Greetings of mighty gurus of CLUG:
I have a networking problem that is driving me up the wall, and refuses to be
solved by my miniscule amount of knowledge. It's not exactly a Linux question
- but I am running Debian etch on all relevant machines :-)
I recently had my house wired with Cat5 cabling by a contractor. For the kids
bedrooms (x4), the contractor ran a single cable down the shared wall and
wired up two pair to one socket, and two pair to the other. He then ran the
other end to a "patch panel" mounted in the security system's container. From
this panel, I have run short cables into a 5 port hub. Because of the way the
contractor wired the cables, the northern 2 bedrooms run into one hub socket,
and the southern 2 bedrooms run into another hub socket. The hub is then fed
back to my main hub, via a cross-over cable (which research seemed to suggest
should be used to connect two hubs together). The main hub then connects to
everything else (a couple more computers and the firewall).
My problem is that the connection between the "front" and "back" sections is
intermittent at best, with generally only one of the bedrooms being able to
connect to the "front" at any one time. The bedroom machines have been tested
to work properly and use DCHP for IP addresses on the network.
I have a suspicion that I can't run Cat5 in the way that it has been done and
expect all four machines to run at the same time, but I have no information
to back it up. Does any one have an idea why it might be failing, or,
alternatively does any one have a clue stick to beat me with?
Thanks in advance
Rob
