 Once authorised, one could access the cluster via ssh protocol. The required password is the one of your university e-mail. From the Linux terminal, type the following instruction:
-  * if you are a **student** or a **staff member**: ''ssh name.surname00@137.204.50.177''
+  ssh name.surname00@137.204.165.41
+(you can use any other ophfeX address instead of 137.204.165.41)
-Once logged-in, you will be landed on the [[oph:cluster:jobs|Frontend]], the workspace shared by all users that is employed to submit jobs and access datasets stored in memory.

 **Please pay attention to this policy**: the stable number of files saved in /scratch shall not exceed a few thousand per user. Otherwise, the system becomes incredibly slow and unstable. Periodic checks on the number of files of each user are carried out automatically.
+**Note to student supervisors **: Once you have created the data write folder for your students, you can request read and write rights to access the files through ''setfacl -m u:name.surname0:rw /home/pathToFolder'', where ''name.surname0'' is your account name and ''/home/pathToFolder'' is the universal path to the folder you want to access.

 The submission of a job is done via a bash-type script, consisting of: the header with metadata for users, the execution settings (e.g. number of processors, memory, execution time), the modules and the executable to be run. See the section [[oph:cluster:jobs|Run a Job]] for more details.
