Networking Problems
Verdell Hicks
I have a problem figuring out the routing for my TCP/IP
network. Please don't laugh as I have read everything I could
find on TCP/IP and have tried many different things to no avail.
I think the problem is in my routing and you will soon see why, I
have however tried adding other things to my routing table and
this has still come up nil. So here goes. I have only two
machines. Yep two. These machines for the time being are not
connected to the internet. One machine is called Edge
[Edge.mine.net] the other is Foundation [Foundation.mine.net].
Here is the info for each. Please help me if you can and I would
be eternally grateful. I gave myself 1 whole month. It's time
to post the HELP!
Edge
This is a copy of what ifconfig produces on edge [IP 192.168.1.1]
lo Link encap:Local Loopback
inet addr:127.0.0.1 Bcast:127.255.255.255 Mask:255.0.0.0
UP BROADCAST LOOPBACK RUNNING MTU:2000 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0
TX packets:12 errors:0 dropped:0 overruns:0
eth0 Link encap:10Mbps Ethernet HWaddr 00:00:C0:3A:CF:96

Here is what route -n produces on edge;
Kernel routing table

Here is what ifconfig produces on Foundation IP 192.168.1.2
lo Link encap:Local Loopback inet addr:127.0.0.1
Bcast:127.255.255.255 Mask:255.0.0.0

Here is what route -n produces on Foundation;
Kernel routing table
Destination Gateway Genmask Flags MSS Window Use Iface
192.168.1.0 * 255.255.255.0 U 1436 0
0 eth0
127.0.0.0 * 255.0.0.0 U 1936 0
12 lo
default * * U 1436
0 0 eth0
This is after a fresh reboot. There is no 192.168.1.0
Each of the hosts file on each machine has the others
corresponding address and name in it. I assume my problem is the
routing. When I ping one machine from the other with the routing
as is I get the message network unreacheable. When i do a route
add 192.168.1.1 or 192.168.1.2 to both of them then when I do a
ping it just sits there. the pinger will show for instance 17
packets transmited and 0 returned and the pingee will show 17
packets recieved but none returned. This is the most frustrating
thing. Networking with only two machines and a protocol that I
have 3 books for. And it not working because NONE of these books
are very clear on private non-connected networks. In most cases
I read routing gets configured when you initialise the networking
interface, so unless you have multiple gateways or many subnets
with gateways you won't have to mess with it. Well, I've gotten
my frustrations out, so if you need any more info let me know and
I will forward it along.
