At IU, how do I map or mount my SDA account to my workstation?
Note: For information about other methods of accessing the SDA, see At IU, how do I access the SDA?
Samba servers act as a gateway between Indiana University's Scholarly Data Archive (SDA) servers and your workstation, and provide a fast and easily configured way of accessing your SDA files and folders. See the appropriate section below for instructions on mapping or mounting your SDA account to your workstation.
Note: If you are connecting from outside the IU network, your computer must be configured to use VPN. For help, see The basics of VPN at IU.

Note: To use Samba to connect to the Research File System (RFS) or Scholarly Data Archive (SDA) from a Windows computer that is not joined to the Indiana University ADS domain, you may need to run a tool that disables LM/NTLMv1. See What is the tool that disables LM/NTLMv1, and where can I get it?
The Samba interface allows you to access your SDA files and folders as if they resided on a drive on your workstation. Before you can access your SDA folder directly, you need to configure your computer as follows:
My Computerand select
Map Network Drive....
- In the "Folder:" field, type the path for your SDA account:
usernamewith your username and click
- You will be prompted to enter a username and password. Your SDA folder will be mapped to a drive on the workstation.
Mac OS X
To access your SDA account using Samba:
- In the Finder, from the
Connect to Server....
- In the
Connect to Serverwindow, in the "Server Address:" field, type: smb://smb.mdss.iu.edu/username
usernamewith your username. Click
- You will be asked to authenticate. Type your username and password
in the appropriate boxes. Click
- Your SDA folder will be mounted shortly.
To establish file system access to the SDA from Linux via Samba,
use one of the following methods (replace
your IU Network ID; you will be prompted for your
- Mount SDA as
rooton the local machine, as follows: # mkdir /mdss # mount.cifs //smb.mdss.iu.edu/netid /mdss -o user="netid",uid="localuserid",sec=ntlmv2,domain=ads
Note that the
localuseridis a username or UID of a non-root user on the machine that will need permission to view the SDA account. The
uid=localuseridmay be omitted if the local account has the same UID as your Network ID. Another option,
gid=localgidwill likewise map the SDA group ID to a group ID on your machine.
- Once you are finished, you can disconnect using the following command: # umount /mdss
- If you do not have local root access, you can use the following commands:
> mkdir ~/mdss
> mount.cifs //smb.mdss.iu.edu/netid ~/mdss -o user="netid",uid="localuserid",sec=ntlmv2,domain=ads
mount.cifsdoes not work without root access, contact your system administrator.
- Once you are finished with a user-mounted connection, you can disconnect using the following command: > umount.cifs ~/mdss
Other SDA shares
SDA serves out several Samba/CIFS shares to control the class of service (COS) into which data is uploaded and to provide the ability to navigate to other users' shared folders. To use any of the following, substitute the name of the share for your username in the examples above:
small: This maps to COS 1, which is for small
files (up to 4 MB).
medium: This maps to COS 2, which is for
medium-sized files (from 4 MB to 64 MB).
large: This maps to COS 3, which is for large
files (from 64 MB to 1 TB).
hpss-home: This maps to the top-level directory
in SDA, where you can traverse the directory tree to the home
directory of another user. For example, the username
usernamewould be under directory
s, and then
username. Note that you won't be able to view the files unless the user has set permissions for you to do so.
