Hi,
have you already configured your machine for rsh ?
If not then it's important to know, whether you are trying rsh from another AIX machine or from a Windows machine...
If you're on a Windows machine you cannot execute rsh with root permissions. So you'll have to configure it for a normal user....
There's also a syntax error. The correct syntax would be like that:
rsh 10.20.3.1 -l simon "date"
this would execute the command "date" on the machine 10.20.3.1 under user simon. If you're on an AIX machine you can replace simon with root, but first you'll have to configure the whole thing to allow rsh access...
If you need information on how to configure rsh on your AIX machine (it's quite easy) just say so ...
Regards
Thomas
