I have a 12.1 system which has one network interface wlan0 with an ipaddr of 192.168.1.8 and a default route of 192.168.1.1.

12.1? You should be asking on the factory mail list.

...

For some unknown reason, when I try to connect to at least one particular ipaddr, the os tries to arp 172.16.1.2. I have no idea where it's getting this addr.

That's a local subnet.

I'll look into the factory list, thanks. I found the issue. For whatever reason why it doesn't happen on 11.4, an incoming ICMP Redirect message is coming from the gateway to direct all traffic to a new gateway.

That definitely also happened on much older releases - it's a standard network feature. It may be disabled, but probably shouldn't be. Per Jessen, Zürich (11.9°C)

I only disabled it because the 'route' isn't getting flushed from the network stack when the network entry is removed. The redirect poisoned the network stack since I can't connect to the remote host unless I'm on the network where the redirect originated.

/usr/sbin/routef might be of some help. Ken Schneider

That didn't work. And my work-around of setting net.ipv4.conf.all.accept_redirects = 0 doesn't work either. R. -- Rich Coe rcoe@wi.rr.com -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
