Indiana University’s Research File System

What is the IU Research File System? /user1/user2 /collaboration User 1, on campus User 2, somewhere else BACKUP

RFS Access – Samba/CIFS

RFS Access - SFTP

RFS Access - Web

RFS Access – AFS Client

Works with all major operating systems: Mac, Windows and Linux/Unix RFS Access From an off-campus location, IU VPN is required for: – Samba – AFS client However, VPN is not needed for: – Web access ( – SFTP IU VPN introduction:

Right and wrong ways to use RFS Good Uses: relatively small files (up to ca. 1 GB in size) files that are updated frequently –remember that files can be edited directly in RFS, using Samba or the AFS client frequently accessed files files that need to be shared, i.e. group project work In short, treat RFS like a local hard drive, or a shared drive

Right and wrong ways to use RFS Poor Uses: backups –RFS is intended as workspace, use SDA for backups and archiving files updated by multiple users at once –for example, Access and other databases –files that many users edit simultaneously SDA introduction:

Policies storage quota for individual users is 100 GB; additional space may be available upon request RFS is available to faculty, staff and graduate students; undergraduates can be sponsored by faculty or staff data are backed up nightly, backups kept for 2 months you can request restoration of accidentally lost data changes from the previous day: –kept in the 1day-backup directory –you can restore data from 1day-backup yourself RFS storage system is HIPAA aligned

Collaborative work  You can request project space, distinct from your own user space  Initial quota for project spaces is 100 GB  You can define your own groups of RFS users  no shared accounts are required

Exercises

What we will do next: We will set up and try out every method of RFS access We will move files around We will open and edit files in RFS We will recover files from the one-day backup We will share files by using a project space We will regulate access to project files

Exercises - Samba Windows: Right-click My Computer → Map Network Drive.... \\rfs.iu.edu\username Macintosh: In the Finder, Go menu → Connect to Server.... smb://rfs.iu.edu/username

Exercises - SFTP Windows: Install WinSCP from Connect to rfs.iu.edu with your username … Macintosh: Install AnyClient from Connect to rfs.iu.edu with your username … For the brave: open the Terminal window instead, type: sftp and look here for sftp commands:

Exercises - Web Open the browser of your choice, go to Log in with your username …

Exercises – OpenAFS Client Install the Kerberos client Windows: Download and run the installer: kfw-.exe Choose to install KFW Client and KFW Documentation … For configuration files, enter: Macintosh: Your Mac should have the Kerberos client already installed.

Exercises – OpenAFS Client Obtain OpenAFS here: Windows: Download and run either one of these installers: OpenAFSforWindows-.exe openafs-en_US-.msi Choose to install OpenAFS client … Macintosh: Download and run the appropriate version of installer: OpenAFS dmg Click appropriate icon to install OpenAFS client …

Exercises – Projects \\afs\iu.edu\home\projects\UITS\RTSTOR\rfsclass group rfsclass_admin user rfsclass group rfsclass_user all of us r, l, d, i, w, k, ar, l, d, i, w, k r - read l - look up d - delete i - insert w - write k - lock a - administer

Exercises – Projects Please form teams of 3-5 people; each team should have at least one Windows user – nominate him/her as the project administrator. Create a team folder in the rfsclass project space. Check the folder’s Access Control List (ACL) Try changing the settings.

Exercises – Projects Administrator: Delete your credentials, then log back in as user rfsclass; Remove the permissions of the group rfsclass_user; Add r, l, d, i, w, k for every team member. Delete your administrative credentials, then log back in as yourself. All team members: Move some files in and out of your team’s folder; open each other’s files, modify them, delete them. Try opening the files in another team’s folder!
