Ethernet Card

[Kyle D. Harris]

Morning all-
In Redhat 9.0 Network device control. My ethernet cart, i go to the "route" tab and I'm wondering if I need to add a Destination Network? Whatever that means.

I am trying to establish a connection to our network were on with a server i'm building which has it's own static IP address and a lan line to our network. Can anybody tell me if I need to add a Destination Network, Prefix (netmask) and a Gateway at this tab in Network Device Control. Thanks!

I don't know specifically about Red Hat and it's funky network GUI but I would guess you do need to add a destination network.

Basically, for routing, you need to tell the system where to route packets for various networks.

So, Destination means "packets that are going to be sent here" and Gateway means "the router that knows how to send things to the destination"

You don't need a route for each IP address though, just for the network so if your ip address was 10.80.132.1 and you wanted to talk to things on the 192.9.30.XXX network, you'd find yourself a router that was connected to both (or at least knew how to get between the two) and the IP address of this was 10.80.132.11 you would need to set up something like..

Destination would be 192.9.30.0 and gateway would be 10.80.132.11

The netmask will almost certainly be whatever the netmask is for your machine.

Hopw this helps a bit.

Thanks Mark. Quick Question you probly know already.... How do you make a link to another directory.

IE. i want /usr/local/catalina directory to point (->) to another directory.. Thanks

[Kyle D. Harris]

Nevermind, i figured it out. Thanks

ln -s /usr/local/catalina

Kyle,

You probably know this but just a pointer to the "fancy gui/tui network tools under RedHat Linux 9.0)

From X from menu --> system tools --> Red Hat network

From shell
# redhat-config-network

Hello Kyle,

in a simple case you will have two routes. One for the network that your system is part of. This is essentialy your own network interface.
Addtionally you should have a "default" gateway (i.e. router) that allows you to reach all the other networks, i.e. the routes for my laptop here at home look like this:
10.0.0.0 0.0.0.0 255.0.0.0 eth0
default 10.0.0.253 - -


I use a 10.x.x.x network at home (no I do not have that many systems ;-) that the laptop is directly connected to. All the rest of the world is accessible via my router (10.0.0.253), which is the default gateway.

Details on the router and network mask should be available from your networking group.

Guys-
I just looked at another server running 9.0 right next to me. From that server i'm able to ftp to redhat just fine.
From the server i'm building it says "network host unreachable" when i try to ftp to anything, or ping.

So I looked at the settings of both, the one that works and the one i'm building giving me problems. All the settings are the exact same in the Network Configuration except of course the different Static IP's. Could there be another reason I can't connect to the outside world or even another server right next to me on the same network!? Thanks!

Kyle,

Perhaps you forgot to put theses node name in the /etc/hosts file

-----------< example /etc/hosts >------------
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
10.10.10.19 nodea.ourdom nodea
10.10.10.20 nodeb.ourdom nodeb

-------------< end/etc/hosts >--------------

Just to cover the basics:

Have you started IP (inetd or xinetd)?
Are you able to talk to the loopback device
ping 127.0.0.1 or telnet 127.0.0.1?
