[TriLUG] PPPoE, adsl connection, RH 7.3

[Richard O. Hammer]

I've installed RedHat 7.3 on a system which has one network
card, and I'm having trouble getting my Roaring Penguin PPPoE
connection to the Internet working.  I'm trying to connect to
my DSL service with Sprint/Earthlink.  Before, when I had
RedHat 7.0 running on the same system, the adsl software
worked fine.  But there seems to be something new about 7.3
which is not working.

When I failed to get the connection going with the packages
included with 7.3, I followed advice at
<http://www.roaringpenguin.com/pppoe> and downloaded and
installed a new-old version, rp-pppoe-3.4-1.i386.rpm .  But it
is neither better nor worse, I don't think it changed
anything.

Anyhow, here are the symptoms:

adsl-setup runs fine and congratulates me on my success.

adsl-start seems to succeed.

After running adsl-start, ifconfig shows a connection
  ppp0  Link encap:Point-to-Point Protocol
        inet adr:63.173.123.59 P-t-P:63.173.123.1
Mask:255.255.255.255
        UP POINTTOPOINT RUNNING NOARP MULTICAST MTU:1492
Metric:1
        ...

63.173.123.59 is the IP dynamically assigned by earthlink.

adsl-status says the link is up and running on interface ppp0

tail /var/log/messages shows these messages (among others):
  pppd[]: Connect: ppp0 <--> /dev/pts/3
  pppd[]: PPP session is 8923
  pppd[]: Remote message: CHAP authentication success, unit
176
  pppd[]: not replacing existing default route to eth0
[192.168.0.2]
    /* I am suspicious of that message ^ there.  192.168.0.2
is the
       address I have assigned to this machine for my LAN,
connecting
       to a windows box.
    */
  pppd[]: local IP address 63.173.123.59
  pppd[]: remote IP address 63.173.123.1
  pppd[]: primary DNS address 63.162.197.69

But I can't do anything with this internet connection.  When I
try:
ping trilug.org , it responds
  ping: unknown host trilug.org

And when I try ping 63.162.197.69  (the earthlink DNS server)
it responds
  PING 63.162.197.69  from 192.168.0.2 : 56 bytes of data
  From 192.168.0.2 icmp_seq=1 Destination Host Unreachable
  ...


So it looks to me like perhaps my machine is identifying
itself to the earthlink server as 192.168.0.2 instead of as
63.173.123.59, which is probably a mistake.

But where/how do I fix this?

Thank you,
