rlogin

NAME

rlogin - remote login

SYNOPSIS

rlogin [-8ELDd] [-e char] [-l username] host

DESCRIPTION

The rlogin(1) utility starts a terminal session on a remote host host. The host name can be specified in either name or numeric dot notation.

The rlogin(1) utility first attempts to use the Kerberos authorization mechanism, described later in this topic. If the remote host does not support Kerberos, the standard Berkeley .rhosts authorization mechanism is used. The options are as follows:

-8

The -8 option allows an eight-bit input data path at all times; otherwise, parity bits are stripped except when the remote side's stop and start characters are other than ^S/^Q.

-D

The -D option prefixes both the remote and local user names with the user's Windows domain name. (By default, both remote and local user names are the user name without the domain.) The argument to the -l option will always override the remote user name value. This option should only be used when connecting with another Interix system.

-d

The -d option turns on socket debugging (see setsockopt(3)) on the transmission control protocol (TCP) sockets used for communication with the remote host.

-E

The -E option stops any character from being recognized as an escape character. When used with the -8 option, this provides a completely transparent connection.

-e

The -e option allows user specification of the escape character, which is ~ by default. This specification can be as a literal character, or as an octal value in the form \nnn.

-K

The -K option turns off all Kerberos authentication.

-L

The -L option allows the rlogin session to be run in "litout" (see tty(1)) mode.

-l

The -l option specifies a different username for the remote login. If this option is not specified, your local user name will be used.

A line of the form escape_char. (that is, the escape character followed by a period) disconnects from the remote host. Similarly, the line escape_char followed by CTRL+Z (^Z) suspends the rlogin(1) session, and escape_char followed by delayed-suspend_char suspends the send portion of the rlogin, but allows output from the remote system. By default, the tilde (~) character is the escape character, and CTRL+Y (^Y) is usually the delayed-suspend character.

All echoing takes place at the remote site, so that (except for delays) the rlogin(1) is transparent. Flow control through ^S/^Q and flushing of input and output on interrupts are handled properly.

Interix authentication

• If the daemon is running as the user SYSTEM, this will work.
• If the daemon is not running as SYSTEM, the password of the account used to run the daemon must be stored using the regpwd(1) utility.
• If the iruserok(3) function indicates that the address might have been spoofed, the user will be prompted for a password, regardless of the user identifier (ID) of the daemon.

• (The test is done by converting the host number to a host name and then converting the host name to a host number; if the two host numbers do not match, the address might have been spoofed. A user can get similar results by using nslookup(1) to check both the host name and the host number.)

NOTES

If the name of the binary is a host name (that is, if there is a hard link to rlogin(1) that is the name of a known host), rlogin(1) automatically opens a connection to the host.

FILES

The rcp(1) and rshd(1) programs make use of the following files, if they exist:

/etc/hosts.equiv

On the target system, this file contains the names of systems and users allowed to login. See rlogind(1) for more information.

$HOME/.rhosts

On the target system, this file can contain the names of systems (and user names) allowed to login. See rlogind(1) for more information.

ENVIRONMENT

The following environment variable is utilized by rlogin:(1)

TERM

Determines the user's terminal type.

BUGS

More of the environment should be propagated.
