QUESTION 14
Click the Exhibit button.
A system on your network is named sys-01. This system has Solaris 10 OS with packet filtering enabled and configured. The Solaris IP Filter configuration, stored in the /etc/ipf/ipf.conf file of this system was: pass in quick proto tcp from any to any port = 22 keep state block in all and allowed an ssh connection into your sys-01 system from both hme0 and hme1 interfaces. Due to a change in your network, you had to modify the packet filtering rules of the sys-01 system. The packet filtering rules now allow ssh connections into sys-01 only using the hme0 interface. The following changes are made to /etc/ipf/ipf.conf: pass in quick on hme0 proto tcp from any to 192.168.1.1/32 port = 22 keep state block in all
Which command loads the new packet filtering rules?
