How to use remote shell (rsh)

The rsh command is short for remote shell. This command starts a shell on the specified remote host and executes the command specified by the user in the rsh command line. If the user does not provide the command to be executed, RSH uses the rlogin command to log on to the remote machine. The general format of the rsh command is: RSH [-kdnx] [-K realm] [-l username] host [command]. The common format is: rsh host [command] command can be any Linux Command from the shell prompt. The meaning of each option in the rsh command is as follows:-K closes all the o validation. This option is used only when it is connected to the host confirmed by using the o. -D open the socket debugging of TCP sockets that communicates with the remote host. For more information, see the online help of setsockopt. -K requests rsh to obtain the Kerberos permission for the remote host in the specified region, instead of obtaining the Kerberos permission for the remote host in the remote host region determined by krb_relmofhost (3. -L by default, the remote user name is the same as the local user name. This option allows you to specify a remote user name. If you specify a remote user name, use Kerberos to confirm, as in the rlogin command. -N redirects the input from the special device/dev/null. -X enables DES encryption for all transmitted data. This affects response time and CPU utilization, but improves security. Linux puts the standard input into the rsh command and copies it to the standard input of the command to be remotely executed. It copies the standard output of remote commands to the standard output of RSH. It also copies remote standard errors to the local standard error file. All exit, stop, and interrupt signals are sent to remote commands. When the remote command is terminated, RSH is terminated.
