I have been trying for several weeks now to write a program that allows me to read the stdout of a process that I spawn and once I receive feedback, act appropriately.
More specifically, I need to create an SSH tunnel using plink on Windows XP. Once the tunnel is successfully created, then I need to run my program over that tunnel. If there is an error in the creation of the tunnel, then I need to abort and warn the users. My needs are 'small' but I just lack the know-how to get it done. I need to be able to spawn off plink so that it can continue to run in the background without interferring with the flow of my program. However, I would like to get the feedback to know if/when a successful connection has been made so that I know the appropriate actions to take. In the past, I spawned off a process using os.spawnl set into a thread and would pause for 10 seconds to give plink time to connect. However, it probably goes without saying this is not the best solution by any stretch of the imagination. My old command was (with obviously fake data): os.spawnl(os.P_NOWAIT, 'plink', 'plink', '[EMAIL PROTECTED]', '-N', '-L 111:200.200.200.200:7000') Then I would poll Windows to see if plink had started. If it hadn't started, I would raise an exception. However, there are plenty of times where plink starts but no connection is made. As with most questions like this one, any and all help would be greatly appreciated. Lewis -- http://mail.python.org/mailman/listinfo/python-list
