6. Qual aplicação pode ser usada no lugar do xhost? Por favor, indique apenas o nome, sem caminho.

Xhost is a command that allows users to grant access to their X server for other users. However, it is considered insecure as it allows any user to connect to the X server. Xauth, on the other hand, is a more secure alternative. It is a command that manages X authority files, which are used to authenticate connections to the X server. By using xauth, users can selectively grant access to their X server, providing a more secure environment.
