Sorry about the "j" - dvorak artifact....
Okay, let me try again.
First, here's my (new) /etc/hosts file:
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 mhrichter localhost localhost.localdomain
#192.168.0.100 mhrichter mhrichter.adsl.irvine.sbcglobal.net
::1 localhost6.localdomain6 localhost6
If I run ifup eth0, here's what I get:
eth0 Link encap:Ethernet HWaddr 00:1E:90:F3:D2:8D
inet addr:192.168.0.100 Bcast:192.168.0.255 Mask:255.255.255.0
inet6 addr: fe80::21e:90ff:fef3:d28d/64 Scope:Link

RX bytes:7118384647 (6.6 GiB) TX bytes:413380509 (394.2 MiB)
Interrupt:153 Base address:0xc000
With this setup, I can login to the DSL modem, which shows the
following configuration:
DSL UP
Connection UP
User ID xxxxxxx at sbcglobal.net
Connected at 1536 Kbps (downstream)
384 Kbps (upstream)
IP Address 69.234.16.38
IP Gateway 69.234.31.254
DNS Servers 68.94.156.1 dnsr1.sbcglobal.net
68.94.157.1 dnsr2.sbcglobal.net
Mode PPP on the modem (Public IP for LAN device)
Timeout Never
Modem Information
Modem Name SpeedStream
Model 4100
Serial Number 20013A3E0A514
Software Version1.0.0.53
MAC Address 00:13:A3:E0:A5:14
First Use Date 2006/10/31 00:38:02 GMT
Local Network
Modem IP Address 192.168.0.1
Ethernet Status Connected
In this shape, I can ping, say, google.com from the modem and get a response.
But, when I run dhclient, I get this:
# dhclient

For info, please visit http://www.isc.org/sw/dhcp/
/sbin/dhclient-script: configuration for vmnet8 not found. Continuing
with defaults.
/etc/sysconfig/network-scripts/network-functions: line 78: vmnet8: No
such file or directory

DHCPACK from 192.168.0.1
bound to 69.234.16.38 -- renewal in 291 seconds.
And after that I can't reach the modem or the internet. If I run
ifdown eth0 and then ifup eth0, I get the 192.168.0.100 IP address
back, and I can reach the modem, but not the internet.
(So I'm back on the Windows machine to send this.)
This probably seems pretty basic to many of you, but I'm still a
neophyte at the details of IP under Linux. IOW, I'm lost. None of
this was any kind of problem before I reset/mangled the router.
One other question: I notice that the router claims to be 192.168.0.1,
but so does the modem. Could that be part of the problem, i.e.,
should I change the router's IP address to something else? I remember
it was 192.168.0.2 before the fiasco....
Thanks again.
