problem getting packages for slink

["Tam, Vincent" <vincent@aib.net>]

Hello,

We have some servers still running old version of slink and don't want
them to potato yet. However we still want to update our slink distribution.
After we change the apt-get sources.list to:

deb ftp://ftp.debian.org/debian slink main contrib non-free

And updated the package information, while the apt-get try to download
update packages, it refer to "main", the potato, instead of "slink"!!

What can we do?

Please reply by e-mail if possible, thanks!!!
