RLOGIN(1N)              COMMAND REFERENCE              RLOGIN(1N)



NAME
     rlogin - remote login

SYNOPSIS
     rlogin rhostname[ -ec ] [ -l username ] [ -8 ]
     rhostname[ -ec ] [ -l username ] [ -8 ]

DESCRIPTION
     Rlogin connects your terminal on the current local host
     system to the remote host, rhostname.

     Each host has a file /etc/hosts.equiv (see hosts.equiv(5n))
     which contains a list of host names which are 'trusted'
     enough that their users are allowed to run programs on the
     local system (see rsh(1n)), copy files between the local and
     remote sytems (see rcp(1n)), and login to the local system,
     all without the use of passwords.  Each user may also have a
     private equivalence list in a file .rhosts in his or her
     login directory. Each line in this file should contain a
     rhost and a username separated by a space, giving additional
     cases where logins without passwords are to be permitted.
     If the originating user is not not listed in
     /etc/hosts.equiv or the appropriate .rhosts file, then a
     login and password will be prompted for on the remote
     machine as in login(1).  To avoid some security problems,
     the .rhosts file must be owned by either the remote user or
     root and may not be a symbolic link.

     If there is no home directory for the user on the remote
     system, rlogin will print Sorry, home directory required and
     prompt for another login.

     The second form of invoking rlogin, where you omit the
     "rlogin" is possible if you place in some directory in your
     search path a symbolic link (see ln(1)) linking rhostname to
     /bin/rsh.  This works because rsh can inspect its
     invocation, and if it finds only a hostname, rsh assumes you
     want to login in.

     Your remote terminal type is the same as your local terminal
     type (as given in your environment TERM variable).  All
     echoing takes place at the remote site, so that (except for
     delays) the rlogin is transparent.  Flow control, via
     <CTRL-S> and <CTRL-Q> and flushing of input and output on
     interrupts, are handled properly.  A line of the form

          <RETURN> <TILDE> <DOT> <RETURN>

     disconnects from the remote host, where tilde (~) is the
     escape character.  A different escape character may be
     specified by the -e option.

RLOGIN(1N)              COMMAND REFERENCE              RLOGIN(1N)



     If you are a csh(1) user, you can suspend a remote login by
     either

          <RETURN> <TILDE> <CTRL-Z> <RETURN>
                    or

          <RETURN> <TILDE> <CTRL-Y> <RETURN>

     The former will stop all output until you bring the rlogin
     job back into the foreground, the latter will not.  However,
     if you want the output from a suspended rlogin (or any other
     suspended job, for that matter) not to be held up, you must
     also turn off the stty(1) option tostop, i.e. stty -tostop.
     Typically you would place that stty option in your .login.

     Note that you can have a whole chain of rlogin's and
     selectively suspend to any previous one.  Suppose you logged
     into machine able, and from there rlogin'd to baker, and
     from there you rlogin'd to charlie.  If you currently are on
     charlie and want to suspend that job and return to able, you
     could type

          <RETURN> <TILDE> <CTRL-Z> <RETURN>.

     You could also elect to suspend your charlie rlogin and
     return to baker by typing

          <RETURN> <TILDE> <TILDE> <CTRL-Z> <RETURN>.

     Having said this it should be noted that it is much more
     efficient to rlogin direct to a host, rather than set up a
     chain of rlogins.

OPTIONS
     -ec Set the escape character to be the c character.  There
         is no space separating this option flag and the argument
         character.

     -l username
         Specify the login username to login as on the remote
         host.

     -8  Set rlogin to transparently handle 8-bit characters.
         You lose flow control with this option (cntl-S and
         cntrl-Q) but you gain the ability to transfer 8-bit
         data.  Typically this would be useful if your terminal
         sends 8 bit graphical data in response to some command
         from the host.

EXAMPLES
     This example illustrates how to rlogin to another user's
     account (in this case, sheryl's) on remote host engr1:

RLOGIN(1N)              COMMAND REFERENCE              RLOGIN(1N)




          rlogin engr1 -l sheryl

     If there was an entry in the .rhosts file in sheryl's home
     directory for the user attempting the rlogin, then no
     password would be required.

FILES
     /usr/hosts/*             For rhost version of the command.

RETURN VALUE
     [3]              Remote process has died, Connection is
                    closed.

     [USAGE]        Incorrect command line syntax. Execution
                    terminated.

     [NP_WARN]      An error warranting a warning message
                    occurred. Execution continues.

     [NP_ERR]       An error occurred that was not a system
                    error.  Execution terminated.

     [P_ERR]        A system error occurred. Execution
                    terminated.  See intro(2) for more
                    information on system errors.

     [P_WARN]       A system error occurred. Execution continues.
                    See intro(2) for more information on system
                    errors.

CAVEATS
     More terminal characteristics should be propagated.
