[Pharo-project] NetNameResolver problem on Linux Ubuntu 9.04

Hi all, Since one week I have network problems: system update is not working, Monticello can't open any http repository... I've investigated a little bit and found that NetNameResolver always fail when trying to resolve www.squeaksource.com as an example: NetNameResolver addressForName: 'www.squeaksource.com' result is always nil. I can make it work only by setting true to the #UseOldNetwork NetNameResolver class variable. I'm on Ubuntu 9.04, I'm using Exupery VM 0.15.1. I do not have any problem on a VirtualBox/Ubuntu 8.10, same VM. Cheers Alain
