When using a computer in the ITG Labs (Microscopy Suite or Vis lab), your ITG Data should automatically mount as drive Z: (Home), and if you have them W: (CTData) and P: (Groups). However, you can connect to your ITG Data from anywhere in the world using these instructions:

If you are outside the campus network, you’ll need to first connect to the campus Virtual Private Network. (VPN) Installing and configuring VPN is not difficult, please follow the instructions here: https://techservices.illinois.edu/services/virtual-private-networking-vpn/download-and-set-up-the-vpn-client

CONNECT USING MAP NETWORK DRIVE

  • Right click on the 'Computer' or 'My Computer' icon, and select 'Map Network Drive'.
  • Drive: Choose a drive letter not already in use. (Z:, for example)
  • Folder: \\files.itg.beckman.illinois.edu\users\netID (replace netID with your CITES netID)
  • You can also connect to your other ITG folders if you have them: CTData: \\files.itg.beckman.illinois.edu\ctdata\netID, Groups: \\files.itg.beckman.illinois.edu\groups\yourGroupName (replace netID and yourGroupName with the appropriate names)
  • Make sure the 'Connect using different credentials' checkbox is checked.
  • If you want your computer to remember this connection through a logout/reboot, then check the 'Reconnect at logon' checkbox. Most times you will want to do this. If other users are using the same local login account on your machine, do not check this box otherwise they will have access to your files when they login next time.
  • click Finish.
  • Enter your authentication in the form of: uofi\netID (replace netID with your CITES netID), and your CITES AD password.
  • It is *critical* that you enter in uofi\ before your netID. Other domains such as uiuc\ will not work.
  • click OK to submit your authentication
  • A window to your ITG data directory should then appear.
  • You should also see the new Z: network mount every time you open 'Computer' or 'My Computer'.
  • If you want to remove the network mount, just right click on it and select 'Disconnect'.

If you change your CITES AD Password you must delete the old mapped network drive, it will no longer work because your password is different. Once you delete the old Mapped Drive you can reconnect another one with the your password.

PROBLEMS CONNECTING WITH WINDOWS?

Sometimes a Windows computer outside of ITG's network might have trouble connecting because it is repeatedly trying to connect with the wrong domain. There is a fix!

  • Open a command window (start -> cmd)
  • Run the command: net use
  • You should see a list of network connections currently on your machine
  • One of the network connections is the "bad" ITG network connection, we need to delete that connection
  • run the command: net use /DELETE \\files.itg.beckman.illinois.edu\users\netID (replace netID with your CITES netID)
  • Once the bad network connection is deleted, you can now try to reconnect
  • IMPORTANT: make sure to connect using the Map Network Drive utility (instructions above), and make certain to check the box "Connect using different credentials". Also make sure to use the username: uofi\netID. The uofi\ is critical. If you leave it off you will create another bad connection.

Using a Mac?

  • Simple! Just goto the Finder menu and click Go -> Connect to Server
  • Enter in the new server as: smb://files.itg.beckman.illinois.edu/users/netID (replace netID with your CITES netID)
  • If you need to connect to your ITG ctdata directory: smb://files.itg.beckman.illinois.edu/ctdata/netID (replace netID with your CITES netID)
  • Username: uofi\netID (replace netID with your CITES netID)
  • Password: your CITES AD password

Using a Linux machine?

There are at least two ways to connect to Windows shares on Linux. The most common way is to use the grafical (GUI) interface, as shown on this website: http://www.howtogeek.com/howto/29167/3-easy-ways-to-connect-to-windows-shared-folders-from-linux/. This method is flawed because you only have access to files through the GUI window, you do not have command line (hard mount) access to your files. Certain programs like Matlab and Amira require command line (hard mount) access to files. The better method of connecting to your Windows share is to use the /sbin/mount.cifs command. Here's how:

  • Open a terminal window. (Application menu -> System Tools -> Terminal)
  • Create the mount point:
    • mkdir /home/[yournetID]/windows-share
  • Mount the Windows share:
    • sudo /sbin/mount.cifs //files.itg.beckman.illinois.edu/users/[yournetID] /home/[yournetID]/windows-share -o username=[yournetID],domain=uofi,file_mode=0777,dir_mode=0777
  • It will prompt you for your CITES AD password. (should be the same password you use to login to the ITG computers)
  • Unmount the Windows share before logoff:
    • sudo umount /home/[yournetID]/windows-share
  • You can connect to other servers as well, such as bi-files:
    • sudo /sbin/mount.cifs //bi-files.beckman.illinois.edu/[sharename] /home/[yournetID]/windows-share-2 -o username=[yournetID],domain=uofi,file_mode=0777,dir_mode=0777
  • All ITG systems have the proper mount.cifs commands installed, and users are given sudo access to run mount.cifs. If your are trying to mount Windows shares (via mount.cifs) on a non-ITG Linux machine, you will have to ask your sysadmin to install the proper mout.cifs command as well as give you sudo access to run that command.
  • The instructions above are known to work on a RHEL6 install. Other RedHat Linux levels, and other flavors of Linux, may not work the same exact way. But all OS's should have some root level access to hard mount Windows shares.

QUICK INSTRUCTIONS:

Don't forget the uofi\ in front of your netID, without the uofi\ the connection will fail.<

CTData and Groups folders are given by request only
