The IP address and possibly other related information about the interface in the other network - even if you are not routing.
How does this happen, unless you're running a routing protocol such as OSPF? What mechanism is used to do this?
How does this compare to when you connect to the Internet via ISP? You're now connected to many networks and rely on a firewall to keep others out. Firewalls are now typically used on personal computers, even when connected to home networks. Also, the 2 interfaces are not bridged, as you seem to imply, so that's not how you'd have a leak. And that's exactly the problem. Linux bridges those interfaces. Not the whole networks but the interfaces present on the box are visible to all connected networks even when you did not ask for it.
It bridges interfaces when configured to do so. That's not the default. Interfaces are normally independent.
You may want to read up on how routers work.
Maybe you too ;-)
I'm a CCNA and have never heard of such a thing and I also frequently use Wireshark and haven't seen it either.
Read the other reply about weak host model. Supposedly this is not a bug but annoying design choice in Linux (different from eg. BSD). Thanks Michal -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
