Discussion

"autoconf6" is used to automatically configure IPv6 interfaces at boot time. Running this service may allow other hosts on the same physical subnet to connect via IPv6, even when the network does not support it. Disable this unless you use IPv6 on the server.

Check Content

From the command prompt, execute the following command: 
# grep "^start[[:blank:]]/usr/sbin/autoconf6" /etc/rc.tcpip

If there is any output from the command, this is a finding.

Fix Text

In "/etc/rc.tcpip", comment out the "autoconf6" entry by running command: 
# chrctcp -d autoconf6
