Re: [SLUG] where to get an Ethernet hub (NOT a switch)

2009-07-18 Thread Martin Visser 
I think you will find getting a hub pretty hard these days - no one builds
them. Presumably you need one so that you can send a copy of traffic for
something link Wireshark or Ntop to analyse. Your best bet these days is to
find a small manageable switch that supports port mirroring. HP ProCurve
have the 1700-8 which is 10/100 and supports mirroring of any number of the
ports to one port. (Also supports VLANs as a bonus). The big advantage is
that once you have set it up you can rearrange the ports you want mirrored
as you need without having to rearrange patching like you would with a hub.

Can be your for under $150 locally. (You will probably find that Linksys and
Netgear both have similar low-end managable switches for around the same
price range).

 Hello,

 I'm looking for an Ethernet hub to be used for network troubleshooting
 (trying to find which of our hosts is involved in the load on our
 office uplink).

 So far eBay came up with only one option in Australia (which is a
 modem, and therefore apparently there is more competition on it) and
 one in the US (which adds to shipping cost and time).

 Does anyone here knows where can I get an Ethernet hub in Australia,
 preferably where I can get it quick to Sydney area, and not so
 expensive?
 (it seems that current hub models are expensive security-related ones,
 not justifiable for my requirements).

 100Mbit would be preferable, but maybe not essential if we connect it
 between the router/firewall and the SHDSL modem.

 Thanks,

If you want to do greedy packet capturing, I suggest using 'port
mirroring', a feature found on many business model switches. Failing
that, you can make a trivial two port switch out of a linux machine with
brtools.
