However, I've never had issues with it working. You'll also probably want to add LOCAL to the host field of the allow rule so that cron will be able to su. Alternatively, until you can get access.conf working, you could use AllowUsers and AllowGroups in sshd_config: AllowUsers root myusername AllowGroups root mygroup -- Gabe Turner gabe@xxxxxxxxxxx UNIX Systems Administrator, University of Minnesota Supercomputing Institute for Digital Simulation and Advanced Computation www.msi.umn.edu -- Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
