Yesterday I installed the last kernel Update (3.7.10-1.11) now I have a full messages log file with

With kernel 3.7.10-1.4 this Problem don't exist?

Could you compare value of log_martians on both kernels?

Can you check "grep -r log_martians /etc/sysctl.*" ? If there is a file setting it to 1, you can check what package does it belong to, check its mtime and compare the timestamp with entries in /var/log/zypp/history Michal Kubeček -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kernel+owner@opensuse.org

log_martians are set by default by SuSEfierwall2 service (unless explicitly disabled). Did you have firewall active before? If it was disabled before installing updates and became enabled after it is a bug. -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kernel+owner@opensuse.org

Irrespectively of why it is suddenly logged - this indicates possible network misconfiguration. Could you show "ifconfig -a" output? -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kernel+owner@opensuse.org

With kernel 3.7.10-1.4 this Problem don't exist?

It is unlikely something to be broken in the networking stack. Better question to ask is who is 192.168.100.100 and why it started telling about itself to be 192.168.100.255...

I may have overlooked something but from the source it looks like this might just mean that a packet from 192.168.100.100 to 192.168.100.255 has been received on an interface RP filter considers wrong. Output of "ip addr show", "ip route show" and "ip neigh show" would definitely tell us more.

So the problem is that a (broadcast) packet from you sent to eth0 was received on eth1 which RP filter doesn't like. I dare to guess that you connected both eth0 and eth1 to the same ethernet segment. It is is not necessarily wrong and there are legitimate reasons to do that (but perhaps bonding might be more suitable solution). Anyway, in such case (as in many others), RP filter should be either disabled or at least set to loose mode, i.e. rp_filter sysctl should be set to 0 or 2. Unfortunately the default in OpenSuSE is 1 (strict mode).

OK, thak's I search in google ;) This is for me, a mystery Situation. I make yesterday a Test, I installed the system new only with one NIC (no seperate IPv6), and now the "martian_source" Log is gone again (?). Have any a link for Information or tests for this situation, I have a XEN SLES Test Installation with the same Problem, full running logs on all Instances :-(. I don't remember is this starting with a kernel update or my IPv6 config? -- mit freundlichen Grüßen / best Regards, Günther J.

I make yesterday a Test, I installed the system new only with one NIC (no seperate IPv6), and now the "martian_source" Log is gone again (?).

This makes sense - as I explained in previous mail, in your case the "martian" was a a packet sent by you to one interface and received on another, most likely connected to the same ethernet segment. If you have only one interface, this cannot happen.

No I have two, I have configured the first for internal IPv4 and the second should be a external IPv6 only Interface. But I mean I do wrong or i can't understand this Situation (?). In my Xen Situation I have three Bridges 1 x IPv4 external 1x IPv4 internal and a external IPv6 For me I mean, it is a Problem to separating clear IPv6 and IPv4? -- mit freundlichen Grüßen / best Regards, Günther J.

I don't see a reason for it but it (as such) is not a problem. But if you want to connect two interfaces into the same ethernet segment, you need to turn of the RP filter (or at least switch it to loose mode).
