You can ssh directly to the RTDC machines from CF.

$ ssh rtdc9

SSH from RTDC to CF

You must first ssh to login (the CF will have given you a password to this login machine), and from there ssh to one of the CF machines.

$ ssh login
$ ssh cfa0

Transferring data between CF and RTDC

To transfer data between the CF and RTDC you should always start at the CF location and push or pull accordingly. This avoids the login gateway.

• E.g. Transfer 'myfiles' in your current working directory on the CF to rtdc7:

  $ scp myfiles user@rtdc7:/home/user

• E.g. Transfer 'myfiles' from your home directory on rtdc7 to your current working directory on the CF:

  $ scp user@rtdc7:/home/user/myfiles .
  

If you have a very large file, you may find rsyncing more reliable than scp. Beware you do not overwrite your new version with the old.

• Transfer data from your current working directory on cfa0 to rtdc9:

  $ rsync -av myfile.tar user@rtdc9:/reduction/user

Using rsync is particularly efficient if a version of the file already exists at the destination, as it will only transfer the differences. On the first occasion though it will transfer over the full file.


Transfer data between different RTDC machines

Data can be transferred between the RTDC machines using scp, however the bigger reduction spaces are mounted on most machines. Find details at Disk names and mount points.
