    adsl connection with redhat 8.0


    I have been trying to get rh8.0 working with adsl. I am able to get an IP address but unable to ping anything, even the DNS. Here is what I have done. Originally, I had this machine set up to link to a cable modem as my lan router and gateway to the internet. Everything was fine. I moved. I now have Alltel dsl. I am using a speedstream 5200 usb/ethernet adsl modem by efficient networks. I have tried a couple things. I ran the adsl-setup from the rh8 distribution. I got an IP address but nothing further. I ran roaring penguin's rp-pppoe...rpm and went through the setup again. This time I was timing out when trying to connect. No IP address with this. Reading a few more howtos, I decided to go back to the first try. So, I have an IP address again. The ppp0 connection is listed as the default route. I don't know if this is the same as the default gateway. Also, eth0 is listed as not active. I have been assuming this is the way I want it. Can anyone offer any help? Thanks.

    Have you talked to your provider about install support via telephone?

    There are other options but since I didn't see it in you msg. I thought I'd start there.

    Is the DSL modem connected to your PC via ethernet or USB??

    If its ethernet, then eth0 should show up when you run "ifconfig".

    also, what output do you get with "iptables -L"?

    adsl connection with redhat 8.0

    I talked to my ISP. They were very nice, but naturally have no answers for Linux. I checked eth0, and it is inactive regardless if ppp0 is active or not. I tried to activate eth0 and could not. I should say that when I try to activate, it is through the GUI for network settings. eth0 does show up using ifconfig and looks good there, no dropped packets or anything. Yes, I am using the ethernet connection, not USB. Below is the output from iptables -L.
    Thanks, Scott

    For some closure on this, I thought I would post. After thinking about the routing I was
    asked about and looking around a bit, I realized my firewall was using eth0 as the default
    gateway instead of ppp0. I changed this in the firewall script and ping packets were
    flowing beautifully. That part seems fine now.

    Speedstream 5200

    I am using the same kind of modem/router as you from the same company. I have tried to use the Roaring Penguin RP-PPPOE, but am getting timed out as you were before you got connected.
    How can you check if eth0 is the default gateway instead of ppp0? How can you change this in the firewall script? I am a complete newbie at this Linux stuff. Any help would be greatly appreciated.

    use route commnad like this :

    route add default gw XXX.XXX.XXX.XXX

    you can use route to add/delete routing entiries to your routing table.
