The talk software makes it possible for users to send and receive messages across systems through a terminal session. The talk client (allows initiate of talk sessions) is installed by default.
The software presents a security risk as it uses unencrypted protocols for communication.
Ensure the talk services are not enabled:
grep ^talk /etc/inetd.conf
grep ^ntalk /etc/inetd.conf
No results should be returned.
Remove or comment out any talk or ntalk lines in /etc/inetd.conf:
sed -i 's/^talk/#talk/' /etc/inetd.conf
sed -i 's/^ntalk/#ntalk/' /etc/inetd.conf
Not enabled by default on Ubuntu 12.04 LTS Server.
