backbone on lan?

[Dutch Woman]

if you were @ a LAN lets say 10 ppl and 2 of those machines had 2 Lan cards each, could i set of those LAN card be plugged into the hub/switch using a straight thru and the other 2 be attached via a patch cable between the 2 mentioned machines to act as a dedicated backbone?

Both the cards and the switch you are plugging them into have to support trunking for you to connect them together (as far as I know).

Just checking : You want to use a cross-over cable to connect two computers, and then using their other network cards, hook them into the switch?

Be better to use a switch to switch mentions

I'd would only do this when in a situation. Where your got 3 switches with a Gigabit uplink ports. using 3 Gigabit cards in a deicated system linking them together. using a decicated backbone and using it for normal gaming or serving maybe a bad idea (CPU)

[gottathink]

sounds like a waste of time, windows wouldnt know how to route between them (I dont know of any third party software to do it either)

now if the 2 machines with 2nics were running linux it would be a different story...

actually if you just wanted to do ftp or something between them you could manually set ips (on a different subnet to the other network, easy, assuming you have w2k or XP) for the 2 spare nics and use this ip for connecting between them

I'm a little bit confused... could you clarify?

Anyway, was there a reason why you can't plug all of the NICs into the switch (including the total of four in the servers?) Is there a limited number of ports that prevents you from doing this, or is it something a little bit deeper?

correct me if i'm wrong but all you want to do is essentially have a little private network between 2 computer for, say, dirty amounts of leeching all night, while still being hooked up to the main network??? Like such:

to main network<-----PC1<----->PC2----->to main network

none of this trunking or routing crap (trunking needs to be supported on the switch as nodes have nothing to do with trunking or VLANs etc).

It can be done easily.
Just use a cross-over between the 2 computers and set an IP address of say, 10.1.1.1/24 and 10.1.1.2/24 on those and then use normal cable from each PC to the main network with the assigned address. make sure you turn off network connection sharing and the like cause it may cause problems

This will explain it better

Ingredents:
3 x Switches with a Gigabit Uplink port
3 x network cables
1 x computer with 3 Gigabit NIC

Method
1. setup the switches
2. setup computer with 3 GIGABIT NIC
3. Connect one end of each network cable into the uplink port into the switch and insert the other ends into one of the Computers NIC's

Hey presto you have a low ping network

At my local lan we normally use 2 100Mb switches, we haven't got gigabit yet. Our CS server is running Mandrake 9, if i got 2 Intel Pro NICs for the server and connected one to each switch would that increase the bandwidth to the server.

hang on so u have a 8 port switch but have 10 people to connect to the switch, so u want to "daisy chain" 2 pcs threw 2 other pcs connect to the switch to u can have 10 people on a 8 port switch?? kinda confusing

do u mean something like this?



sorry about my l33t paint skills, but do u mean something like this or something else?

[Dutch Woman]

sorry guys i must not have explained myself well enuff.

me and a friend want to have 2 NICs in each of our PC's

as such

1st NIC in my PC: A
2nd NIC Second in my PC: B
1st NIC in friends PC: C
2nd NIC in friends PC: D


we want to have NIC's A and C conected to the switch via straight-thru cables and Nics B and D connected via a patch cable from PC to PC. So when we communicate we dont get slow down because of traffic. BTW we are just using crappy Realtek 10/100 NICs

i would post a pic but i dont have he available webspace

exactly what i was getting at in my previous post. do what i have explained above. Make sure you are on the same network but totally differnet to that of the main network. best way to make sure this happens is to use addresses like this:

PC1:
10.1.1.1/255.255.255.252

PC2:
10.1.1.2/255.255.255.252

That's for your little private network, then just use DHCP or whatever on the main network.

just don't bridge the connections or anything funky like that

Updated my pic, is that what u mean?

Yep - just give the dedicated link a different subnet (IP range) and you'll be OK. Also - if you're using windows networking, connect via IP rather than name, otherwise you could use the switched connection.

eg: \\10.1.1.1\share instead of \\computername\share

You may have trouble with some LAN games - they're not always designed to cope with multihomed PC's. Some games have bind options to let you select the right card.

Cause they crew up alot of CPU Power some chipsets NICS do.

If you have someone leech off you before while your playing a Lan game you know what sort of performance your gonna get

Perhaps even worser when a computer uses 2 Nic's

Edit : If you gonna use 2 NIC in 2 machines, It's better if he sells them and gets himself a 5 port'er from PCRANGE.biz
