NIC Installation:
* you are using Red Hat Linux 6.0 or equivilant
* your Realtek nick is like mine and uses the rtl8139 driver.
*Remember you can use any driver with
this NHF, we are using the realtek driver as an example.
Steps:
-AS ROOT: Install module with
insmod rtl8139
-List the modules that are installed with lsmod
if you didn't get any errors during the module install and it was listed,
then the module should work.
-in a Xterminal: run
netcfg
You will need to edit the names
and interfaces tabs. You will be
editing the eth0 information. Use the settings that you received
from your ISP the same ones that you use in NT.
* If your NT connection "obtains IP information automatically",
then you will want to use DHCP for your "interface configuration
protocol"
* Click "save"
* Click "activate interface" in the interfaces tab. while you have eth0
highlighted.
* Test the interface. Open up an xterm, and ping something that you know.
(be sure to ping both by IP and by hostname)
[root@box /root]# ping www.linuxnewbie.org
PING linuxnewbie.org (199.78.176.193): 56 data bytes
64 bytes from 199.78.176.193: icmp_seq=0 ttl=240 time=147.0 ms
64 bytes from 199.78.176.193: icmp_seq=1 ttl=240 time=56.3 ms
[root@box /root]# ping 199.78.176.193
PING 199.78.176.193 (199.78.176.193): 56 data bytes
64 bytes from 199.78.176.193: icmp_seq=0 ttl=240 time=64.6 ms
64 bytes from 199.78.176.193: icmp_seq=1 ttl=240 time=60.7 ms
If you get responses from both IP and hostname, than you are all set
up.
If you get network is unreachable, you might need to add a default
route. (See adding route below.)
if you get a response from the IP but not from the hostname,
then you need to check your DNS settings inthe names[b]
tab in netcfg.
* Last thing that you should have to do, is tell your machine which
module to use when it tries to start eth0. You will do that by adding the
folowing line to your [b]/etc/conf.modules file.
alias
eth0 rtl8139
Adding routes
- If your machine doesn't know wich interface
to get to the network from, you will get a "Network is unreachable"
error. The following command will tell your machine to send all internet
bound packets out through your eth0 interface.
route
add default eth0
----------------------
That should do it.
Now, if you want other machines on this network to be able to see the
internet through the machine that we just set up, you will need to look
at the ip-masquarading NHF.
