.Sh NAME
.Nm rlogin
.Nd remote login
.Sh SYNOPSIS
.Ar rlogin
.Op Fl 8EKLd
.Op Fl e Ar char
.Op Fl i Ar identity
.Op Fl l Ar username
.Op Fl p Ar port
.Ar host
.Sh DESCRIPTION
.Nm Rlogin
starts a terminal session on a remote host
.Ar host  .
.Pp
.Nm Rlogin
first attempts to use the Kerberos authorization mechanism, described below.
If the remote host does not supporting Kerberos the standard Berkeley
.Pa rhosts
authorization mechanism is used.
The options are as follows:
.Bl -tag -width flag
.It Fl 8
The
.Fl 8
option allows an eight-bit input data path at all times; otherwise
parity bits are stripped except when the remote side's stop and start
characters are other than
^S/^Q .
.It Fl i
The
.Fl i
option specifies the local user name to use for authentication with the remote
.Nm rlogind
server.  This overrides the default which is the name of the user invoking
.Nm rlogin .
.It Fl l
The
.Fl l
option specifies the name of the remote user to login as.  This overrides the
default which is the name of the user invoking
.Nm rlogin .
.It Fl E
The
.Fl E
option stops any character from being recognized as an escape character.
When used with the
.Fl 8
option, this provides a completely transparent connection.
.It Fl K
The
.Fl K
option turns off all Kerberos authentication.  This option has no effect since
Kerberos authentication is not available in this version.
.It Fl L
The
.Fl L
option allows the rlogin session to be run in ``litout'' (see
.Xr tty 4 )
mode.
.It Fl d
The
.Fl d
option turns on socket debugging (see
.Xr setsockopt 2 )
on the TCP sockets used for communication with the remote host.
.It Fl e
The
.Fl e
option allows user specification of the escape character, which is
``~'' by default.
This specification may be as a literal character, or as an octal
value in the form \ennn.
.It Fl p
The
.Fl p
option specifies the port to connect to.  This overrides the default
which is
.Nm login .
.El
.Pp
A line of the form ``<escape char>.'' disconnects from the remote host.
Similarly, the line ``<escape char>^Z'' will suspend the
.Nm rlogin
session, and ``<escape char><delayed-suspend char>'' suspends the
send portion of the rlogin, but allows output from the remote system.
By default, the tilde (``~'') character is the escape character, and
normally control-Y (``^Y'') is the delayed-suspend character.
.Pp
All echoing takes place at the remote site, so that (except for delays)
the
.Nm rlogin
is transparent.
Flow control via ^S/^Q and flushing of input and output on interrupts
are handled properly.
.Sh ENVIRONMENT
The following environment variable is utilized by
.Nm rlogin :
.Bl -tag -width TERM
.It Ev TERM
Determines the user's terminal type.
.El
.Sh SEE ALSO
.Xr rsh 1
.Sh HISTORY
The
.Nm rlogin
command appeared in
.Bx 4.2 .
.Sh BUGS
.Nm Rlogin
will be replaced by
.Xr telnet  1
in the near future.
.Pp
More of the environment should be propagated.
