CRAP! Lets try that again.

It's amazing how many errors you notice when you are about to put your code up for public scrutiny. Hopefully everyone wont get so carried away correcting parts of the code that are inefficient that they forget about my origional problem.

Again, thanks in advance.

    I'm afraid this has become mashed too. Best to post code between <CODE> </CODE> tags otherwise any [ or ] will get mangled. The full details are here.

    You can also go back and edit something you posted (this isn't usenet ;-)

      ok. How does it look to you now? It was ok for me but then again I have my browser maximized on a 1280x1024 screen w/ small fonts.
        That looks fine now!

        I can only think of one thing - are you su-ing to root maybe to run this test program? Maybe the fact that your stored and effective uid are different causes problems when you run rsh from perl (which is starting another shell to do it?). Therefore rsh thinks you are someone else and asks you for the password.

        You could try my suggestion of running the system() with an array of things in so as not to invoke another shell - this might help. Then again it might be perl doing it...

        I always use scp/ssh for this sort of thing and I've never had a problem with it like that. You might need to put a -n on the rsh command line if you run it from a crontab though.
