I cannot think of any way to do this within the Slurm configuration I would solve this by having a wrapper run at boot time which started a new sshd process on a different port which you secured (ie only that user could connect) and then start this as part of your boot time scripts If your script was started on one of your ‘special’ machines, start the second instance of sshd…..if not, do nothing

I believe a system admin has set up a PAM module that does the block. Whn trying ssh, this is the message returned: Access denied by pam_slurm_adopt: you have no active jobs on this node Connection closed by 10.135.242.188 port 22 However, we would like to allow sftp on a specific compute node for specific users. Any idea on how to do that? Thanks, Fritz Ratnasamy Data Scientist Information Technology The University of Chicago Booth School of Business 5807 S.
