Re: Redirect stdout from SSH

No, sorry.  At least not without some details of what you did.  Like I said,
the simple example I put together worked fine for me so it seems clear that
there's a detail which is missing that accounts for the behavior you're 
seeing.  Did you try that example?  If you need me to, I can send the code,
though it just invokes 'ssh' as you describe via 'system()'.  

If you can point to how your example is different than mine or provide a simple example that shows the problem, that might help.
