|
.Sh SYNOPSIS
|
|
.Nm
|
|
.Op Fl 46Kdnx
|
|
.Op Fl t Ar timeout
|
|
.Op Fl k Ar realm
|
|
.Op Fl l Ar username
|

|

|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility executes
|
|
.Ar command
|
|
on
|
|
.Ar host .
|
|
.Pp
|
|
The
|
|
.Nm
|
|
utility 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;
|
|
.Nm
|
|
normally terminates when the remote command does.
|
|
The options are as follows:
|
|
.Bl -tag -width flag
|
|
.It Fl 4
|
|
Use IPv4 addresses only.
|
|
.It Fl 6
|
|
Use IPv6 addresses only.
|
|
.It Fl K
|
|
Turn off all Kerberos authentication.
|
|
.It Fl d
|
|
Turn on socket debugging (using
|
|
.Xr setsockopt 2 )
|
|
on the
|
|
.Tn TCP
|
|
sockets used for communication with the remote host.
|
|
.It Fl k Ar realm
|
|
Cause
|
|
.Nm
|
|
to obtain tickets for the remote host in
|
|
.Ar realm
|
|
instead of the remote host's realm as determined by
|
|
.Xr krb_realmofhost 3 .
|
|
.It Fl l Ar username
|
|
Allow the remote
|
|
.Ar username
|
|
to be specified.
|
|
By default, the remote username is the same as the local username.
|
|
Kerberos authentication is used, and authorization is determined
|
|
as in
|
|
.Xr rlogin 1 .
|
|
.It Fl n
|
|
Redirect input from the special device
|
|
.Pa /dev/null
|
|
(see the
|
|
.Sx BUGS
|
|
section of this manual page).
|
|
.It Fl x
|
|
Turn on
|
|
.Tn DES
|
|
encryption for all data exchange.
|
|
This may introduce a significant delay in response time.
|
|
.It Fl t Ar timeout
|
|
Allow a
|
|
.Ar timeout
|
|
to be specified (in seconds).
|
|
If no
|
|
data is sent or received in this time,
|
|
.Nm
|
|
will exit.
|
|
.El
|
|
.Pp
|
|
If no
|
|
.Ar command
|
|
is specified, you will be logged in on the remote host using
|
|
.Xr rlogin 1 .
|
|
.Pp
|
|
Shell metacharacters which are not quoted are interpreted on local machine,
|
|
while quoted metacharacters are interpreted on the remote machine.
|
|
For example, the command
|
|
.Pp
|
|
.Dl rsh otherhost cat remotefile >> localfile
|
|
.Pp
|
|
appends the remote file
|
|
.Ar remotefile
|
|
to the local file
|
|
.Ar localfile ,
|
|
while
|
|
.Pp
|
|
.Dl rsh otherhost cat remotefile \&">>\&" other_remotefile
|
|
.Pp
|
|
appends
|
|
.Ar remotefile
|
|
to
|
|
.Ar other_remotefile .
|
|
.\" .Pp
|
|
.\" Many sites specify a large number of host names as commands in the
|
|
.\" directory /usr/hosts.
|
|
.\" If this directory is included in your search path, you can use the
|
|
.\" shorthand ``host command'' for the longer form ``rsh host command''.

.Sh HISTORY
|
|
The
|
|
.Nm
|
|
command appeared in
|
|
.Bx 4.2 .
|
|
.Sh BUGS
|
|
If you are using
|
|
.Xr csh 1
|
|
and put a
|
|
.Nm
|
|
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
|
|
.Nm
|
|
to
|
|
.Pa /dev/null
|
|
using the
|
|
.Fl n
|
|
option.
|
|
.Pp
|
|
You cannot run an interactive command
|
|
(like
|
|
.Xr rogue 6
|
|
or
|
|
.Xr vi 1 )
|
|
using
|
|
.Nm ;
|
|
use
|
|
.Xr rlogin 1
|
|
instead.
|
|
.Pp
|
|
Stop signals stop the local
|
|
.Nm
|
|
process only; this is arguably wrong, but currently hard to fix for reasons
|
|
too complicated to explain here.
