RLOGIN(1) BSD General Commands Manual RLOGIN(1)NAMErlogin — remote login
SYNOPSISrlogin [-468DEd] [-e char] [-i localname] [-l 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 transpar‐
ent 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
/etc/auth.conf
$HOME/.rhosts

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.
