uninstall-talk

The talk program allowed users on early unix systems in the 80’s and 90’s to chat with each other. As it does not encrypt communication, and has been proven vulnerable in several ways, its use today is discouraged.

Recommendation: Do not use talk as it is insecure (provides no encryption for communication). Uninstall both talk and talk-server, and ensure it isn’t used / installed in your infrastructure. This module provides an easy way to achieve this.

Example

If you try installing the package(s) and running the agent with this module, you should see it get uninstalled:

$ apt install talk
$ cf-agent -KI
    info: Successfully removed package 'talk'

Adding exceptions

If this package is really needed on some hosts, you can add an exception with the exception_uninstall_talk class. This class can be set within def.json (Augments), from policy, or in the Host specific data section in host info pages inside Mission Portal, the CFEngine Enterprise Web UI.
