need some networking help!

Tue May 11 16:00:59 UTC 2010

Hey folks,

I'm hoping there's someone out there who can help me with a networking
problem; I kind of doubt the issue is linux-based byt i suppose it's
possible.

Here's the deal:  I am building an ubuntu-based computer centre in the
basement of a social housing building in Kensington Market.  The
internet here comesi n via dsl to an 8-port router and is farmed out
from there to various computers and I believe a wireless outer
somewhere else in the building. I was hoping to connect a donated hub
(thanks PlanetGeek!) to the router and use the hub to serve out
internet service to the computers in our little cluster,but try as i
might I can't get a dhcp connection to work.

here's a little more info:

the hub is a D-link DES-1024R 10/100 switch. there's no serial console
& nothing in the manual about setting the switch up.
(manual is here:http://www.google.com/url?sa=t&source=web&ct=res&cd=1&ved=0CBIQFjAA&url=ftp%3A%2F%2Fftp.dlink.co.uk%2Fswitches%2Fdes-1016r%2Fdes-1016r_manual_v.02.pdf&ei=V33pS8ytDIP68Aahw9TmDg&usg=AFQjCNG9XxOyyCFBtkqn7JP5wZnVJJtFqA&sig2=EE4ha-MwDs8kkOZCU_Ep6g)

Attaching a straight-through cat-5 cable from the router to either the
uplink or one of the standard ports, I get solid green on both lights
for that port, indicating an active link.
attaching another cable from one of the other ports to my laptop, i
get two more green lights on that port, again indicating an active
link.

unfortunately, network-manager fails to connect (this is under ubuntu
lucid, so a recent n-m).

the same cables work fine for me if i hook my laptop directly into the
hub, so i know that's not the issue.

logs indicate that i'm getting a dhcp timeout; i've attached a sample
output from /var/log/daemon.log so you cna see what I mean.

Anyway, if anyone can help i'd be really grateful.  This is a
volunteer project, too -- if you feel like volunteering some time --
or if you think my switch is broken & you havea  better one -- by all
means let me know!  thanks much,

matt
