  • CSE home directory issues (resolved)

    Posted by Raymond Wong Friday 16 April 2021, 05:21:26 PM.

    I have been informed by ss that you can now log in to CSE machines and resume your assignment work.

    If your home directory has been affected by this issue (all files disappeared), please follow the instructions to restore (using tkrestore). If you have problems using tkrestore to retrieve your missing files, you need to contact Helpdesk told me that they will be around after hours and during the weekend as well.

    If your home directory has been restored successfully, and you experience this issue again from now on, please email and copy cs3311.

    Again, if you have further questions regarding this issue, please post to the webcms Forums.

    Reminder: the extended assignment deadline is now: 5pm Monday, Apr 19, 2021 AEST.

  • CSE home directory issues

    Posted by Raymond Wong Friday 16 April 2021, 11:50:22 AM, last modified Friday 16 April 2021, 12:05:39 PM.

    Dear COMP3311 students:

    There have been home directory issues affecting a small group of students and I have been communicating with them until 4am this morning. However, the problem is still ongoing. CSE system support has been tracking all activities but will need you to stop working on the assignment from now until 5pm today (I will keep you updated if there are any changes).

    I have more than 100 emails related to this issue received this morning. If you have sent me one or a few, it's unlikely that you will receive my reply individually. So what I would like to ask you to do is:

    1. Stop logging into CSE machines and stop working on your a2 now until 5pm today (and check WebCMS Notice around 5pm).

    2. After 5pm, if you need to restore your missing files, follow the instructions of Robert's email in the notice below. If you have problems to restore the files, contact helpdesk@ cse as Robert suggested. Please do not ask cs3311 how to fix the problem. It is beyond our access privileges to fix / do anything for you. It has to go to ss.

    3. The a2 due date will be extended to April 19 Monday 5pm for ALL students . I will update the give submission system shortly.

    If you have further questions, please post to the Forums.

    Regarding this issue, only email cs3311 or me unless it is necessary. Thanks for your assistance and I apologise for the inconvenience.

  • The email from ss

    Posted by Raymond Wong Friday 16 April 2021, 02:42:40 AM.

    Some students told me that they have not received any emails from Robert (ss@cse). I'm posting his email here:

    Dear CSE Students,

    Roughly thirty CSE students have noticed this evening that their CSE
    home directories have been emptied.

    The CSE Computer Administrators are working to find the cause of this
    problem and stop it happening. For now more people are reporting this
    problem, so we do not think it has stopped happening, yet.

    It has only happened to a small proportion of the people who logged
    into a CSE computer this evening.

    If this happens to you, you may notice that your CSE desktop resets to
    default when you log in. Almost all of the files will have gone from
    your CSE home directory.

    If you have lost assignment files, you should tell your tutor or
    lecturer about that.

    Backups of CSE files are made every night, so you can get back a copy
    of your files from yesterday, if you need them. See:<wbr>FAQ/Restoring_files_from_backu<wbr>p/

    If you need assistance with restoring files, or resolving other
    technical problems you should send an email to:

    If you observed anything unusual happen before you lost your CSE files,
    please tell us about that too.


    If this has not happened to you, now is a good time to make an extra
    copy of any important files in your CSE account. You might copy them to
    your home computer, or your UNSW file space which, on CSE computers is
    at: /unsw/<zID>
    (See:<wbr>FAQ/UNSW_File_System/ )

    Yours Sincerely,
    Robert Doran
    for CSE Computer Support

  • Issues on some CSE home directories

    Posted by Raymond Wong Friday 16 April 2021, 01:39:40 AM.

    You have all received an email from Robert (ss@cse) that some CSE students have noticed this evening that their CSE home directories have been emptied. SS is currently logging and tracing the activities on CSE machines and investigating the issue. If this has happened to you, please restore your files from the every night backup by following the instructions described in his email.

    Please also email with a screenshot of the issue. We may not be able to quickly respond, as we have been receiving lots of emails. We will pass your ziD and details to SS for their investigation. If you have been affected by this issue, you will be granted a 48-hours extension (i.e., due on Sunday 5pm).
