Title

If DHCP is not enabled in the network on AIX, the dhcprd daemon must be disabled. (Cat II impact)

Discussion

The dhcprd daemon listens for broadcast packets, receives them, and forwards them to the appropriate server. To prevent remote attacks this daemon should not be enabled unless there is no alternative.

Check Content

From the command prompt, execute the following command: # grep "^start[[:blank:]]/usr/sbin/dhcprd" /etc/rc.tcpip If there is any output from the command, this is a finding.

Fix Text

In "/etc/rc.tcpip", comment out the "dhcprd" entry by running command: # chrctcp -d dhcprd
