Re: ALWLMTUSR

First of all LMTCPB only limits commands that have DSPCMD yourcommand 
showing
Allow limited user . . . . . . . . . . :   *NO


There are numerous ways to thwart LMTCPB(*YES).

1 - as a further example to your question try this from your PC, assuming 
you're a Wintel / iSeries Access equipped client.
Start, Run, Cmd
then, in the DOS window,
rmtcmd //youriseriesName  DSPUSRPRF yourusrid output(*print)
And, even though DSPUSRPRF says Allow limited user . . . . . . . . . . : 
*NO, you will create a spool file even if your user profile is set up for 
LMTCPB(*YES)

2 - On older versions of OS/400 you used to be able to FTP to it and do 
something like:
quote rcmd dspusrprf yourusrid output(*print)
and it would work.  IBM tightened this one down.

3 - I suspect various Client Server and/or web applications would not 
respect this.

4 - RUNRMTCMD does seem to respect LMTCPB(*YES)

ALWLMTUSR






Preparing for a security audit on our iSeries i set LMTCPB(*YES) for some 
users.

But i read, and ask for a confirm, that the user can't execute commands 
with ALWLMTUSR *YES, and
now i can't figure out  any method to retreive the list of command with
the parameter ALWLMTUSR *YES; is there any way to obtain such a list ?


And more, stated that the next paragraph is true:

"Security Warning: Don't rely on LMTCPB(*YES) to restrict command usage. 
IBM's distributed data management (DDM) architecture doesn't evaluate this 

attribute when an incoming Remote Command (RMTCMD) command is executed. 
So, users with LMTCPB(*YES) could still run commands using DDM's RMTCMD, 
which is simple to do when using Client Access Express."

is LMTCB really related to security ?


thank you
