Hi All

I installed debian lenny just now and I use China Tele ADSL.
which source list should I use?
is the following sourcelist OK?
deb http://debian.cn99.com/debian lenny main non-free contrib
deb http://debian.cn99.com/debian lenny-proposed-updates main contrib non-free
deb http://debian.cn99.com/debian-security lenny/updates main contrib non-free

deb-src http://debian.cn99.com/debian lenny main non-free contrib
deb-src http://debian.cn99.com/debian lenny-proposed-updates main contrib non-free
deb-src http://debian.cn99.com/debian-security lenny/updates main contrib non-free
