Discussion

This talk service is used to establish an interactive two-way communication link between two UNIX users. Unless required the talk service will be disabled to prevent attacks.

Check Content

From the command prompt, execute the following command: 
# grep "^talk[[:blank:]]" /etc/inetd.conf

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

Fix Text

In "/etc/inetd.conf", comment out the "talkd" entry by running command:
# chsubserver -r inetd -C /etc/inetd.conf -d -v 'talk' -p 'udp'

Restart inetd:
# refresh -s inetd
