[Qlustar-General] limit network access

Hej, I would like to limit access to the cluster via hosts.allow and hosts.deny. What is the best way to do it? I could create a script in /etc/qlustar/common/rc.boot/ that looks like this: #!/bin/bash echo 'sshd: ALL' >> /etc/hosts.deny echo 'sshd: localhost' >> /etc/hosts.allow echo 'sshd: xxx.xxx.xxx.xxx' >> /etc/hosts.allow Is that ok? Cheers, Iggy
