Accessing clusters and data transfer

Information

  • Access (login) to PLGrid machines and file transfer is done through secure connections, using the SSH protocol. This protocol is used for encrypted connections, allowing remote work on another server in the network.
  • To log in to the PLGrid server, you should use an SSH client. There are many free SSH clients available, working on most operating systems. Among them, you can mention programs like ssh and slogin for Unix/Linux systems, and MobaXterm for Windows systems.
  • The password for logging in is the same as your user account password in the PLGrid Portal.

Logging in

To log in to a cluster, such as Ares (ares.cyfronet.pl):

Linux

ssh <login>@ares.cyfronet.pl

Windows

If you are using a Windows-based system, useful programs include PuTTY and MobaXterm (documentation for MobaXterm is available on the manufacturer's website: MobaXterm Documentation).

File transfer

Linux

For copying files, we recommend using secure copy programs such as scp or rsync. For Windows systems, you can use WinSCP.

Sample commands scp:

Copy the file to the access server ares.cyfronet.pl

scp file <login>@ares.cyfronet.pl:~

Copy the file from the access server ares.cyfronet.pl to the local machine's current directory

scp <login>@ares.cyfronet.pl:file .

Copy the entire directory folder to the access server ares.cyfronet.pl with compression enabled

scp -C -r folder <login>@ares.cyfronet.pl:~

Copy the entire directory folder from the access server ares.cyfronet.pl with compression enabled to the local machine's current directory

scp -C -r <login>@ares.cyfronet.pl:folder .

Windows

WinSCP – a graphical SFTP client for MS Windows using SSH.
