rlogin - Connects the local host with a remote host
rlogin [-8L] [-e character] [-l user] remote_host
The remote login command (rlogin) logs into remote_host and connects your
local terminal to the remote host.
-8 Allows an 8-bit data path at all times. Otherwise, unless the Stop and
Continue key sequences on the remote host are not standard, rlogin uses
a 7-bit data path and the eighth (high) bit of each byte is stripped.
Changes the Escape character. Substitute the character you choose for
Changes the remote username to the one you specify. Otherwise, your
local username is used at the remote host.
-L Allows the rlogin session to be run in litout mode. In this mode, the
escape sequence ~. (where ~ is the escape character) disconnects you
from the remote host and the escape sequence ~^Z (where ^Z, or Ctrl-Z,
is the suspend character) suspends the rlogin session if you are using
The remote terminal type is the same as that given in the local TERM
environment variable. The terminal or window size is also the same, if the
remote host supports them, and any changes in size are transferred. All
echoing takes place at the remote host, so except for delays, the terminal
connection is transparent. Pressing the Stop and Continue key sequences
stops and starts the flow of information, and the input and output buffers
are flushed on Interrupts. The rlogin command can only be used to connect
to systems that are running the rlogind daemon.
On systems that do not support rlogin, you can use telnet (if supported) as
If you do not specify the -l option, the local username is used at the
remote host. If -l user is specified, the username entered is used at the
remote host. In either case, the remote host allows access only if one or
both of the following conditions is satisfied:
+ The local host is included in the remote host's /etc/hosts.equiv file,
the local user is not the superuser, and the -l user option is not
+ The local host is included in a $HOME/.rhosts file in the home direc-
tory of the remote user account. If -l user is specified, the local
username must also be included in the .rhosts file.
If neither of these conditions is met and a password is defined for the
remote user account, the remote host prompts for a password. The remote
password file is checked to verify the password entered, and the login
prompt is displayed if the password is not correct. Pressing the End-of-
File key sequence at the login prompt ends the remote login attempt.
For security reasons, any $HOME/.rhosts file must be owned by either the
remote user or the root user and should have permissions set to 600 (read
and write by owner only).
In addition to the preceding conditions, rlogin also allows access to the
remote host if the remote user account does not have a password defined.
However, for security reasons, use of a password on all user accounts is
Unless otherwise modified by the -e option, the standard Escape character
for disconnecting from the remote host is a ~ (tilde). The Escape character
is only recognized by the remote host if it occurs at the beginning of a
line. Otherwise, the Escape character is sent to the remote host as a nor-
mal character. To send the Escape character to the remote host as a normal
character at the beginning of a line, press the Escape character twice.
Pressing the Escape character and a (dot) (for example, ~.) immediately
disconnects the local terminal from the remote host.
In the following examples, the local host is listed in the /etc/hosts.equiv
file at the remote host:
1. To log in to a remote host with your local username, enter:
$ rlogin host2
Password: <<Enter password>>
To log off the remote host and close the connection, enter the End-
of-File key sequence.
2. To log in to a remote host with a different username, enter:
$ rlogin host2 -l dale
You are prompted to enter your password and then are logged in to the
remote host host2 with the username dale.
3. To log in to host2 with the your local username and change the Escape
character to \ (backslash), enter:
$ rlogin host2 -e\\
Specifies remote hosts from which users can execute commands on the
local host (provided these users have an account on the local host).
Specifies remote users who can use a local user account.
