Ahem??

'man ssh' on my system (Ubuntu Hardy) says:

     ssh exits with the exit status of the remote command or with 255 if 
an
     error occurred.

A quick test confirms this to be true. So clearly the exit status *is* 
propagated back. More likely it's just a problem with the OP's use of 
the Net::SSH API.

Now, the Net::SSH API documentation (*) for exec tells you:

   "success means that the command is being executed, not that it has 
completed"

And if it hasn't completed, obviously you can't get the exit status. I 
admit the documentation doesn't make it easy to see at a glance how you 
*should* get the exit status.

But in any case, I think it's not helpful to post unverified guesses 
about the behaviour of such a system.

Regards,

Brian.
