http is only possible when i use a proxy. Currently i've set http_proxy
to a neighbour machine, namely http://192.168.60.111:8888/. (by using
tinyproxy in debian)
Also, one more thing i'd like to mention, when i install debian on this
machine, i try to install sid via internet. The weird thing is that it's
unable to download packages from internet. I've even waited one day to
see whether it would work. But suprisingly, it just stops at the step
trying to download packages, no progress, no error too. Looks like it
has fallen into some strange loop.
While, again, after i set a http proxy first, it starts installing
quickly and successfully.

Yes. And ping everything looks okay.

Connection has been reset.

The one with the same hardware also has this problem first, then he has
switched to ubuntu 6.06(kernel seems 2.6.15).

No.
All in all, I doubt there are some network related flaws between linux
kernel and the dell machine. I think i might try another kernel with
different version later.
