rlogind

Synopsis

                  in.rlogind [options]

TCP/IP command. Server for the rlogin program, providing a remote login facility, with authentication based on privileged port numbers from trusted hosts. rlogind is invoked by inetd when a remote login connection is requested, and executes the following protocol:

  • The server checks the client’s source port. If the port is not in the range 512-1023, the server aborts the connection.

  • The server checks the client’s source address and requests the corresponding hostname. If the hostname cannot be determined, the dot-notation representation of the host address is used.

The login process propagates the client terminal’s baud rate and terminal type as found in the TERM environment variable.

Options

-a

Verify hostname.

-h

Permit superuser .rhosts files to be used. Ignored if pluggable authentication module (PAM) support is enabled. Control through /etc/pam.conf instead.

-l

Do not authenticate hosts via a nonroot .rhosts file. Ignored if pluggable authentication module (PAM) support is enabled. Control through /etc/pam.conf instead.

-n

Suppress keep-alive messages.

-L

Do not authenticate hosts via .rhosts or hosts.equiv files. Ignored if pluggable authentication module (PAM) support is enabled. Control through /etc/pam.conf instead.
