NAME
rlogin - remote login (Kerberos)
SYNOPSIS
rlogin rhost [-7][-8
][-ee][-f/F][-k realm][-l
username][-P]
rhost [
-7][-8
][-ee][-f/F][-k realm][-l
username][-P]
DESCRIPTION
The
rlogin command connects your terminal on the local host to the remote host (rhost).
rlogin acts
as a virtual terminal to the remote system. The host name rhost can be either the official name or an alias
as listed in the file
/etc/hosts (see hosts(4)).
The terminal type specified by the current
TERM environment variable is propagated across the network
and used to set the initial value of your
TERM environment variable on the remote host. Your terminal
baud rate is also propagated to the remote host, and is required by some systems to set up the pseudo-
terminal used by
rlogind (see rlogind(1M)).
All echoing takes place at the remote site, so that (except for delays) the remote login is transparent.
If at any time rlogin is unable to read from or write to the socket connection on the remote host, the
message Connection closed is printed on standard error and rlogin exits.
In a Kerberos V5 Network Authentication environment,
rlogin uses the Kerberos V5 protocol to authen-
ticate the connection to a remote host. If the authentication is successful, user authorization will be per-
formed according to the command line options selected for
rlogind (i.e., -K, -R, -r,or
-k). A pass-
word will not be required, so a password prompt will not be seen and a password will not be sent over the
network where it can be observed. For further information on Kerberos authentication and authorization
see the Secure Internet Services man page, sis(5) and rlogind(1M).
Although Kerberos authentication and authorization may apply, the Kerberos mechanism is not applied to
the login session. All information transferred between your host and the remote host is sent in cleartext
over the network.
Options
rlogin recognizes the following options. Note that the options follow the rhost argument.
-7 Set the character size to seven bits. The eighth bit of each byte sent is set to zero
(space parity).
-8 Use an eight-bit data path. This is the default HP-UX behavior.
To use eight-bit characters, the terminal must be configured to generate either eight-
bit characters with no parity, or seven bit characters with space parity. The HP-UX
implementation of rlogind (see rlogind(1M)) interprets seven bit characters with
even, odd, or mark parity as eight-bit non-USASCII characters. You may also need to
reconfigure the remote host appropriately (see stty(1) and tty(7)). Some remote hosts
may not provide the necessary support for eight-bit characters. In this case, or if it is
not possible to disable parity generation by the local terminal, use the
-7 option.
-ee Set the escape character to e. There is no space separating the option letter and the
argument character. To start a line with the escape character, two of the escape char-
acters must be entered. The default escape character is tilde (˜). Some characters
may conflict with your terminal configuration, such as ˆS, ˆQ, or backspace. Using
one of these as the escape character may not be possible or may cause problems com-
municating with the remote host (see stty(1) and tty(7)).
-f Forward the ticket granting ticket (TGT) to the remote system. The TGT is not for-
wardable from there.
-F Forward the TGT to the remote system and have it forwardable from there to another
remote system. -f and -F are mutually exclusive.
-k realm Obtain tickets from the remote host in the specified realm instead of the remote host’s
default realm as specified in the configuration file krb.realms.
-l username Set the user login name on the remote host to username. The default name is the
current account name of the user invoking rlogin.
