RLOGIN(1)               FreeBSD General Commands Manual              RLOGIN(1)

NAME
     rlogin - remote login

SYNOPSIS
     rlogin [-468DEd] [-e char] [-i localname] [-l username] host

DEPRECATION NOTICE
     rlogin is deprecated and will be removed from future versions of the
     FreeBSD base system.  If rlogin is still required, it can be installed
     from ports or packages (net/bsdrcmds).

DESCRIPTION
     The rlogin utility starts a terminal session on a remote host host.

     The standard Berkeley rhosts authorization mechanism is used.

     The following options are available:

     -4    Use IPv4 addresses only.

     -6    Use IPv6 addresses only.

     -8    Allow 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.

     -D    Set the TCP_NODELAY socket option which can improve interactive
           response at the expense of increased network load.

     -E    Stop any character from being recognized as an escape character.
           When used with the -8 option, this provides a completely
           transparent connection.

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

     -e    Allow 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.

     -i    Allow the caller to specify a different local name to be used for
           authentication.  This option is restricted to processes with uid 0.

     -l    Specify a different username for the remote login.  If this option
           is not specified, your local username will be used.

     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 session, 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.

ENVIRONMENT
     The following environment variable is utilized by rlogin:

     TERM  Determines the user's terminal type.

FILES
     /etc/hosts
     /etc/hosts.equiv
     $HOME/.rhosts

SEE ALSO
     login(1), rsh(1), telnet(1), setsockopt(2), ruserok(3), tty(4), hosts(5),
     hosts.equiv(5), rlogind(8), rshd(8)

HISTORY
     The rlogin command appeared in 4.2BSD.

     IPv6 support was added by WIDE/KAME project.

BUGS
     The rlogin utility will be replaced by telnet(1) in the near future.

     More of the environment should be propagated.
