Details
Check Text (C-268131r1039281_chk)
Ensure the telnet package is not installed and available with the following command:
$ whereis telnet
telnet:
If there is a path, and the output looks like "telnet: /nix/store/sqiphymcpky1yysgdc1aj4lr9jg9n53a-inetutils-2.2/bin/telnet", this is a finding.
Fix Text (F-71958r1039280_fix)
Edit the NixOS Configuration file with "nano /etc/nixos/configuration.nix" and remove any references to pkgs.libtelnet, pkgs.busybox, or pkgs.inetutils from the environment.systemPackages list.
Rebuild the NixOS configuration with the following command:
$ sudo nixos-rebuild switch
