rsh is enable, so rsh reboot hostname or rsh /usr/sbin/shutdown -r now will work.
What I need is to reboot multiple hosts and read from a file that contain name of hosts.
FOR or WHILE loop is ok.
Thanks
rsh actually dont use secure channels.
(maybe with -x provides activate des about just input and output stream.
(like username, but already is not used because of probably you save to user credentials to .rhosts) .
some variants also does not support this also..
if you still want rsh , you can use this command if you start in.rshd in remote machines.
but you must certainly use ssh instead of rsh if security is important.

rsh
RSH(1) BSD General Commands Manual RSH(1)NAME
rsh -- remote shell
SYNOPSIS
rsh [-Kdnx] [-l username] host [command]
DESCRIPTION
Rsh executes command on host.
Rsh copies its standard input to the remote command, the standard output of the remote command to its standard output, and the standard error
of the remote command to its standard error. Interrupt, quit and terminate signals are propagated to the remote command; rsh normally termi-
nates when the remote command does. The options are as follows:
-d The -d option turns on socket debugging (using setsockopt(2)) on the TCP sockets used for communication with the remote host.
-l By default, the remote username is the same as the local username. The -l option allows the remote name to be specified.
-n The -n option redirects input from the special device /dev/null (see the BUGS section of this manual page).
If no command is specified, you will be logged in on the remote host using rlogin(1).
Shell metacharacters which are not quoted are interpreted on local machine, while quoted metacharacters are interpreted on the remote
machine. For example, the command
rsh otherhost cat remotefile >> localfile
appends the remote file remotefile to the local file localfile, while
rsh otherhost cat remotefile ">>" other_remotefile
appends remotefile to other_remotefile.
FILES
/etc/hosts
SEE ALSO rlogin(1),
HISTORY
The rsh command appeared in 4.2BSD.
BUGS
If you are using csh(1) and put a rsh in the background without redirecting its input away from the terminal, it will block even if no reads
are posted by the remote command. If no input is desired you should redirect the input of rsh to /dev/null using the -n option.
You cannot run an interactive command (like rogue(6) or vi(1)) using rsh; use rlogin(1) instead.
Stop signals stop the local rsh process only; this is arguably wrong, but currently hard to fix for reasons too complicated to explain here.
