MiShare is a secure collaborative file transfer system provided by MCIT. The MiShare infrastructure provides a method approved by the UMHS Compliance Office for UMHS personnel, non-UMHS business partners, and researchers to securely transfer files, including files that contain electronic Protected Health Information (ePHI), protected research data, or other sensitive information. Files are encrypted while being uploaded or downloaded, and are encrypted while they are on the MiShare server.


File Size Limitations

You may transfer large files securely using MiShare. We regularly transfer files with sizes in the tens of Gigabytes. There are some conditions where you may find limitations to the sizes of files that can be uploaded or downloaded to/from the system:

  1. If you use a web browser and do not use the Upload/Download Wizard, you will typically have limits of about 2 GB that can be either uploaded to or downloaded from the system.
  2. If you use sFTP to upload or download a file, we have not seen any limitation to file sizes.
  3. If you use a Java-based browser (ie, Firefox, Chrome, Safari, ...) and you use the Java Upload/Download wizard and you select to have the wizard compress the files you send into a single .zip file, we have seen that there is a limitation of about 4 GB. The limitation is in the code that is being used to zip the file. The vendor is working on fixing this limitation, but we have no timeline as to when we may see the fix. The vendor has told us that the ActiveX based wizard used by Internet Explorer does not have this limitation. Workarounds are:
    • Use a stand-alone application such as Winzip or 7-Zip to compress the files to a single .zip file and then use the Upload/Download wizard to send the file.
    • Upload the files in groups of files that are less than 4 GB each and allow the wizard to compress the files as multiple .zip files.
    • Or do not select to have the wizard compress the file into a single .zip file.
  4. If you are using a 64-bit browser, such as "Internet Explorer (64 bit)", we currently don't have an available upload/download wizard. In most cases you will also have installed the 32-bit Internet Explorer, you may have to use that along with the upload/download wizard if you need to transfer files larger than 2 GB.

 

What is the Upload/Download Wizard?

  • The Upload/Download Wizard is a small application that enhances the ability to transfer files. There is a small active-x wizard available for Internet Explorer, and a small java application for Firefox, Chrome, Safari, and other java based browsers. Among the things that it adds are:

    • The ability to transfer large files. Without the wizard, file size is limited to something a little larger than 1 GB. Using the wizard we are able to transfer files in the tens of Gigabytes.
    • The ability to drag and drop files or multiple files or folders into the wizard window
    • The ability to zip sets of files into a single file to make it easier for the recipient to download
    • Error checking. Using the wizard, you will see the notation "Integrity Checked" on the logs of file uploads and downloads.
    • The ability to pause an upload and continue it if your connection is broken. Note that partial uploads are purged from the system late each evening, but you can resume the upload any time before that cleanup is performed.

    We highly recommend that people use the wizard.

     

    Wizard isn't available for 64-bit browser

  • There is currently no wizard available if you use a 64-bit browser. Most browsers are currently 32-bit applications even if you have a 64-bit operating system. On Windows 7, you will see both a link for "Internet Explorer (64-bit)" and a link for "Internet Explorer" in your programs list. If you use the one that simply says Internet Explorer, you can use the Upload/Download Wizard.

    Problems installing the Wizard

    Under some conditions, you may see errors when you try to install the wizard. It may display a box and say "The wizard has not downloaded" and ask if you want to continue waiting or cancel, for example. They typically is a problem with Java running on your workstation. First, try restarting. If that doesn't fix the problem, then exit all java enabled applications and clear the java cache. Follow these steps to clear the java cache:

    1. Exit all browsers or other java applications
    2. Go to Windows Control Panel and launch the Java Control Panel
    3. In the Java Control Panel > General Tab > Temporary Internet Files section select "Settings..."
    4. In the Temporary Files Settings dialog select the Delete Files... button
    5. In the Delete Temporary Files dialog select to Delete Applications and Applets as well as Trace and Log Files and click OK
    6. Click OK and OK again to exit the Java Control Panel
    7. Launch your browser and try to connect to MOVEit DMZ again selecting to install the Java Wizard
    8. if this is unsuccessful try upgrading your Java to the current version (you can download the current version from http://java.com) or uninstall and reinstall java to the current version.

     

     

    Firefox has problems downloading the Upload/Download Wizard

    If you are using Firefox, you may see a pause and then a window telling you that the wizard was not downloaded and asking if you wish to wait. This may require you to clear your Java cache as above. But there may be another cause. Due to some security vulnerabilities in Java itself, Firefox disabled some versions of the Java Add-on for Firefox by default. You can check the version of the Java by choosing Add-ons from the Tools Menu. The version of the Java Add-on will be displayed. If you have versions below 1.6.0_31 or between 1.7.0 and 1.7.0_2, then Firefox has disabled the Add-on for security reasons. If the add-on is disabled, it will prevent the upload/download wizard from downloading and/or running. We recommend that you upgrade your Add-on to the current version. Click on the "More Information" link in the Add-on manager window to be taken to the Firefox details of this problem. If you must continue to use the older version of the add-on, you must click the "enable" button to enable java to run and then restart Firefox. In that event, be aware that you are enabling something that has security implications. .

     

     

    Login Failure

    There are two common reasons why login to MiShare might fail: incorrect username and incorrect password. If you know the correct username, and try three times in a short period with an incorrect password, the system will lock your account for 15 minutes. This is to prevent brute force attempts to break into your account by trying to guess your password. If you continue to try to login while the account is locked, your IP address will be prevented from logging into the system with any account for a period of time.

     

    UMHS Personnel with a valid Level-2 account

    1. Wait 15 minutes if you have locked your account using the wrong password.
    2. Be sure to use your uniqname and your Level-2 password
    3. In the login window, use just your uniqname, not uniqname@med.umich.edu
    4. Note that if you received a notice that someone in UMHS has sent a package to your uniqname@umich.edu, then you would have to login with the login name uniqname@umich.edu and the password you were sent. That account, effectively, is an external user account (see the information below for External Users).
    5. For password issues and to reset your password, see the Identity Management help page (click on link)
    6. Call the MCIT Service Desk at 734-936-8000 if you need further assistance.

     

    UM Personnel with a Campus Kerberos account

    1. UM Kerberos account logins can't be used at this time to login to this system.
    2. You can login to MiShare if you have been sent a package by a UMHS person. In that case, you would login to the system using the username and password that you were sent at the time the package was sent to you. Your username would be of the form uniqname@umich.edu. See the section below for external users.
    3. You can send packages to any UMHS person using MiShare. From the MiShare main page at http://mishare.med.umich.edu, click on the link under the second blue banner that reads "Send files to UMHS personnel" and use the recipient's uniqname to send them a package.
    4. Call the MCIT Service Desk at 734-936-8000 if you need further assistance.

     

    External Users - non-UMHS Personnel who have been sent a package

    1. If you have locked the account guessing the wrong password, wait at least 15 minutes before attempting again.
    2. You have been sent an email with the information about how to login to the system. Remember that upon your first login you will be requested to change your password. Your username will be the email address that the package was sent to. Remember to use the new password that you set.
    3. Your account will remain active for at least two weeks after you last used it. After that, if you receive another package from a UMHS person, a new account may be created with a new password, and you will receive another email with the login credentials. As before, you will be required to reset the password when you first login.
    4. You can send packages to any UMHS person using MiShare. From the MiShare main page at http://mishare.med.umich.edu, click on the link under the second blue banner that reads "Send files to UMHS personnel" and use the recipient's uniqname to send them a package.
    5. Call the MCIT Service Desk at 734-936-8000 if you need further assistance.
