remsh _without_ a command is just "rlogin", so probably rlogin is denied for
some reason on that machine.
PS: rcp and remsh normally connect to the "remshd" on the remote machine,
rlogin and remsh "without a command" to "rlogind" there and these daemons
can be secured separately in the security file (/var/adm/inetd.sec)
(or, when you have installed them, by the tcp wrappers).
Note that for NON-privileged users rlogin should aks for a password, unless
the ORIGINATING machine is either in the /etc/hosts.equiv OR the .rhost file
of THAT user on the target machine. remsh "command" and rcp never ask for a
password and can only be done through the hosts.equiv (non-privileged users
ONLY) and/or .rhosts file(s). ROOT always uses its .rhosts file only.
When "rlogind" is started with the -l option (in /etc/inetd.conf mostly) the
usage of .rhosts is DISabled for non-privileged users.
