Package: network-manager
Version: 0.8.1-6
Severity: normal
On my system, I have two interfaces configured in /e/n/i, one with a default
gateway, and one without a default gateway. Network-manager makes up a non-
existent default gateway for the interface with no gateway, and uses that as
the default route.
/etc/network/interfaces:
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 192.168.2.99
netmask 255.255.255.0
gateway 192.168.2.1
auto eth1
iface eth1 inet static
address 192.168.23.1
netmask 255.255.255.0
pre-up /usr/local/sbin/firewall.rules
ifupdown does it right:
# route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
# ifup -a
# route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.23.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1
192.168.2.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
0.0.0.0 192.168.2.1 0.0.0.0 UG 0 0 0 eth0
# ifdown -a
# route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
#
Network-manager does this:
# route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
# /etc/init.d/network-manager start
Starting network connection manager: NetworkManager.
# route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.23.0 0.0.0.0 255.255.255.0 U 1 0 0 eth1
192.168.2.0 0.0.0.0 255.255.255.0 U 1 0 0 eth0
0.0.0.0 192.168.23.1 0.0.0.0 UG 0 0 0 eth1
Which is interesting and wrong ;)
/var/log/daemon.log says (among other things):
Mar 10 16:53:38 radon NetworkManager[29457]: <info> Policy set 'Ifupdown
(eth1)' (eth1) as default for IPv4 routing and DNS.
Cheers,
