Subject Re: Question re sshexec task
Date Mon, 19 Dec 2005 12:25:18 GMT
Thanks for providing the example of exec.
I have questions:
Which system is the ant script running on?
Is the <exec> also executing on that system?

I am looking for a way to remotely execute ant code on multiple systems and
with multiple executions per system.

I have gotten sshexec to work (once per script).
rexec has issues, too.
