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 direc-
tories. Each line in this file contains two names: a host-
name and a username separated by a space. An entry in a re-
mote 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 either 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 ter-
minal or window size is also copied to the remote system if
the server supports the option, and changes in size are re-
flected as well. All echoing takes place at the remote
site, so that (except for delays) the remote login is tran-
sparent. Flow control using Ctrl-S and Ctrl-Q and flushing
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.
1
rlogin(1) USER COMMANDS rlogin(1)
-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 connec-
tion 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 charac-
ter, 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

rsh(1), stty(1), tty(1), named(1M), hosts(4),
hosts.equiv(4).
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 sys-
tem.
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.
