    New members have to wait three days before they can download files.

    I had the same problem. I think you have to be a member for a few days before you have full access to things like downloading and posting.

    Default Cracking Linux/Unix Passwords with John

    I figured I'd test this out and followed the guide. I was able to retrieve my backtrack passwords but my fedora 9 passwords didn't show up. I did the following.

    #mount /dev/sda1 /mnt/fedora/
    #cd /etc/john
    #unshadow /mnt/fedora/etc/passwd /mnt/fedora/etc/shadow >test
    #john test
    here I got the output: No password hashes loaded

    ideas?
    An issue with fedora maybe?

    I am working on updating the guide. It might be an issue with fedora 9 I don't know. I will download a live cd of fedora 9 and get back to this posting later this week or early next week. Can you please post the contents of test
    (i.e. # cat test)?

    Thanks,

    I added the edit and cut out some of what looks to be hash although the error said there wasn't any present but you get the idea. Thanks for taking the time to look at it

    An issue with fedora maybe?
    OK I had some time this morning and it is not a problem with fedora 9. I booted off of the Live CD and did the following:
    adduser usera
    passwd usera (password)
    /mnt/bt3/usr/local/john/unshadow /etc/passwd /etc/shadow >/hash.txt
    /mnt/bt3/usr/local/john/john /hash.txt
    password

    The full paths are because I booted from a cd and ran john from the hard drive. It looks like the unshadow did not work. Here is what my hash.txt looks like for usera:
    usera:$1$qLMNTNhW$yyWg.EzvoMyCofteUP8g0.:501:501::/home/usera:/bin/bash
    yours is
    DrWalter:$6$L19nNdIR-EDIT$iE2XFFsfBTFfAUCs.u0RZlxbPL2x5L45cyx2oD8Zvs7Sr .Treb$

    As you can see you have some missing fields so john doesn't think your hash is valid. Try it again and pay attention to the output of the unshadow command.

    If you need any more help let me know and answer this: Are you using a regular Fedora install (download or install from a fedora mirror) or is this a customized Fedora based installation? What command did you use to create the user?
