I'm a little surprised that these other programs work if they cannot resolve the name. > Is this the expected situation with yum at the moment: > yum 2.6.0-1 > rpm 4.4.2-15.2 Without DNS lookups... I'd have to say "yes"... that's precisely what I expect to happen :) I'm absolutely willing to look into this, but the offending code is almost certainly part of the core python modules and not something authored by us... as such, it's harder to solve those problems with severely ugly hackery. Please confirm that I'm grasping the situation... are you saying that these other programs "blindly" ask the proxy to connect them and let the proxy do the lookup? I certainly understand that it would work. I'm just making sure that's what's going on. -Michael -- Michael D.
