ALL:ALL@<Management Server private IP address>
By uncommenting these lines, all users from the Management Server will be denied access. There is also
a /etc/hosts.allow file that explicitly permits access to some users. It is configured, by default, to allow ac
to root and lsfadmin:
ALL:root@ALL
ALL:lsfadmin@ALL
Although the hosts.deny file disallows all access, the entries in hosts.allow override the settings of
hosts.deny. The hosts.deny file also does not prevent users from accessing telnet and remsh between
Compute Nodes. This allows MPI-based applications to run when submitted to a ClusterWare Pro™ queu
More information about the settings in hosts.deny and hosts.allow can be found in the man pages:
