This entry starts the talkd daemon when required. This service establishes a two-way communication link between two users, either locally or remotely. This talk service is used to establish an interactive two-way communication link between two UNIX users. It is unlikely that there would be a requirement to run this type of service on a UNIX system. Unless required the talk service will be disabled
Solution
In /etc/inetd.conf, comment out the talk entry- chsubserver -r inetd -C /etc/inetd.conf -d -v 'talk' -p 'udp'
