While I doubt very much that's a real quote, I'm pretty sure I'm the one who said it :) That's true. Frankly, I don't think yum/urlgrabber is the place to fix such quirky ftp behavior, but rather in ftplib (which is part of the standard python distro). However, this is a significant problem. If folks can provide me with a way to recreate such problems, I'd be happy to seriously look into them. Also, each of these messages leads me to think we should bump timeouts up on the priority list a bit. This may not be something timeouts can help though. How long will it hang? A few minutes? Hours? If the latter, it's probably broken ftp handling (possibly server, more likely client, conceivably both). In that case, timeouts won't help. -Michael -- Michael D.
