[Bug 1879211] Re: Charging my cellphone through usb breaks internet connection.
@AlexMurray Genuine question. Does this mean that I shouldn't connect untrusted usb devices to my computer because it can unilaterally decide to snoop my traffic? So far my understanding has been that usb devices cannot run arbitrary programs and are thus safe to connect, with the exception of specific security exploits. This counters my expectations because a usb device would not need to rely on an exploit to compromise my computer, just legitimately use a feature. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1879211 Title: Charging my cellphone through usb breaks internet connection.

[Bug 1879211] Re: Charging my cellphone through usb breaks internet connection.
Sensible. If that were the case, a solution would rely in the capacity of the network manager to detect that the new route does not work,(and that the previous one did) My naïve solution would be to ping a reliable server (I use 8.8.8.8) and delete the new route if it timesout. Additionally, if the new cabled connection were successful initially, but later stopped working, shouldn't the network fallback to the previous connection? A similar thing already happens when multiple dns servers are specified. 2 functionalities failed for this bug to occur. (a third one if you count my phone presenting itself as a router when it can't do that, but that's not within Ubuntu's jurisdiction... is it?) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1879211 Title: Charging my cellphone through usb breaks internet connection.

One more thing - I expect your phone has USB Tethering enabled - and so presents itself as an rndis USB/ethernet device - and then network manager uses this as a preferred interface to route traffic through rather than the wireless interface. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1879211 Title: Charging my cellphone through usb breaks internet connection.

[Bug 1879211] Re: Charging my cellphone through usb breaks internet connection.
This doesn't seem like a security issue to me - I believe this is the default behaviour when using network manager for tethering - it will route traffic via the tethered device. I am reassigning this against network-manager which is likely doing the route setup. ** Information type changed from Private Security to Public ** Package changed: iptables (Ubuntu) => network-manager (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1879211 Title: Charging my cellphone through usb breaks internet connection.
