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.
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 character. Changes the remote username to the one you specify. Otherwise, your local username is used at the remote host.
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
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
On systems that do not support rlogin, you can use telnet (if supported) as an alternative.
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 specified.
The local host is included in a $HOME/.rhosts file in the home directory of the remote user account. If -l user is specified, the local
username must also be included in the 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 recommended.
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 normal 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: 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. To log in to a remote host with a differ-
ent 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. 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.
