Hi,
The ftp site (all ftp://*.alioth.debioan.org) isn't working (at the moment??). So this is not limited to the shadow package. If individual packages are needed use http:// instead of ftp://
One can also use
LFS ftp packages to get individual packages or a complete tarbal (at this moment LFS 6.8 is not yet included, but I guess it will be shortly).
