RSH(1) RSH(1)
NAME
rsh - remote shell
SYNOPSIS
rsh host [-l username] [-n] [-d] [-k realm] [-f | -F] [-x] [-PN | -PO] command
DESCRIPTION
Rsh connects to the specified host, and executes the specified command. 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 stan-
dard error. This implementation of rsh will accept any port for the standard error
stream. Interrupt, quit and terminate signals are propagated to the remote com-
mand; rsh normally terminates when the remote command does.
Each user may have a private authorization list in a file .k5login in his login
directory. Each line in this file should contain a Kerberos principal name of the
form principal/instance@realm. If there is a ~/.k5login file, then access is
granted to the account if and only if the originater user is authenticated to one
of the princiapls named in the ~/.k5login file. Otherwise, the originating user
will be granted access to the account if and only if the authenticated principal
name of the user can be mapped to the local account name using the aname -> lname
mapping rules (see krb5_anadd(8) for more details).
OPTIONS
-l username
sets the remote username to username. Otherwise, the remote username will
be the same as the local username.
-x causes the network session traffic to be encrypted. This applies only to
the input and output streams, and not the command line.
-f cause nonforwardable Kerberos credentials to be forwarded to the remote
machine for use by the specified command. They will be removed when command
finishes. This option is mutually exclusive with the -F option.
-F cause forwardable Kerberos credentials to be forwarded to the remote machine
for use by the specified command. They will be removed when command fin-
ishes. This option is mutually exclusive with the -f option.
-k realm
causes rsh to obtain tickets for the remote host in realm instead of the
remote host’s realm as determined by krb_realmofhost(3).
-d turns on socket debugging (via setsockopt(2)) on the TCP sockets used for
communication with the remote host.
-n redirects input from the special device /dev/null (see the BUGS section
below).
-PN
-PO Explicitly request new or old version of the Kerberos ‘‘rcmd’’ protocol.
The new protocol avoids many security problems found in the old one, but is
not interoperable with older servers. (An "input/output error" and a closed
connection is the most likely result of attempting this combination.) If
neither option is specified, some simple heuristics are used to guess which
to try.
If you omit command, then instead of executing a single command, you will be logged
in on the remote host using rlogin(1).
Shell metacharacters which are not quoted are interpreted on the local machine,
while quoted metacharacters are interpreted on the remote machine. Thus the com-
mand
rsh otherhost cat remotefile >> localfile
appends the remote file remotefile to the local file localfile, while
rsh otherhost cat remotefile ">>" otherremotefile
appends remotefile to otherremotefile.
FILES
/etc/hosts
~/.k5login (on remote host) - file containing Kerberos principals that are allowed
access.

BUGS
If you are using csh(1) and put a rsh(1) 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)); use rlogin(1).
Stop signals stop the local rsh process only; this is arguably wrong, but currently
hard to fix for reasons too complicated to explain here.
