The person with the best understanding of that is me. If you can get access to this machine, I'd be willing to help you do some test and send you some code to test with. However, if this needs to be through some other persom, the pain/benefit ratio might be getting a bit too high. > I'm thinking that the only way we are going to fix this is for them to poke > holes for our two servers in thier firewall, but if there is anything we can > do to do a little less than that, we'd appreciate any ideas. Well, I just tried ftp from my home machine which is behind an iptables-based nat-int firewall. I KNOW active FTP isn't going to work from there. From this I conclude that urllib2 uses passive ftp (as I suspected). It leaves me at a loss as to what the problem could be with yum/urlgrabber/urllib2. As I said, I'd be willing to pursue this if you think it's a problem on "our end". I recommend you start with these two things: 1) use some other ftp client from that machine to grab the same file 2) use urlgrabber directly to grab it, as in python2 urlgrabber.py ftp://server.com/path/to/file local_copy See what happens with those. -Michael -- Michael Stenner Office Phone: 919-660-2513 Duke University, Dept. of Physics mstenner@xxxxxxxxxxxx Box 90305, Durham N.C. 27708-0305
