rlogin(1N) (TCP/IP) rlogin(1N)
NAME
rlogin - remote login
SYNOPSIS
rlogin [ -L ] [ -8 ] [ -e c ] [ -l username ] hostname
DESCRIPTION
rlogin establishes a remote login session from your terminal to the
remote machine named hostname.
Hostnames are listed in the hosts database, which may be contained in
the /etc/hosts file, the Internet domain name server, or in both.
Each host has one official name (the first name in the database
entry), and optionally one or more nicknames. Either official
hostnames or nicknames may be specified in hostname.
Each remote machine may have a file named /etc/hosts.equiv containing
a list of trusted hostnames with which it shares usernames. Users
with the same username on both the local and remote machine may
rlogin from the machines listed in the remote machine's
/etc/hosts.equiv file without supplying a password. Individual users
may set up a similar private equivalence list with the file .rhosts
in their home directories. Each line in this file contains two
names: a hostname and a username separated by a space. An entry in a
remote user's .rhosts file permits the user named username who is
logged into hostname to log in to the remote machine as the remote
user without supplying a password. If the name of the local host is
not found in the /etc/hosts.equiv file on the remote machine, and the
local username and hostname are not found in the remote user's
.rhosts file, then the remote machine will prompt for a password.
Hostnames listed in /etc/hosts.equiv and .rhosts files must be the
official hostnames listed in the hosts database; nicknames may not be
used in either of these files.
To counter security problems, the .rhosts file must be owned by ei-
ther the remote user or by root.
The remote terminal type is the same as your local terminal type (as
given in your environment TERM variable). The terminal or window
size is also copied to the remote system if the server supports the
option, and changes in size are reflected as well. All echoing takes
place at the remote site, so that (except for delays) the remote lo-
gin is transparent. Flow control using CTRL-S and CTRL-Q and flush-
ing of input and output on interrupts are handled properly.
The following options are available:
-L Allow the rlogin session to be run in litout mode.

-8 Pass eight-bit data across the net instead of seven-bit data.
-e c Specify a different escape character, c, for the line used to
disconnect from the remote host.
-l username
Specify a different username for the remote login. If you do
not use this option, the remote username used is the same as
your local username.
Escape Sequences
Lines that you type which start with the tilde character are escape
sequences (the escape character can be changed using the -e options):
~. Disconnect from the remote host - this is not the same as a
logout, because the local host breaks the connection with no
warning to the remote end.
susp Suspend the login session (only if you are using a shell with
Job Control). susp is your suspend character, usually CTRL-Z,
see tty(1).
FILES
/etc/passwd
/usr/hosts/* for hostname version of the command
/etc/hosts.equiv list of trusted hostnames with shared usernames
$HOME/.rhosts private list of trusted hostname/username
combinations

NOTES
When a system is listed in hosts.equiv, its security must be as good
as local security. One insecure system listed in hosts.equiv can
compromise the security of the entire system.
If you use a windowing terminal and you intend to run layers(1) on
the remote system, then you must invoke rlogin with the -8 option.
This implementation can only use the TCP network service.
