Details

The rsh package contains the client commands for the rsh services.

*Rationale*

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.

Solution

Uninstall the rsh-client and rsh-reload-client packages-# apt-get purge rsh-client rsh-reload-client
