Check the firewall configuration for any unnecessary or prohibited
functions, ports, protocols, and/or services by running the following
command:
$ sudo ufw show raw
Chain OUTPUT (policy ACCEPT)
target prot opt sources destination
Chain INPUT (policy ACCEPT 1 packets, 40 bytes)
pkts bytes target prot opt in out source destination
Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)
pkts bytes target prot opt in out source destination
Chain OUTPUT (policy ACCEPT 0 packets, 0 bytes)
pkts bytes target prot opt in out source destination
Ask the System Administrator for the site or program PPSM CLSA. Verify
the services allowed by the firewall match the PPSM CLSA.
