The rsh-client package contains the client commands for the rsh services.
These legacy clients contain numerous security exposures and have been replaced with the more secure SSH package. Even if the server is removed, it is best to ensure the clients are also removed to prevent users from inadvertently attempting to use these commands and therefore exposing their credentials. Note that removing the rsh package removes the clients for rsh, rcp and rlogin.
Run the following command to verify rsh-client is not installed:
# dpkg-query -W -f='${binary:Package}\t${Status}\t${db:Status-Status}\n' rsh-client
Verify rsh-client is not installed.
rsh-client package should not be installed.
Run the following command to remove rsh-client:
# apt purge rsh-client
rsh-client is not installed by default.
