rsync from 10.4 to current daily?

[Jim Cheetham]

OK, I've got the 10.4 warty iso file, and I wanted to try the latest 
daily build on a new install I'm trying ...

The wiki suggests that I can rsync the daily file ...
$ rsync archive.ubuntu.com:/cdimage/daily/current/warty-i386.iso .

But I get no response ... only [SYN]s sent, no [ACK]s, so there's no 
rsync server listening there ...

$ rsync cdimage.ubuntu.com:/daily/current/warty-i386.iso . doesn't work 
either ...

What's the correct way to rsync the daily builds?
