Help with SVN

[Robe]

Hi,

I'm trying to do a checkout from "google projects" with this command

svn checkout
http://google-coredumper.google.com/svn/trunk/google-coredumper

And I get the following error

svn: PROPFIND request failed on '/svn/trunk'
svn: PROPFIND of '/svn/trunk': Could not resolve hostname
`google-coredumper.google.com': Temporary failure in name resolution
(http://google-coredumper.google.com)

Can someone help me with this?

I'm behind a proxy that require authentication.

Thanks,

Robe.
