[opensuse] Martian Invasion!
My log is filling up with Martian Source message. Dec 7 13:14:28 poulsbo kernel: [ 1318.735298] martian source 192.168.2.255 from 192.168.2.1, on dev wlan0 Dec 7 13:14:28 poulsbo kernel: [ 1318.735322] ll header: ff:ff:ff:ff:ff:ff:00:10:18:19:b9:5b:08:00 My wireless router is serving as an access point, on the same subnet as my wired connection. I'm actually wired on eth0, but unless I remember to click on the Knetworkmanager tray applet and UNCHECK Enable wireless wlan0 starts posting martian messages, and then tries to associate with with the wireless router. Is there a setting I can make to cause WiFi not to be enabled when the Wired interface is up? Is there a setting to disable these martian source messages? And why am I getting them? -- A computer without Microsoft is like a chocolate cake without mustard. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

The IFPLUGD_PRIORITY helped here in the past. But be warned as this might not work with NetworkManager. I've not tested it. See man 5 ifcfg. I'm curious regarding the right NetworkManager approach to solve this issue. Lars -- Lars Müller [ˈlaː(r)z ˈmʏlɐ] Samba Team SUSE Linux, Maxfeldstraße 5, 90409 Nürnberg, Germany

echo "0" > /proc/sys/net/ipv4/conf/all/log_martians THis does not fix the problem of course. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Ah, ok.. But is that the proper thing to do, or is it a bandaid? Why does it think its a martian source? My understanding of martian source was a packet received with an impossible source IP. -- A computer without Microsoft is like a chocolate cake without mustard. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

It simply drains the wound... which keeps bleeding.

Or that comes via an interface where it shouldn't. - -- Cheers, Carlos E. R. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (GNU/Linux) iEYEARECAAYFAksdo8cACgkQtTMYHG2NR9XRlwCfeLpt2/EANLOWqblqfFXqvQ4S 4+MAnRDIMqHD/08gIw37i7HRfM6omJ5i =M0Ic -----END PGP SIGNATURE-----

Right. Since my Wlan0 is in the same subnet as my wired connection it seems that something in the TCP stack is calling anything from that subnet a martian source which is in error. There are two potential problems here: 1) Nothing in KnetworkManager allows you to specify that Wlan0 should not be allowed to come up if eth0 is also up. 2) Two interfaces on the same subnet seem to trigger martian source messages. There are a lot of places that bridge the wifi onto the LAN by setting the wireless up as an access point, rather than a true router. Maybe I should file a bug report against KnetworkManager?
