I try to setup a VPN connection to ItsHidden on Ubuntu 9.10. I double-checked my credentials in the VPN configuration, but I don't think that this is problem. In my syslog I got these messages:

Because the gethostbyname is failing, I suppose that the NetworkManager doesn't know that I use proxies for accessing Internet. I'm not sure that this is the real problem.

Could you tell me a solution to make gesthostbyname not failing anymore?
