This rsh daemon does access control and logging in the style of the tcp
wrapper (log_tcp) package. It closes up a few holes.

By default, the rshd logs user@host with priority daemon.info (see
below for how to change this). You may have to adjust the syslog.conf
file to make the logs visible. Do not forget to "kill -HUP" the syslogd
if you change its setup.

By default, the rshd will not accept wildcards in hosts.equiv and
rhosts files, but will complain instead. If you want '+' wildcards see
below for how to turn them on.

Optionally logs the user command (-DLOG_COMMANDS, see Makefile).

Options of interest that are not described in the manual page:

-n

    Disable keepalives. Keepalives are useful when users turn off their
    machine without logging off.

-l

    Disable user .rhosts files except for the superuser.

Macros of interest (these are defined in the Makefile):

FACILITY

    The syslogging class. Default is LOG_DAEMON.

LOG_COMMANDS

    Turn on command logging. Disabled by default.
