Does this mean the check in iputils is faulty w/r/t new kernels, or do new kernels have a *SERIOUS* regression?
The new kernels *DO NOT* have a serious regression, at least concerning this issue. If you search for this error message, you will see that it is printed for several of the network utilities if things like ping and other simple utilitoes are unable to reach their destination. Usually it means that you had some kind of network problem.
In this case 'serious network problem' simply meant that the host was unreachable -- which was why I was trying to 'ping' it in the first place (i.e. debugging what seemed to be a simplistic network problem). I didn't SERIOUSLY consider it likely that it was a kernel problem given the age of the utils -- just a bit odd that I'd never seen this message before with the opensuse13.1 release but then do with the 13.2 release. Does 13.2 ping come from a different package than 13.1 ping? Seems like at the very least networking in 13.2 took a step backwards (the various ifconfig/ifup/ifdown utils -- different package, no longer work either, as they did change package sources -- seems configuring network interfaces in 13.2 requires 'dbus' -- which doesn't work over networks. Sorta retarded that network relies on dbus which I've never been able to get to work over a network (i.e. desktop logging into suse machine that expects to use 'dbus' to talk to foreign (over network) dbus. Nice step backward. If a network is going to require dbus to work, might be nice to make sure dbus over a network works first... *sigh* Interesting article: http://darkmatters.norsecorp.com/2015/09/30/cellular-damage/ referring to 'cell phones', but pertinent to any self-updating software that increases the threat surface. Seems like having networking rely on 'dbus', is opening another layer of threat surface. Problem with PC-(linux+MS) SW devel today, is it's all about decreasing user control over their own devices and giving control to outsiders -- which creates new vectors that can also, often, be used for security breaches (even MS's update-channel has been used as an intrusion vector). Aren't the boundaries between dbus and kdbus in constant flux? I wonder how long it will be until PC's have as many threat vectors as cellphones? -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kernel+owner@opensuse.org
