You have definitely discovered a security hole!
Secure/Net (exit point security & network access control software) can help you 
with this, and
other, security gaps...

I think I have found a potential "hole" but maybe I am missing something,
and one of the "experts" out here can help.

Scenario1:

Sign on to Microsoft Windows with User=Mark (same as 400 user id) and no
password (I know bad, but......)

At this point no Client Access session program has been started from client
PC.

Do RMTCMD /I d:\web\Command.lst

Commands execute as specified but no AS/400 sign on is required.


If I do a DSPLOG after executing command I see

 Cause . . . . . :   The *SIGNON server is processing request 1 for user
MARK.
   The types of requests supported are as follows:
     1 -- Retrieve Signon Information
     2 -- Change Password


Other msg's that appear:

*SIGNON server job 704972/QUSER/QZSOSIGN processing request for user MARK on
Job 704981/QUSER/QZSCSRVS started on 05/18/00 at 12:04:12 in subsystem

sub
Job 704982/QUSER/QZSCSRVS started on 05/18/00 at 12:04:12 in subsystem
QSYSWR

If I sign on to my PC as HACKER (BTW not a valid AS/400 signon) and try the
rmtcmd I get the Client Access pop up window asking for userid and password.

Short of requiring/enforcing every one to have Windows passwords is there
any other way to restrict RMTCMD??
I do want specific user profiles to be able to execute w/o having to sign on
to the as/40 (i.e. scheduled running of .BAT at specified time from a PC).
