network within a networkI am a college student living in a duplex. Our whole duplex has one
internet connection. I have a laptop with a wireless card and a
ethernet card. I use the wireless card to access the internet. I also
have a desktop with only a ethernet card that i am trying to connect to
my laptop. Im trying to make my own network to share the internet
connection with my desktop. My problem arises when i try to make my
laptop the host to my network, i think it tries to take the 192.168.0.1
ip address which is already taken by the router ( in other apartment).
so i get ip address conflictions. A...
I want to study linux network but I have not a networkHI,
I am using debian 3.0 as my linux PC and I want to study the linux

Is any emulation that can be done to construct a virtual network within
my PC?
Any help appreciated!

You can use Vmware (www.vmware.com), but it's quite expensive. The
workstation edition costs $189. But you can get a 30 day fully
functioning trial version.

You can do almost anything just over loop-back, like "ssh
localhost" no need for any emulation, you already have one.

Two network adapters on seperate networks problemGreetings. Here's my situation: I have a PC running SuSe 9.3 that has
two NIC's. One of these is configured with a static IP such as:
device: eth0
IP: 10.9.81.204
Subnet Mask: 255.255.255.192
Default Gateway: 10.9.81.193
This is an "isolated" network. By this I mean that the routers on this
network have extensive access control lists so that only certain
machines on this network can see other machines. There is no access
from this network to the public internet, (the proxy server for the
internet is blocked on this network).
My other NIC is configured to get an IP via DHCP (although I could get
a static IP if that would help). It gets an IP like:
device: eth1
IP: 10.9.16.140
Subnet Mask:255.255.255.0
Gateway: 10.9.16.1
This network does have a connection to the public internet through a
proxy server at IP 10.22.2.100.
I can ping and ssh to machines on both networks. Machines on both
networks can see me, even my samba shares. But, I cannot get to the
public internet from my machine, it seems that my connection to the
proxy server is blocked. I suspect it is because my default gateway is
going through eth0 onto the private network. If I remove the default
gateway entry, then I can get to the public internet, but I loose the
connection I have to machines on the "isolated" network network.
Is there some sort of solution that will allow me to have my default
network traffic go to the eth1 adapter configured via DHCP, and still
allow traffic to go ...
network problems with Mac Mini on PC networkIs the Mac (or Mac Mini) known to cause issues with certain kinds of

1pc, 2 network devices in same network -> ping problemHello,
Consider the following situation:
kernel 2.4
1 pc, 2 network devices
Both devices have an IP of the same network e.g.
net_device1 has IP 192.168.0.1
net_device2 has IP 192.168.0.2
This results in the following routing table
(dependent of which device is firstly initialized with ifconfig ...
up):
....
....
192.168.0.0 * 255.255.0.0 U 0 0 0 net_device2
192.168.0.0 * 255.255.0.0 U 0 0 0 net_device1
When pinging to net_device1,
net_device2 responds to the arp-request and the ping instead of
net_device1 (even when the cable of net_device1 is unplugged).
Thus net_device2 kind of becomes the "gateway" of network 192.168.0.0.
Net_device1 never responds.
How can I change this behavior to obtain that:
- net_device1 responds to an arp-request and a ping to 192.168.0.1
- net_device2 responds to an arp-request and a ping to 192.168.0.2 ?
This is needed for monitoring purposes (to be able to switch between a
main e.g. net_device1 and backup device e.g. net_device2).
Thx

Proper routes for linux machine with two network ports to same networkHi,
I run a Fedora Core 4 system with two network devices eth0 (assigned
10.10.10.30) and eth1 (assigned 10.10.10.31). The local network is
10.10.10.0, the gateway is 10.10.10.1
# route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use
Iface
10.10.10.1 * 255.255.255.255 UH 0 0 0
eth1
10.10.10.0 * 255.255.255.0 U 0 0 0
eth0
10.10.10.0 * 255.255.255.0 U 0 0 0
eth1
169.254.0.0 * 255.255.0.0 U 0 0 0
eth1

eth1
default 10.10.10.1 0.0.0.0 UG 0 0 0
eth0
Although rules to 10.10.10.0 exists for both eth interfaces, It seems
that traffic going to the local network at 10.10.10.* goes thru eth0 if
no interface specified. If I pull out the network cable at eth0,
ping 10.10.10.100 -> Destination Host Unreachable
ping 10.10.10.100 -I eth0 -> Destination Host Unreachable
ping 10.10.10.100 -I eth1 -> Works fine!
Similar problems exist for the internet outgoing connections with the
default and 10.10.10.1 gateway routes.
How do I add the routes properly so that the machine will look at which
interface is working or sort of, and choose the correct route?
Thanks for any pointers.

This mashine has a very low network bandwith ( needs several hours

A possible cause of that problem could be, that the networking switch

When I start the system I always get a window asking for my network

Is there any way of bypassing this window and proceed directly to

Network setup problem.First, let me say that I don't know a lot about networks, so forgive me
if I'm asking a stupid question. The apartment complex where I work
recently upgraded their network equipment, and when they finished, the
two computers in the community computer room no longer had internet
access. I took a look at the setup, and it appears to me that the two
computers in the office are plugged into two ports on a Cisco PIX 501
Firewall. Those computers still have internet access. A third port has a
Linksys 5 Port Workgroup Switch plugged into it, with the two community
computer room computers plugged into it. These computers can't access
the internet.
It seems to me that this configuration wouldn't work. Wouldn't the
router in the firewall see the two computers plugged into the switch as
one device asking to be assigned two ip addresses? Wouldn't this screw
things up? Or am I way off base here? Thanks for any input.
