I've experimented, before, with logging in using the Seamonkey browser to navigate the restricted directory tree. Using a trial and error approach, with my PowerPack subscription account authentication credentials, I can see the 2010.1 directory for PP isos here:
https://user%40domain.com:password@dl1.mandriva.com/pwp/2010.1/
where, obviously, I have obscured my credentials such that
- user%40domain.com is my log in email address, with @ replaced by %40 followed by colon, : and
- password is password for my log in, don't you know
I don't know if this is helpful to Dan Åsen Hansen but think it is a fun tip and maybe someone could pass it along, in case it helps.
