I'm no expert on NIM configuration, but I believe the error is you need to have rsh and/or rlogin enabled on your target server. NIM uses the old "r" protocols, but most shops disable them for security reasons. Since your error is a permission denied from the rsh daemon I'd take a look at that.
Also, a good site for info on AIX error messages and codes is here:
http://publib.boulder.ibm.com/infoce...v5r3/index.jsp
Click on "AIX message center" in the left pane, then go to seven-digit error numbers to search for your code.
Here is the first few lines listed for error 0826-813. Since it mentions .rhosts that is even more evidence it is your "r" protocol config that needs fixing.
