Is there anyone that is aware of a low cost 4 port 10/100/1000 MB hub that is available? There seems to be a lot of switches around but not any hubs. I am looking for something I can easily insert in an Ethernet network to look at traffic on a given segment of the the network. I currently use a Netgear DS104 for that purpose but that is only 10/100.
I was afraid of that. Is there any alternative, other than Linux with=20 two NICs and iptables? Is there such a thing as 4 port 10/100/1000=20 switch that has one port that can mirror? You would think I am not the=20 only one looking for such an animal for portable use and that others=20 might already doing this somehow. =20
It is designed for a 19" rackmount (it is wide but shallow) but there is the HP ProCurve 1700 series, which offers an 8 port version.
In the small size, there is an 8 port ProCurve 2520G that looks to be about the size you might prefer, its data sheet suggests it does port mirroring - it also offers PoE which may be more than you want. I've no idea on pricing - being one of the cobler's children I rarely have shoes and then don't get them at retail.
I thought we had a winner here in the 1700 series at under $100.00 for 8 ports, even if it is a little large, but on closer inspection it would appear there is only one 1000 MB port. The other 7 appear to be 10/100 only.
The good news is that your comments led me to look at the entire line and it would also appear that the 1800 series does have all 8 ports at
10/100/1000. It is a little more expensive but there do not seem to be a lot of options around. I will keep looking to see what else is out there but at least I know there is at least one possible solution.
I think that is a little out of my league at almost $1000. I am retired and this would be for personal use, or at least used where I volunteer my time.
I now have another question but it would probably be better to start another thread.
The Procurve 1800 is getting hard to get now because it's been replaced by the 1810G series. The 1810G-8 seems to be the same price as the older 1800-8G model it replace, unless you can get a sweetheart deal on an outgoing model it may make more sense to get a 1810G-8 rather than a box with End Of Sale "1 Dec. 2009 or while supplies last".
It too supports port mirroring and seems to have a number of minor enhacements but I've not used one yet (at work we have a few 1800 and a lot of 1400 out in the "landscape" after we got burned by cheaper "consumer" switches failing and sabotaging the network).
At first I assumed you could get similar models from other manufacturers but if it has I couldn't find any in that kind of price range with a quick check with the usual suspects.
Thanks for the insight on the newer model. I think I will look around and see if there any deals for the unit that is sunsetting. I really do not need the latest and greatest and saving a few bucks is more important.
Not five minutes ago I was reading an email from one of the ProCurve types mentioning the 1810G-8 - I suspect that is the switch you have found. In an interesting bit of symmetry to the 2520G-8, he mentioned something about that switch being able to be powered *by* PoE.
It is unlikely that you will find a hub that works at 1000Mbps, especially in a multi-speed configuration. In any event, any device which operates at multiple speeds will be a combination of hub ports and internal bridges since, as has been mentioned already, true hubs operate at a single speed on all ports. What you want to look for is called a "network tap," which is wired inline with the uplink port on a switch or hub, and copies all traffic to a monitor port. As an alternative, you can use a switch which allows you to configure a "monitor port," which can be configured to copy all traffic to the monitor port.
