFF again. Maybe somehow one of the Sharings is stuck on ON even though the Preferences window is showing it as OFF.

    No idea, try installing Netbarrier a third party firewall (free trial), it has never been possible on my computer before.
