ubuntu 9.04 bridge的設定 - Linux

附上設定2跟設定3的ifconfig以及route資訊

設定2時 經過重開機後

ping不到 DNS server

ifconfig:
br0 Link encap:Ethernet HWaddr 00:24:8c:1b:66:f5
inet addr:10.6.31.202 Bcast:10.6.31.255 Mask:255.255.255.0

eth0 Link encap:Ethernet HWaddr 00:24:8c:1b:66:f5

下略..

route:
Destination Gateway Genmask Flags Metric Ref Use Iface
10.6.31.0 * 255.255.255.0 U 0 0 0 br0
10.6.31.0 * 255.255.255.0 U 1 0 0 eth0
192.168.122.0 * 255.255.255.0 U 0 0 0 virbr0
link-local * 255.255.0.0 U 1000 0 0 br0
default 10.6.31.1 0.0.0.0 UG 0 0 0 eth0
default 10.6.31.1 0.0.0.0 UG 100 0 0 br0


使用設定3 經過重開機後

ping不到DHCP server
ping的到DNS server
別台電腦ping不到這台機器

但是如果經過 sudo /etc/init.d/networking restart

則ping的到DHCP server
別台電腦也ping的到他了
剛剛的新發現

ifconfig:
br0 Link encap:Ethernet HWaddr 00:24:8c:1b:66:f5
inet addr:10.6.31.202 Bcast:10.6.31.255 Mask:255.255.255.0

以下省略..

route:(這是經過重新啟動networking的)
Destination Gateway Genmask Flags Metric Ref Use Iface
10.6.31.0 * 255.255.255.0 U 0 0 0 br0
192.168.122.0 * 255.255.255.0 U 0 0 0 virbr0
link-local * 255.255.0.0 U 1000 0 0 eth0
default my.router 0.0.0.0 UG 100 0 0 br0

route:(未重新啟動networking)
Destination Gateway Genmask Flags Metric Ref Use Iface
10.6.31.0 * 255.255.255.0 U 0 0 0 eth0
10.6.31.0 * 255.255.255.0 U 0 0 0 br0
192.168.122.0 * 255.255.255.0 U 0 0 0 virbr0
link-local * 255.255.0.0 U 1000 0 0 eth0
default my.router 0.0.0.0 UG 100 0 0 br0
default my.router 0.0.0.0 UG 100 0 0 eth0


額外資訊:使用brctl show所看到的東西 設定2跟設定3都是一樣的



我想問的是

為什麼我用網站上教的設定方法會出現上網問題

另外

假如像我使用設定3的話

有成功的把primary interface設定成bridge嗎?

謝謝
