Hey All,
I have two computers, one running windows 2000 and one running SuSe linux.
There is a crossover cable between the two machines.
Could someone please post up a detailed explanation of how to connect the two machines that includes setting ip addresses, routing commands etc,.  (I am offering maxium points so please give exact instructions.)
All I have done so far is link the machines with the crossover cable but they can only ping themselves not each other, however I can't seem to configure the routing etc.
Thanks,
Stef

First and foremost, they must be on the same subnet.
If you're giving them private ip addresses, 192.168.1.100 and 192.168.1.101 - they both should have a subnet mask of 255.255.255.0.  You can set the gateway to be the ip address of the other machine or leave it as blank.

On the W2k machine, enable NetBIOS over TCP/IP:

Right-click your network connection/local area network and choose properties
Find your TCP/IP protocol, click it and click properties
  Click the Advanced button on the General tab.
  Click the WINS tab.
  Under NetBIOS setting heading
   Click Enable NetBIOS over TCP/IP
  Click OK to apply and close out the dialogue box...

I tried the above, still no change.
The cards can ping them selves but not eachother

wats your intention for this network?
do you want to share the internet from the windows machine?
if so then go here:

install an utility AnaligX in the machine thats gonna serve the Services.
 read its manual.

This is a pinout to make sure your crossover is correct.  This uses the EAIA standard

Hey All,
thanks for the comments, here's my responses:

Kennykoid,
yes, I have tried two crossover cables both of which have been used by others with no problems, but just to be sure, I tried connecting the computers usig a switch and two standard cables, but still no luck.

swapsthegreat,
See details at end of comment for ip details.  Also yes the led lights are on on both machines.  the two cards have 2 lights eachs. one is on constant and the other flickers now and again (same on both machines)

makana,
I need to set up a nistnet emulation box, i.e. a linux application that resides on a machine with two network cards and emulaties various network conditions for communications between the two computers connected to the cards.

tthayer,
The cables seem fine, I'm reasonably confident they are not the problem,

Thanks everyone for your comments so far

I see your problem.  Turn off DHCP on the Windows machind and statically assign an IP address of 192.168.1.102 and subnet mask of 255.255.255.0 and you should be good.  The windows machine is automatically configuring itself in the absence of a DHCP server.

Yep I would agree.  They are not on the same network ip structure.  Neet seeing the Linux config.  Been meaning to set one of those up and play around with it.

...or set the Linux box up with a 169.254.130.125 address/subnet mask of 255.255.0.0

Why You Should Analyze Threat Actor TTPs

After years of analyzing threat actor behavior, it’s become clear that at any given time there are specific tactics, techniques, and procedures (TTPs) that are particularly prevalent. By analyzing and understanding these TTPs, you can dramatically enhance your security program.

Ok problem solved,
CountRugen noticed something that I hadn't that was that the windows machine required a reboot (typical) after I set the address to static.  I had set it in the network settings but as you can see above the ipconfig did not notice the changes, but it did after rebooting.
There was still a slight problem though when I rebooted, the same problem as above but I figured out that linux box was mixing up the network cards.
There were 2 cards in the system, one £com and one Realtek and in Yast2 it told me that I had applied ip changes to the 3com card but those changes actually occurred on the Realtek card and vice versa.  So all was well and good when I swapped the cables.
As for the points allocation, I hope you think it was fair, but I awarded most to CountRugen because that comment pointed an oversight that needed to be resolved before I could get the system working.
I awarded the remaining points to tthayer and sirbounty because I found their posts to be extremely helpful in tracking down the solution and helped my understanding of the network details etc.
Thanks for all your help,
Stef

TRY THIS....!!!!!
CrossOver Cable:
END1: WhiteOrange/Orange/WhiteGreen/Blue/WhiteBlue/Green/WBrown/Brown
END2:WGreen/Green/WhiteOrange/Blue/WhiteBlue/Orange/Wbrown/Brown

Network Configuration.
PC1: (TCP/IP Properties)
IPADDRESS: 192.168.0.1
SUBNET: 255.255.255.0
GATEWAY: -none-

PC2:
IPADDRESS:192.168.0.2
SUBNET: 255.255.255.0

Ping first its IP Address. Then the oterPC.
If you've not recieve a reply. Maybe, their is a problem with your CABLE, or LAN card.
Another would be the DRIVER. Re-install the driver.
No need to restart windows when using Windows 2000 and Upper version.
In 98 you're required to restart, in order to apply the new settings.

I think the cable connection is wrong.
Try this Cabling method.

1) Brown White-Blue White
2) Brown - Blue
3) Blue White - Brown White
4) Green - Green
5) Green White - Green white
6) Blue - Brown
7) Orange White - Orange White
8) Orange - Orange

Add Static TCP/IP on both computers : 192.168.0.1 & 192.168.0.2
Subnet mask : 255.255.255.0 on both computer.
Restart and Ping to each other not with computer name but by IP Addresss..
I think this will work.....

Hi,
Cross over cabling is only to bring 2 systems into one network for routing to take place you require a router where you can configure routing protocols on router and then you can make use of these 2 systems as you like with your Router one and 2 way.

Hi,
Check whether your LanCards are working properly in both the computers if they are working properly then check your cable colour sequence for Cross Cabling and whether they are climpped properly or not and moreover you can check your lanCard connection is blinking or not once cable is plugged into LanCard and make sure you remove all the ip settings and just enter ip address followed by Subnetmask on both the systems (for example : 192.168.0.1;255.255.255.0 and 192.168.02;255.255.255.0).check and see you should be able to communicate between 2 systems.
