Thread: disk permissions

  1. #1

    Default disk permissions

    You do not have the permissions necessary to view the contents of "data".
    and the same error for the other partition "data 2"
    These 2 partitions are made with fedora 12.

    as you know permissions are tied to user ID, though the word/name you
    use as an ID might be the same on both Fedora and openSUSE, both
    systems actually use a UID _number_ to track permissions...

    you can see yours UID in openSUSE via YaST > Security Users (mine this
    second is 1000)

    so, you can have the same _name_ on both openSUSE and Fedora but in
    actuality have two different numbers, and therefore NOT have permission..

    that is if your ID _name_ on Fedora is not associated with the same
    UID number you have on openSUSE, you can't get in..

    i think what you can do is associate your _name_ on openSUSE with the
    UID used on Fedora, but sorry, i'm not sure how to do that..(dumb
    because i stick to one distro at a time)

    I run into this all the time when I try to transfer a DB2 backup between
    servers. The default UID, usually 1000 for the first user defined during
    installation, is incremented and assigned as the users are created.
    Creating additional users in a different order one different servers
    usually ends up with the same user on two different servers unable to use
    the backup on both machines until you use root privilege to re-assign the
    UID on the backup files to the one applicable to the server of the moment.

    Using Yast doesn't seem to work if you use it to change a user's ID - it
    never gets the new UID for all the affected files in the user's home
    directory. I've gotten to the point that I keep a script to create the
    users when the same person has accounts on multiple machines just to avoid
    the issue.

    interesting...i wonder if you have the time to see if there is a bug
    filed against YaST on that, and if not do so??

    Guilty ;-)

    I've only run into the problem with Yast and changing UID in one
    circumstance and that was with the DB2 instance owner so I'm reasonably
    certain that the real problem is in the DB2 config files (arcane critters!)
    rather than with the permissions in the file system. The other part of
    permissions on backup media doing transfers is straight forward and working
    as it should. The one filesystem sets ACLs on the files and the two
    machines use different UIDs for what should be the same user/group so the
    original user/group is unknown to the second machine. I just have to change
    them via chown when I hit a strange machine.

    Not really a bug, just a nuisance.
