Hi Greg, This is getting to be a long story, so I'll only include the essentials from previous mails...If interested,here is what is in the modems internal software: PPP (VPI 8, VCI 35) ipa ipa 150.101.208.30 255.255.0.0 eth0 10.0.0.138 255.0.0.0 loop 127.0.0.1 255.0.0.0 auto DHCP domain name :lan hostname: user 10.0.0.1Okay, we have an external address (150.101.208.30) and an Internal address (10.0.0.138). Do you have 10.0.0.138 as your default gateway on the Mandrake box? In /etc/sysconfig/network you should have 'GATEWAY=10.0.0.138' and 'GATEWAYDEV=eth0'Is your RedHat 8 installation running its own DHCP server? Do you have any messages in '/var/log/messages|grep -i dhcp' on theWhen installing Mandrake, I have selected (when setting up net/internet)
the ethernet option, and selected bootp/dhcp instead of entering any
details. This is how Red Hat is configured (ethernet connection/dhcp)
and works no probs. After this, booting into MK9, internet does not
work. When it is booting, the detection of eth0 fails. Running
ifconfig in MK9, shows up only the "lo" details, and eth0 is not
running.
Mandrake box?
As a result, obviously no connection. Does not matter howmany different ways I configure the connection through the wizard, it
still does not work, even when I select ADSL, and choose DHCP.....
If I run ifup eth0, it fails. When I run 'ifconfig eth0 -pointopoint
10.0.0.1 netmask 255.0.0.0', it brings eth0 up, but still does no good,
and when I run the internet wizard, if knocks eth0 out, and puts it down
again.Mmmmmmmmm, the way I read the -pointopoint keyword in the docs for ifconfig, what you are doing here is attempting to set the address for the other end of the link. Now, I haven't been following this thread until now, so I'm not sure if you've been told specifically to use -pointopoint, but I don't think that this is doing what you want...To me that suggests that RH is using 10.0.0.1 as gateway. If I'm wrong, please someone correct me.When I bring up ifconfig in RH8, these are the addresses that come up: eth0 inet addr :10.0.0.1 Bcast 10.255.255.255 Mask 255.0.0.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 lo inet addr : 127.0.0.1 Mask 255.0.0.0
Here, RH is 10.0.0.1, the gateway should be the internal address of the router, which is 10.0.0.138.Please note with the above, that when running ifconfig eth0 -pointopoint 10.0.0.1 netmask 255.0.0.0 in mandrake, the 'UP BROADCAST RUNNING' section has a word 'NOTRAILERS' in it. Does this have a critical part to play?? This is one difference between the RH8 and MK9 ifconfig display.Google tells me that NOTRAILERS means that the interface doesn't support trailer encapsulation. Don't ask me what that means :) I don't think it is important here, however.Forgive me from snipping from here to the end, but I think that the mainAnne,
as far as I know, the eth0's address is automatically assigned? (dhcp)
and being the only device on the network in redhat, it gets an address
of 10.0.0.1. The router/modems address is 10.0.0.138. I use this
address (when eth0 is working) in my browser to get into the
configuration of the router. This brings up the routers menu (which is
web site design based) to configure everything.
problem here is DHCP. Your router needs to get its external address by
DHCP from your ISP, but if it is also serving DHCP to the lan, you could
have a conflict if you are also serving DHCP in Mandrake. This may not
be the case, however, but I would try the following:
Turn off dhcpd in Mandrake and let your nic get an IP address from the
DHCP server in the router, if it has one...
Otherwise, set a static IP on your nic of 10.0.0.1 and make sure that
your gateway is set to 10.0.0.138 and dev eth0.
I hope this helps,
Kind regards,
John...
