ppp0 seems to be working, but can't browse the net

Hi,

Since I put my last help request on this newsgroup, I have been tyring
varios thing. I am running Redhat 8.0 kernal 2.4.20-19.8. I was trying
to install a secon nic on my system, and my ppp0 connection using eth0
got screwed. I removed the second nic, and tried to get things back to
as they were.

Now I think ppp0 is working, but I can't browse the web. Mozilla behaves
as if no connection has been established. Here is some info below. All
suggestions would be greatly appreciated or hints as to what could be
wrong or where to look.

[root@localhost sbin]# /sbin/adsl-connect
Using interface ppp0

So, I guess ppp0 is loggin into my Sympatico account, but for some
reason I can't browse the web.

Thanks in advance for suggestions on how to track down and solve the
problem,

BTW, my eth0 is configured to get its IP automatically using dhcp. I hope
that is a correct setting for this situation.

This doesn't make sense. Why do you show a different IP and peer? The
first one didn't show up in your route table.

It could be a matter of name resolution. Try pinging known IP addresses
to rule that out. I don't know DSL/PPPoE, but if it's like dialup PPP,
the option "usepeerdns" will get you a /etc/ppp/resolv.conf, and you can
use that by symlinking /etc/resolv.conf to that (for one example; there
are numerous ways to handle this.)

Again I don't know DSL. Does it need an IP at all? It is however quite
possible that this is causing the problem, because DHCP clients will
overwrite your /etc/resolv.conf. If the client is dhcpcd, you can use
the option "-R" to prevent this. See "man dhcpcd" or documentation for
the DHCP client you use.

The difference is because the "adsl-connect" command was followed by
disconnection, and then the rest of the messages are for a new "/sbin/ifup
ppp0" command. My IP changes with every connection, as it happens for all DSL
models I guess. Apologies for the confusion, I should have clearly mentioned
this.

Probably not. Probably just a routing problem. You need to make sure
that neither of your nics have a default route, or that you set up the
explicit route to the IP addresses your ppp connects to (in
/etc/ppp/ip-up)

Sounds like a problem with resolv.conf.

Fine you have a default route to the net through ppp.

Your ethernet is not connected at all. No routes through your ethernet.

Again, /etc/resolv.conf

No it is not. It has no connection at all.
Now, you need to tell us which connection, your ethernet or your ppp you
want to use to connect to the net. That will determine which your
default route should be.
