RLOGIN(1)

NAME
rlogin - remote login

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

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

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.
