Logging from UNIX/Linux systems

UNIX/Linux systems usually have programs allowing to connect via SSH, such as slogin, ssh and scp (for copying files). To log in you can simply use command:

ssh <login>@<accesing_machine>

or

ssh -l <login> <accessing_machine> 

qhere <login> is the name of user account on the machine, and <accessing_machine> is the name of accessing machine or it's IP address. Eg. user with account kowalski can log on zeus.cyfronet.pl machine using command:

ssh kowalski@zeus.cyfronet.pl

Then user will be asked to enter password, and after that user can start working.

Working in graphical mode

If SSH connection should forward graphical user interface (XWindow) ssh command should be invoked with -Y flag:

ssh -Y <login>@<accessing_machine>

Caution: When using graphical interface remember to use -X while creating interactive job qsub -I -X.
