Public bug reported: I routinely sit on our work guest network which has a 1 hour DHCP lease time.
What I'm noticing is that every hour skype and pidgin are reporting "buddy offline,.....,buddy online". What appears to be happening is the NetworkManager is (successfully) renewing the lease - but appears to trigger whatever APIs it normally triggers when network changes occur. In other words, renewing a DHCP lease seems to be treated the same as resetting a network interface I don't know if this is a bug or is expected behaviour, but from a user perspective I do not understand why successfully checking if the IP address you have is still valid should trigger anything: nothing has changed, so why "tell" other applications that something has? To put it another way, if I set a static IP, I bet these applications would no longer think network changes are occurring, so why can't the same thing happen with successful DHCP renewals Thanks for listening Jason ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: network-manager 0.9.8.8-0ubuntu7 ProcVersionSignature: Ubuntu 3.13.0-29.53-generic 3.13.11.2 Uname: Linux 3.13.0-29-generic x86_64 ApportVersion: 2.14.1-0ubuntu3.2 Architecture: amd64 Date: Fri Jun 13 08:47:36 2014 IfupdownConfig: # interfaces(5) file used by ifup(8) and ifdown(8) auto lo iface lo inet loopback InstallationDate: Installed on 2014-05-01 (42 days ago) InstallationMedia: Ubuntu 14.04 LTS "Trusty Tahr" - Release amd64 (20140417) NetworkManager.state: [main] NetworkingEnabled=true WirelessEnabled=true WWANEnabled=true WimaxEnabled=true ProcEnviron: LANGUAGE=en_NZ:en TERM=xterm PATH=(custom, no user) LANG=en_NZ.UTF-8 SHELL=/bin/bash SourcePackage: network-manager UpgradeStatus: No upgrade log present (probably fresh install) WifiSyslog: ftp_proxy: http://localhost:3128/ http_proxy: http://localhost:3128/ modified.conffile..etc.NetworkManager.NetworkManager.conf: [modified] mtime.conffile..etc.NetworkManager.NetworkManager.conf: 2014-05-02T16:40:21.190732 nmcli-dev: DEVICE TYPE STATE DBUS-PATH 98:D6:F7:D1:30:7B bluetooth disconnected /org/freedesktop/NetworkManager/Devices/7 wlan0 802-11-wireless connected /org/freedesktop/NetworkManager/Devices/1 eth0 802-3-ethernet unavailable /org/freedesktop/NetworkManager/Devices/0 nmcli-nm: RUNNING VERSION STATE NET-ENABLED WIFI-HARDWARE WIFI WWAN-HARDWARE WWAN running 0.9.8.8 connected enabled enabled enabled enabled enabled no_proxy: trimblecorp.net ** Affects: network-manager (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug trusty -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1329511 Title: dhcp lease renewal treated as equivalent to ifup?
