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
Run the following command to remove rsh:
# yum erase rsh
Default Value:
OS Default: Not Installed
