Configuring rsh or remsh
The rsh (remote shell) program lets you log on to and execute commands on a
remote system. The remote system on which the rsh executes the command
must be running the rsh daemon.
The rsh program is not secure for network use, because it sends unencrypted
information over the network. The ssh program is the preferred method of
remote communication because it is more secure than the rsh suite of protocols.
See “ Configuring ssh ” on page 26.
If you run rsh with the basename “remsh,” rsh checks for the file
/usr/bin/remsh
. If this file exists, rsh uses remsh is an alias for rsh. If
/usr/bin/remsh
does not exist, rsh uses remsh as a host name.
Before you enable rsh, read the rsh documentation and online manual pages. If
you have questions or issues about your rsh configuration, see the operating
system documentation.
