Hi

2 network cards in one tower, run XP pro

Trying to get 2nd card to link to another machine ( white Box )


XP pro first network card is running and surfing, 2nd card tells me no net work cable not contected..

I hope some one can under what i'm on about,

any ideas please, i'm at a lost to this

TT

When you directly connect two computers with ethernet (not with a hub/switch/router) you have to use a crossover cable instead of a normal cable.

I was thinking about that when putting the cable in, I'll give it a shot. If i can find the cable.

Thanks

Ok that seems to work ok.

do i use the same config as the other network card as in IP etc.

I did put in 192.168.x.x etc and my surfing droped out, i un did what i did and its back up as in surfing etc...

but i may have to reboot white box..

If you set a default gateway pointing out of the second card then packets addressed to machine out on the internet will go out of that card instead of towards your internet connection.

You should probably have to second card in a different subnet.

I know what you mean by subnet as in ( 255.255.255.0 ) I hope thats right

as to other bit, well thats another story, do you mean 255.0.0.0 ???

>I know what you mean by subnet as in ( 255.255.255.0 )

That's a subnet mask not a subnet.
A subnet is a range of ip addresses like 192.168.0.0 to 192.168.0.255

192.168.0.0 with a mask of 255.255.255.0 is 192.168.0.0 to 192.168.0.255

192.168.1.0 with a mask of 255.255.255.0 is 192.168.1.0 to 192.168.1.255


>do you mean 255.0.0.0 ???

No, you would be surprised how many people use that as a mask with 192.168.x.x addresses then wonder why they can't reach some website's such as adobe.com at 192.150.14.120

here is what i have from the Xp command line

Ethernet adapter ADSL:

Connection-specific DNS Suffix . :
IP Address. . . . . . . . . . . . : 192.168.x.x
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.x.x

Ethernet adapter White Box:

Connection-specific DNS Suffix . :
Autoconfiguration IP Address. . . : 169.254.x.x
Subnet Mask . . . . . . . . . . . : 255.255.0.0
Default Gateway . . . . . . . . . :

I take it that the white box eth0 has to be some thing like this

Autoconfiguration IP Address. . . : 169.254.x.x
Subnet Mask . . . . . . . . . . . : 255.255.0.0
Default Gateway . . . . . . . . . :192.168.x.x

Its just a guess

Removing 192.168.x.x and 169.254 addresses does not provide any security. Those addresses do not work across the internet.

If the 169.254 address has been set automatically by windows you can't rely on it staying the same.


Autoconfiguration IP Address. . . : 169.254.x.x
Subnet Mask . . . . . . . . . . . : 255.255.0.0
Default Gateway . . . . . . . . . :192.168.x.x

The default gateway should be the 169.254.x.x address of the other machine. If you want the whitebox machine to be able to contact machines on the other side of the XP box you will have to turn on ip forwarding in the XP machine and configure a route on the other side of the LAN.
