Introduction

1. Data generated by the spectrometers is available for download via SFTP. The data on the SFTP server is refreshed about every 10 minutes.   The test for copying the file is that its modification date is in the period since the last mirroring. 

   Some files will not then be mirrored -- e.g. tar restores with original creation times.  Users may need to 'touch' these files to update them.  Files deleted on the spectrometer are not deleted on the mirror.  However, there is no version control, and overwriting a previous file will result in loss of the original data on the mirror.

2. You should be able to read data associated with your own user id, or the group id's you made readable on the original spectrometer computer. Your username and password will be the same as the username / password used to log on to the spectrometers.

3. The system will be unavailable for maintenance every Monday between 10 am and 2pm.  The system may appear to be on-line during this period, but attempted transfers may fail.

4. We will make every effort to ensure that data is available on the mirror for 60 days or more. 

   There is presently no provision for any regular restoration of data beyond 60 days.

5. For the spectrometer computers, we appreciate the need to preserve the small setup files, and the procedure will be to move 'large' (yet to be defined) files to ,[filename] at later than 60 days from original creation, and for these to be deleted 14 days later.

6. Your login directories will now be in the xwinnmr data space in the spectrometer computers. 

   Any old data in /home/[loginname] will be moved.

7. The use of the old institutional logins is deprecated, The institutional logins will have the same user id number as the principal institutional user.  That user can then remove, rename, etc. these files. The principal institutional user will be the NMR committee representative, unless we are otherwise informed.   We recommend that this user make the files group-readable, if there are multiple users associated with the old account.

8. The recommended method for transferring files between spectrometers is to do so using the mirrored files on the sftp server.   For security reasons, direct sftp between spectrometer computers will no longer be available.  The use of the mirror should be entirely effective, with the caveat that data may be upto 10 minutes out of date.

10. Please address issues about NMR files on the spectrometers to Dr. Bhattacharya at:

11. Please address comments about the overall operation or suggestions for additional features to Dr. Goger or Dr. Cowburn.

Client Software

1. SFTP can be run from the command line but this method has some limitations. To be able to transfer multiple files or directories, client software is needed.

   1. SSH Secure Shell for Workstations
      Compatible client with both Windows and Unix is available at
      http://www.ssh.com/support/downloads/secureshellwks/non-commercial.html. Unix versions may require complilation.

   2. GFTP
      GFTP is a compatible client for Linux systems available on Linux 7.2 and higher. It can be downloaded from http://gftp.org. To access the NYSBC SFTP Server Version 2.0.9 or higher is needed.

2. Connecting To The SFTP Server

   1. Using Windows GUI with SSH shell Type in Host Name and your User Name. Leave all other settings the same, as shown in figure 1
      
      Figure 1
      
      

      
      
      
      
      
      
      
      
      
      

   2. Enter Password at password screen

   3. Change to the /nysbc_nmr directory to view a list of spectrometers.
      
      Figure 3
      
      
      
      
      
      
      
      
      
      
      
      
      
      
      
      
      
      
      
      
      
      
      
      
      
      
      
      
      
      
      
      
      
      
      
      

   4. Change to your appropriate directory and transfer files using drag and drop or select, right click, and download.

3. Using SFTP2

   1. Type sftp2 <username>@sftp.nysbc.net into a terminal window, enter password when prompted.

   2. Change directory to /nysbc_nmr.

   3. Spectrometers are listed in the /nysbc_nmr directory.
