This behavior should be reversed, as ip has been preferred over ifconfig for several years now. As an example of why, lxc-net breaks the network setup within virtualbox guests. After starting lxc-net, the route table looks like: ubuntu@vivid-i386:~$ route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 10.0.2.2 0.0.0.0 UG 1024 0 0 eth0 10.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lxcbr0 10.0.2.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 169.254.0.0 0.0.0.0 255.255.0.0 U 1000 0 0 eth0 This is despite the following settings in /etc/default/lxc-net: LXC_BRIDGE="lxcbr0" LXC_ADDR="10.0.3.1" LXC_NETMASK="255.255.255.0" LXC_NETWORK="10.0.3.0/24" Switching the order in ifup and ifdown to try using ip first results in the correct netmask being applied: ubuntu@vivid-i386:~$ route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 10.0.2.2 0.0.0.0 UG 1024 0 0 eth0 10.0.2.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 10.0.3.0 0.0.0.0 255.255.255.0 U 0 0 0 lxcbr0 169.254.0.0 0.0.0.0 255.255.0.0 U 1000 0 0 eth0 Looking at sh -x output when running lxc-net manually, it *looks* like ifconfig is being invoked correctly, so I don't know why it's getting the netmask wrong: + use_iptables_lock=-w + iptables -w -L -n + [ -d /sys/class/net/lxcbr0 ] + brctl addbr lxcbr0 + echo 1 + [ ! -d /run/lxc ] + ifup lxcbr0 10.0.3.1 255.255.255.0 + which ifconfig + [ 0 = 0 ] + ifconfig lxcbr0 10.0.3.1 netmask 255.255.255.0 up + return ProblemType: Bug DistroRelease: Ubuntu 15.04 Package: lxc 1.1.0-0ubuntu1 ProcVersionSignature: Ubuntu 3.18.0-13.14-generic 3.18.5 Uname: Linux 3.18.0-13-generic i686 ApportVersion: 2.16.1-0ubuntu2 Architecture: i386 Date: Sat Feb 21 00:13:27 2015 InstallationDate: Installed on 2014-12-12 (70 days ago) InstallationMedia: Ubuntu 15.04 "Vivid Vervet" - Alpha i386 (20141212) ProcEnviron: TERM=screen SHELL=/bin/bash PATH=(custom, no user) LANG=en_US.UTF-8 XDG_RUNTIME_DIR=<set> SourcePackage: lxc UpgradeStatus: No upgrade log present (probably fresh install) defaults.conf: lxc.network.type = veth lxc.network.link = lxcbr0 lxc.network.flags = up lxc.network.hwaddr = 00:16:3e:xx:xx:xx modified.conffile..etc.default.lxc: [modified] mtime.conffile..etc.default.lxc: 2015-02-20T18:15:56.552501 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxc/+bug/1424143/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
