SYNOPSIS

     rlogin [-8EKLdx] [-e char] [-k realm] [-l username] host


DESCRIPTION

     Rlogin starts a terminal session on a remote host host.

     Rlogin first attempts to use the Kerberos authorization mechanism, de-
     scribed below.  If the remote host does not supporting Kerberos the stan-
     dard Berkeley rhosts authorization mechanism is used.  The options are as
     follows:

     -8    The -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 .

     -E    The -E option stops any character from being recognized as an es-
           cape character.  When used with the -8 option, this provides a com-
           pletely transparent connection.

     -K    The -K option turns off all Kerberos authentication.

     -L    The -L option allows the rlogin session to be run in ``litout''
           (see tty(4))  mode.

     -d    The -d option turns on socket debugging (see setsockopt(2))  on the
           TCP sockets used for communication with the remote host.

     -e    The -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 \nnn.

     -k    The option requests rlogin to obtain tickets for the remote host in
           realm realm instead of the remote host's realm as determined by
           krb_realmofhost(3).

     -x    The -x option turns on DES encryption for all data passed via the
           rlogin session.  This may impact response time and CPU utilization,
           but provides increased security.

     A line of the form ``<escape char>.'' disconnects from the remote host.
     Similarly, the line ``<escape char>^Z'' will suspend the 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.

     All echoing takes place at the remote site, so that (except for delays)
     the rlogin is transparent.  Flow control via ^S/^Q and flushing of input
     and output on interrupts are handled properly.


KERBEROS AUTHENTICATION

     Each user may have a private authorization list in the file .klogin in
     their home directory.  Each line in this file should contain a Kerberos
     principal name of the form principal.instance@realm. If the originating

     TERM  Determines the user's terminal type.

HISTORY

     The rlogin command appeared in 4.2BSD.


BUGS

     Rlogin will be replaced by telnet(1) in the near future.

     More of the environment should be propagated.
