+## Connect on nodes during batch jobs
+
+Direct connection to compute nodes is forbidden in the Pyrene cluster. The only way to access resources allocated to a job is to submit another job. To do this, use the `srun` command to connect inside the targeted job. Assuming you have submitted a _job_id_ batch job:
+```
+$ sbatch script.sh
+Submitted batch job job_id
+```
+simply use the _job_id_ allocated by Slurm to connect to the corresponding node:
+```
+$ srun --pty --jobid job_id /bin/bash -i
+```
