Transfering files to / from Notur systems

All Notur systems are stand-alone systems, and in general we do not (NFS-)mount remote disks on them. Therefore you must either explicitly transfer any files you wish to use by using either sftp or scp, or you can mount your home directory('s) on the Notur systems on you own computer.

Transfering files to/ from a Notur system using Linux:

If you are working on a Linux/Unix machine, files can be transferred securely to/from a Notur system with sftp (similar to old ftp) or scp. See the man pages, 'man sftp' and 'man scp', for complete lists of interactive commands within sftp and scp.

If you have an ssh client installed on you machine, you most probably have an sftp client too. Check out the OpenSSH page for more information about ssh and sftp for your system.

Example1; uploading a file on snykov.uit.no with sftp:

[donald@my-pc ~]$ sftp snykov.uit.np
Connecting to snykov.uit.np...
donald@snykov.uit.no's password:
sftp> put test.f
Uploading test.f to /home/donald/test.f
test.f                                                        100%  201     0.2KB/s   00:00
sftp> bye
[donald@my-pc ~]$

Downloading: replace put with get.

Example2; downloading multiple files on snykov.uit.no with sftp:

If you want to dowload / upload multiple files, replace put and get with mput and mget. For instance if you have a bunch of Fortran files you want to move from Snykov to you own computer:

[donald@my-pc ~]$ sftp snykov.uit.no
Connecting to snykov.uit.no...
donald@snykov.uit.no's password:
sftp> mget *.f
Fetching /home/donald/pass.f to test1.f
/home/donald/test1.f                                          100%  146     0.1KB/s   00:00
Fetching /home/donald/test.f to test2.f
/home/donald/test2.f                                          100%  201     0.2KB/s   00:00
sftp> bye
[donald@my-pc ~]$

Uploading: replace mget with mput. To learn more about sftp please take a look at the man page; 'man sftp'.

Example3; uploading a file on snykov.uit.no with scp:

[donald@my-pc ~]$ scp file.txt donald@snowstorm.uit.no:
donald@snykov.uit.no's password:
test.f                                                        100%  201     0.2KB/s   00:00
[donald@my-pc ~]$

Example4; downloading multiple files from snykov.uit.no with scp:

[donald@my-pc ~]$ scp donald@snykov.uit.no:*.f .
donald@snykov.uit.no's password:
test1.f                                                       100%  146     0.1KB/s   00:00
test2.f                                                       100%  201     0.2KB/s   00:00
[donald@my-pc ~]$

To learn more about scp please take a look at the man page; 'man scp'.

Transfering files to/ from a Notur system using Windows

If you are using a Windows based workstation, you can easily and safely transfer files to/ from you machine and any Notur system by using one the many SSH / FTP tools available. Below is a short example showing the usage of Secure SSH, which is a commercial SW product. There are several freely available SSH / FTP clients for Windows that offers a similar functionality, for instance Core FTP and WinSCP.

Example using Secure SSH.
1. You have to log in to Snowstorm with your user name and password. You will then be in your /home directory.
2. Click on the yellow folder icon on the top menu in your SSH Secure Shell window

3. You will then get a new window (SSH Secure File Transfer) looking something like this:

Then you can drag and drop files and folders from this window to for instance your My Documents folder in Windows, and the other way around.
