[opensuse] confused by network setup
Hello: Sorry, but this is going to be a little bit long. I have the following problem in my openSUSE 11.2 system: I have an ADSL internet connection where I have login name and password for authentication. For the connection I created a DSL device and a provider in yast. The DSL device is configured as: PPP Mode: PPP over Ethernet, Activate device: On hotplug, and Enable device control for non-root users via kineternet option is enabled. The network card is configured in yast as follows: Network Settings/Overview window: name: xxx ethernet controller, IP Address: none device name: eth0 started automatically at boot Network Settings/Global options window: Traditional method with ifup enable IPv6 DHCP Client Identifier: left empty Hostname to send: AUTO Change default route via DHCP: not checked Network Settings/Hostname-DNS and Routing windows: default values Network Card Setup/Address window: No IP Address is (for Bonding Devices) is selected everything else is off/blank Network Card Setup/General window: Activate device: on hotplug Assign interface to firewall zone: External zone Network Card Setup/Hardware window: device name: eth0 After setting everything as above and clicking OK the network is set up, and the ADSL connection is made automatically. Network works well. I can hang up connection and can reconnect using kinternet. In kinternet/check connection everything seems to be OK, own address, name server address etc. But the problem is: When I turn the computer off and boot it again, the network is not getting configured, and I can not make the ADSL connection to the network. If I dial with kinternet its log says: pppd[0]: error sending pppoe packet: Network is down /var/log/messages has these lines: Oct 4 21:19:29 pc ifup: dsl0 name: DSL Connection Oct 4 21:19:29 pc pppd[3287]: Plugin rp-pppoe.so loaded.

But if I go to yast network settings and leave everything as is and click OK the network is restarted and works again. What can be the problem, and how could I fix it?

So the network devices are not getting started automatically. What do you have in /etc/sysconfig/network ?
ifconfig shows this:

Try activating your network devices with "ifup": ifup eth0 ifup dsl0 And let us know how it goes. -- Per Jessen, Zürich (11.8°C) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I assigned a statical IP address/subnet mask (10.200.1.1 /255.0.0.0) to the network card in yast and after rebooting the card was configured and network connection worked. Is there a drawback of assigning a static IP address? Might it be a bug that prevents network setup when no IP address is set for the card?

Ok, those were the two interesting ones.
# ifup eth0 eth0 device: nVidia Corporation CK8S Ethernet Controller (rev a2) eth0 Startmode is 'off' ^^^^^^^^^^^^^^^^^^^ That seems weird, isn't this your normal ethernet interface? I would expect it to have Startmode="auto" ?
# ifup dsl0 dsl0 name: DSL Connection interface dsl0 is up
kinternet tries to connect but can't. ifconfig still gives:
# ifconfig lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:362 errors:0 dropped:0 overruns:0 frame:0 TX packets:362 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:35975 (35.1 Kb) TX bytes:35975 (35.1 Kb)
I'm not very familiar with running DSL on a local device (I've only ever used a separate DSL router/modem), but I would expect some kind of point-to-point interface, probably pppoe0 - maybe a dsl0 interface too.
A googled in the meantime and found this:

I think you have quite likely hit a bug, I don't think this part of YaST has been tested much. I remember trying to get a pppoe setup to work with IPv6 maybe two years ago, the whole thing seemed a little flaky to me. -- Per Jessen, Zürich (18.9°C) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
