When I installed 11.2 I allowed the installer to auto configure hardware and obviously had the ‘enable IPv6’ checkbox checked so I have /dev/br0 and /dev/eth0 where eth0 gets the IPv6 address and br0 gets the IPv4 address.
My machine is behind a router so it’s local subnet of a 192.168.xxx.xxx. Is there really a need to have IPv6 enabled on a LAN and how can I disable it and remove the bridged connection?
Also, the YaST manager says that the network card isn’t configured, but it’s only reading from eth0 and br0 is nowhere to be found in YaST.
Ok so I went into YaST. Curiously the ethernet device was listed as ‘Not Configured’. So after adding some basic config options the Global Options tab appeared and I unchecked IPv6.
This did NOT remove the bridged connection which is listed as br0.
After making the changes YaST said I needed to reboot, and so I did. After rebooting I lost all Internet connectivity and have the following:
suse:~ # ifconfig
br0 Link encap:Ethernet HWaddr 00:19:21:C1:66:46
inet addr:192.168.2.32 Bcast:192.168.2.255 Mask:255.255.255.0
inet6 addr: fe80::219:21ff:fec1:6646/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

TX packets:30 errors:0 dropped:0 overruns:0 carrier:0
RX bytes:1348 (1.3 Kb) TX bytes:7587 (7.4 Kb)
So I took down br0 (which also took down eth0) and then brought only eth0 back up using:
suse:~ # ifdown br0
suse:~ # ifup eth0
eth0 device: Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ (rev 10)
DHCP4 client is already running on eth0
IP address: 192.168.2.32/24
The message said that eth0 was already running but I could not get any Internet connectivity until I used ifup.
So I’m still back to asking the same question:
How can I get rid of the bridged connection (/dev/br0)?
Moved to ifcfg-br0.original and moved it out of /etc/sysconfig/network
I think that will fix it. Possibly a bug in the gui applet to configure network devices?
I’m still trying to get used to the new gui apps to manage all this stuff, and coming from Red Hat/Fedora and Ubuntu they seem quite foreign and (honestly) don’t appear to work quite as well. YaST has left me unimpressed so far. I had an issue with it not being able to retrieve info from one of the repositories (and thereby bombing out), and just now noticed yet another repository is causing it grief, but that’s another topic and thread.
I have other issues too, but not yet sure if they’re related to KDE 4 or if it’s an openSUSE issue. Still I’m not going to revert back to Fedora or Ubuntu just yet.
